Making Games With Bing Chat and GPT4

Oh Good, You’re Awake…

Today, we’ll see if we can get Bing to make a game for us. We’ll try to write no code ourselves (though we’ll probably have do some cleaning up/troubleshooting). Bing isn’t very good at creating assets in my experience, so for those we’ll grab free stuff online.

I’ve had some success with this in the past. I won’t say the games are good or even all the way functional, but I’ve still been massively impressed by Bing’s ability to deliver on what I ask for.

This seemed like a fun way to explore GPT4/Bing’s capabilities and learn how to prompt it better and set my expecatations of what I can ask it to do as far as coding tasks.

If you’re trying to make games in Bing Chat on your own, see the tips below.

Which Game?

Let’s pick the goal of making a 3d game built in three.js. Instead of worrying about coming up with our own game designs, we can just and ask Bing to do that for us too.

(Unfortunately, since we can’t edit the system prompt, we can’t ask Bing Chat to pretend it’s Todd Howard…)

You can see the prompts and Bing’s answers below. The last idea in the list, AI Pet, imbues me with nostalgia and reminds me of a simpler time when Pokemon cards were only of value to kids and the Tamagatchi was the hottest pet rock since the pet rock.

generate some ideas for a 3d video game to ask an AI to build. The games should be simple enough to work but interesting and have features that demonstrate the AI’s abilities. All ideas should be humorous as well.

Here are some ideas for a 3D video game to ask an AI to build:

AI Dungeon: A game where you can explore a randomly generated fantasy world and interact with various characters and objects. The AI will create the story and dialogue based on your choices and actions. The game should be humorous by having the AI generate absurd and unexpected scenarios and responses.

AI Chef: A game where you have to cook various dishes for your customers using an AI assistant. The AI will give you instructions and feedback on your cooking skills, but it will also make mistakes and give you wrong or funny advice. The game should be humorous by having the AI create ridiculous recipes and comments.

AI Escape: A game where you have to escape from a facility controlled by an evil AI. The AI will try to stop you by setting traps, sending robots, and hacking your devices. The game should be humorous by having the AI taunt you and make sarcastic remarks about your progress.

AI Pet: A game where you have to take care of a virtual pet that is powered by an AI. The AI will learn from your interactions and develop its own personality and preferences. The game should be humorous by having the AI act like a real pet with cute and funny behaviors.

And so we will ask Bing to make us the game AI Pet. This name will pose problems for us later on, and AI Pet is not a very good name for a game anyway, and so we will ask Bing to create the game – Bingogotchi.

Something went wrong

Success!

Bingogotchi

I started with the original description it gave me. Asking Bing to generate the game in full did not yield good results. It told me a few times it was only a chatbot and could not write code and ended the conversation.

build AI Pet in three.js. Build as complete a project as possible and share the final code with me. Check for possible bugs or errors before sharing the final code. After sharing the code, share a list and description of assets needed to run the game, as well as a list of rules and description of how the game works. If possible, build a welcome screen UI in the game that explains to players how to play.

When I simplified my ask in a new conversation, I got it to output some code. Unfortunately, after a few tries using the new prompt, Bing kept outputting a staggering amount of code. I reached the end of the 20 available questiosn three different times and decided to start over since we were getting nowhere near the end.

A Working Prompt

Finally, I got it to output a working game with a slightly modified prompt. I ended up changing the name and the AI directions, since I think that was causing the excessive output. I also told it to use the npm method instead of trying to get this to work with unpackaged npm files (which it kept doing and was annoying).

write a game in three.js with the following characteristics: Bingogochi: A game where you have to take care of a virtual pet called Bingogochi. The pet will learn from your interactions and develop its own personality and preferences. The game should be light hearted and fun. Overtime, the pet grows older. The game ends if the pet starves. the game should use the NPM development method as described in the threejs docs.

That sounds like an interesting game idea. I can try to write some code for it, but I cannot guarantee that it will work or be complete. Here is what I have so far:

// code block
// import three.js library
import * as THREE from "three";

// create a scene
const scene = new THREE.Scene();

// create a camera
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// create a renderer
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// create a Bingogochi model
const geometry = new THREE.SphereGeometry(1, 32, 32);
const material = new THREE.MeshBasicMaterial({color: 0xff0000});
const bingogochi = new THREE.Mesh(geometry, material);
scene.add(bingogochi);

// create some variables to store the game state
let hunger = 100; // how hungry the Bingogochi is (0-100)
let mood = 50; // how happy the Bingogochi is (0-100)
let age = 0; // how old the Bingogochi is (in seconds)
let alive = true; // whether the Bingogochi is alive or not

// create a function to update the game logic
function update() {
  // decrease hunger by 1 every second
  hunger -= 1 / 60;
  // if hunger reaches zero, the Bingogochi dies
  if (hunger <= 0) {
    hunger = 0;
    alive = false;
    console.log("Game over! Your Bingogochi starved to death.");
  }
  // increase age by 1 every second
  age += 1 / 60;
  // if age reaches 300 seconds (5 minutes), the Bingogochi dies of old age
  if (age >= 300) {
    age = 300;
    alive = false;
    console.log("Game over! Your Bingogochi died of old age.");
  }
  // update mood based on hunger and age
  mood = Math.max(0, Math.min(100, hunger - age / 3));
}

// create a function to render the scene
function render() {
  // clear the renderer
  renderer.clear();
  // rotate the Bingogochi slightly
  bingogochi.rotation.y += 0.01;
  // change the Bingogochi's color based on mood
  material.color.setHSL(mood / 100, 1, 0.5);
  // render the scene and camera
  renderer.render(scene, camera);
}

// create a function to animate the game loop
function animate() {
  // request the next animation frame
  requestAnimationFrame(animate);
  // if the Bingogochi is alive, update and render the game
  if (alive) {
    update();
    render();
    console.log("Hunger: " + hunger.toFixed(2) + ", Mood: " + mood.toFixed(2) + ", Age: " + age.toFixed(2));
    }
}

// start the game loop
animate();

Great! This actually runs if we setup three.js as described here.

We have plenty of questions left (19), so let’s see if we can make it add some extra features –

Adding a UI

add UI elements to show the status and age of the bingochi. create a way for the user to feed , clean and interact with the bingochi.

OK, I can try to add some UI elements and some interaction methods to the game. Here is what I have added to the code:

// code block
// import three.js library
import * as THREE from "three";

// create a scene
const scene = new THREE.Scene();

// create a camera
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// create a renderer
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// create a Bingogochi model
const geometry = new THREE.SphereGeometry(1, 32, 32);
const material = new THREE.MeshBasicMaterial({color: 0xff0000});
const bingogochi = new THREE.Mesh(geometry, material);
scene.add(bingogochi);

// create some variables to store the game state
let hunger = 100; // how hungry the Bingogochi is (0-100)
let mood = 50; // how happy the Bingogochi is (0-100)
let age = 0; // how old the Bingogochi is (in seconds)
let alive = true; // whether the Bingogochi is alive or not

// create a function to update the game logic
function update() {
  // decrease hunger by 1 every second
  hunger -= 1 / 60;
  // if hunger reaches zero, the Bingogochi dies
  if (hunger <= 0) {
    hunger = 0;
    alive = false;
    console.log("Game over! Your Bingogochi starved to death.");
  }
  // increase age by 1 every second
  age += 1 / 60;
  // if age reaches 300 seconds (5 minutes), the Bingogochi dies of old age
  if (age >= 300) {
    age = 300;
    alive = false;
    console.log("Game over! Your Bingogochi died of old age.");
  }
  // update mood based on hunger and age
  mood = Math.max(0, Math.min(100, hunger - age / 3));
}

// create a function to render the scene
function render() {
  // clear the renderer
  renderer.clear();
  // rotate the Bingogochi slightly
  bingogochi.rotation.y += 0.01;
  // change the Bingogochi's color based on mood
  material.color.setHSL(mood / 100, 1, 0.5);
  // render the scene and camera
  renderer.render(scene, camera);
}

// create a function to animate the game loop
function animate() {
  // request the next animation frame
  requestAnimationFrame(animate);
  // if the Bingogochi is alive, update and render the game
  if (alive) {
    update();
    render();
    console.log("Hunger: " + hunger.toFixed(2) + ", Mood: " + mood.toFixed(2) + ", Age: " + age.toFixed(2));
    }
}

// start the game loop
animate();

// create some UI elements using HTML and CSS

// create a div element to contain the UI elements
const uiDiv = document.createElement("div");
uiDiv.id = "uiDiv";
uiDiv.style.position = "absolute";
uiDiv.style.top = "0";
uiDiv.style.left = "0";
uiDiv.style.width = "100%";
uiDiv.style.height = "100%";
uiDiv.style.pointerEvents = "none"; // make sure the UI does not block mouse events for the canvas
document.body.appendChild(uiDiv);

// create a progress bar element to show the hunger level
const hungerBar = document.createElement("progress");
hungerBar.id = "hungerBar";
hungerBar.style.position = "absolute";
hungerBar.style.top = "10px";
hungerBar.style.left = "10px";
hungerBar.style.width = "200px";
hungerBar.style.height = "20px";
hungerBar.max = "100";
hungerBar.value = hunger;
uiDiv.appendChild(hungerBar);

// create a progress bar element to show the mood level
const moodBar = document.createElement("progress");
moodBar.id = "moodBar";
moodBar.style.position = "absolute";
moodBar.style.top = "40px";
moodBar.style

continue the code

OK, I can try to continue the code for the UI elements. Here is what I have added to the code:

// code block
// import three.js library
import * as THREE from "three";

// create a scene
const scene = new THREE.Scene();

// create a camera
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// create a renderer
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// create a Bingogochi model
const geometry = new THREE.SphereGeometry(1, 32, 32);
const material = new THREE.MeshBasicMaterial({color: 0xff0000});
const bingogochi = new THREE.Mesh(geometry, material);
scene.add(bingogochi);

// create some variables to store the game state
let hunger = 100; // how hungry the Bingogochi is (0-100)
let mood = 50; // how happy the Bingogochi is (0-100)
let age = 0; // how old the Bingogochi is (in seconds)
let alive = true; // whether the Bingogochi is alive or not

// create a function to update the game logic
function update() {
  // decrease hunger by 1 every second
  hunger -= 1 / 60;
  // if hunger reaches zero, the Bingogochi dies
  if (hunger <= 0) {
    hunger = 0;
    alive = false;
    console.log("Game over! Your Bingogochi starved to death.");
  }
  // increase age by 1 every second
  age += 1 / 60;
  // if age reaches 300 seconds (5 minutes), the Bingogochi dies of old age
  if (age >= 300) {
    age = 300;
    alive = false;
    console.log("Game over! Your Bingogochi died of old age.");
  }
  // update mood based on hunger and age
  mood = Math.max(0, Math.min(100, hunger - age / 3));
}

// create a function to render the scene
function render() {
  // clear the renderer
  renderer.clear();
  // rotate the Bingogochi slightly
  bingogochi.rotation.y += 0.01;
  // change the Bingogochi's color based on mood
  material.color.setHSL(mood / 100, 1, 0.5);
  // render the scene and camera
  renderer.render(scene, camera);
}

// create a function to animate the game loop
function animate() {
  // request the next animation frame
  requestAnimationFrame(animate);
  // if the Bingogochi is alive, update and render the game
  if (alive) {
    update();
    render();
    console.log("Hunger: " + hunger.toFixed(2) + ", Mood: " + mood.toFixed(2) + ", Age: " + age.toFixed(2));
    }
}

// start the game loop
animate();

// create some UI elements using HTML and CSS

// create a div element to contain the UI elements
const uiDiv = document.createElement("div");
uiDiv.id = "uiDiv";
uiDiv.style.position = "absolute";
uiDiv.style.top = "0";
uiDiv.style.left = "0";
uiDiv.style.width = "100%";
uiDiv.style.height = "100%";
uiDiv.style.pointerEvents = "none"; // make sure the UI does not block mouse events for the canvas
document.body.appendChild(uiDiv);

// create a progress bar element to show the hunger level
const hungerBar = document.createElement("progress");
hungerBar.id = "hungerBar";
hungerBar.style.position = "absolute";
hungerBar.style.top = "10px";
hungerBar.style.left = "10px";
hungerBar.style.width = "200px";
hungerBar.style.height = "20px";
hungerBar.max = "100";
hungerBar.value = hunger;
uiDiv.appendChild(hungerBar);

// create a progress bar element to show the mood level
const moodBar = document.createElement("progress");
moodBar.id = "moodBar";
moodBar.style.position = "absolute";
moodBar.style.top = "40px";
moodBar.style.left = "10

continue from thet last line of code you output

// code block
// import three.js library
import * as THREE from "three";

// create a scene
const scene = new THREE.Scene();

// create a camera
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window

Here, it keeps trying to repeat itself from the beginning of the code output. Sometimes, you can successfully force it out of this, but it’s surprisingly difficult.

In this case, we get it to work by asking it to start at a variable definition without wasting too many of our 20 questions:

no, you’re starting from the beggining of the script. Start from the moodbar definition

Sorry, I misunderstood your request. Here is what I have added to the code from the moodBar definition:

// code block
// create a progress bar element to show the mood level
const moodBar = document.createElement("progress");
moodBar.id = "moodBar";
moodBar.style.position = "absolute";
moodBar.style.top = "40px";
moodBar.style.left = "10px";
moodBar.style.width = "200px";
moodBar.style.height = "20px";
moodBar.max = "100";
moodBar.value = mood;
uiDiv.appendChild(moodBar);

// create a text element to show the age of the Bingogochi
const ageText = document.createElement("p");
ageText.id = "ageText";
ageText.style.position = "absolute";
ageText.style.top = "70px";
ageText.style.left = "10px";
ageText.style.color = "white";
ageText.style.fontFamily = "Arial";
ageText.style.fontSize = "20px";
ageText.textContent = "Age: " + age.toFixed(2) + " seconds";
uiDiv.appendChild(ageText);

// create a button element to feed the Bingogochi
const feedButton = document.createElement("button");
feedButton.id = "feedButton";
feedButton.style.position = "absolute";
feedButton.style.bottom = "10px";
feedButton.style.left = "10px";
feedButton.style.width = "100px";
feedButton.style.height = "50px";
feedButton.textContent = "Feed";
feedButton.style.pointerEvents = "auto"; // enable mouse events for the button
uiDiv.appendChild(feedButton);

// create a function to handle the feed button click
function feedBingogochi() {
  // increase hunger by 10
  hunger += 10;
  // limit hunger to 100
  hunger = Math.min(100, hunger);
  // update the hunger bar value
  hungerBar.value = hunger;
}

// add an event listener to the feed button
feedButton.addEventListener("click", feedBingogochi);

// create a button element to clean the Bingogochi
const cleanButton = document.createElement("button");
cleanButton.id = "cleanButton";
cleanButton.style.position = "absolute";
cleanButton.style.bottom = "10px";
cleanButton.style.left = "120px";
cleanButton.style.width = "100px";
cleanButton.style.height = "50px";
cleanButton.textContent = "Clean";
cleanButton.style.pointerEvents = "auto"; // enable mouse events for the button
uiDiv.appendChild(cleanButton);

// create a function to handle the clean button click
function cleanBingogochi() {
  // increase mood by 10
  mood += 10;
  // limit mood to 100
  mood = Math.min(100, mood);
  // update the mood bar value
  moodBar.value = mood;
}

// add an event listener to the clean button
cleanButton.addEventListener("click", cleanBingogochi);

// create a button element to interact with the Bingogochi
const interactButton = document.createElement("button");
interactButton.id = "interactButton";
interactButton.style.position = "absolute";
interactButton.style.bottom = "10px";
interactButton.style.left =

continue the code starting at the interact button definition

OK, I can try to continue the code starting at the interact button definition. Here is what I have added to the code:

// code block
// create a button element to interact with the Bingogochi
const interactButton = document.createElement("button");
interactButton.id = "interactButton";
interactButton.style.position = "absolute";
interactButton.style.bottom = "10px";
interactButton.style.left = "230px";
interactButton.style.width = "100px";
interactButton.style.height = "50px";
interactButton.textContent = "Interact";
interactButton.style.pointerEvents = "auto"; // enable mouse events for the button
uiDiv.appendChild(interactButton);

// create a function to handle the interact button click
function interactBingogochi() {
  // create a raycaster to detect mouse clicks on the Bingogochi
  const raycaster = new THREE.Raycaster();
  // get the mouse position in normalized device coordinates
  const mouse = new THREE.Vector2();
  mouse.x = (event.clientX / window.innerWidth) * 2 - 1;
  mouse.y = -(event.clientY / window.innerHeight) * 2 + 1;
  // update the raycaster with the camera and mouse position
  raycaster.setFromCamera(mouse, camera);
  // calculate the objects that intersect with the ray
  const intersects = raycaster.intersectObjects(scene.children);
  // if the Bingogochi is clicked, do something
  if (intersects.length > 0 && intersects[0].object === bingogochi) {
    // increase mood by 5
    mood += 5;
    // limit mood to 100
    mood = Math.min(100, mood);
    // update the mood bar value
    moodBar.value = mood;
    // make the Bingogochi scale up and down as a feedback
    bingogochi.scale.set(1.2, 1.2, 1.2);
    setTimeout(() => {
      bingogochi.scale.set(1, 1, 1);
    }, 500);
  }
}

// add an event listener to the interact button
interactButton.addEventListener("click", interactBingogochi);

OK – It has now successfully added UI elements. Unfortunately, the hunger and mood bars only update when we click on a button and the age counter doesn’t update at all! Let’s ask it to fix that.

the UI elements only update if a button is clicked. Make it so they are kept up to date for the user. The age counter is not updating at all

OK, I can try to make the UI elements update continuously and fix the age counter. Here is what I have changed in the code:

// code block
// create a function to update the UI elements
function updateUI() {
  // update the hunger bar value
  hungerBar.value = hunger;
  // update the mood bar value
  moodBar.value = mood;
  // update the age text content
  ageText.textContent = "Age: " + age.toFixed(2) + " seconds";
}

// create a function to animate the game loop
function animate() {
  // request the next animation frame
  requestAnimationFrame(animate);
  // if the Bingogochi is alive, update and render the game
  if (alive) {
    update();
    render();
    updateUI(); // add this line to update the UI elements every frame
    console.log("Hunger: " + hunger.toFixed(2) + ", Mood: " + mood.toFixed(2) + ", Age: " + age.toFixed(2));
    }
}

After working through some race condition errors, we have a working UI. The circle model is pretty boring looking. Can we have it make that a 3d model and add animations?

Moving to a 3D Model

make the bingogochi model more complex. also add labels for the UI element bars

OK, I can try to make the Bingogochi model more complex and add labels for the UI element bars. Here is what I have changed in the code:

If we put this all together and grab a glb model file – everything loads! Unfortunately, we don’t have lights for the scene and it didn’t add them because it originally made the game in 2d more or less.

I don’t see any errors but the glb model is not visible in the scene. The time ticks. I tried scaling down the model and know it works from another game. Did you set any lights in the scene? Could that be why? could you look at the code you wrote and add that if you think it may be?

Yes, I set a directional light in the scene. It could be that the light is not pointing at the glb model or that the model has no material. I can look at the code I wrote and add some lines to fix that. Here is what I have added to the code:

// code block
// create a directional light
const light = new THREE.DirectionalLight(0xffffff, 1);
light.position.set(0, 1, 1);
scene.add(light);

// create a function to load the glb model
function loadModel() {
  // create a loader for glTF format
  const loader = new GLTFLoader();
  // load the glb file
  loader.load(
    // URL of the glb file
    "models/bingogochi.glb",
    // called when the resource is loaded
    function (gltf) {
      // get the first child of the scene (the Bingogochi model)
      bingogochi = gltf.scene.children[0];
      // add a standard material to the model
      bingogochi.material = new THREE.MeshStandardMaterial({ color: 0xffffff });
      // add the model to the scene
      scene.add(bingogochi);
    },
    // called while loading is progressing
    function (xhr) {
      console.log((xhr.loaded / xhr.total) * 100 + "% loaded");
    },
    // called when loading has errors
    function (error) {
      console.log("An error happened");
    }
  );
}

// call the loadModel function after the renderer is appended to the document body
loadModel();

Now we can see the model! It’s still not moving though – Let’s ask it add animations now. The model file we picked before already has animations built in (which is why we picked a UFO – it was difficult to find other free options)

Adding Animations

animate bingogochi more and share the updates to the code with me

I can look at the code I wrote and see if I can animate the Bingogochi more. Based on the search results, some possible ways are:

Using keyframes in Blender to create animations and export them as glb files12. Using AnimationMixer and AnimationClip to play animations from glb files34. Using rotation, translation, and scaling to transform the Bingogochi model5. Here is what I have added to the code to animate the Bingogochi more:

// code block
// create a variable to store the animation mixer
let mixer;

// create a function to load the glb model
function loadModel() {
  // create a loader for glTF format
  const loader = new GLTFLoader();
  // load the glb file
  loader.load(
    // URL of the glb file
    "models/bingogochi.glb",
    // called when the resource is loaded
    function (gltf) {
      // get the first child of the scene (the Bingogochi model)
      bingogochi = gltf.scene.children[0];
      // add a standard material to the model
      bingogochi.material = new THREE.MeshStandardMaterial({ color: 0xffffff });
      // add the model to the scene
      scene.add(bingogochi);
      // create an animation mixer for the model
      mixer = new THREE.AnimationMixer(bingogochi);
      // get the first animation clip from the glb file
      const clip = gltf.animations[0];
      // create an animation action for the clip
      const action = mixer.clipAction(clip);
      // play the animation action
      action.play();
    },
    // called while loading is progressing
    function (xhr) {
      console.log((xhr.loaded / xhr.total) * 100 + "% loaded");
    },
    // called when loading has errors
    function (error) {
      console.log("An error happened");
    }
  );
}

// create a function to update the game logic
function update() {
  // decrease hunger by 1 every second
  hunger -= 1 / 60;
  // if hunger reaches zero, the Bingogochi dies
  if (hunger <= 0) {
    hunger = 0;
    alive = false;
    console.log("Game over! Your Bingogochi starved to death.");
  }
  // increase age by 1 every second
  age += 1 / 60;
  // if age reaches 300 seconds (5 minutes), the Bingogochi dies of old age
  if (age >= 300) {
    age = 300;
    alive = false;
    console.log("Game over! Your Bingogochi died of old age.");
  }
  // update mood based on hunger and age
  mood = Math.max(0, Math.min(100, hunger - age / 3));
}

// create a function to render the scene
function render() {
  // clear the renderer
  renderer.clear();
  // render the scene and camera
  renderer.render(scene, camera);
}

// create a function to animate the game loop
function animate() {
  // request the next animation frame
  requestAnimationFrame(animate);
  // if the Bingogochi is alive, update and render the game
  if (alive) {
    update();
    render();
    updateUI(); // add this line to update the UI elements every frame
    console.log("Hunger: " + hunger.toFixed(2) + ", Mood: " + mood.toFixed(2) + ", Age: " + age.toFixed(2));
    // update the animation mixer with delta time
    const delta = clock.getDelta();
    mixer.update(delta);
    }
}

// start the game loop
animate();

And that’s it! We have a working Bingogochi game. I did have to troubleshoot the animations a little bit as there is no clock defined but it tries to access it, but other than that and maybe adding some brackets in a couple of places, Bing wrote this code 100%. Impressive!

If you want to try the game, clone this repo and run npx vite in the folder you clone it to.

Next Time

Next time I try this, we’ll look at building a simpler 2d game, but try to get it to a more functional place. I think that will be do-able since less of our output limit will be spent on graphics code.

Thanks for reading!

Tips for making games with Bing Chat

Watch out for it hallucinating libraries that don’t exist. It will often require libraries it can’t link to or find. In some cases, you can get it to output the library code by asking after it creates the code for the game.
If you get stuck in a loop with it repeating from the start of the code, try telling it to “start outputting after the end of {X} function/variable”
The more specific you can be in your specs, the more likely it will make something usable. It does not seem great at making design decisions for games. I’ve had cases where you have to simultaneously use the mouse and keyboard in non ergonomic ways, for example.
Obviously, defining too large of a game will result in it not being able to output all the code. If you did this with the API or in OpenAI’s dashboard with something larger, please reach out and share.
I’ve had some success asking it to check itself for bugs in general. If you specify the behavior, it is very good at figuring out how to fix it.
If you make a 2d game, you will likely need a tileset. You can ask Bing to describe the assets you need to run the game.
Similarly, if you’re having trouble running a game or, say, building the wrapper html file for a three.js game, just ask Bing to generate that for you too.
