Since we're working on showing the bird as a visual game element, we need to first create the bird object. Let's start by creating a new JavaScript object that we'll use to represent our bird.\n\nHere's the code:\n\n```javascript\nlet bird;\n\nfunction setup() {\n createCanvas(400, 600);\n bird = new Bird();\n background(220);\n}\n\nfunction Bird() {\n this.y = height/2;\n this.x = 64;\n\n this.show = function() {\n fill(255);\n ellipse(this.x, this.y, 32, 32);\n }\n}\n```\n\nWhat we did here:\n\n- We first declare a `bird` variable at the top of our program. This variable will hold our bird object.\n- In the `setup` function, we initialize our bird object by calling `new Bird()`. This creates a new instance of our Bird object and assigns it to our `bird` variable.\n- We then define a Bird function that creates an object with `x` and `y` properties (representing the bird's position on the screen) and a `show` method. The `show` method uses p5's `fill` and `ellipse` functions to draw a circle at the bird's position. This circle will represent our bird in the game.","created_at":"2023-12-28T20:32:43.175524Z","output_tokens":null},{"deleted":0,"code_id":11075,"input_tokens":null,"id":6919,"project_id":182,"sender":"human","message":"why use a function for the bird?","created_at":"2023-12-28T20:33:25.809109Z","output_tokens":null},{"deleted":0,"code_id":11075,"input_tokens":null,"id":6920,"project_id":182,"sender":"ai","message":"We're using a function for the bird because in JavaScript, functions can be used to create objects.

This will make the bird fall down.\n- We're also checking if the bird has hit the ground or the top of the screen. If it has, we're setting its y-position to the boundary and its velocity to zero.\n- In the `draw` function, we're updating the bird's position and redrawing it every frame. This will animate our bird falling due to gravity.","created_at":"2023-12-28T20:33:51.688321Z","output_tokens":null},{"deleted":0,"code_id":11084,"input_tokens":null,"id":6929,"project_id":182,"sender":"human","message":"okay cool, and now let's make it so when I click or hit space bar, the bird goes up ","created_at":"2023-12-28T20:34:38.823573Z","output_tokens":null},{"deleted":0,"code_id":11084,"input_tokens":null,"id":6930,"project_id":182,"sender":"ai","message":"Sure, let's add that functionality.

We've also added an `up` method that adds this lift to the bird's velocity.\n- In the `update` method, we're also multiplying the velocity by 0.9 each frame. This is to simulate air resistance and make the bird's flight look more natural.\n- We've added two new functions, `mousePressed` and `keyPressed`, which p5.js will automatically call whenever the mouse is clicked or a key is pressed, respectively. In these functions, we're calling the bird's `up` method to make it fly upwards.","created_at":"2023-12-28T20:34:38.829457Z","output_tokens":null},{"deleted":0,"code_id":11097,"input_tokens":null,"id":6933,"project_id":182,"sender":"human","message":"okay now let's add pipes that pass by","created_at":"2023-12-28T20:35:42.786443Z","output_tokens":null},{"deleted":0,"code_id":11097,"input_tokens":null,"id":6934,"project_id":182,"sender":"ai","message":"Sure, let's add pipes to the game!

Each pipe has a `top` and a `bottom` (which are random lengths), an `x` position, a `w` width, and a `speed`.
