Let's talk about one of the cornerstones of game development - physics and collision detection! This plays a pivotal role in making your game feel responsive and realistic. But don't worry - though the physics can get complex, we'll start simple. 🚀🕹️
Step 1: Setting up the game scene 🎬
Every good game needs a stage, a backdrop if you will. We'll be staging our play on an HTML5 canvas element, a great place for 2D graphics.
let canvas = document.getElementById('game');
let context = canvas.getContext('2d');
This snippet grabs our canvas HTML element by its id, here that's 'game', and sets up the context. Think of the context as our drawing board or canvas where we'll sketch out the game.
Step 2: Creating the game objects 🎲
With our stage ready, we need some actors. For simplicity, let's create a ball that we can bounce around.
let ball = {
x: canvas.width / 2,
y: canvas.height / 2,
radius: 20,
dx: 2,
dy: -2,
color: 'blue'
}
Here, our ball has x and y coordinates initially set to the middle of the canvas. It has a radius of 20 (making it a decently sized ball), moves in both x and y directions (dx and dy) and is of a resplendent blue color.
Stay tuned for our next steps, where we will animate our game and implement collision detection! 🏁
