JavaScript Game Development: Create Your Own Breakout Game

Set up a breakout game project with an html boilerplate, a css reset, and a canvas, then draw a red rectangle using the 2d context.

Develop practice drawing shapes on the canvas by using beginPath, arc, fill, and stroke to render a green circle and a semi-transparent rectangle, preparing for movement in the breakout game.

Learn canvas coordinate system with a top-left origin, move the ball by updating x and y with the plus equals operator, and clear the canvas every frame to remove trails.

implement collision detection to bounce a ball off all four canvas edges, using a ball radius and velocity components to reverse direction when hitting boundaries.

Update the collision detection to bounce at the ball's edge, not the center. Subtract the ball radius from height and width checks to stop sinking into walls on both axes.

Draw a paddle on a canvas and move it with left/right arrows, using keydown and keyup to keep it within the game boundaries.

Set up a 3x5 brick field for the breakout game, defining brick size, padding, and offsets, storing bricks in a two-dimensional array and drawing them on the canvas.

Explore brick collision detection for a breakout game by checking the ball center against bricks, bouncing the ball, and deactivating bricks with a status flag for redraw and score.

Track and display the score on the canvas as bricks disappear when the ball hits them, updating the score each frame and declaring a win when all bricks are gone.

Introduce a mouse move listener to control the paddle, compute relative x, center the paddle on the cursor, and keep it within the canvas boundaries.

Set up three player lives and render them on the canvas beside the score. Subtract a life when the ball hits the bottom, using requestAnimationFrame for smooth rendering.
