Example: How to add simple Hit Detection to your game in PixiJS

This example initializes a PixiJS application, configuring its canvas size to match the dimensions of the browser window. When the user clicks anywhere on the canvas, the addMoreSprites() function is triggered, adding 10 new sprites to the stage. Each sprite is represented by an image (hexagon.png) and is randomly positioned within the canvas area. These sprites move across the canvas at varying velocities, bouncing off the edges when they reach them.

The application continuously animates the sprites using the app.ticker.add() method, updating their positions based on their velocities. Additionally, it performs a hit test between all pairs of sprites to detect collisions. If two sprites come within a certain distance of each other, worked out by the calculateDistanceBetweenTwoPoints() function, their tint colors are changed to indicate a collision.

This example tries to demonstrate the creation of an interactive PixiJS application with sprite animation and collision detection.
