Collision detection

Okay kiddo, so let's say you're playing with your toys and you want to know if two of them bumped into each other. That's kind of like what we call collision detection!

To make sure that the toys touched, we need to figure out if they both occupy the same space. Imagine that each toy has a special bubble around it, like a force field, and if those bubbles touch, then the toys have collided.

In the same way, when we're playing a video game, the computer needs to check if any of the things in the game have bumped into each other. It does this by checking their positions and sizes, just like the bubbles around your toys.

The computer checks where each object is on the screen, and then it looks at the size of each object to see if they're overlapping. If they are, then the computer knows that they collided.

This is important in video games because it tells the computer what should happen next - like if a character got hit by a bullet or if a ball bounced off a wall.

So, collision detection is basically like making sure your toys don't bump into each other and making sure the video game characters don't bump into each other too. It's like making sure everything stays in its own space!
