How do I implement physics in a Java game?

To implement physics in a Java game, you can use libraries like JBox2D or create your own physics engine. What specific physics features are you interested in?

I'm interested in collision detection and gravity.

For collision detection, you can use bounding boxes or circles. Gravity can be simulated by applying a constant downward force to your game objects. Would you like code examples for these?

Yes, please provide a simple example for gravity.

Sure! Here's a basic example:

class GameObject {
    float yVelocity = 0;
    final float gravity = 0.98f;

    void update() {
        yVelocity += gravity;
        positionY += yVelocity;
    }
}

This will make your object fall over time. Do you need help with anything else?

What about handling collisions?

For handling collisions, you can check if two objects intersect using their bounding boxes. If they do, you can adjust their positions accordingly. Would you like a code snippet for that?
