How do I implement a physics engine in my C++ game?

To implement a physics engine in C++, you can start by using libraries like Box2D or Bullet Physics. Do you have a specific feature in mind?

I want to simulate realistic gravity and collisions.

For realistic gravity, you can apply a constant downward force to your objects. For collisions, you'll need to detect when objects intersect and respond accordingly. Would you like code examples?

Yes, please provide a simple example for gravity.

Here's a basic example:

class Object {
public:
    float x, y, velocityY;
    void update() {
        velocityY += gravity; // Apply gravity
        y += velocityY; // Update position
    }
};

This will make your object fall under gravity. Let me know if you need more details!

What about handling collisions?

For collisions, you can use bounding boxes to check for overlaps. If two objects intersect, you can adjust their positions to resolve the collision. Would you like to dive deeper into that?
