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

To implement physics in a C++ game, you can use libraries like Box2D or Bullet Physics. These libraries provide tools for simulating real-world physics.

What are the key features I should look for in a physics engine?

Key features include collision detection, rigid body dynamics, soft body physics, and support for various shapes and constraints.

Can you give me an example of using Box2D in a simple game?

Sure! In a simple game, you can create a world, define bodies with shapes, and apply forces to simulate movement. Would you like a code snippet?

Yes, please provide a code snippet for a bouncing ball.

Here's a simple example:

b2World world(b2Vec2(0, -10)); // Create a world with gravity

b2BodyDef ballDef;
ballDef.type = b2_dynamicBody;
ballDef.position.Set(0, 10);
b2Body* ball = world.CreateBody(&ballDef);

b2CircleShape circle;
circle.m_radius = 1.0f;
ball->CreateFixture(&circle, 1.0f);

This creates a ball that will bounce under gravity!
