2D Physics and Collision

This section details 2D Physics and Collision. For information about 3D, please refer to 3D Physics and Collision.

The 2D Physics and Collision in Creator consists of two parts:

• Collider component
• Box2D physics engine

For games with few physics calculations, we recommend that users use colliders directly, which avoids loading the physics engine and building the physical world during runtime. The physics engine provides a more complete interface for interactive behaviors and rigidbody, joints, and so on. You can choose your own solution as needed.
