3D Physics and Collision
Since v2.3.0, Cocos Creator has added support for 3D Physics and Collision.
Cocos Creator’s physics engine is based on
cannon.js and provides users with an efficient, componentized workflow with convenient usage methods. Currently, supported functionality is: rigid body, Box/Sphere collision components, trigger and collision events, physical materials, ray detection and many other features.
Builtin, the 3D collision detection system, is a physics module with only a collision detection system. It does not have complicated physics simulation calculations, which will make the game’s package smaller and provide better performance.
The 3D Physics and Collision includes the following:
- Setting Physics Engine
- Physics Manager
- RigidBody Component Reference
- ConstantForce Component Reference
- Collider Component Reference
- Physics Events
- Physics Material
The group management of 3D Physics and Collision is completely the same as 2D, please refer to Collision Group Management for details.
