</a-scene>| Property | Description | Default |
|---|---|---|
| type | static, dynamic or kinematic |
dynamic |
| mass | Mass of body | 1 |
| friction | Friction of body | 0.3 |
| restitution | Bounciness of body | 0.3 |
| belongsTo | Bitmask of groups body belongs to | 1 |
| collidesWith | Bitmask of groups body collides with | 1 |
| emitsWith | Bitmask of groups body emits event when colliding with | 0 |
| sleeping | Whether or not to start sleeping | false |
| autoShape | Automatically add shape components |
true |
If autoShape is true, shape components will be added to all applicable descendants (a-box, a-sphere and a-cylinder).. If the body entity has no child nodes, shape component will be added to the body entity itself..
| Method | Description |
|---|---|
| eval(expression) | Evaluate an expression in the worker, where world and body refer to their native instances. |
| commit() | Commit current position and orientation to the physics world. |
| applyWorldImpulse(force, point) | Apply impulse to the body in world vectors. |
| applyLocalImpulse(force, point) | Apply impulse to the body in local vectors. |
Note: the eval method depends on the specific physics engine that the worker is based on..
