Data:
| Name | Description | Default value |
|---|---|---|
| name | object name | unnamed |
| printLog | if true, emits extra messages at runtime. | 0 |
| tags | list of the subsets the objet belongs to | |
| bbox | this object bounding box | |
| componentState | The state of the component among (Dirty, Valid, Undefined, Loading, Invalid). | Undefined |
| listening | if true, handle the events, otherwise ignore the events | 0 |
| active | flag indicating if this collision model is active and should be included in default collision detections | 1 |
| moving | flag indicating if this object is changing position between iterations | 1 |
| simulated | flag indicating if this object is controlled by a simulation | 1 |
| selfCollision | flag indication if the object can self collide | 0 |
| proximity | Distance to the actual (visual) surface | 0 |
| contactStiffness | Contact stiffness | 10 |
| contactFriction | Contact friction coefficient (dry or viscous or unused depending on the contact method) | 0 |
| contactRestitution | Contact coefficient of restitution | 0 |
| contactResponse | if set, indicate to the ContactManager that this model should use the given class of contacts. Note that this is only indicative, and in particular if both collision models specify a different class it is up to the manager to choose. | |
| color | color used to display the collision model if requested | 1 0 0 1 |
| group | IDs of the groups containing this model. No collision can occur between collision models included in a common group (e.g. allowing the same object to have multiple collision models) | |
| numberOfContacts | Number of collision models this collision model is currently attached to | 0 |
| bothSide | activate collision on both side of the point model (when surface normals are defined on these points) | 0 |
| computeNormals | activate computation of normal vectors (required for some collision detection algorithms) | 0 |
| displayFreePosition | Display Collision Model Points free position(in green) | 0 |
| leafScale | at which level should the first cube layer be constructed. Note that this must not be greater than GRIDDIM_LOG2 | 0 |
