Detailed Description
Base class for simulated objects in bullet.
This provides a pretty generic interface since different types of objects are handled very differently, e.g. regular rigid bodies vs. characters.

Member Function Documentation
| virtual void Sirikata::BulletObject::applyForcedLocation | ( | const TimedMotionVector3f & | loc, |
| uint64 | epoch | ||
| ) | [pure virtual] |
Apply the given position to this object.
This takes whatever steps are necessary to apply the change, even completely reloading the object in Bullet. This should only be used when absolutely necessary, e.g. for updates about remote, physically simulated objects.
Implemented in Sirikata::BulletCharacterObject, and Sirikata::BulletRigidBodyObject.
| virtual void Sirikata::BulletObject::applyForcedOrientation | ( | const TimedMotionQuaternion & | orient, |
| uint64 | epoch | ||
| ) | [pure virtual] |
Apply the given orientation to this object.
This takes whatever steps are necessary to apply the change, even completely reloading the object in Bullet. This should only be used when absolutely necessary, e.g. for updates about remote, physically simulated objects.
Implemented in Sirikata::BulletCharacterObject, and Sirikata::BulletRigidBodyObject.
| virtual bool Sirikata::BulletObject::applyRequestedLocation | ( | const TimedMotionVector3f & | loc, |
| uint64 | epoch | ||
| ) | [pure virtual] |
Try to apply the requested position to this object, updating the physics simulation if necessary.
Some types of objects may always fail to apply updates. Returns true if the update was applied and an update will need to be sent.
Implemented in Sirikata::BulletCharacterObject, and Sirikata::BulletRigidBodyObject.
| virtual bool Sirikata::BulletObject::applyRequestedOrientation | ( | const TimedMotionQuaternion & | orient, |
| uint64 | epoch | ||
| ) | [pure virtual] |
Try to apply the requested orientation to this object, updating the physics simulation if necessary.
Some types of objects may always fail to apply updates. Returns true if the update was applied and an update will need to be sent.
Implemented in Sirikata::BulletCharacterObject, and Sirikata::BulletRigidBodyObject.
| virtual bulletObjBBox Sirikata::BulletObject::bbox | ( | ) | [pure virtual] |
Implemented in Sirikata::BulletCharacterObject, and Sirikata::BulletRigidBodyObject.

| virtual void Sirikata::BulletObject::internalTick | ( | const Time & | t | ) | [inline, virtual] |
Make modifications during an internal tick.
Useful for capping speed and rotational speed.

| virtual void Sirikata::BulletObject::load | ( | Mesh::MeshdataPtr | mesh | ) | [pure virtual] |

This should setup any Bullet state and start the physical simulation on the object.
