Detailed Description

Implementation of BulletObject for characters.

Characters behave differently than other physical objects -- they try to stay on the ground and fall like normal objects, but we don't want them to rotate, want them to slide against the ground and walls, etc.

Member Function Documentation

void Sirikata::BulletCharacterObject::applyForcedLocation ( const TimedMotionVector3f &  loc,
uint64  epoch 
) [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.

Implements Sirikata::BulletObject.

References Sirikata::BulletPhysicsService::currentPosition(), Sirikata::BulletPhysicsService::info(), mGhostObject, mID, Sirikata::BulletObject::mParent, Sirikata::LocationInfo::props, and Sirikata::SequencedPresenceProperties::setLocation().

void Sirikata::BulletCharacterObject::applyForcedOrientation ( const TimedMotionQuaternion &  orient,
uint64  epoch 
) [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.

Implements Sirikata::BulletObject.

References Sirikata::BulletPhysicsService::currentOrientation(), Sirikata::BulletPhysicsService::info(), mGhostObject, mID, Sirikata::BulletObject::mParent, Sirikata::LocationInfo::props, Sirikata::SequencedPresenceProperties::setOrientation(), Sirikata::Vector4< scalar >::w, Sirikata::Vector4< scalar >::x, Sirikata::Vector4< scalar >::y, and Sirikata::Vector4< scalar >::z.

Referenced by applyRequestedOrientation().

bool Sirikata::BulletCharacterObject::applyRequestedLocation ( const TimedMotionVector3f &  loc,
uint64  epoch 
) [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.

Implements Sirikata::BulletObject.

References applyForcedLocation().

bool Sirikata::BulletCharacterObject::applyRequestedOrientation ( const TimedMotionQuaternion &  orient,
uint64  epoch 
) [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.

Implements Sirikata::BulletObject.

References applyForcedOrientation().

bulletObjBBox Sirikata::BulletCharacterObject::bbox ( ) [virtual]

Implements Sirikata::BulletObject.

References mBBox.

void Sirikata::BulletCharacterObject::deactivationTick ( const Time &  t) [virtual]

Check this object for deactivation.

Implementations should call BulletPhysicsService::updateObjectFromDeactivation if the object has been deactivated.

Reimplemented from Sirikata::BulletObject.

References mGhostObject, mID, Sirikata::BulletObject::mParent, and Sirikata::BulletPhysicsService::updateObjectFromDeactivation().

bool Sirikata::BulletCharacterObject::fixed ( ) [virtual]

Implements Sirikata::BulletObject.

void Sirikata::BulletCharacterObject::load ( Mesh::MeshdataPtr  mesh) [virtual]

After the mesh has been downloaded and parsed (or immediately if no mesh is required), this loads the object into the simulation.

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

Implements Sirikata::BulletObject.

float32 Sirikata::BulletCharacterObject::mass ( ) [virtual]

Implements Sirikata::BulletObject.

void Sirikata::BulletCharacterObject::postTick ( const Time &  t) [virtual]

Make modifications before a full tick.

Make modifications before a full tick.
