static void PhysxCloth::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from PhysxObject.

Definition at line 117 of file physxCloth.h.

References PhysxObject::init_type().

bool PhysxCloth::is_sleeping ( ) const

Returns true if this cloth is sleeping.

When a cloth does not move for a period of time, it is no longer simulated in order to save time. This state is called sleeping. However, because the object automatically wakes up when it is either touched by an awake object, or one of its properties is changed by the user, the entire sleep mechanism should be transparent to the user.

Definition at line 344 of file physxCloth.cxx.

Forces the cloth to sleep.

The cloth will stay asleep until the next call to simulate, and will not wake up until then even when otherwise it would (for example a force is applied to it). It can however wake up during the next do_physics call.

Definition at line 379 of file physxCloth.cxx.

void PhysxCloth::set_external_acceleration ( LVector3f const &  acceleration)

Sets an external acceleration which affects all non attached particles of the cloth.

Definition at line 578 of file physxCloth.cxx.

References LVecBase3f::is_nan(), and PhysxManager::vec3_to_nxVec3().

bool  value 
)

Sets the value of a single flag.

Definition at line 268 of file physxCloth.cxx.

void PhysxCloth::set_group ( unsigned int  group)

Sets which collision group this cloth is part of.

Collision group must be between 0 and 31.

Definition at line 177 of file physxCloth.cxx.

Sets 128-bit mask used for collision filtering.

Definition at line 303 of file physxCloth.cxx.

void PhysxCloth::set_name ( const char *  name)

Sets a name string for the object that can be retrieved with get_name().

This is for debugging and is not used by the engine.

Definition at line 150 of file physxCloth.cxx.

void PhysxCloth::set_sleep_linear_velocity ( float  threshold)

Sets the linear velocity below which an cloth may go to sleep.

Cloths whose linear velocity is above this threshold will not be put to sleep.

Setting the sleep angular/linear velocity only makes sense when the BF_energy_sleep_test is not set.

Definition at line 397 of file physxCloth.cxx.

void PhysxCloth::set_thickness ( float  thickness)

Sets the cloth thickness (must be positive).

Definition at line 203 of file physxCloth.cxx.

void PhysxCloth::set_wind_acceleration ( LVector3f const &  acceleration)

Sets an acceleration acting normal to the cloth surface at each vertex.

Definition at line 593 of file physxCloth.cxx.

References LVecBase3f::is_nan(), and PhysxManager::vec3_to_nxVec3().

void PhysxCloth::wake_up ( float  wakeCounterValue = NX_SLEEP_INTERVAL)

Wakes up the cloth if it is sleeping.

The wakeCounterValue determines how long until the body is put to sleep, a value of zero means that the body is sleeping. wake_up(0) is equivalent to PhysxCloth::put_to_sleep().
