Detailed Description

Abstract base class for the different types of joints.

All joints are used to connect two dynamic actors, or an actor and the environment.

Definition at line 36 of file physxJoint.h.


Member Function Documentation

void PhysxJoint::add_limit_plane ( const LVector3f normal,
const LPoint3f pointInPlane,
float  restitution = 0.0f 
)

Adds a limit plane.

The parameters are given in global coordinates. The plane is affixed to the actor that does not have the limit point.

The normal of the plane points toward the positive side of the plane, and thus toward the limit point. If the normal points away from the limit point at the time of this call, the method returns false and the limit plane is ignored.

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void PhysxJoint::purge_limit_planes ( )

Deletes all limit planes added to the joint.

Definition at line 343 of file physxJoint.cxx.

void ReferenceCount::ref ( ) const [inline, inherited]

Explicitly increments the reference count.

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

void PhysxJoint::set_breakable ( float  maxForce,
float  maxTorque 
)

Sets the maximum force magnitude that the joint is able to withstand without breaking.

If the joint force rises above this threshold, the joint breaks, and becomes disabled.

There are two values, one for linear forces, and one for angular forces. Both values are used directly as a value for the maximum impulse tolerated by the joint constraints.

Both force values are NX_MAX_REAL by default. This setting makes the joint unbreakable. The values should always be nonnegative.

The distinction between maxForce and maxTorque is dependent on how the joint is implemented internally, which may not be obvious. For example what appears to be an angular degree of freedom may be constrained indirectly by a linear constraint.

So in most practical applications the user should set both maxTorque and maxForce to low values.

void PhysxJoint::set_global_anchor ( const LPoint3f anchor)

void PhysxJoint::set_global_axis ( const LVector3f axis)

void PhysxJoint::set_limit_point ( const LPoint3f pos,
bool  isOnActor2 = true 
)

Sets the limit point.

The point is specified in the global coordinate frame.

All types of joints may be limited with the same system: You may elect a point attached to one of the two actors to act as the limit point. You may also specify several planes attached to the other actor.

The points and planes move together with the actor they are attached to.

The simulation then makes certain that the pair of actors only move relative to each other so that the limit point stays on the positive side of all limit planes.

The default limit point is (0,0,0) in the local frame of actor2. Calling this deletes all existing limit planes

The name can be retrieved again with get_name(). This is for debugging and is not used by the physics engine.

bool ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]
bool ReferenceCount::test_ref_count_nonzero ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't zero, or completely bogus.

Returns true if ok, false otherwise.

bool ReferenceCount::unref ( ) const [inline, virtual, inherited]

Explicitly decrements the reference count.

Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is true if the new reference count is nonzero, false if it is zero.
