Member Function Documentation

CollideMask BulletBodyNode::get_legal_collide_mask ( ) const [virtual]

Returns the subset of CollideMask bits that may be set for this particular type of PandaNode.

For BodyNodes this returns all bits on.

Reimplemented from PandaNode.

Definition at line 50 of file bulletBodyNode.cxx.

References BitMask< WType, nbits >::all_on().

bool BulletBodyNode::is_debug_enabled ( ) const [inline]

Returns TRUE if the debug visualisation is enabled for this collision object, and FALSE if the debug visualisation is disabled.

Definition at line 275 of file bulletBodyNode.I.

void BulletBodyNode::output ( ostream &  out) const [virtual]

Outputs the Namable.

This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

Reimplemented from PandaNode.

Reimplemented in BulletRigidBodyNode.

Definition at line 152 of file bulletBodyNode.cxx.

bool BulletBodyNode::safe_to_combine ( ) const [virtual]

Returns true if it is generally safe to combine this particular kind of PandaNode with other kinds of PandaNodes of compatible type, adding children or whatever.

For instance, an LODNode should not be combined with any other PandaNode, because its set of children is meaningful.

Reimplemented from PandaNode.

Definition at line 113 of file bulletBodyNode.cxx.

bool BulletBodyNode::safe_to_combine_children ( ) const [virtual]

Returns true if it is generally safe to combine the children of this PandaNode with each other.

For instance, an LODNode's children should not be combined with each other, because the set of children is meaningful.

Reimplemented from PandaNode.

Definition at line 128 of file bulletBodyNode.cxx.

bool BulletBodyNode::safe_to_flatten ( ) const [virtual]

Returns true if it is generally safe to flatten out this particular kind of Node by duplicating instances, false otherwise (for instance, a Camera cannot be safely flattened, because the Camera pointer itself is meaningful).

Reimplemented from PandaNode.

Definition at line 65 of file bulletBodyNode.cxx.

bool BulletBodyNode::safe_to_flatten_below ( ) const [virtual]

Returns true if a flatten operation may safely continue past this node, or false if nodes below this node may not be molested.

Reimplemented from PandaNode.

Definition at line 141 of file bulletBodyNode.cxx.

bool BulletBodyNode::safe_to_modify_transform ( ) const [virtual]

Returns true if it is safe to automatically adjust the transform on this kind of node.

Usually, this is only a bad idea if the user expects to find a particular transform on the node.

ModelNodes with the preserve_transform flag set are presently the only kinds of nodes that should not have their transform even adjusted.

Reimplemented from PandaNode.

Definition at line 97 of file bulletBodyNode.cxx.

bool BulletBodyNode::safe_to_transform ( ) const [virtual]

Returns true if it is generally safe to transform this particular kind of Node by calling the xform() method, false otherwise.

For instance, it's usually a bad idea to attempt to xform a Character.

Reimplemented from PandaNode.

Definition at line 79 of file bulletBodyNode.cxx.

void BulletBodyNode::set_contact_processing_threshold ( PN_stdfloat  threshold)

The constraint solver can discard solving contacts, if the distance is above this threshold.

Definition at line 529 of file bulletBodyNode.cxx.

void BulletBodyNode::set_debug_enabled ( const bool  enabled) [inline]

Enables or disables the debug visualisation for this collision object.

By default the debug visualisation is enabled.

Definition at line 262 of file bulletBodyNode.I.

void BulletBodyNode::set_into_collide_mask ( CollideMask  mask) [inline]

Sets the "into" CollideMask.

This specifies the set of bits that must be shared with a CollisionNode's "from" CollideMask in order for the CollisionNode to detect a collision with this particular node.

The actual CollideMask that will be set is masked by the return value from get_legal_collide_mask(). Thus, the into_collide_mask cannot be set to anything other than nonzero except for those types of nodes that can be collided into, such as CollisionNodes and GeomNodes.

Reimplemented from PandaNode.
