The abstract base class for all things that can collide with other things in the world, and all the things they can collide with (except geometry).
This class and its derivatives really work very similarly to the way BoundingVolume and all of its derivatives work. There's a different subclass for each basic shape of solid, and double-dispatch function calls handle the subset of the N*N intersection tests that we care about.

int TypedWritable::complete_pointers | ( | TypedWritable ** | p_list, |
BamReader * | manager | ||
) | [virtual, inherited] |
Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.

bool TypedWritable::decode_raw_from_bam_stream | ( | TypedWritable *& | ptr, |
ReferenceCount *& | ref_ptr, | ||
const string & | data, | ||
BamReader * | reader = NULL |
||
) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.
Returns true on success, false on on error.
This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.
Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.
If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

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 CollisionSolid::mark_internal_bounds_stale | ( | ) | [inline, protected] |
Should be called by a derived class to mark the internal bounding volume stale, so that recompute_internal_bounds() will be called when the bounding volume is next requested.

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.

bool TypedWritable::require_fully_complete | ( | ) | const [virtual, inherited] |
Some objects require all of their nested pointers to have been completed before the objects themselves can be completed.
If this is the case, override this method to return true, and be careful with circular references (which would make the object unreadable from a bam file).
Reimplemented in GeomVertexData, ClipPlaneAttrib, and RenderEffects.

Returns the solid's bounding volume.

void CollisionSolid::set_effective_normal | ( | const LVector3f & | effective_normal | ) | [inline] |
Records a false normal for this CollisionSolid that will be reported by the collision system with all collisions into it, instead of its actual normal.
This is useful as a workaround for the problem of an avatar wanting to stand on a sloping ground; by storing a false normal, the ground appears to be perfectly level, and the avatar does not tend to slide down it.
Definition at line 65 of file collisionSolid.I.
void CollisionSolid::set_respect_effective_normal | ( | bool | respect_effective_normal | ) | [inline] |
This is only meaningful for CollisionSolids that will be added to a traverser as colliders.
It is normally true, but if set false, it means that this particular solid does not care about the "effective" normal of other solids it meets, but rather always uses the true normal.
Definition at line 120 of file collisionSolid.I.
void CollisionSolid::set_tangible | ( | bool | tangible | ) | [inline] |
Sets the current state of the 'tangible' flag.
Set this true to make the solid tangible, so that a CollisionHandlerPusher will not allow another object to intersect it, or false to make it intangible, so that a CollisionHandlerPusher will ignore it except to throw an event.

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.
