void CollisionHandlerEvent::add_again_pattern | ( | const string & | again_pattern | ) | [inline, inherited] |
Adds the pattern string that indicates how the event names are generated when a collision between two particular nodes is *still* detected.
This event is thrown each consecutive time a collision between two particular nodes is detected, starting with the second time.
In general, the in_pattern event is thrown on the first detection of a collision between two particular nodes. In subsequent passes, as long as a collision between those two nodes continues to be detected each frame, the again_pattern is thrown. The first frame in which the collision is no longer detected, the out_pattern event is thrown.

The indicated DriveInterface will also be updated with the target's new transform each frame. This method should be used when the target is directly controlled by a DriveInterface.

void CollisionHandlerEvent::add_in_pattern | ( | const string & | in_pattern | ) | [inline, inherited] |
Adds a pattern string to the list of events that will be generated in response to a collision.
The pattern string describes how the event name will be composed. It is a string that may contain any of the following:
fn - the name of the "from" object's node in - the name of the "into" object's node fs - 't' if "from" is tangible, 'i' if intangible is - 't' if "into" is tangible, 'i' if intangible ig - 'c' if the collision is into a CollisionNode, 'g' if it is a geom.
%(tag)fh - generate event only if "from" node has the indicated net tag. %(tag)fx - generate event only if "from" node does not have the indicated net tag. %(tag)ih - generate event only if "into" node has the indicated net tag. %(tag)ix - generate event only if "into" node does not have the indicated net tag. %(tag)ft - the indicated net tag value of the "from" node. %(tag)it - the indicated net tag value of the "into" node.
Parentheses in the above are literal and should be included in the actual pattern.
The event name will be based on the in_pattern string specified here, with all occurrences of the above strings replaced with the corresponding values.
In general, the in_pattern event is thrown on the first detection of a collision between two particular nodes. In subsequent passes, as long as a collision between those two nodes continues to be detected each frame, the again_pattern is thrown. The first frame in which the collision is no longer detected, the out_pattern event is thrown.

void CollisionHandlerPhysical::begin_group | ( | ) | [virtual] |

Definition at line 51 of file collisionHandlerPhysical.cxx.
void CollisionHandlerEvent::clear | ( | ) | [inherited] |
Empties the list of elements that all colliders are known to be colliding with.
No "out" events will be thrown; if the same collision is detected next frame, a new "in" event will be thrown for each collision.
This can be called each frame to defeat the persistent "in" event mechanism, which prevents the same "in" event from being thrown repeatedly. However, also see add_again_pattern(), which can be used to set the event that is thrown when a collision is detected for two or more consecutive frames.

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 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 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.
