panda3d.core.CollisionNode¶

class CollisionNode¶

Bases: PandaNode

A node in the scene graph that can hold any number of CollisionSolids. This may either represent a bit of static geometry in the scene that things will collide with, or an animated object twirling around in the world and running into things.

Inheritance diagram

__init__(name: str) → None¶

setCollideMask(mask: CollideMask) → None¶: Simultaneously sets both the “from” and “into” CollideMask values to the same thing.

setFromCollideMask(mask: CollideMask) → None¶: Sets the “from” CollideMask. In order for a collision to be detected from this object into another object, the intersection of this object’s “from” mask and the other object’s “into” mask must be nonzero.

setIntoCollideMask(mask: CollideMask) → None¶: Sets the “into” CollideMask. In order for a collision to be detected from another object into this object, the intersection of the other object’s “from” mask and this object’s “into” mask must be nonzero.

getFromCollideMask() → CollideMask¶

Returns the current “from” CollideMask. In order for a collision to be detected from this object into another object, the intersection of this object’s “from” mask and the other object’s “into” mask must be nonzero.

Return type: CollideMask

getIntoCollideMask() → CollideMask¶

Returns the current “into” CollideMask. In order for a collision to be detected from another object into this object, the intersection of the other object’s “from” mask and this object’s “into” mask must be nonzero.

Return type: CollideMask

clearSolids() → None¶: Removes all solids from the node.

getNumSolids() → size_t¶

Return type: size_t

getSolid(n: size_t) → CollisionSolid¶

Return type: CollisionSolid

modifySolid(n: size_t) → CollisionSolid¶

Return type: CollisionSolid

setSolid(n: size_t, solid: CollisionSolid) → None¶: Replaces the solid with the indicated index.

insertSolid(n: size_t, solid: CollisionSolid) → None¶: Inserts the indicated solid to the node at the indicated position.

removeSolid(n: size_t) → None¶: Removes the solid with the indicated index. This will shift all subsequent indices down by one.

addSolid(solid: CollisionSolid) → size_t¶

Adds the indicated solid to the node. Returns the index of the new solid within the node’s list of solids.

Return type: size_t

getColliderSort() → int¶: Returns the collider_sort value that has been set for this particular node. See setColliderSort().

setColliderSort(sort: int) → None¶

Sets a particular collider_sort value on this node. This controls the order in which colliders (that is, “from nodes”) are grouped together for the collision traversal.

If there are 32 or fewer colliders added to any particular CollisionTraverser, then this value has no meaning. It is only useful if there are many colliders, which may force the CollisionTraverser to make multiple passes through the data; in that case, it may be a useful optimization to group colliders that have similar bounding volumes together (by giving them similar sort values).

static getDefaultCollideMask() → CollideMask¶

Returns the default into_collide_mask assigned to new CollisionNodes.

Return type: CollideMask

static getClassType() → TypeHandle¶

Return type: TypeHandle

getSolids() → list¶

property from_collide_mask¶

Getter: Returns the current “from” CollideMask. In order for a collision to be detected from this object into another object, the intersection of this object’s “from” mask and the other object’s “into” mask must be nonzero.
Setter: Sets the “from” CollideMask. In order for a collision to be detected from this object into another object, the intersection of this object’s “from” mask and the other object’s “into” mask must be nonzero.

Return type: CollideMask

property into_collide_mask¶

Getter: Returns the current “into” CollideMask. In order for a collision to be detected from another object into this object, the intersection of the other object’s “from” mask and this object’s “into” mask must be nonzero.
Setter: Sets the “into” CollideMask. In order for a collision to be detected from another object into this object, the intersection of the other object’s “from” mask and this object’s “into” mask must be nonzero.

Return type: CollideMask

property solids¶

Getter Setter

Replaces the solid with the indicated index.

Return type: Sequence[ConstPointerTo_CollisionSolid]

property collider_sort¶

Getter

Returns the collider_sort value that has been set for this particular node. See setColliderSort().

Setter

Sets a particular collider_sort value on this node. This controls the order in which colliders (that is, “from nodes”) are grouped together for the collision traversal.

If there are 32 or fewer colliders added to any particular CollisionTraverser, then this value has no meaning. It is only useful if there are many colliders, which may force the CollisionTraverser to make multiple passes through the data; in that case, it may be a useful optimization to group colliders that have similar bounding volumes together (by giving them similar sort values).

Return type: int

property default_collide_mask¶

Returns the default into_collide_mask assigned to new CollisionNodes.

Return type: CollideMask
