panda3d.core.CollisionSolid¶

from panda3d.core import CollisionSolid

class CollisionSolid¶

Bases: CopyOnWriteObject

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.

Inheritance diagram

getCollisionOrigin() → LPoint3¶

Return type: LPoint3

setTangible(tangible: bool) → None¶: 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.

isTangible() → bool¶: Returns whether the solid is considered ‘tangible’ or not. An intangible solid has no effect in a CollisionHandlerPusher (except to throw an event); it’s useful for defining ‘trigger’ planes and spheres, that cause an effect when passed through.

setEffectiveNormal(effective_normal: LVector3) → None¶: 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.

clearEffectiveNormal() → None¶: Removes the normal previously set by setEffectiveNormal().

hasEffectiveNormal() → bool¶: Returns true if a special normal was set by setEffectiveNormal(), false otherwise.

getEffectiveNormal() → LVector3¶

Returns the normal that was set by setEffectiveNormal(). It is an error to call this unless hasEffectiveNormal() returns true.

Return type: LVector3

setRespectEffectiveNormal(respect_effective_normal: bool) → None¶: 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.

getRespectEffectiveNormal() → bool¶: See setRespectEffectiveNormal().

getBounds() → BoundingVolume¶

Returns the solid’s bounding volume.

Return type: BoundingVolume

setBounds(bounding_volume: BoundingVolume) → None¶: Returns the solid’s bounding volume.

output(out: ostream) → None¶

write(out: ostream, indent_level: int) → None¶

static getClassType() → TypeHandle¶

Return type: TypeHandle

property collision_origin¶

Return type: LPoint3

property tangible¶

Getter: Returns whether the solid is considered ‘tangible’ or not. An intangible solid has no effect in a CollisionHandlerPusher (except to throw an event); it’s useful for defining ‘trigger’ planes and spheres, that cause an effect when passed through.
Setter: 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.

Return type: bool

property respect_effective_normal¶

Getter: See setRespectEffectiveNormal().
Setter: 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.

Return type: bool

property bounds¶

Getter: Returns the solid’s bounding volume.
Setter: Returns the solid’s bounding volume.

Return type: ConstPointerTo_BoundingVolume
