from acron.core import CollisionRay

class CollisionRay

Bases:

Bases: CollisionSolid

An infinite ray, with a specific origin and direction. It begins at its origin and continues in one direction to infinity, and it has no radius. Useful for picking from a window, or for gravity effects.

__init__()

Creates an invalid ray. This isn’t terribly useful; it’s expected that the user will subsequently adjust the ray via set_origin()/set_direction() or set_from_lens().

property direction → LVector3

Getter Setter

get_direction()

get_origin()

property origin → LPoint3

Getter Setter

set_direction()

set_from_lens()

Accepts a LensNode and a 2-d point in the range [-1,1]. Sets the CollisionRay so that it begins at the LensNode’s near plane and extends to infinity, making it suitable for picking objects from the screen given a camera and a mouse location.

Accepts a LensNode and a 2-d point in the range [-1,1]. Sets the CollisionRay so that it begins at the LensNode’s near plane and extends to infinity, making it suitable for picking objects from the screen given a camera and a mouse location.

Returns true if the point was acceptable, false otherwise.
