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.

Inheritance diagram

__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().

__init__(origin: LPoint3, direction: LVector3)

__init__(ox: float, oy: float, oz: float, dx: float, dy: float, dz: float)

property direction → LVector3

static get_class_type() → TypeHandle

get_direction() → LVector3

get_origin() → LPoint3

property origin → LPoint3

Getter Setter

set_direction(direction: LVector3)

set_direction(x: float, y: float, z: float)

set_from_lens(camera: LensNode, point: LPoint2) → bool

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.

set_from_lens(camera: LensNode, px: float, py: float) → bool

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.

set_origin(origin: LPoint3)

set_origin(x: float, y: float, z: float)
