Math.raycast

Available since: Gideros 2020.9
Class: math

Description

Returns collisions between a ray and a shape.

(table) = math.raycast(origin,direction,shape)

Shapes are tables which can have the following forms:

• { x, y, z, radius }: Represent a sphere (3D) or a circle (2D)
• { x, y, z, normal }: Represent a plane (3D) or a line (2D)
• { x, y, z, normal, extent }: Represent a disk (3D) or a segment (2D)
• { x, y, x2, y2 }: Represent a segment (2D)
• { x, y, z, 1, 2, ... }: Represent a shape group

Each resulting collison contains the following fields: - point: collision point - distance: distance of the collision point from the origin - normal: normal vector of the shape surface at the collision point - reflect: reflection direction

Parameters

origin: (table) The origin of the ray
direction: (table) The direction of the ray
shape: (table) The shape to test against

Return values

Returns (table) A list of intersections
