Declaration

public static RaycastHit2D[] GetRayIntersectionAll(Ray ray, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers);

Parameters

ray The 3D ray defining origin and direction to test.
distance The maximum distance over which to cast the ray.
layerMask The LayerMask filter used to select which layers to detect Colliders for.

Returns

RaycastHit2D[] The ray intersection results.

Description

Cast a 3D ray against the 2D Colliders in the Scene.

This function acts as a 3D "ray cast" but specifically designed to detect 2D Colliders. It achieved this by projecting the 3D ray into 2D space and then performs the 2D intersection test, ordering the results by the Z direction of the original 3D ray.
