Function Description

 

Static raycasthit2d []Raycastall (vector2Origin, vector2Direction, floatDistance = mathf. Infinity, intLayermask = defaultraycastlayers, floatMindepth =-mathf. Infinity, floatMaxdepth = mathf. Infinity ); Parameters

Origin	The point in 2D space where the ray originates.
Direction	Vector representing the direction of the ray.
Distance	Maximum distance over which to cast the ray.
Layermask	Filter to detect coldocumers only on certain layers.
Mindepth	Only include objects with a Z coordinate (depth) greater than this value.
Maxdepth	Only include objects with a Z coordinate (depth) less than this value.

Description

Casts a ray against colcyclers in the scene, returning all colcyclers that contact with it. Launch a ray in the scene to detect all collision machines (Collider)

1. // Layermask parameter indicates the layer to be ignored. The element attribute in the editor is sprite Renderer-> order in Layer
2. // Set the object to be ignored as the corresponding layer, and then define layermask in the raycastall function as this layer. Then the ray will ignore this layer.
3. Raycasthit2d [] rharfirst = physics2d. raycastall (qieobject. Transform. Position, vectordir, stagemanager. elementsize, 3 );
