Scripting API: LayerMask

A GameObject can use up to 32 LayerMasks supported by the Editor. The first 8 of these Layers are specified by Unity; the following 24 are controllable by the user.

Bitmasks represent the 32 Layers and define them as true or false . Each bitmask describes whether the Layer is used. As an example, bit 5 can be set to 1 ( true ). This will allow the use of the built-in Water setting.

Edit->Settings->Tags and Layers option shows the use of the 32 bitmasks. Each Layer is shown with a string setting. As an example Built-in Layer 0 is set as Default ; Built-in Layer 1 is set as TransparentFX . New named Layer s are added above bitmask layer 8. A selected GameObject will show the chosen Layer at top right of the Inspector. The example below has User Layer 13 set to “Wall”. This causes the assigned GameObject to be treated as part of a building.

In the following script example, Physics.Raycast sends a ray into the world. Camera.main can be rotated around the y-axis and fire a ray. Three GameObjects represent walls that can be hit by the fired ray. Each GameObject has GameObject.label set to the “Wall” layerMask.

[Unity] Raycast Layermask 설정

Raycast 를 사용하여 타겟에게 ray 를 쏴서 처리하고 있을때

자신과 타겟사이에 오브젝트가 끼어들면 ray를 쏘지 못하게 되죠.

당연한 말이지만, raycast 사용중 자신과 타겟사이에 오브젝트가 끼어들어도 계속 타겟에게 ray를 쏘고 싶을때가 있습니다.

이럴경우 layermask를 쓰면 아주 좋은데요 , 우선 Raycast 오버로딩된 함수에 layermask를 어덯게 넣고 쓰는지 알아 보겟습니다.

우선 아래 사진처럼 타겟대상(사진에선 Player) 에게 Layer 를 설정해주세요

이제 자신에 해당하는 스크립트에 raycast 사용시 아래와같이 layermask 변수를 넣어주세요

1 2 3 4 //특정 Layer만 raycast하기 RaycastHit hit; float distance = 10f; int layerMask = 1 << LayerMask.NameToLayer("Player"); // Player 레이어만 충돌 체크함 Physics.Raycast (transform.position, transform.TransformDirection (Vector3.forward), out hit, distance ,layerMask); cs 그러면 raycast시 타겟 사이에 다른 오브젝트가 껴도 타겟만 쏘게 됩니다. 아래에 layermask 다른 예시가 있습니다. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 //특정 Layer만 raycast하기 int layerMask = 1 < < LayerMask.NameToLayer( "Player" ); // Player 레이어만 충돌 체크함 Physics.Raycast (transform.position, transform.TransformDirection (Vector3.forward), hit, Mathf.Infinity, layerMask); //두개 레이어 raycast하기 int layerMask = ( 1 < < LayerMask.NameToLayer( "Player" )) + ( 1 < < LayerMask.NameToLayer( "MyTeammate" )); // Player 와 MyTeammate 레이어만 충돌체크함 Physics.Raycast (transform.position, transform.TransformDirection (Vector3.forward), hit, Mathf.Infinity, layerMask); //특정 layer만 raycast제외하기 (1) int layerMask = ( - 1 ) - ( 1 < < LayerMask.NameToLayer( "Player" )); // Everything에서 Player 레이어만 제외하고 충돌 체크함 Physics.Raycast (transform.position, transform.TransformDirection (Vector3.forward), hit, Mathf.Infinity, layerMask); //특정 layer만 raycast제외하기 (2) int layerMask = ( 1 < < LayerMask.NameToLayer( "Player" )); // Everything에서 Player 레이어만 제외하고 충돌 체크함 layerMask = ~layerMask ; Physics.Raycast (transform.position, transform.TransformDirection (Vector3.forward), hit, Mathf.Infinity, layerMask); //특정 2개이상 layer raycast 제외하기 int layerMask = (( 1 < < LayerMask.NameToLayer( "Player" )) | ( 1 < < LayerMask.NameToLayer( "GUN" ))); // Everything에서 Player,GUN 레이어만 제외하고 충돌 체크함 layerMask = ~layerMask ; Physics.Raycast (transform.position, transform.TransformDirection (Vector3.forward), hit, Mathf.Infinity, layerMask); Colored by Color Scripter cs 이상입니다. 반응형

unity3d Tutorial => LayerMask Structure

Example

The LayerMask structure is an interface that functions almost exactly like passing an integer to the function in question. However, its biggest benefit is allowing the user to select the layer in question from a drop-down menu in the inspector.

using UnityEngine; class LayerMaskExample{ public LayerMask mask; public Vector3 direction; void Start() { if(Physics.Raycast(transform.position, direction, 35f, mask)) { Debug.Log(“Raycast hit”); } { }

It also has multiple static functions that allow for converting layer names to indices or indices to layer names.

using UnityEngine; class NameToLayerExample{ void Start() { int layerindex = LayerMask.NameToLayer(“Obstacle”); { }

In order to make Layer checking easy define the following extension method.

public static bool IsInLayerMask(this GameObject @object, LayerMask layerMask) { bool result = (1 << @object.layer & layerMask) == 0; return result; } This method will allow you to check whether a gameobject is in a layermask (selected in the editor) or not.
