public static int GetMask(params string[] layerNames);


layerNames List of layer names to convert to a layer mask.


int The layer mask created from the layerNames.


Given a set of layer names as defined by either a Builtin or a User Layer in the Tags and Layers manager, returns the equivalent layer mask for all of them.

using UnityEngine;

public class Example : MonoBehaviour { void Start() { Debug.Log(LayerMask.GetMask("UserLayerA", "UserLayerB")); } }

Note: Suppose UserLayerA and UserLayerB are the tenth and eleventh layers. These will have a User Layer values of 10 and 11. To obtain their layer mask value their names can be passed into GetMask. The argument can either be a list of their names or an array of strings storing their names. In this case the return value will be 2^10 + 2^11 = 3072.
