LayerMask.LayerMask

说明

隐式地将整数转换为 LayerMask。

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Converts an int to a layer mask and prints all the layer names.
        // As the value is 3, it will print "Default" and "TransparentFX".
        // 2^0 + 2^1 = 1 + 2 = 3

        int number = 3;
        LayerMask layerMask;
        layerMask = number;
        for (int i = 0; i < 32; i++)
        {
            if ((layerMask.value & (1 << i)) != 0)
            {
                Debug.Log($"Layer {i}: {LayerMask.LayerToName(i)}");
            }
        }
    }
}
