type | 要查找的对象类型。 |
Object[] 找到的与指定类型匹配的对象的数组。
返回所有类型为 type
的已加载的激活对象的列表。
该函数不返回任何资源(网格、纹理、预制件等)或非激活对象,也不返回设置了 HideFlags.DontSave 的对象。要避免这些限制,请使用 Resources.FindObjectsOfTypeAll。
请注意,该函数的运行速度非常缓慢。不建议对每一帧都使用该函数。
在大多数情况下,您可以改为使用单例模式。
using UnityEngine;
// Ten GameObjects are created and have TextMesh components added. // When the game runs press the Space key and the number of // TextMesh components are displayed.
public class ScriptExample : MonoBehaviour { private const int count = 10;
void Start() { var gameObjects = new GameObject[count]; var expectedObjects = new TextMesh[count];
for (var i = 0; i < count; ++i) { gameObjects[i] = new GameObject(); expectedObjects[i] = gameObjects[i].AddComponent<TextMesh>(); } }
void Update() { if (Input.GetKeyDown(KeyCode.Space)) { var foundObjects = FindObjectsOfType<TextMesh>(); Debug.Log(foundObjects + " : " + foundObjects.Length); } } }
