Object.FindObjectsByType

パラメーター

戻り値

Object[] 指定した型で見つかったオブジェクトの配列を返します。

説明

Retrieves a list of all loaded objects of Type type.

This doesn't return Assets (for example meshes, textures, or prefabs). It also doesn't return objects that have HideFlags.DontSave set. Use Resources.FindObjectsOfTypeAll to avoid these limitations.

In Editor, this searches the Scene view by default. If you want to find an object in the Prefab stage, see the StageUtility APIs.

using UnityEngine;

// Ten GameObjects are created and have TextMesh and
// CanvasRenderer components added.
// When the game runs press the Space key to display the
// number of TextMesh and CanvasRenderer components.

public class ScriptExample : MonoBehaviour
{
    private const int count = 10;

    void Start()
    {
        var gameObjects = new GameObject[count];
        var expectedTextMeshObjects = new TextMesh[count];
        var expectedCanvasObjects = new CanvasRenderer[count];

        for (var i = 0; i < count; ++i)
        {
            gameObjects[i] = new GameObject();
            expectedTextMeshObjects[i] = gameObjects[i].AddComponent<TextMesh>();
            expectedCanvasObjects[i] = gameObjects[i].AddComponent<CanvasRenderer>();
        }
    }

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            var foundCanvasObjects = FindObjectsByType<CanvasRenderer>(FindObjectsSortMode.None);
            var foundTextMeshObjects = FindObjectsByType(typeof(TextMesh), FindObjectsSortMode.None);
            Debug.Log(foundCanvasObjects + " : " + foundCanvasObjects.Length);
            Debug.Log(foundTextMeshObjects + " : " + foundTextMeshObjects.Length);
        }
    }
}
