Object.FindObjectsOfType

Parameters

Returns

T[] The array of objects found matching the type specified.

Description

Returns a list of all active loaded objects of Type type.

This does not return assets (such as meshes, textures or prefabs), or objects with HideFlags.DontSave set. Objects attached to inactive GameObjects are only included if inactiveObjects is set to true. 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.

Note: This function is very slow. It is not recommended to use this function every frame. In most cases you can use the singleton pattern instead.

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.
