EventSystem.SetSelectedGameObject

설명

Set the GameObject as selected. Will send an OnDeselect the the old selected object and OnSelect to the new selected object.

Sets a GameObject as selected in the EventSystem. Make sure you have an EventSystem in your Scene. This sends an OnDeselect to the old selected GameObject and an OnSelect to the new selected GameObject.

//This script shows how you set a non-UI GameObject as the current selected in the EventSystem by clicking on it.
//Make sure to assign a PhysicsRaycaster component to your Main Camera.
//Make sure your Scene has an EventSystem

//Attach this script to a GameObject. Create some other GameObjects to test on.
//In Play Mode, click on GameObjects to see the current selected be output to the console
