GUIElement.HitTest 位置检测

function HitTest (screenPosition : Vector3, camera : Camera = null) : bool


Is a point on screen inside the element.


Returns true if the screenPosition is contained in this GUIElement. screenPosition is specified in screen coordinates, like the values returned by Input.mousePosition property. If no camera is given a camera filling the entire game window will be assumed.


Note that if the position is inside the element, true will be returned even if the game object belongs to Ignore Raycast layer (normally mouse events are not sent to Ignore Raycast objects).



using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public void Awake() {
		if (guiText.HitTest(new Vector3(360, 450, 0)))
			print("This gui texture covers pixel 360, 450");

if (guiText.HitTest (Vector3(360, 450, 0)))
	print ("This gui texture covers pixel 360, 450");
