Camera.ScreenToWorldPoint 屏幕转世界位置

function ScreenToWorldPoint (position : Vector3) : Vector3


Transforms position from screen space into world space.


Screenspace is defined in pixels. The bottom-left of the screen is (0,0); the right-top is (pixelWidth,pixelHeight). The z position is in world units from the camera.


using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void OnDrawGizmosSelected() {
		Vector3 p = camera.ScreenToWorldPoint(new Vector3(100, 100, camera.nearClipPlane));
		Gizmos.color = Color.yellow;
		Gizmos.DrawSphere(p, 0.1F);
// Draw a yellow sphere in the scene view at the position
// on the near plane of the selected camera that is
// 100 pixels from lower-left.
function OnDrawGizmosSelected () {
	var p : Vector3 = camera.ScreenToWorldPoint (Vector3 (100,100,camera.nearClipPlane));
	Gizmos.color = Color.yellow;
	Gizmos.DrawSphere (p, 0.1);
