Camera.WorldToViewportPoint

function WorldToViewportPoint (position : Vector3) : Vector3

Description

Transforms position from world space into viewport space.

Viewport space is normalized and relative to the camera. The bottom-left of the camera is (0,0); the top-right is (1,1). The z position is in world units from the camera.

JavaScripts

// Finds out whether target is on the left or right side of the screen
var target : Transform;

function Update () {
var viewPos : Vector3 = camera.WorldToViewportPoint (target.position);
// viewport coordinates range from zero to one
if( viewPos.x > 0.5 )
print ("target is on the right side!");
else
print ("target is on the left side!");
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
public Transform target;
void Update() {
Vector3 viewPos = camera.WorldToViewportPoint(target.position);
if (viewPos.x > 0.5F)
print("target is on the right side!");
else
print("target is on the left side!");
