Camera.WorldToViewportPoint

Descripción

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.

	// Finds out whether target is on the left or right side of the screen

using System.Collections;

public class ExampleClass : MonoBehaviour {

    	camera = GetComponent<Camera>();
    }
    
    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!");
    }
