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.
// 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. using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { void OnDrawGizmosSelected() { Camera camera = GetComponent<Camera>(); Vector3 p = camera.ScreenToWorldPoint(new Vector3(100, 100, camera.nearClipPlane)); Gizmos.color = Color.yellow; Gizmos.DrawSphere(p, 0.1F); } }
