Switch to Manual
public Vector3 ScreenToWorldPoint (Vector3 position);

Description

Преобразует position (позицию) из экранного пространства в мировое пространство.

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.

// Convert the 2D position of the mouse into a
// 3D position.  Display these on the game window.

using UnityEngine;

public class ExampleClass : MonoBehaviour { private Camera cam;

void Start() { cam = Camera.main; }

void OnGUI() { Vector3 point = new Vector3(); Event currentEvent = Event.current; Vector2 mousePos = new Vector2();

// Get the mouse position from Event. // Note that the y position from Event is inverted. mousePos.x = currentEvent.mousePosition.x; mousePos.y = cam.pixelHeight - currentEvent.mousePosition.y;

point = cam.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, cam.nearClipPlane));

GUILayout.BeginArea(new Rect(20, 20, 250, 120)); GUILayout.Label("Screen pixels: " + cam.pixelWidth + ":" + cam.pixelHeight); GUILayout.Label("Mouse position: " + mousePos); GUILayout.Label("World position: " + point.ToString("F3")); GUILayout.EndArea(); } }
