public Vector3 ScreenToWorldPoint (Vector3 position);

説明

Transform position のスクリーン座標からワールド座標に変換します。

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 { void OnGUI() { Vector3 p = new Vector3(); Camera c = Camera.main; Event e = Event.current; Vector2 mousePos = new Vector2();

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

p = c.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, c.nearClipPlane));

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