Überprüfen Sie, ob sich die Maus in der Rahmeneinheit befindet
// If you want to hide the mouse when it is in frame, use this:
var mouseLocation = Camera.current.ScreenToViewportPoint(Input.mousePosition);
var outOfFrame = Mathf.Min(mouseLocation.x, mouseLocation.y) < 0 ||
Mathf.Max(mouseLocation.x, mouseLocation.y) > 1;
UnityEngine.Cursor.visible = outOfFrame;
// If you want to prevent the mouse from leaving frame:
UnityEngine.Cursor.lockCursor = true;
