Question by Zyu · Nov 13, 2011 at 04:47 AM · mouserectlockareain

How do I lock the mouse in an area?

The problem I have right now is that I can lock my mouse texture to an rect using Mathf.clamp, but now the actual mouse.

Is there anyway to clip the actual mouse/cursor in a similar fashion as my mouse texture?

Or just hide it using: Screen.showCursor = false;

Hiding it doesn't do what I want as the mouse can still move out of the area.

The mouse position is not at all related to unity, Thats the job of user32.dll. I suppose you could read up on it, but its going to be whole lot more complicated than:

     Vector2 mousePos;
     float leftBound;
     float rightBound;
     float bottomBound;
     float topBound;

     mousePos.x = Mathf.Clamp(Input.mousePosition.x, leftBound, rightBound);
     mousePos.y = Mathf.Clamp(Input.mousePosition.y, bottomBound, topBound);
     Input.mousePosition = mousePos; // too bad its read only.
