Restrict the mouse posisition

Question

Hey guys,

I was wondering how I would restrict how far the mouse can go on the screen... I was thinking about using mathf.clamp, but I don't really know how... Anyway, if you guys can help, that would be great!

//Written By/For Gibson Bethke var crosshairTexture : Texture2D;

function Update () {
    Screen.showCursor = false;
}

function OnGUI () {
    var mousePos = Event.current.mousePosition;
    GUI.DrawTexture( Rect( mousePos.x - (crosshairTexture.width/2),
                           mousePos.y - (crosshairTexture.height/2),
                           crosshairTexture.width,
                           crosshairTexture.height), crosshairTexture);
}

Just incase I wasn't clear, I want the mouse to stop before it hits the sides of the screen, much like this (but with the mouse):

//Written By/For Gibson Bethke var normalMoveSpeed : float = 3.125; var topMoveSpeed : float = 6.25; var currentSpeed : float = 3.125;

function Update () {
    var down = Vector3(0, -1, 0);

     if(Input.GetButton("Jump")) {
         currentSpeed = topMoveSpeed;
     }else{
         currentSpeed = normalMoveSpeed;
     }
         if(Input.GetButton("W")) {
             transform.Translate(Vector3.up * currentSpeed);
     }
         if(Input.GetButton("A")) {
             transform.Translate(Vector3.left * currentSpeed);
     }
         if(Input.GetButton("S")) {
             transform.Translate(Vector3.down * currentSpeed);
     }
         if(Input.GetButton("D")) {
             transform.Translate(Vector3.right * currentSpeed);
     }
      var xMove : float = Input.GetAxis("Horizontal") * Time.deltaTime * 20;
         transform.Translate(Vector3(xMove,0,0));
         transform.position.x = Mathf.Clamp(transform.position.x, 300, 1700); 

     var zMove : float = Input.GetAxis("Vertical") * Time.deltaTime * 20;
         transform.Translate(Vector3(zMove,0,0));
         transform.position.z = Mathf.Clamp(transform.position.z, 300, 1700);

-Thanks so much for your help!

P.s. Both the scripts work, the top one is what I have so far

Set minX, maxX, minY, maxY to the values you want it to clamp between.

mousePos.x = Mathf.Clamp(mousePos.x, minX, maxX);
mousePos.y = Mathf.Clamp(mousePos.y, minY, maxY);

function OnGUI () { var mousePos = Event.current.mousePosition;

 mousePos.x = Mathf.Clamp(mousePos.x, minX, maxX);
 mousePos.y = Mathf.Clamp(mousePos.y, minY, maxY);

 GUI.DrawTexture( Rect( mousePos.x - (crosshairTexture.width/2),
                        mousePos.y - (crosshairTexture.height/2),
                        crosshairTexture.width,
                        crosshairTexture.height), crosshairTexture);

It says: $$anonymous$$ identifier: 'mousePos'.

Well, you need to have a mousePos. Just add it where you have one.

There we go, it worked! Thanks

Do you think you could answer one more question? How would I restrict the mouse's movement speed?

I guess you could sample the position and store it to the next frame. Then use Vector3.Clamp$$anonymous$$agnitude on the delta. http://unity3d.com/support/documentation/ScriptReference/Vector3.Clamp$$anonymous$$agnitude.html

easy way I use to restrict cursor to a distance from edges of screen: use the newMousePos as your cursor value.

   public float mousePosX_min;
   public float mousePosX_max;
   public float mousePosY_min;
   public float mousePosY_max;
 
 void Update()
 {
       float mousePosX = Mathf.Clamp(Input.mousePosition.x,mousePosX_min, mousePosX_max); 
       float mousePosY = Mathf.Clamp(Input.mousePosition.y,mousePosY_min, mousePosY_max); 
       newMousePos = new Vector2(mousePosX,mousePosY);
 }

float mousePosX = Mathf.Clamp(Input.mousePosition.x, minClamp, maxClamp); float mousePosY = Mathf.Clamp(Input.mousePosition.y, minClamp, maxClamp); Vector2 newMousePos = new Vector2(mousePosX, mousePosY); mousePosition = newMousePos;

nothing happened
