Question by omnirusted · Sep 11, 2013 at 12:30 AM · mousezoomrtsscrollwheel

Mouse Wheel Zoom code not working like it should

I have an RTS style top-down / isometric view control scheme that I am attempting to work on.

So far I have WASD and Keypad controlling movement going Left, Right, Forward, and Backwards.

I am attempting to add a "Zoom" function to "Mouse Scrollwheel" that effects the FOV of the camera. The code I have SHOULD work, yet it's not doing anything. And yes, I have tested, my Mouse Wheel works just fine.

Here is my code (including Keyboard Movement):

// Camera Scroll Speed var scrollSpeed : float = 20.0;

function Update () {

     var fwdBack : float = Input.GetAxis ("Vertical") * scrollSpeed;
     var leftRight : float = Input.GetAxis ("Horizontal") * scrollSpeed;
     
     fwdBack *= Time.deltaTime;
     leftRight *= Time.deltaTime;
     
     transform.Translate (leftRight, 0, 0);
     transform.Translate (0, 0, fwdBack);

     // Mouse Scroll Wheel Zoom
             //------------------Code for Zooming Out------------
     if (Input.GetAxix("Mouse ScrollWheel") <0)
     {
         if (Camera.main.fieldOfView<=100) {
             Camera.main.fieldOfView +=2; }
         if (Camera.main.orthographicSize<=20) {
             Camera.main.orthographicSize +=0.5; }
     }

         //----------------Code for Zooming In-----------------------
     if (Input.GetAxis("Mouse ScrollWheel") > 0)
     {
         if (Camera.main.fieldOfView>2) {
             Camera.main.fieldOfView -=2; }
         if (Camera.main.orthographicSize>=1) {
             Camera.main.orthographicSize -=0.5; }
     }

 }

    // Mouse Scroll Wheel Zoom
          //------------------Code for Zooming Out------------
     if (Input.GetAxis("Mouse ScrollWheel") <0)
     {
        if (Camera.main.fieldOfView<=100) {
          Camera.main.fieldOfView +=2; }
        if (Camera.main.orthographicSize<=20) {
          Camera.main.orthographicSize +=0.5; }
     }

Input.GetAxis was Input.GetAxix

Works for me when I changed it. If it's not there, try adding '#pragma strict' to the top of your code. Should have the compiler catch that sorta thing. Best of luck!
