Question by jessee03 · Jun 02, 2015 at 01:05 AM · mathf.clamp

Error using return Mathf.Clamp

I'm still somewhat new to coding with C#, so I am unsure if there's a different way of doing this. I'm getting two errors with return Mathf.Clamp (angle, min, max);

Assets/NewScripts/UserCamera.cs(158,17): error CS0127: UserCamera.ClampAngle(float, float, float)': A return keyword must not be followed by any expression when method returns void Assets/NewScripts/UserCamera.cs(158,17): error CS0029: Cannot implicitly convert type float' to `void'

     void ClampAngle (float angle, float min, float max)
     {
         if (angle < -360)
             angle += 360;
         if (angle > 360)
             angle -= 360;
 return Mathf.Clamp (angle, min, max);

}

Your function is a "void" type, which means it has no return type.

That said, you don't appear to be changing any variables in the script through this function, so I would recommend using:

 float ClampAngle (float angle, float min, float max)

This would support your return call, which presently returns a "float" value.

Then, to utilize this function, you would use something like

 myAngle = ClampAngle(myAngle, minAngle, maxAngle);

in your script.

Here's the variables I'm transferring. Still get the void to float error when trying to use yDeg = ClampAngle(angle, $$anonymous$$, max); ins$$anonymous$$d of a return.

     public float y$$anonymous$$inLimit = -80;                 
     public float y$$anonymous$$axLimit = 80; 
     private float yDeg = 0.0f; 


     //call function
     ClampAngle (yDeg, y$$anonymous$$inLimit, y$$anonymous$$axLimit); 

     //new return
     yDeg = ClampAngle (yDeg, y$$anonymous$$inLimit, y$$anonymous$$axLimit);

Never$$anonymous$$d it seems when I did it this way that it fixed itself

 yDeg = $$anonymous$$athf.Clamp(angle, -80, 80);
