    Hello, I´m having some issues to have a value clamped.
    I have used the function " Mathf.Clamp( value, -2, 2 )", but it doesnt work for my case.
    The range of the input value is between (0-180) and the output value is between (-2,2).
    What am I doing wrong?
    Thanks in advance.

    So you know, saying "doesn't work" does not describe a problem.

    Are you trying to rescale a range of 0 to 180 to a range of -2 to 2? If so, the Clamp method isn't for that. It, well, clamps so any value < -2 it just returns -2 and the same if the value > +2 it just returns +2.

    Yes I´m trying to rescale the value as you say, sorry for my english. When the input value is 0 I have the output to be -2 and when input is 180 the output is 2. That is what I want.

    You do know, that the Clamp method returns the clamped value, it does not (or technically can not) modify the passed in value. No method can do that except for ref parameters.
