    I've figured out how to check animator bools in an 'if' statement by using GetBool, - if (anim.GetBool("isMoving")) - but for some reason, the same process isn't working for floats (GetFloat). How can this be done?

    Also, how can it be done with SetTrigger?

    What trouble are you having with GetFloat?

    It just gives me an error no matter what I do. I can't specify the float for my Speed condition (0.2f when walking, 0f when not walking). It either tells me I can't convert type float to bool or that no overload for GetFloat takes two arguments.

    These error messages indicate that you have a syntax error in your code. It has nothing to do with GetFloat working or not. If you post the code maybe someone can point out the errors.

    If your getting an error message like "cannot convert 'float' to 'bool'" then you're probably doing something like this:
    Code (csharp):
    1. if (anim.GetFloat("Speed"))
    Remember that "if()" requires a Boolean expression in the parentheses in order to work. If you use a float in an "if" statement it's usually in the form of a comparison, like "if (Speed > 2f)" or something like that. "Speed > 2f" will either be true or false.

    Ahh. I see. I did try...

    Code (CSharp):
    1.     if (anim.GetFloat("Speed") == true/false)
    2.  
    ...or put an exclamation mark at the start if it was false, thinking that would work, but nada. Thanks though; I'll give that a try. :) How would you do it for checking triggers?

    Hmm... I'm trying if (anim.GetFloat("Speed" > 2f)), but it doesn't appear to be working either. I've tried a couple of ways, such as removing the quotations, but nothing. :-\

    Code (csharp):
    1. if (anim.GetFloat("Speed") > 2f)
    Also, why not just check the float that is driving the animator's Speed variable?

    There must be some code like:
    Code (csharp):
    1. anim.SetFloat("Speed", myActualSpeedVariable);
    So just check myActualSpeedVariable instead.
    Code (csharp):
    1. if (myActualSpeedVariable > 2f)

    Again, how can it, or is it possible, to do the same thing with SetTrigger?
