I won't be making an Action to replicate what GetAxisVector does. Rewired provides input. It does not provide in interpretation/use of that input. IE: transforming input into other spaces, moving objects, etc. That is beyond the scope of the system. It would quickly snowball into a gigantic monster with an infinite number of expected actions/methods for every different use case everyone has.
The proper way to do something like this is to separate the "getting the input value" and "transforming the input value" into two separate actions. Then you simply get the input, store it in a variable, then transform the input and apply it to whatever you want to apply it to.
