var as Input

Unity Engine

is there a way of using var as input, so if you have multiple players you could use only one script and change the input buttons in the inspector?

What do you mean by “Input”? Are you referring to the class?

Not entirely sure what you mean by “var” in this context.

If you’re using Unity’s keyboard input functions like GetButton and GetAxis and you’re trying to make it so that different instances of a script will read different inputs, you can use string-type variables to represent the inputs you should check. (But beware of spelling errors.)

if (Input.GetButtonDown(myStringVar))

You could even build the input names programmatically if they’re somehow derived from the player number. For instance, if you had inputs with names like “player0fire”, “player1fire”, “player0jump”, “player1jump”, etc. then you could get input with something like

if (Input.GetButtonDown("player" + playerNum + "fire"))

or, perhaps a little more neatly,

if (Input.GetButtonDown(string.Format("player{0}fire", playerNum)))

But Unity’s Input class doesn’t have a built-in concept of “players”, so that only works as long as you manually set up all of your input names to fit the pattern.

There are plugins on the asset store you can get that will assist with certain kinds of input processing if you want; I’ve recently been using Rewired.

This is working very well, I will change all the code, so player 2 have the same code but the input keys will be the arrows instead of wasd
