String to KeyCode in C#

Question

Hey guys,

I've been working on this for an hour now. I'm sure it's simple but my lack of knowledge seems to get the best of me.

I'm trying to get a string to get converted into a KeyCode. Here is my code:

 using UnityEngine;
 using System.Collections;
 using System;

     public string joystickButton = "JoystickButton9";
     public KeyCode thisKeyCode = Enum.Parse(KeyCode, joystickButton);

My big plan later will be to concatenate these strings so that I can add this base script to a character. Then change the characters joystick and control him with that.

pseudo code:

 public int player = 4
 joystickButton = "Joystick" + player.toString() + "Button9";

KeyCode thisKeyCode = (KeyCode) System.Enum.Parse(typeof(KeyCode), "Whatever") ;

I'm getting this error when I don't input a string like you have it.

error CS1503: Argument #2' cannot convert object' expression to type `string'

 public string joystickButton = "JoystickButton9";
     public KeyCode thisKeyCode =(KeyCode) System.Enum.Parse(typeof(KeyCode), joystickButton);

Assign it in a function. eg :

 public string jsButton = "JoystickButton9" ;
 public KeyCode kc ;
 
 void Awake()
 {
    kc = (KeyCode)System.Enum.Parse(typeof(KeyCode), jsButton) ;
 }

Thank you so much. Could you explain why it needs to be done this way? I want to learn more of this programming stuff so that I'm able to help other while I hop on the forums.

It doesn't need to be converted to a KeyCode, you can also just pass it a string, but 'JoystickButton9' is not what it's called with a string. If you check out the input section in the manual it has a list of all the names(ctrl+f 'button names').

I think @Funlamb was asking why it needed to be assigned inside a function instead of at it's declaration @ @Josh707... And I actually don't know why, all I know is that's how it works so that's how I do it. Food makes me not-hungry, so I eat it; I don't question why it makes me not-hungry so long as it does what I want it to do lol
