Unity Engine
1

Hi everyone, i have a question about the Input Manager, i would to know if i can modify the Input Manager by scripting. I will make a configuration section for my game, and i want to do to the player, the possibility to modify the keys that is used in the game. So, since I use Input Manager to manage the keys, i need to modify that keys in the Input Manager, not in my scripts. Then, i can do this? How?
(Sorry for bad english, is google translate :smile:)

You can’t but its pretty easy to make your InputManger

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System;

public static class GameInputManager
{
    static Dictionary<string, KeyCode> keyMapping;
    static string[] keyMaps = new string[6]
    {
        "Attack",
        "Block",
        "Forward",
        "Backward",
        "Left",
        "Right"
    };
    static KeyCode[] defaults = new KeyCode[6]
    {
        KeyCode.Q,
        KeyCode.E,
        KeyCode.W,
        KeyCode.S,
        KeyCode.A,
        KeyCode.D
    };

    static GameInputManager()
    {
        InitializeDictionary();
    }

    private static void InitializeDictionary()
    {
        keyMapping = new Dictionary<string, KeyCode>();
        for(int i=0;i<keyMaps.Length;++i)
        {
            keyMapping.Add(keyMaps[i], defaults[i]);
        }
    }

    public static void SetKeyMap(string keyMap,KeyCode key)
    {
        if (!keyMapping.ContainsKey(keyMap))
            throw new ArgumentException("Invalid KeyMap in SetKeyMap: " + keyMap);
        keyMapping[keyMap] = key;
    }

    public static bool GetKeyDown(string keyMap)
    {
        return Input.GetKeyDown(keyMapping[keyMap]);
    }
}

Then use it like this:

void Update()
{
      if (GameInputManager.GetKeyDown("attack"))
      {
            // attack code
      }
}

This will not only let you customize the keys but you can create whatever names you want, not just the few default ones that Unity provides. I only showed code to Initialize and set up new keymappings. As well as one GetKeyDown function. You’d want to extend this out all the normal functions (GetKey, GetKeyUp, etc)

This is helpful for keyboard input. Any chance you could add support for joystick (Xbox controller) input?

No. Unity keeps promising us a configurable input manager. But so far nothing.

Common practice is to fill the gap with something like rewired from the asset store.

Get a Custom Input Manager, it’s free and already supports controllers GitHub - daemon3000/InputManager: Custom InputManager for Unity
