I want to save the basic 2D control for a character that the user provides before starting the time in scene.
and can anyone help me by telling the way by which i can move my character according to the input in array.
i’ve made a code but i am sure it doesn’t work but it explains the point well.

using UnityEngine;
using System.Collections;

public class charactercontrol : MonoBehaviour {

// Use this for initialization
void Start () {
	int[] instructions = new int[25];
}

// Update is called once per frame
void Update () {
	for (int i = 0; i < 5; i++)
		if (Input.GetKey ("up")) {
			instructions  *= 1;*
  •   	} else if (Input.GetKey ("right")) {*
    

_ instructions = 2;_
* }*
* else if (Input.GetKey (“down”)) {*
_ instructions = 3;
* }
else if (Input.GetKey (“left”)) {
instructions = 4;
}
}
}*_

I think you are on the right way.

Use a list to store the inputs, then make a switch to check each key

// Inputs list
	public List<string> inputKeys = new List<string>() ;
	
	void Update(){
		if(Input.GetKeyDown("down")){
			inputKeys.Add("down") ;
		}
		if(Input.GetKeyDown("right")){
			inputKeys.Add("right") ;
		}
		if(Input.GetKeyDown("left")){
			inputKeys.Add("left") ;
		}
		if(Input.GetKeyDown("up")){
			inputKeys.Add("up") ;
		}
		
		// Check the list and do whatever you want for each key string
		foreach(string key in inputKeys){
			switch(key){
				case "down" :
					break ;
				case "up" :
					break ;
				case "right" :
					break ;
				case "left" :
					break ;
			}
		}
	}
