Making an in-game command line. How do I get arguments?

I have a debug console that I use to do things in game rather than doing the continuous hastle of doing everything in code and in the editor. So far there is a simple command called “addItem” and then I have the commands “setHealth”, “setHunger” etc… But I dont want to make an if for each value. e.g 1, 2, 3, 4 etc…

EDIT: Make sure you look at ‘ExecuteCommand’ method, here lies my problem. I need to find arguments in the string ‘inputText’. How do I go about doing that?

How do I check and read arguments? Here is my code:

using UnityEngine;
using System.Collections;

public class DebugConsole : MonoBehaviour {

	public string COMMAND_addItem = "addItem";
	public string inputText;
	private string log;

	public bool commandLine = false;
	private bool enterPressed;
	private bool allowCheats = false;

	PlayerInventory playerInventory;

	void Start () {
		playerInventory = GameObject.FindGameObjectWithTag("Player").GetComponent<PlayerInventory>();
		log += "

Tip: Press ESCAPE to exit debug console";
}

	void Update () {
		if(Input.GetKeyDown ("`"))
			commandLine = !commandLine;
		if(Input.GetKeyDown (KeyCode.Escape) && commandLine)
			commandLine = false;
	}

	void OnGUI () {
		enterPressed = false;
		if(commandLine){
			Event e = Event.current;
			if(e.type == EventType.KeyDown && e.keyCode == KeyCode.Return && GUI.GetNameOfFocusedControl() == "debugInput")
				enterPressed = true;
			if(e.type == EventType.KeyDown && e.keyCode == KeyCode.Escape && GUI.GetNameOfFocusedControl() == "debugInput"){
				commandLine = false;
				PauseMenu.paused = false;
			}
			GUI.SetNextControlName("debugInput");
			inputText = GUI.TextField(new Rect(10, 25, Screen.width - 20, 25), inputText, 50);
			GUI.Box (new Rect(10, 55, Screen.width - 20, 400), log);
			if(enterPressed){
				if(inputText == ""){
					commandLine = false;
				} else {
					ExecuteCommand(inputText);
					inputText = "";
				}
			}
		}
	}

	void ExecuteCommand(string command){
		//addItem
		if(allowCheats){
			if(command == "addItem 0"){
				playerInventory.AddItem(0);
				log += "

Adding item ID 0 (FRUIT_APPLE) to your inventory";
} else if(command == “addItem 1”){
log += "
Cannot add item ID 1 to inventory. Item ID ‘1’ is NULL";
} else if(command == “addItem 2”){
playerInventory.AddItem(2);
log += "
Adding item ID 2 (FRUIT_ORANGE) to your inventory";
}
}

		//allowCheats
		if(command == "allowCheats true"){
			allowCheats = true;
			log += "

Cheats set to: true (Allowed)“;
} else if (command == “allowCheats false”){
allowCheats = false;
log += "
Cheats set to: false (Disallowed)”;
}

		//setStatus
		if(allowCheats){
			if(command.StartsWith("setHealth")){
				
			} else if(command.StartsWith("setHunger")){
				
			} else if(command.StartsWith("setThirst")){
				
			} else if(command.StartsWith("setStamina")){
				
			}
		} else {
			log += "<color=red>Not allowed to use cheats!</color>";
		}
	}

}

Usually you’d use string functions to split the input string at spaces. The first part of the string before the first space is a command, and then the substrings after spaces are arguments.
