Help with Strings!

Questions & Answers
1

So I’m making some kind of Minecraft command block. I really need help with the strings.
Heres my code:

var stringToEdit : String = “/type in here”;
var clicked : boolean = false;
var killCommand = “/kill”;
var testCommand = “/test”;
var btnTexture : Texture;

		function Update()
		{
		if(killCommand == "/kill")
	 	    {
   	 			print("Profanity Found");
			}
		}
		//function Update(){
		//CheckCode
			 //if(killCommand == "/kill" || killCommand == "/Kill")
     		//{
     			//Debug.Log("Killed the player");
     			//Application.LoadLevel(Application.loadedLevel);	
     			
     			
     			
	//}
//}

function OnMouseDown(){
		if(Input.GetMouseButtonDown (0))
		{
			clicked = true;
		}
	}
	
function OnGUI () {
	if(clicked == true)
	{
	// Make a text field that modifies stringToEdit.
	stringToEdit = GUI.TextField (Rect (0, 0, 200, 20), stringToEdit, 35);



	}
}

But for some reason I can’t get this to work. The part I need help with is:
function Update()
{
if(killCommand == “/kill”)
{
print(“Profanity Found”);
}
}
I’m going to have multible commands like this. Please Help!!

The main problem in your script seems to be that you never assign the text from the text field to a variable that gets checked for its content. You need to get what the player has typed in and then check if it was a command that your game recognizes.

Here is a modified version that should do approximately what you want.

#pragma strict

//The string that is edited in the text field
public var stringToEdit : String;
//The command as entered by the player
public var command : String;

//Boolean to track when the player clicks to enable the text field
public var clicked : boolean;
//Boolean to track when the player has confirmed the command to enter
public var shouldCheckCommand : boolean;

public var btnTexture : Texture;

function Start()
{
	//Initialize variables
	stringToEdit = "/type in here";
	clicked = false;
	shouldCheckCommand = false;
}

function Update()
{
	//Check for the mouse click - the text field is invisible
	if(Input.GetMouseButtonDown (0) && clicked == false)
    {
    	//Reset the string to default
    	stringToEdit = "/type in here";
		clicked = true;
	}
	//Check for the Return/Enter key - the text field is visible
	else if (Input.GetKeyDown(KeyCode.Return) && clicked == true)
	{
		command = stringToEdit; //Here is the key part - the string from the text field is assigned to the command variable
		clicked = false;
		shouldCheckCommand = true;
	}
	
	//Check if the player has confirmed the command entered
	if (shouldCheckCommand == true)
	{
		CheckCommand();
	}
}

function CheckCommand()
{
	//Check which command was entered and take the appropriate action
	if (command == "/kill" || command == "/Kill")
	{
		Debug.Log("Kill the player");
	}
	
	shouldCheckCommand = false;
}
     
function OnGUI()
{
	if(clicked == true)
    {
    	stringToEdit = GUI.TextField (Rect (0, 0, 200, 20), stringToEdit, 35);
	}
}

This script activates the text field on a mouse click. Once the command is entered, clicking outside the text field to deselect it and hitting the Return key will “enter” the command.
