hey guys, i just quickly made a script to allow me to change my level through a text box, however i feel instead of using say “.ModLevel 2” i should be able to enter any amount.
for example if i entered “.ModLevel 10” i want to be able to add 10 without having “.ModLevel 10” as a pre defined variable.
heres the script :
```auto
var PlayerLevel =1;
var TextEnter = "Enter Text";
var Mod1 = ".ModLevel 1";
var Mod2 = ".ModLevel 2";
var B1 = 10;
var B2 = 20;
var B3 = 60;
var B4 = 50;
var E1 = 20;
var E2 = 20;
var T1 = 20;
var T2 = 20;
var T3 = 20;
var T4 = 20;
var ShowTextBox : boolean = true;
function Update () {
if(TextEnter == Mod1 Input.GetKeyDown("return")) {
ShowTextBox = false;
PlayerLevel = 1;
TextEnter = "Enter Text";
TextBox ();
}
if(TextEnter == Mod2 Input.GetKeyDown("return")) {
ShowTextBox = false;
PlayerLevel = 2;
TextEnter = "Enter Text";
TextBox ();
}
}
function OnGUI () {
GUI.Label (Rect(B1,B2,B3,B4),""+ (Money.Gold ));
GUI.Label (Rect(E1,E2,B3,B4),"Lv." + (PlayerLevel));
if(ShowTextBox) {
TextEnter = GUI.TextField (Rect (T1,T2,T3,T4), TextEnter, 50);
}
}
function TextBox () {
ShowTextBox = true;
}
```

if it helps, i knew you could do somthing like this in python, i can’t rember exactly but you can build strings using parts like {0} walked to a town and {1} {2}
0,1 and 2 would be replaced with somthing, but you could also insert stuff with a similar option and it would be stored as a variable

There are a couple of functions in the .NET library that will help here.
[String.LastIndexOf](http://msdn.microsoft.com/en-us/library/1wdsy8fy.aspx) returns the rightmost position in the string where a particular character or substring occurs. You can use this to detect where the space is in your source string. Then, you can use [String.Substring](http://msdn.microsoft.com/en-us/library/hxthx5h6.aspx) to extract the portion that follows the space. Finally, [Int32.Parse](http://msdn.microsoft.com/en-us/library/system.int32_members.aspx) will convert the numeric string into an integer, assuming it is correctly formed:-
```auto
var pos = TextEnter.LastIndexOf(" ");
var numString = TextEnter.Substring(pos + 1);
var num = Int32.Parse(numString);
```
