TextField Query

Questions & Answers

Hi there,

I’ve got the following script

#pragma strict
var stringToEdit : String = "Type Code Here";

function OnGUI(){

	stringToEdit = GUI.TextField (Rect (10, 10, 200, 20), stringToEdit, 25);;
	
	if (GUI.Button (Rect(Screen.width/2,Screen.height/2,80,20), "Submit")){
	
	if(stringToEdit == "LCD TV"){
		Application.LoadLevel ("TVscene");
	}
	if(stringToEdit == "Camera"){
		Application.LoadLevel ("Camerascene");
	}
		
		}
		}

Which works great. However, if the user types in something in the textfield that isn’t specified in the code, I want some sort of error message to come up (i.e. “Error: Invalid Keyword”).
Could I achieve this with an else statement perhaps?

Anyone have any ideas?

Thanks

var StringIfError : String = “”;

function OnGUI()
{

    stringToEdit = GUI.TextField (Rect (10, 10, 200, 20), stringToEdit, 25);

    StringIfError = "";

   if(stringToEdit != "LCD TV" && stringToEdit != "Camera")
   {
      StringIfError = "Error: Invalid Keyword";
   }

    if (GUI.Button (Rect(Screen.width/2,Screen.height/2,80,20), "Submit"))
    {
        if(stringToEdit == "LCD TV")
        {
           Application.LoadLevel ("TVscene");

        }

        if(stringToEdit == "Camera")
        {
           Application.LoadLevel ("Camerascene");
 
        }

        
   }

   GUI.Label(Rect(10, 30, 100, 20), StringIfError );

}
