Ok, so basically I am making a game engine, and am having it so it reads from a code file at runtime. This is a short snippet that is causing the problem:
(varList is a string, varArray is an array, I am splitting spaces to read the code file, so str is the string after the first space, the cases is the word before the first space)
case "var":
varList = varList + str + "|";
varArray = varList.ToString().Split("|"[0]);
case "getkey":
var varIndex : int = 999;
var error : boolean = false;
var isDone : boolean = false;
for (var iCount : int = 0; iCount < varArray.Length; iCount++) {
if (varArray[iCount] == str && isSub && error == false && isDone == false) {
varIndex = iCount;
error = false;
isDone = true;
}
}
if (error || isDone == false || varIndex == 999) {
print("Variable, '" + str + "' not found!");
} else {
var key;
while (key == "") {
key = Input.anyKeyDown;
}
print("Key pressed : " + key.ToString());
}
break;
sorry, formatting a bit messed up, but basically its throwing this error repetitively:
NullReferenceExceptioon: Object reference not set to instance of an object
Boo.Lang.Runtime>RuntimeServices.InvokeBinaryOperator (System.String operatorName, System.Object lhs System.Object rhs)
Referring to the line of code: varList = varList + str + “|”;
