Unsynced Read

Here follows functions(and some global variables) that can be used to read information rewarding the game. These functions work BOTH in the unsynced environment and the synced environment.

Reading a function:
<function> (number A | string B, number C) -> nil | number, number

  • -> Text following after this shows what the function returns
  • | stands for XOR. So if you see A | B before the output sign("->") then it means that it gets either A or B as argument. If you see this after the output sign then it means that either A or B will be returned. Pay attention that ONLY one of the two will be passed/returned.
  • , is to seperate arguments/values. So A, B before the output sign means that the function gets A and B as arguments. After the output sign it means that the function returns A and B.
  • number, string, nil, boolean just indicates the type of the argument or the return value. So if it stands number A, string B before the output sign then it means that first parameter is a number and second parameter is a string. If it follows after the output sign then it means that the return value A is a number and the second is a string.
  • [] stands for "optional". If you see number A, [string B] before the output sign then it means that you have to pass argument A and if you wish you can even pass a second argument, B.
  • {..} is the indication of a table. Tables are usually returned and almost never passed as arguments. If you see {A=number, B=string} then it means that the returned value is a table that has variable A which holds a number and variable B that holds a string. If you just see {} then it just means that the table is empty.
