I just started using functions and it kinda bugs me that there is a Parameter function which I have no idea how to properly use or what it's really for. Could someone give a good example of a function with Parameters? Thanks

The GetBoolean function takes two parameters, an object and a string. These are values that you can send to the function when you want to use it. Say you have an object called hat, and an attribute that flags if it is worn, "worn", you could use the function like this:

flag = GetBoolean(hat, "worn")

Using parameters means you can use the same function with another attribute of a different object.

There is a Wiki article on parameters; the way Quest handles them is typical of most programming languages.
https://en.wikipedia.org/wiki/Parameter_(computer_programming)

think 'input/output' functions, like in/for math.

Parameters/Arguments ARE your inputs, which will be used by your Function's scripting:

simpliest example of Arguments/Parameters:

<function name="adder_function" parameters="integer_number_parameter_1,integer_number_parameter_2" type="int">
  return (integer_number_parameter_1 + integer_number_parameter_2)
</function>

// scripting example:

game.sum_integer_attribute = adder_function (2,7) // the '(2,7)' are the Arguments, they match up with the Parameters
// game.sum_integer_attribute = 2 + 7 = 9

game.sum_integer_attribute = adder_function (14,8) // the '(14,8)' are the Arguments, they match up with the Parameters
// game.sum_integer_attribute = 14 + 8 = 22

game.int_num_1 = 14
game.int_num_2 = 8
game.sum_integer_attribute = adder_function (game.int_num_1,game.int_num_2) // the '(game.int_num_1,game.int_num_2)' are the Arguments, they match up with the Parameters
// game.sum_integer_attribute = 14 + 8 = 22

// -----------------

here's another simple example:

<function name="my_msg_function" parameters="message_string_parameter" type="string">
  return (message_string_parameter)
</function>

// scripting example:

game.message_string = my_msg_function ("hi")
// game.message_string = "hi"

game.msg_string = "hi"
game.message_string = my_msg_function (game.msg_string)
// game.message_string = "hi"

Ok thanks

the Arguments match up with the Parameters in terms of position:

example_function (argument_position_1,argument_position_2,etc)

<function name="example_function" parameters="parameter_position_1,parameter_position_2,etc">
  msg (parameter_position_1)
  msg (parameter_position_2)
</function>

// ----------------------

a conceptual example:

string_variable_1 = "hi"
string_variable_2 = "bye"

example_function (string_variable_1,string_variable_2)

parameter_position_1 <=== (argument_position_1) string_variable_1 <=== "hi"
parameter_position_2 <=== (argument_position_2) string_variable_2 <=== "bye"

<function name="example_function" parameters="parameter_position_1,parameter_position_2,etc">
  msg (parameter_position_1) // msg (parameter_position_1 = argument_position_1/string_variable_1 = "hi") // msg (parameter_position_1 = "hi") // msg ("hi")
  msg (parameter_position_2) // msg (parameter_position_2 = argument_position_2/string_variable_2 = "bye") // msg (parameter_position_2 = "bye") // msg ("bye")
</function>

you can name your parameters whatever you want, changing the name or keeping it the same. As, you can use the Parameters from a Function for the Arguments in a function call to another Function, keeping the other/next/new/2nd Function's Parameters the same name as the first Function's Parameters' names, or changing them to be named differently. It doesn't matter.

Parameters/Arguments are a way to use inputs within/for a Function's scripting, including transfering those inputs from Function to Function.

The Argument is the input, either a direct/literal value or as a VARIABLE, and the matching Parameter is just a Variable for that input (the input/argument is stored/saved into the parameter), which you can then use that Parameter (a Variable) within/for your Function's scripting.

I think I understood it. I will play a little bit with it until I fully understand it! Thanks
