The Very Beginning of Scripting

[H3DG3H0G]

Hello guys! Today i'm here to ask a simple question which i have been looking for everywhere.  Why should we put something inside of () after function? I mean function simpleTask(ammo, killer, bodypart, money). And if it's like an extension how many of them exist? Is there any list of things we should put inside of () after function and usage of them?

The '()' after a function is a parameter list. Parameters are basically variables, which are used when you need to pass data through to a function. You can have as many parameters as you like.

 

Here's a small example.

function add(x, y) --define your parameters, in this example they are "x" and "y"
	local sum = x + y
	return sum
end

local myVar = add(1, 3) --we pass through 2 arguments into the "x" and "y" slots of the add() function. x = 1, y = 3

In the example above, "myVar" would now contain the value "4". Once we have passed the arguments through to the add() function, we can refer to them as x and y thereon.

In this example, it's useful because we can keep using the add() function, but passing new values through each time it is called.

Hope this makes sense, anything else just ask.

Thank you!

and those parameters change when you change the event of the function. (When there's an event called to directly trigger the function)

One more thing, if the second argument or parameters is 'ammo' then it would always be 'ammo' no matter what you call it. So even if you called the second parameter 'killer', killer will be the 'ammo' parameter and not the 'killer' parameter. (Idk, how clear I was here.)

if you need any scripting help you should go to this link https://wiki.multitheftauto.com/ for a proper understanding on how we pass Parameter in Mta functions
