Jass Question

[mems]

Is it possible to call a function defined in another trigger?
- I want to make some functions and i want to call them whenever i need in different triggers they will all take and return variables is it possible?

What is the syntax of a function that retuns a unit variable?

TY for helps

Define it in the common Custom Script Code.
A function is defined as follow:
function func_name takes nothing returns nothing

If you want to take some params and return a value, define it like this:
function func_name takes param_type param_name returns return_type

A type could be integer, real, string, handle, unit, location...
Have a look to a JASS tutorial for deeper knowledgement.

You are looking for something like this:
function myFunction takes nothing returns unit

You can only call functions that is above the calling function. (custom script section is above the user defined triggers script)

It is always possible to call functions that doesnt "take" something with
call ExecuteFunc("Func_Name")
That executes a funtion by its name as a string (inside "") in a new thread. And there is no need for the function to be above the calling one. (since the calling isnt happening in the function)

And "guidline" is that trigger that is located over a another trigger has there script over the "another trigger", after you have saved the map and reopened it.

New triggers is always at the end of the script list. But is redirected (or something) after a reopening.

As xPheRe says a function used in more than one trigger is best to have in the custom script. Then you dont have to think about trigger order.



When I reading this for a last check I cant even understand what I am writing... hope you understand it .

- i unedrstood that i will call my functions if they take something when ever i want it deos not matter where they are defined. and custom functions will be called like that
if i send a string to them;
call myfunction("string")
if i sen d a variable;
call myFunction(myVar)

- But to call functions that are takes nothing and return nothin i must define them before any trigger

is it right?

In the Trigger Editor, you see the name of your map, then all the categories and the triggers inside each.
Now, if you click on the name of your map, an empty space will show up,
with the following comment:
" Enter map-specific custom script code below. This text will be included in the map script after variables are declared and before any trigger code. "

That's just the perfect place

It is the other way around. Functions that takes or returns something is best to have in the custom script. Functions that "halts" the execution function(the execution function waits unit the execution is done) is best to have in the custom script.

Functions that doesnt take or returns something and it doesnt care if the is done before or after the calling function can be anywhere in the trigger code and executet with "call ExecuteFunc()".
Since there isnt alot of functions like this... Place all functions that is used by different triggers in the custom script.

Since I feel that the only thing I have done in this thread is to complicate things id like to point out some JASS tuturials:
http://www.wc3jass.com/viewtopic.php?t=2039 Introduction to JASS.

Other tutorials with different difficulty ( :banghead: )

Is there no JASS tutorial at TH somewhere?

I didn't know about www.wc3jass.com, it looks like candy for me
