Advanced JASS Tutorials?

[storyyeller]

I have a bit of experience with VB6 and C++ and I think I've got the basics of JASS down. But I wondering if there were any good places to learn about more advanced things in JASS like memory leaks, gamecache, threads, etc.


Also, what are the most useful programs for working with JASS? I've been using JASS Craft, but while it's pretty good, it still leaves some things to be desired.

Go and dissect dota.

[storyyeller]

Well I have been looking at other people's triggers, although I haven't looked at DOTA yet

But anyway, looking at the the source only tells you "what", not "why". It won't help you much if you don't really understand the code

[Ozzapoo]

Yes it does..And you need to look to understand. So look and look and look and then you will understand and then you will know the why as well as the what and also how

If you don't understand a thing, make JassCraft tell you what it does. Find it in the Native List on the right, and click on it. It'll display what it does in the bottom box. It'll only tell you about things like PlayerSetState, however, not things like "else" or an entire trigger.

But for natives, it only displays the prototype (I assume the actual logic of the natives is hardcoded into the game)

For example, when I look up ExecuteFunc, all I see is

Code: Select all

native ExecuteFunc          takes string funcName returns nothing

That doesn't really clarify whether code like this is acceptable or not. If foo is called, do the functions execute simulatenously or in sequence? Which one goes first? Or is there an error?

Code: Select all

globals
integer i
integer j
endglobals

function foo takes nothing returns nothing
set i=0
set j=0
call ExecuteFunc("bar")
loop
   exitwhen i==1
   set j=j+1
endloop
endfunction

function bar takes nothing returns nothing
//do stuff here
set i=1
endfunction

[Ozzapoo]

Then go and try it?

[Risen]

Code: Select all

native ExecuteFunc          takes string funcName returns nothing

I think he's wanting to know if there's a way to show how it executes the code "ExecuteFunc()".

[patrick-the-bomb]

Doesn't it always execute in sequence? I was reading up on JASS, and I think it said that. Lol. It was at like 1 o'clock

Trail and error is good way to learn ...as well as a lot of testing.

ExecuteFunc can call functions that are ahead OR after the function that it's called from.
Normal calling can only reference functions that occur ahead of the function that calls it.

Using ExecuteFunc will also open a new thread, but the ExecuteFunc function called will occur before the code after ExecuteFunc.

Code: Select all

function Func1 takes nothing returns nothing
I happen first
endfunction

function Func2 takes nothing returns nothing
call ExecuteFunc("Func1")
I happen second
endfunction

This means that if I have "TriggerSleepAction(#)" (aka wait/sleep) in my Func1, Func2 will finish first. Otherwise, if I just call Func1 ( call Func1() ), Func2 will resume when Func1 is finished.
