JASS: Introduction

[Rad]

Um maybe im getting an error, about 3/4 of those code fields are empty, and 2 are all messed up and stretched out of the box. I restarted my browser, am I the only one with this problem in this thread?

Man this is very nice, one time when i feel like learning JASS, i will use this

thanks for not explaining jass

sry man, but when people make jass tutorials, what ive always looked for first thing is HOW the initial function lines work, WHAT the arguements do-just saying that they are called arguements is barely more then gibberish.

 

[The_Prophet]

this tutorial is anything but a " GENERIC USELESS TUTORIAL" This is the same tutorial i learned from, only on wc3jass.com, and i would consider it the best jass tutorial on the net. Especially for someone new to programing.

 

[uberfoop]

fine-maybe ill take your word for it and read the entire article and then decide if it makes sense...

He explains the arguments in there, just not in the beginning.

You are confusing a JASS tutorial with an explanation of each native function blizzard has added. blerg wc3jass.com jass.sourceforge.net/doc/ for that stuff .

You can't learn to use a blizzard's function if you didn't learn how to use JASS before doing that.

very nice tutorial

 

[uberfoop]

5 Stars! Go vex!

I love how it has to be a '5 star bump' by helper rather than just a bump
Just felt like saying that

 

[Sooda]

Very good I got new knowledge from it ! BUMP also Sometimes it goes way abstract but what isn' t abstract (The power of symbols- 0 to 9.) ?

5 star bumps <3

Nice tutorial! Probably one of the easiest tutorial to learn ^^

 

[Vulcansurge]

Its been a few years since you wrote this tutorial, and people are still learning from it. Great work! Five stars from me!

lal great tut very nice, but most of it explains how to display text in diffrent ways^^ and how to you the " * , - , + , / " anyways really nice

readed whole thing^^

I just have one problem when you talk about global:

function Msg takes string s returns nothing
call DisplayTextToForce( GetPlayersAll(), s )
endfunction

function AddSubstract takes integer a, integer b returns nothing
set udg_r1=a+b
set udg_r2=a-b
endfunction

function Trig_JASS_test_Actions takes nothing returns nothing
local integer a=14
local integer b=56
call AddSubstract takes(a,b)
call Msg("a= "+I2S(a))
call Msg("b= "+I2S(b))
call Msg("The Addition is "+I2S(udg_r1))
call Msg("The Substraction is "+I2S(udg_r2))
endfunction

The red line always get me an error and I can't find out why its wrong. I have tried to re-type everything, and it didn't work, so I copy-pasted everything and it still isn't working. Can I get some help please?

By the way, excellent tutorial, first one I find which is really helping me.

You don't need the "takes" in there; the "takes" keyword is only used in the function name.

Thus, you'd call it like this:

call AddSubtract(a,b)

Thanks a lot man, it works now
Would be a good idea to correct it in the tutorial.

Ps: How do I post a quick reply? The box is all grayish and it says ''click one of the quick reply icon in the post above'' but I just can't find the quick reply icon.

 

[Pyrogasm]

It's the second button to the right of the "quote" button. When you press it, it higlights and then brings you to the quick reply box.

When i click the link for the answers to the challenge, it just doesn't work. It brings me to wc3campaigns.com or something like that, and there is no answer around there.

Edit: I found the answer by myself now, but would still be useful to have the answers for the future challenge. I'm proud i got this one

And about the loop part, instead of making two locals, would it work to do:

function Trig_JASS_test_Actions takes nothing returns nothing
local integer a=GetRandomInt(1,5)
loop
call Msg("a= "+I2S(a))
exitwhen a==0
call Msg("Hello")
set a=a-1
endloop
endfunction

Seems like less trouble to me, would it cause leaks or something? Or is it fine?

I'm lost

Calling a function

For calling functions we use:

call <Function Name>(Argument1,Argument2,...,ArgumentN)

In cases where the function takes no arguments, it is just:

call <Function Name>()

Functions can call other functions, AS LONG AS the other functions are written ABOVE the function in the map script. If a function is above other function in the same 'trigger', the other function may call it. But there is no safe way to make sure the contents of a custom trigger will be added to the map script before the contents of another trigger.

The Frozen Throne editor, comes with a "Custom Script section" feature, When you are at the trigger editor, click on the map's name, and you will be able to see the Custom Script section, that's a place for functions. The contents of the Custom Script section are added to the map script before the contents of every trigger.

An example wouldn't hurt:

Code:

function Msg takes string s returns nothing
    call DisplayTextToForce( GetPlayersAll(), s )
endfunction

function ShowMessage takes nothing returns nothing
    call Msg("This is a message!")
endfunction

function ShowSum takes integer a, integer b returns nothing
 local integer r=a+b
    call Msg("r= "+I2S(r))
endfunction

function Trig_JASS_test_Actions takes nothing returns nothing
   call ShowMessage()
   call ShowSum(33,45)
endfunction

The result will be:

This is a message!
r = 78

I'm trying to learn, but I can't figure out that "s" letter at the beginning of the code.

function Msg takes string s returns nothing
    call DisplayTextToForce( GetPlayersAll(), [COLOR="Red"]s[/COLOR] )
endfunction

It gives me a bunch of errors

Can someone explain, or is it the wrong place to ask?
