I have decided to create a tutorial on Jass for non-programmers.
What's left, except writing the tutorial, is to decide on the
exact content. Please help me to do this by answering this poll.

Thank you!

Well, since you asked for it, we will begin with creating the
well-known Hello World program, trigger version.

The purpose of this lesson is that WC shall print "Hello, World!"
when it starts the used map. This is done by creating a trigger
which runs on map initialisation, which you should know already
since you are supposed to know a few things about triggers. ;)

I suggest that you start up your WE and start with creating
this trigger the normal (gui) way. When you are done with that
select you trigger, open the file-menu and choose "Convert to
custom text". It will ask you if you are really sure, and you will
happily answer Yes! When you've done that please post your
code here and I'll explain what the code means. Before you
post your code you should also make sure that it does what
it is supposed to, so save your map and try it.

Well, maybe some of you are to shy to post your code... so I'll
post 3 examples doing the same thing myself.

Pretty much produced by the WE (shows text for 30sec):

Code:

function Trig_Hello3_Actions takes nothing returns nothing
    call DisplayTimedTextToForce( GetPlayersAll(), 30, "Hello, World!" )
endfunction

//===========================================================================
function InitTrig_Hello3 takes nothing returns nothing
    set gg_trg_Hello3 = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Hello3, function Trig_Hello3_Actions )
endfunction

Another way to display text to user:

Code:

function HelloWorld takes nothing returns nothing
    call DisplayTextToPlayer(GetLocalPlayer(), 0, 0, "Hello, World!")
endfunction

//===========================================================================
function InitTrig_HelloWorld takes nothing returns nothing
    set gg_trg_HelloWorld = CreateTrigger(  )
    call TriggerAddAction( gg_trg_HelloWorld, function HelloWorld )
endfunction

And last, my favourite (shown for an hour):

Code:

function InitTrig_Hello2 takes nothing returns nothing
    call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 3600, "Hello, World!")
endfunction

Any thoughts or questions on any of the three code examples?
