[JASS] "code" as parameter....

Sharingan	JASS: TimerStart(timer whichTimer, real timeout, boolean periodic, code handlerFunc) Somehow, i can't use functions with parameters as the "code-parameter"... like: call TimerStart(timer, 0.1, true, function bla(unit)) ... it would have to be : call TimerStart(timer, 0.1, true, function bla) ...(a function without parameter) Am i doing something wrong?

No, 'code' variable means it does not pass anything into the function.
If you want to pass something into the function you have to use the return bug and a gamecache

EDIT: I decided to show you how to do it, this is how you can do it:

This requires a gamecache called GC (or udg_GC in Jass)

JASS:

function GameCache takes nothing returns gamecache
    if(udg_GC == null) then
        call FlushGameCache(InitGameCache("GC"))
        set udg_GC = InitGameCache("GC")
    endif
    return udg_GC
endfunction

function H2I takes handle H returns integer
    return H
    return 0
endfunction

function I2Unit takes integer I returns unit
    return I
    return null
endfunction

function DoSomeAction takes nothing returns nothing
    local unit StoredUnit = I2Unit(GetStoredInteger(GameCache(), I2S(H2I(t)), "SomeDescriptionOrLabel"))
    // DO SOME ACTIONS
endfunction

function StartTimerNStuff takes unit whichUnit returns nothing
    local timer t = CreateTimer()
    call StoreInteger(GameCache(), I2S(H2I(t)), "SomeDescriptionOrLabel", H2I(whichUnit))
    call TimerStart(t, 10., flase, function DoSomeAction)
endfunction

EDITED: I forgot the () after CreateTimer

Chuckle_Brother	a "code" variable is what is created when you go: function FUNCTIONNAME its used by timers, triggeraction additions and some other random things.

Sharingan	Hmm, what i wanted to do is actually to implement "GetTriggerPlayer" into the "trigger_action" function, in which i have that JASS: call TimerStart(t, 10., flase, function DoSomeAction) . I can't write GetTriggerPlayer() into "DoSomeAction", since that function is "outside" of the event trigger...

PipeDream	Yep, that's what TideHunter's post solves. You use the timer's handle as a unique ID to index the game cache, then store whatever you need in there.

Sharingan	Hmm, now i see, thanks a lot!

In your condition, it would be:

JASS:

function GameCache takes nothing returns gamecache
    if(udg_GC == null) then
        call FlushGameCache(InitGameCache("GC"))
        set udg_GC = InitGameCache("GC")
    endif
    return udg_GC
endfunction

function H2I takes handle H returns integer
    return H
    return 0
endfunction

function I2Unit takes integer I returns unit
    return I
    return null
endfunction

function DoSomeAction takes nothing returns nothing
    local unit StoredUnit = I2Unit(GetStoredInteger(GameCache(), I2S(H2I(t)), "SomeDescriptionOrLabel"))
    // StoredUnit is now triggering unit from StartTimerNStuff function
endfunction

function StartTimerNStuff takes nothing returns nothing
    local timer t = CreateTimer()
    call StoreInteger(GameCache(), I2S(H2I(t)), "SomeDescriptionOrLabel", H2I(GetTriggerUnit()))
    call TimerStart(t, 10., flase, function DoSomeAction)
endfunction
