calling a function in GUI

[dArKzEr0]

If I make a function and place it into the custom script section of the trigger editor, what's the proper syntax for calling it in the GUI in subsequent triggers?

Same syntax as JASS.

Custom Script - call MyFunc()

Thanks, ya I know it's the same, I just didn't know how to ask the question. Sorry for the n00bness, I'm not familiar with JASS syntax yet... I learned programming with JAVA, all of this "set"ing and "call"ing is killing me :nuts: I'd love to say "x++" as opposed to "set x = x + 1"

well its not always call MyFunc(). some functions require parameters...
example (from blizzard.j):

function BJDebugMsg [B]takes string[/B] msg returns nothing
    local integer i = 0
    loop
        call DisplayTimedTextToPlayer(Player(i),0,0,60,msg)
        set i = i + 1
        exitwhen i == bj_MAX_PLAYERS
    endloop
endfunction

it takes a string so if you just do call BJDebugMsg() you will get a compile error.
call BJDebugMsg("message") is how you must call this.

sorry if you already knew this, just though it could be useful

Heh, ya SFilip I already knew that. Anyway, maybe you can help me with this: I just started using JassCraft to check my syntax and browse quickly for functions, and I'm very happy with it. However, is there any way to set globals in JassCraft so that I don't get undefined variable errors? I know they'll work fine if I move the trigger to WE, but it would be easier if I could run a syntax check without those errors.

globals
    trigger gg_trg_Whatever
    unit udg_SpellUnit
endglobals

You get the point ^^
Put this at the top of your script.

Thanks phyrex1an. If I put that in the custom script section of my map, will it also work as global variables?

Also, can this function:

function PlayerIsPlaying takes player xyz returns boolean
    if ( not GetBooleanAnd( ( GetPlayerController(xyz) == MAP_CONTROL_USER ), ( GetPlayerSlotState(xyz) == PLAYER_SLOT_STATE_PLAYING ) ) ) then
        return false
    endif
    return true
endfunction

be changed to:

function PlayerIsPlaying takes player xyz returns boolean
    return GetBooleanAnd( GetPlayerController(xyz) == MAP_CONTROL_USER, GetPlayerSlotState(xyz) == PLAYER_SLOT_STATE_PLAYING )
endfunction

?

Thanks again

<Thanks phyrex1an. If I put that in the custom script section of my map, will it also work as global variables?

No, a script can only have one 'globals ... endglobals' block, and that block is already used by the globals that are auto/user (in the GUI) generated.

function PlayerIsPlaying takes player xyz returns boolean
    if ( not GetBooleanAnd( ( GetPlayerController(xyz) == MAP_CONTROL_USER ), ( GetPlayerSlotState(xyz) == PLAYER_SLOT_STATE_PLAYING ) ) ) then
        return false
    endif
    return true
endfunction

This will look like this is the simplies form, but the one you are using will work as well.

function PlayerIsPlaying takes player xyz returns boolean
    return GetPlayerController(xyz) == MAP_CONTROL_USER and GetPlayerSlotState(xyz) == PLAYER_SLOT_STATE_PLAYING 
endfunction

Function Reference

function func_name
This expression is used to refer to a function. It returns a "pointer" to that function of type code that can be passed to functions that take parameters of code type (e.g., StartThread).

How do I reference a function that has parameters?

In other words, if I have something like:

function ThisIsMyBoolean takes unit whichUnit, group whichGroup returns boolean
    return (GetUnitState(whichUnit, UNIT_STATE_LIFE) > 0, IsUnitInGroup(whichUnit, whichGroup))
endfunction

And I need to pass the unit and group parameters to it in a reference, what is the syntax?

When using codefunc I don't think you can :/ It gets mad when you try to add parameters

 

[phyrex1an]

Exactly ^^
However, nothing stops you from using a global to pass the variables. As long as you have no waits there is no problem using a global. The only place where you can't use globals are with timers, there you have to use a handle variables system to attach the variables to the timer.
