need a bit of help understanding how this works, exactly

[Sui-cookie]

in:

function Trig_Untitled_Trigger_004_Func002C takes nothing returns boolean
    if ( not ( GetPlayerController(Player(0)) == MAP_CONTROL_USER ) ) then
        return false
    endif
    return true
endfunction

function Trig_Untitled_Trigger_004_Actions takes nothing returns nothing
    if ( Trig_Untitled_Trigger_004_Func002C() ) then
        call DisplayTextToForce( GetPlayersAll(), "p?" )
    else
        call DisplayTextToForce( GetPlayersAll(), "C?" )
    endif
endfunction

//===========================================================================
function InitTrig_Untitled_Trigger_004 takes nothing returns nothing
    set gg_trg_Untitled_Trigger_004 = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Untitled_Trigger_004, function Trig_Untitled_Trigger_004_Actions )
endfunction

It splits the possibilities by the boolean returned in
"Trig_Untitled_Trigger_004_Func002C"
but in the next function, it uses the if:

    if ( Trig_Untitled_Trigger_004_Func002C() ) then

i don't quite understand that line... how is it determining which return it came up with?

 

[Weep]

First, remember that converted GUI is often poorly-constructed as far as code is concerned.

It works because the function "Trig_Untitled_Trigger_004_Func002C" returns a boolean, meaning that the result of that function is a boolean, ie. you can think of that function as if it is a boolean value that changes based on its calculation. To say "if Trig_Untitled_Trigger_004_Func002C() then" means to do the first part of the "if" when that function returns true (which is when Player(0) is a user).

When writing it yourself, having a separate function is typically unnecessary for if-then statements. You could rewrite it like this:

function Trig_Untitled_Trigger_004_Actions takes nothing returns nothing
    if GetPlayerController(Player(0)) == MAP_CONTROL_USER then
        call DisplayTextToForce( GetPlayersAll(), "p?" )
    else
        call DisplayTextToForce( GetPlayersAll(), "C?" )
    endif
endfunction

//===========================================================================
function InitTrig_Untitled_Trigger_004 takes nothing returns nothing
    set gg_trg_Untitled_Trigger_004 = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Untitled_Trigger_004, function Trig_Untitled_Trigger_004_Actions )
endfunction
