passing functions as arguments

[Exfyre]

how would I pass a function as an argument so that it can be called remotely?

 

[Azlier]

Well, you take a code value and use a trigger to fire it. Alternatively, if you want to allow passing arguments, you use function interfaces.

 

[Exfyre]

can you provide an example?

 

[Azlier]

library ExecuteCode

globals
    private trigger t = CreateTrigger()
endglobals

function ExecuteCode takes code c returns nothing
    call TriggerAddAction(t, c)
    call TriggerExecute(t)
    call TriggerClearActions(t)
endfunction

endlibrary

 

[Exfyre]

okay, but how would i store the code if I need to add it to a struct, since you can't have code arrays

 

[Azlier]

Well, you have a trigger as a member in the struct instead. You add the code as an action to the trigger and release the action when the struct is destroyed.

oooo >.< sneaky +rep for the help

There's also this.

globals
    string array functions
endglobals

function HelloWorld takes nothing returns nothing
    call BJDebugMsg( "Hello World" )
endfunction

function DomoSekai takes nothing returns nothing
    call BJDebugMsg( "Domo Sekai ~Kimi Unko!" )
endfunction

function BrokeBackFootmen takes nothing returns nothing
    call CreateUnit( Player(0), 'hfoo', 0, 0, 0 )
    call CreateUnit( Player(0), 'hfoo', 100, 0, 0 )
endfunction

function Actions takes nothing returns nothing
    local integer i = 0
    loop
        exitwhen i > 2
        call ExecuteFunc( functions<i> )
        set i = i + 1
    endloop
endfunction

function Init takes nothing returns nothing
    set functions[0] = &quot;HelloWorld&quot;
    set functions[1] = &quot;DomoSekai&quot;
    set functions[2] = &quot;BrokeBackFootmen&quot;
endfunction
</i>

Though it'd be easier to pass data abusing triggers.
[ljass]local integer parentKey = GetHandleId(GetTriggeringTrigger())[/ljass]

executefunc bad

 

[Jesus4Lyf]

No, there isn't that for all kinds of good reasons generally , but there's this:

function interface BasicFunction takes nothing returns nothing

globals
    BasicFunction array functions
endglobals

function HelloWorld takes nothing returns nothing
    call BJDebugMsg( "Hello World" )
endfunction

function DomoSekai takes nothing returns nothing
    call BJDebugMsg( "Domo Sekai ~Kimi Unko!" )
endfunction

function BrokeBackFootmen takes nothing returns nothing
    call CreateUnit( Player(0), 'hfoo', 0, 0, 0 )
    call CreateUnit( Player(0), 'hfoo', 100, 0, 0 )
endfunction

function Actions takes nothing returns nothing
    local integer i = 0
    loop
        exitwhen i > 2
        call functions<i>.execute()
        set i = i + 1
    endloop
endfunction

function Init takes nothing returns nothing
    set functions[0] = HelloWorld
    set functions[1] = DomoSekai
    set functions[2] = BrokeBackFootmen
endfunction</i>

And with that you can use functions with parameters. :thup:
It is not as efficient as Azlier's suggestion.

Where is the code array snippet?

 

[Jesus4Lyf]

Broken by 1.24c I'm pretty sure. :thup:
