Can I pass local variable values to other functions?

Pretty self-explanatory title.

Can I pass local variable values to other functions?

 

[Rainther]

Not really. Unless you mean sending it like:

local real LawL = 600
call CustomFunction(LawL)

local real LawL = 600
call CustomFunction(LawL)

What I want to do is pick all units owned by player 5 and give shared vision of those units to the owner of the triggering unit (which is an array variable).

And you can't do all of this in one function?

You could set all of them to a unit group instead.

Sending arrays through functions demands structs if I'm not mistaken.

No I have 2 functions:

call GroupEnumUnitsOfPlayer(TEMPGROUP, Player(11), Condition(function SharedVision))

Which calls this function:

private function SharedVision takes nothing returns boolean
    local unit u = GetFilterUnit()
    local player p = GetOwningPlayer(u)
    local player ally = GetOwningPlayer(HERO[pid]) //pid NOT A LOCAL. GIVES ERRORS.
    local integer i = 0
    
    if IsPlayerAlly(p, ally) then
        call UnitShareVision(u, ally, true)
    endif
        
    set u = null
    return false
endfunction

I'm not sure how much you can do in filter functions, I usually take all units and handle them from an unit group.

What do you mean?
Using "ForGroup()"?

 

[T.s.e]

Or a FirstOfGroup() loop.

A FirstofGroup() loop would be an easy way if you're uncertain in how to pass whatever variables you need to pass. Something like this:

private function True takes nothing returns boolean
    return true
endfunction

private function Actons takes nothing returns nothing
    local group g = CreateGroup()
    local unit u
    
    call GroupEnumUnitsOfPlayer(g, Player(4), Filter(function True))
    loop
        set u = FirstOfGroup(g)
        exitwhen u == null
        //Do whatever is to be done in your filterfunction
    endloop
endfunction

    endloop

Don't I need to remove the unit from the group or something?

 

[Larcenist]

That is done at the end of the loop. Instead of your regular "set i = i + 1" or something. Just remember to add it outside the filter ifs.

Do I still have to clear/destroy/remove the group?

 

[Larcenist]

Clear, no. Destroy, yes. Unless you're using a global group that is.
