function array?

fugly	I was wondering... is it possible to create an array of functions, or something of the sorts? or give a function a numerical value or something?

jmoritz	You cannot create function arrays like you create other arrays. There are a few alternatives (untested). 1. Create a string array and put the name of a function in the array, call the function using ExecuteFunc(funcnames[i]). You can only call takes nothing returns nothing functions in this way. 2. Create a boolexpr array. You can only call takes nothing returns boolean functions this way.

fugly	hmmm interesting... wouldn't quotations be needed for the string take? (since boolexpr are above my comprehension edit: it onlys accepts it like so Code: call ExecuteFunc("udg_HeroName[GetForLoopIntegerA()]") but then wouldn't the func name have to also be in quotations? is that possible?

1st question - WHY?!

ok, you could -- heres one way:
have a function that is the array and just index them

Code:

//ex:

function function_0 takes nothing returns nothing
//code here
endfunction

function function_1 takes nothing returns nothing
//code here
endfunction

function IamAfuncARRAY takes integer HelloWorld12 returns nothing

if (HelloWorld12 = 0) then
call function_0()
elseif (HelloWorld12 = 1) then
call function_1()
endif

endfunction

//---------

fugly	the thing is though that i wanna bypass the if/then/else cause there would be 4 of them going off every .3 secs for 5 players. i wanna see if there is a better way around it, and an array would do it

AIAndy	If udg_HeroName is a string array, then it should be accepted without the quotation marks around it. The way you wrote it he would try to execute a function with the name udg_HeroName[GetForLoopIntegerA()] (without looking up the value of that variable) which of course does not exist.

just call the function directly then, i dont see how an if-then can be "bypassed" by using an array of functs.

AIAndy	Of course that is possible with ExecuteFunc. That native takes a string and executes the function with the name passed to it. And since the passed string can be a part of a string array (or even read from gamecache), you can avoid ifs with that.

Code:

string array functionnames

set functionnames[0] = "foo"
set functionnames[1] = "bar"

function foo takes nothing returns nothing
  call DisplayText("In foo")
endfunction
function bar takes nothing returns nothing
  call DisplayText("In bar")
endfunction

function mytriggerorwhatever takes nothing returns nothing
  call ExecuteFunc(functionnames[GetUnitUserData(GetKilledUnit())])
endfunction

If a unit dies, it will display "In Foo" if the unit user data is set to 0, "In bar" if it is set to 1.

simple
the variable is an integer. what ever that integer is you run the corresponding function. Instead of doing an if/than/else of every possibity that the variable could equal.

also the editor won't accept this

Code:

call ExecuteFunc(udg_HeroName[GetForLoopIntegerA()])

because it expected a name :(

Narwanza	Are you sure udg_HeroName is a string variable?

actually its not, why you may ask? simple, i named it HeroLockName... some 1 shoot me, for the good of the human species

edit: damnit, still not working

jmoritz	GetForLoopIndexA not GetForLoopIntegerA
