[JASS] Variable index in array element asssignment

[Ext3rmin4tor]

Is it possible to use a variable index when using the set array function to assign a value to an array cell? For example:

	local integer i = 0
	loop
		exitwhen(i == 10)
		set element[i] = //something
	endloop

Yes, no problem with that.

You could even make something like that

set u[ int[i] ] = lastUnit

yes, but you are lacking one thing:

set i = i + 1

you have to do the increment yourself, so it looks like:

local integer i = 0
loop
    set element[i] = ...
    exitwhen i == 10
    set i = i + 1
endloop

also be vary that the game leaves the loop at point of exitwhen so if you want the element's index 10 you need to either make the exitwhen i == 11 or move element assigment above exitwhen

I know thanks, it's like a while-do. No problem with that. I just wanted to know if you could use a variable index, because for example some stuff you can do in programming languages are not allowed in plain JASS, such as passing an array as function argument.

it can be normal while, it depends on where you put the exitwhen
dont forget, this is scripting language and in blizzard they are too lazy to implement around anything

Indeed, they are. And as an example, Trackables which is left unfinished. I am sure that pro programmers in this site could make unofficial patch better 1000 times than Blizzard ones and could add much more useful stuff to WC3.
