Loops

[defskull]

Hi all, greetings from defskull
I'm gonna be straight to point
My problem is that I don't know how to calculate for every loop, new degree is formed and my arrow would be at that new formed degree location
Basically, I'm trying to create a Multi Shot-like ability
I'm gonna fire 4 arrows, which is 22.50 degree per arrow, covering in 90 degrees area
How to do it ?
I keep failing in firing those arrows, all end up in the same degree... (sucks hard)
Can someone edit my test map ?
(Don't bother to remove/comment on the 'Wait' action as I used it just for testing the arrows' location/degrees)

example:

• For each (Integer A) from 1 to X, do (Actions)
• Loop - Actions
  • Set TempPoint[1] = (Point offset by X towards (Y x (Real((Integer A))) degrees)

Please try and download my test map and edit it and post it back here
I can't understand a thing @.@
If that's too hard, naah, I'll think it myself..

oh i haven't read the whole post ~.~ a moment and i send it

JASS solution:

local real start = GetUnitFacing(GetTriggerUnit())
local real angle = 0.0
local real yourAngle
if (start < 45) then
    set start = 360 - start - 45
else
    set start = start - 45
endif
loop
    exitwhen (angle > 90)
    if (start + angle > 360) then
        set start = start - 360
    endif
    set yourAngle = start + angle
    // Do things with your angle
    set angle = angle + 22.5
endloop

well because of the even number of arrows it's a bit different but here you are an example
