[JASS] Multishot

[kawas11]

Hi. I don't kow how to create units and mvoe units like in screenshot with making them face that angle instantly.

I have once created it as i wanted but units was facing wrong direction so this was not looking good.

at this moment i got quick made jass script for that to let you help me with it.

scope MS

    globals
        private constant integer SPELL_CODE = 'A002'
        private constant integer DUMMY_CODE = 'h001'
        private constant integer AMMOUT = 7
        private constant real ANGLE_ARC = 30
    endglobals

        set a = angles[this].real[index]

Atan2 and the standard Cos and Sin functions use radians, not degrees. Try using:
private constant real ANGLE_ARC = 30 * bj_DEGTORAD

Ok, this fixed the problem with unit moving but there still is problem with unit facing.

a * bj_RADTODEG.

Creating a unit use degree.
