direction of velocity script

[Master_Chief 0]

I need an equation that will find the the direction in degrees that the object is travelling based on its velocity. I don't want the direction that the object itself is facing though. Any help? I am trying to make a slideslip script for a car.

Maybe something like this:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_obj = _this select 0

_velX = velocity _obj select 0

_velY = velocity _obj select 1

_dir = _velY Atan2 _velX

hint format ["Direction of _obj: %1",_dir]

exit

no warranty

Easy enough to do with some trig:

_vx = velocity _car select 0

_vy = velocity _car select 1

_dir = asin (_vy / sqrt(_vx^2 + _vy^2))

I might be mistaken on that, as I'm a bit tired atm.

It is really the same, isn't it?

Whoops, guess you posted while I was typing . Yeah, mathematically it is the same, but [b.B.S.] T_D's solution is better, since it uses less commands and thus less cpu power.

one minor thing, I think it's _velX Atan2 _velY. Also if you want to convert this to a normal 0-360 just do it like this:

_velX = (velocity _obj select 0)

_velY = (velocity _obj select 1)

_dir = _velX Atan2 _velY

?_dir < 0 : _dir = 360 + _dir

It really doesn't matter if you do that since the result is the same, just in positives, rather than negatives.
