Grid to angle?

[heedicalking]

How would I turn a normalized vector into an angle? I am trying to rotate players using eulertoaxis() and found out that doing
setTransform(%obj.getposition() SPC Eulertoaxis("0 0" SPC %rot)) where rot seems to be 360 degree based. (0 is north, 90 is west, 180 is south, 270 is east, 360 is north again)
What I am trying to do is make players rotate on their Z axis to face a location (lets say a brick). I could easily use vectorsub for projectiles but that doesn't seem to work with what I am trying to do with players. help?

So you want the angle in radians, not degrees?

[Kalphiter]

Players only have one axis of rotation, unless they're tumbling.

i guess. i want to convert the sort of grid based thing into a 360 based thing

example. the player is standing at that point. I want to make him turn on his Z to face 0,0.
setTransform(%obj.getposition() SPC Eulertoaxis("0 0" SPC ?))
i need to figure out the ? variable so he faces 0,0

You have to do some trig

Here's enough to get you started
%dif = vectorSub(%pos1,%pos2);
%rad = mATan(getWord(%dif,1),getWord(%dif,0));
%degrees = mRadToDeg(%rad) + %quadrantCompensation;

forgot to define %quadrantcompensation?

I really have no idea why this solution hasn't already come up, but...

Code: (Code that turns an %obj to face a given %targ) [Select]

function turnTo(%obj, %targ)
{
   %pos = %obj.getPosition();
   %diff = vectorSub(%targ.getPosition(), %pos);
   %ang = mAtan(getWord(%diff, 0), getWord(%diff, 1));
   %obj.setTransform(%pos@" 0 0 1 "@%ang);
}
