Trying to make opposite GetXYInFrontOfPlayer - get Rotation - PoWerZ - 20.09.2009

I'm trying to make the opposite of GetXYInFrontOfPlayer.
I have 4 floats, 2 of the player XY and 2 of the XY Infront of the player view and i want to get the Rotation of the player.(Player is just example,it can be object vehicle and etc..).
I subtract each X from other X and same with Y,make them positive(absolute value of a float[EX:from -1.3 to 1.3]) and then i sum them and get the distance.
so far we have player pos,xyinfrontofplayer and distance.
then i want to make some equation;
Orginial:
Код:
X +=(Distance*floatsin(-A,degrees)); //X infront player after some Distance
Y +=(Distance*floatcos(-A,degrees)); //Y infront player after some Distance
Can be Also.
Код:
X1+(Distance*floatsin(-A,degrees)) = X2
Y1+(Distance*floatcos(-A,degrees)) = Y2
(X1 = PlayerPos X,X2 = X infront of player view)
(Y1 = PlayerPos Y,Y2 = X infront of player view)

I want to get the Rotation of the player so i remake the equation To this:
Код:
floatsin(-A,degrees) = (X2-X1)/Distance
floatcos(-A,degrees) = (Y2-Y1)/Distance
EX:
X1 = 250.5;
Y1 = -430.625;
X2 = 246.741226;
Y2 = -429.256927;
Distance = floatabs(X2-X1)+floatabs(Y2-Y1);
Код:
floatsin(-A,degrees) = (246.741226-250.5)/Distance
floatcos(-A,degrees) = (-429.256927-(-430.625))/Distance
from this part I don't know how to continue the equation and how to place the sin(or cos)
calculation which will give me the Float of the Rotation.

Is that what your trying to make?

No,
2 things:
1)I'm trying to set float,by caculating variables.
2)Player can be an example,I'm just trying to set his(EX:its - for objects) facing angle by checking his xy position and the xy position SOMEWHERE.
EX:Player/object is at LV and i do command which change his float:angle to look on some XY.(I don't know the float angle and trying to get it by an equation)

Again,
this isn't what i'm asking for,
I want to set float:angle to player/object by checking their xy and the target xy,
and AGAIN EX:Me and my friend in area51 he is somewhere,I get his xy and my xy
and i want set my angle to the side he comes from.(i don't want to make any marker or something like that)
