RotateAroundAxis htlp

[raydan]

how can i do the same thing in SDK?

RotateAroundAxis, what exactly doing?

VectorRotate()? AngleVectors()?

I didn't quite understand your post so here's a link to what you are talking about.

i want to know how to implement RotateAroundAxis in c++

[MakeR]

in mathlib/vmatrix.h there are these functions:

[cpp]void MatrixFromAngles( const QAngle& vAngles, VMatrix& dst );
void MatrixRotate( VMatrix& dst, const Vector& vAxisOfRot, float angleDegrees );
void MatrixToAngles( const VMatrix& src, QAngle& vAngles );[/cpp]

Hope this helps.

QAngle eyesang(0.0f,90.0f,0.0f);
QAngle ang;
Vector f,r,u, vec;	
AngleVectors(eyesang,&f,&r,&u);
VMatrix m;
MatrixFromAngles(eyesang,m);
MatrixRotate(m,r, 270.0f);
MatrixToAngles(m, ang);
DUMP_XYZ(ang);

output is -0.000003 90.000000 -90.000000

function ftest( player, command, arguments )
   local eyeangles = Angle(0, 90, 0 ) 
   eyeangles:RotateAroundAxis(eyeangles:Right(), 270)
   Msg(tostring(eyeangles))
end 
concommand.Add("test",ftest )

output is 90.000 90.000 0.000

You would have more luck in the programming forum.
