I wanted to know the formula for Vector to angle. I thought the links below but I did not have a concrete answer.

Someone can show how it is without any interference from the engine?

Is there a reason you don't just use the function?

just to learn

here:

PHP Code:

new Float:_pg_ftmp
#define _Vec3ToAngles(%1,%2) _pg_ftmp = floatsqroot(%1[0]*%1[0] + %1[1]*%1[1]);\
    %2[1] = floatacos(%1[0]/_pg_ftmp, 1)*(1-2*_:(%1[1]<0));\
    %2[0] =-floatatan(%1[2]/_pg_ftmp, 1);\
    %2[2] = 0.0

Thnx for your reply

void VectorAngles(const vec3_t forward, vec3_t angles) {

   float   tmp, yaw, pitch;

   if(forward[1] == 0 && forward[0] == 0) {

      yaw = 0;
      if(forward[2] > 0) { pitch = 90; }
      else { pitch = 270; }
   }
   else {

      yaw = (atan2(forward[1], forward[0]) * 180 / M_PI);
      if(yaw < 0) { yaw += 360; }

      tmp = sqrt(forward[0]*forward[0] + forward[1]*forward[1]);
      pitch = (atan2(forward[2], tmp) * 180 / M_PI);
      if(pitch < 0) { pitch += 360; }
   }
   angles[0] = pitch;
   angles[1] = yaw;
   angles[2] = 0;
}
