aimbot.cpp
add this under your #defines: Code:

#define g3_PI 3.141592653589793238462643383279502884197169399375

then clien.cpp
add this on top: Code:

#ifndef g3_PI
#define g3_PI 3.141592653589793238462643383279502884197169399375
#endif

then find this: Code:

void HUD_PlayerMove

under: Code:

float yaw = a->angles[1] * 0.01745;

add this: Code:

switch (cvar.better_pi)
  {
  case 1:
      yaw = a->angles[1] * (3.141592653589793238462643383279502884197169399375 / 180.0);
      break;
  default:
      yaw = a->angles[1] * (g3_PI / 180.0);
  }

cvar.cpp: Code:
 
REGISTER_CVAR_INT( better_pi ,0)

cvar.h: Code:
 
int better_pi;
