I am trying to shoot fireball. the thing is , when i lookup and shoot. the fireball is off aim. i save the angles of the ''look-around'' and the players coord. then this code: weaponx += sin(weaponyaw*piover180);// * ( 1.0f );// * COS[(int)(m_vheading*10.0f)]; weaponz -= cos(weaponyaw*piover180);// * ( 1.0f );// * COS[(int)(m_vheading*10.0f)]; weapony -= sin((weaponpitch)*piover180);// * ( 2.0f );// + cos(weaponpitch*piover180));//0.5; glTranslatef(weaponx,weapony,weaponz); i need a better calculation for weapony. Does anyone know? Thanks, Bobby
