I also tried the nullvector like this:
if (t_shooter_weapon == 1) ent_create(weapon1_mdl, nullvector, pistol);
and like this:
if (t_shooter_weapon == 1) ent_create(t_shooter_weapon1_mdl, nullvector, pistol);
its no good, most of the time it gives me this error:
"weapon1_mdl" undeclared indentifier
so does for t_shooter_weapon1_mdl same error
