Hola amigos!

I programed a gun entity on next way:

entity gun0
{
type = <el_revolver.mdl>;
//ambient = -30;
pan=90;
x= 5;
scale_x=2;
scale_y=2;
scale_z=2;
layer=1;
y= 3;
z= 0;
ammo=0;
numbergun=1;
recargar=1;
}


I want to make it passable. what is the code i have to add.

And other thing: Why the color of that gun entity ever is the same? When i go in a dark room the shadows dont affect my entity gun , it looks every time iluminated.

Thanks!
