When you mean walls ? you mean entities or worldspawn walls?
also try zXCaptainXz code but change the movetype
PHP Code:
entity_set_int(ent, EV_INT_solid, SOLID_BBOX)
entity_set_int(ent, EV_INT_movetype, MOVETYPE_FLY);
PHP Code:
entity_set_int(ent, EV_INT_solid, SOLID_BBOX)
entity_set_int(ent, EV_INT_movetype, MOVETYPE_NOCLIP);
and remove the entity when its not within the world.
