HELP! On my single-player world (creative) I am making a gold farm that I might make on EMC if it is successful. Now, here is where I am stuck: I don't know how to make the pigmen from staying on the portals to falling down! They are not voluntarily doing it, so how can I make them? Please comment, but only helpful ones! ^Note: the main walls aren't up so do not say 'oh, your walls aren't built' or unhelpful comments.^^^
Portals generally are supposed to have a 1 block width, not several portals clumped together. When it's just 1 block width the pigment end up pushing each other off or the spawn falling off
