On the PS Vita release of Terraria, I cannot fight the wall of flesh (fairly). I have built a long bridge across the underworld, but no matter where I drop the doll, the Wall of Flesh always spawns facing away from me and moving towards the closest border of the world (i.e. if I'm east of the spawn point, he will appear east of me, heading east). This makes for very quick, very messsy battles with him, which I inevitably lose.
I attempted to simply spawn him in the middle of the underworld and he simply did the same thing – he spawned to the side of me, moving away. Since I was behind him, he dragged me in front of him, which had the unfortunate effect of trapping me against an underworld skyscraper underneath my bridge, drowning in a pool of lava.

If you are on the left of the exact middle of the map, he will go the left toward you, and vise versa. Possibly try looking both ways when trying it.
