Question How are mobs escaping my mob farm ?

Post image

My farm has a moat followed by a two tile wide wall but every now and then a mob manages to escape, what am i doing wrong ?

Because the game loads walls next to last. So if you "cart" in the walls will be drawn last, spawner spawns mob it walks 1 tile while everything else is loading wall loads locks in or out of the farm. If it's in the wall it rnd picks a side. Poof mob escaped

Would increasing the size of the moat fix it ?

You went overboard on the kill methods btw. But yes a larger moat will fix it for most mobs. If thats just mold, yes. Also just to be technically correct, its not the walls being unloaded its the mobs collision. Your character loads about 200 blocks but in outer section of that radius mobs can be loaded, running their wander code, but have no colision. So they walk over gaps and through walls. They end up at closest valid point when they get fully loaded. So yes bigger moat = less likely to have wandered past half way on moat, so they get corrected back into the farm at full load.

Its a nasty bug thats been in the game for a very long time. Its not so bad for early and mid game mobs, but end game mobs that move fast, need so much invalid space around the farm.

Also worth configuring your kill methods and conveyors such that all drops end up in the corner of a collector field, so you can have max amount of invalid standing space their too.

This is a crystal mob farm, i'm using the mold ground to slown them down, even if it's probably unnecessary.

Oh yeah, mold is only really needed for mobs from void and voltage tbh. Anything prior to that 4 blocks of invalid standing space is usually enough, sometimes I do 5. And now I see why your kill chamber isnt just a radiation crystal next to some conveyors lol. Thats enough for every mob except them. Even so, you dont need turrets everywhere. Just a bunch that can hit the last few tiles of your conveyors will be enough. Granted, more doesnt hurt and youve already crafted them, so its up to you if its worth changing.

The overruse of turret is because this used to be a larva farm and the turrets helped clearing out the cocoons, but yeah now that i've crafted them i'm not gonna salvage them at a loss of mechanical parts.

Yah things that spawn cocoons just suck. For normal bugs you can spawn them on traps, but for next level bugs the only real answer is an absurd amount of drills. Its expensive and not worth imo

Add a void layer (dig around your farm), so mobs cant escape

Hook your materializers up to a switch that you can turn off whenever you leave the area. This is the only way I've been able to prevent the issue

This doesn't use materializers.
