enter image description hereI made my mob farm at height 200 and the collection area is on 70

There is no mob spawning, so where should I be idling so I get highest mob spawning rates as possible? I attempted to idle at the collection area but no mobs spawned so I presume I need to be closer? What is the maximum distance from the mob spawner that it'll still work?

  • Generally a good place is above the spawner.

    And why do you have the collection are so low? 30 blocks is more than enough. 130 is overkill

  • I placed collection so low just beacuse I wanted it on the ground so I don't have to climb always so high. Jul 10, 2015 at 12:52

    I think 128 block distance is the absolute maximum range in which a mob can spawn! Jul 10, 2015 at 13:47

Your idle area is 130 blocks from the mob spawner, which is just over the 128 block radius from the player outside of which mobs will not spawn:

Mob spawning

You should move your idle area up to at least level 72 if you want to see any spawns at all, but I'd recommend having the idle area at y level 175 if you want to reduce the number of mobs despawning.
