Mobs will despawn when they are out of a 128 block radius of the player. This means that for the spawner to be active if the player is anywhere within 128 blocks at the spawner’s level, it has to be at least 128 blocks above the ground.
What prevents mobs from spawning?
One of the most basic ways to prevent mob spawning is by placing torches. These will increase the light level around them, stopping hostiles from spawning. Other blocks such as glowstone or shroomlight emit higher light levels, but are harder to come by.
Is there a spawn trap up in the sky?
I’ve made a giant mob spawner/killer up in the sky (y=220-235) over an ocean. Light level 1 spawn floors, 540 block area, 3 high, periodic water flush that pushes mobs into a pit, where fall damage kills them. Problem is, mobs seems to rarely spawn inside, and endermen just vanish.
Why is my spawn trap not loading in Minecraft?
Mob traps built close to the sky limit have been known to end up not being completely loaded by the engine in some situations. The way to test for this is to open the F3 screen and look at the ‘lc’ value. This number is the highest Y-level that is currently loaded.
How often do mobs spawn in the Minecraft spawn trap?
If there is a cave system under your mob trap (underground) the mobs will rarly spawn in your trap. The water is on a timed piston circuit, probably about 30 seconds between flushes, which last about 10 seconds each. So, the whole trap floods every 30 seconds or so. (Does that affect spawning, or detection of spawnable areas?)
Why is my mob spawner not working in Minecraft?
If there are lots of caves nearby they are likely spawning in there first and not having enough ‘mobs’ left to spawn in your spawner. I suggest filling in nearby caves, and destroying any dungeons below you if you were unfortunate enough to get one there. – RhysW Jul 17 ’13 at 10:48 Perhaps add some light and then take screenshots?
