Bug Infinity 1.1.0 Auto-spawner wont spawn ghasts

[SuperDino]

I have a fully powered auto spawner with full mob essence with a 14x14 room that's 7 tall. And I've given it 25 minutes since full power, full work, and full mob essence was achieved and haven't spawned a single ghast.

The ghast is in a reusable safari net.
The floor is solid blocks (stone).
Other mobs (Imps, zombies) are both able to spawn using the same set up.
The chunk is a spawn chunk that was loaded the entire time.

Ghasts require a 5x5x5 area right? I'm so incredibly confused as to how this doesn't work and isnt an existing bug report, I assume Im making an error somewhere -- but from everything I read I'm not. It appears to just be broken.

After some more research I expanded the room to 16 x 16 and 9 tall. Still nothing. I am now sure it is not the size of the mob causing the issue.


Exact copy has been tried both enabled and disabled. Neither seem to work.

UPDATE:

This was a problem with incomplete information on the wiki. The auto spawner needs a non-solid block above and below it in order to spawn some mobs.

Anyways, this thread can be closed.

I had the same problem, a 3 tall enclosure always worked previously with MFR Auto-Spawner and Ghasts. But not in Infinity. Unfortunately I never re-built my enclosure to a bigger size to see if it worked so I can't confirm if a larger size solves it. What does "non-solid block above and below it" mean? Are you saying the spawner needs to be elevated up into the air? Instead of placing it flush into the floor, it needs to be elevated two blocks above the floor? Or just one block? Guess I'll have to experiment.

You should never put the Autospawner on the floor. Its spawning range is +-1 block in the Y-range for the feet of the mobs. As for Ghasts this is the "core" of the mob and they need a space big enough around them in order to spawn.

Instead you should have your autospawners hanging from the ceiling with at least 3 blocks space above the spawner(for ghasts make it 4) and a couple blocks space below(Conveyors take up the block they occupy, so if you use those to gather mobs then dont place those in the spawning range.

If you cut of the spawning range of the Autospawner you will cut down on the spawnrate. You will see the blue progress bar repeatedly fill up and return to zero quickly without spawning anything. This is because the blocks it intended to spawn something in are obstructed.

Thanks rhn. Yeah, I always embedded it in the floor because it looked a lot better (IMO) when you can hide all the ugly wiring/conduits. And I never used conveyor belts, I just placed 4 MFR Grinders around the perimeter of the enclosure which could cover the entire 9x9 enclosed spawn area. I guess I never worried about cutting down the spawn rates because I always end up with 100,000+ of every item that a mob can drop regardless of whether it is "100% efficient" or not. LOL The important part to me is always how "clean" the build looks - exposed conduits just isn't my idea of a "clean" build. (shrug)

But since the algorithm has changed and Ghasts no longer spawn like they did in 1.6.4, I guess I have to "go ugly" then. Gotta deal with it.

You can do it without it looking ugly:

Slab some Facades/covers/use EnderIO ME conduits/whatever on the ME cable and you are golden.

New post got a bit better look at the mechanics behind the scenes:

Yeah, I do realize that the "ugliness" in my worlds stems from me, not from the game... I'm just not a builder - don't have the patience or the desire to spend time experimenting with designs until they look good. Other people like yourself don't have any problem making these great-looking builds. I know you don't just snap your fingers and it magically appears, I know it takes a lot of hard work, trial and error and a good imagination. Ah well, I still have fun at the game tho, in my own way. Thanks for showing me but it never seems to help!

Ooh
I never encountered this problem since I would always have some kind of pipe beneath the spawner.

Just threw this together to better show the problem with not just the spawning area of the Auto-spawner, but also the size of the mobs:

The yellow and black blocks indicate boundary of blocks in which the feet/core of mobs can spawn (9x3x9).
An enderman for example is 3 blocks tall so if that is set to spawn on the top layer it will need 2 additional blocks of ceeling height in order to spawn. The Ghast needs 5x4x5 blocks of free space. So if you want to take advantage of all the auto-spawners spawn chances, you will need quite a large room as you can see(13x6x13 minimum!), yet the minimum size room for it is just two block narrower due to the Autospawner itself getting in the way.
