Minecraft stacked spawners

Do stacked spawners work? Do they spawn correctly and efficiently? I'm working on a farm, and I would like to know if it would work fine, because I'm running out of room to place spawners and I want to know if I can stack them.

Please only answer me if you actually know the answer. I need to know asap :p

Edit: On a server I watch, thecampingrusher He has stacked spawners. Iron Golem stacked spawners, and it works efficiently for him. Could this be with the settings of the server, if so, I need a Co-Owner/Owner to confirm if it is efficient, sorry if it sounds confusing xD


Here is an example of a stacked spawner:

 

I see no reason why they wouldn't work if they're stacked.

And I'm pretty sure the 'help' section is only for server-related things, so maybe that's why a staff moved it. That's my best guess :]

 

Oh okay xD A couple of my friends were saying they wouldn't work and I was like 'Why??' :P

 

]

It was moved because it wasn't relevant to the network

 

that's what I said.

 

Was just adding on the proof as you said

So I just wanted to show confirmation, and proof to support it.

 

I personally believe that stacked spawners do not work as efficiently as the are separated.

 

I believe so as well, but I don't have any proof to support it.
I also looked on the web on it as well but couldn't find anything more.
Hopefully you will have more luck.

I agree its confusing.
I don't think there are any server settings or plugins that effect or take into consideration whether the spawners are stacked or not intentionally, the plugins/settings only tend to change the spawn rates.
Also as for them being stacked or not, I now have no clue.

 

What spawners do is they check the area in which they can spawn mobs for the mob type they are spawning, and if there are too many of that mob within spawning range, the spawner will cease spawning in more mobs, as a check against the client/server being overloaded by hundreds of mobs.

However, if the mobs spawned by the spawner are moved out of range of the spawner's mob-checking zone, they no longer count towards the mob cap for the spawner. This allows mob spawners to spawn mobs until the overall server mob cap is reached, at which point no new mobs will spawn from any event across that dimension.

Multiple spawners placed near each other, such as when you stack them, share very similar ranges for checking mobs. They will also reach that mob limit much quicker, so you MUST move the mobs spawned in away from the spawners quicker than the spawner can create new ones to replace them.

Therefore, as long as the mobs spawned by the spawner are quickly moved out of the spawning zone, they should work as efficiently as if they were separated*


*When a spawner attempts to spawn a mob, it picks a number between 2 - 4, and will choose that many spots within its range to attempt spawning the actual mob. The area it can spawn mobs in includes spawning a mob directly on top of itself, which would not work if other spawners are placed there. So, once in awhile, you MAY get 1 less mob per spawn-attempt. This different, however is hardly noticable and is not worth the hassle of separating the spawners, in my opinion.

 

@ItsHarry
he's got a pig spawner
@ItsJerry

 

Thats just a visual glitch, I just placed it. Its a Spider Spawner.

Thanks so much! :D

 

Yeah.

 

I don't, like I said its a visual glitch. After placing it for 3 seconds a pig spawner will appear for 3 seconds.

 

Yeah.

 

I beleive they do work well.
