I have a small vanilla server with a run.bat that runs it with 1024m. I only play it with one other person, and it constantly crashes when traveling over the overworld generating new terrain. I have 8gb in my system - more than enough - but am only using the 1gb. I've read that it might be a malware or firewall issue, but I don't know if that's true and no idea what to do about it. Getting really frustrating. Here is a crash log.

Hope nobody is bothered by my trying to answer this, but here I go. If I understand the program properly, you will have needed to generate a chunk that contains a village or an ocean monument. If you have, then you can go to the "region" file and search the name "id" and the value "Villager" ( for a village) or the value "Guardian" (for an ocean monument), as those are the only places either of those spawn. If you find one, the x, y, and z coordinates are within the ocean monument or village you are looking for. I'll make and put up a video of this tomorrow.

EDIT: It's up, tutorial at hope it helps:D

Hm... Because I've looked at coords for villages, and there weren't villages there. However, the desert temples were present at their coords. Thanks for taking the time to explain it to me.

Hey, I have a custom world that makes biomes small as hell. Unfortunately, now, I can't find villages or ocean monuments. Now, I've never really used NBT, so I may be asking a stupid question, but does nbt store data for ocean monuments? I can't find it in the data folder, though I can see strongholds and fortresses. Hopefully you can help me out.

I'm talking about survival, not creative.

Bump. Anyone know of a mod, or know how to do something like this?

Peaceful mode erases hostile mobs, but that also means we lose access to easy ways of acquiring gunpowder, flesh, bones, etc. It's also fun creating large farms for hostile mobs. And lastly, who doesn't want the ability to casually hang with those hostile mobs and chit chat without trying to kill each other?

I think it would be cool if peaceful mode kept hostile mobs, but pacified them. Perhaps they would only attack if provoked, although it might be best to just make them passive like cows, pigs, sheeps, etc.

I couldn't find a mod that did this after doing a search, and I don't know code at all. Any takers, or mods that already do this?

The design collects skeletons. A weighted pressure plate starts the system when enough have accumulated. First, a piston closes them off from new skeletons. Then it lavas them to low health. The piston in front of them retracts so they can continue, and another pushes them forward. Then it starts over.

It's a little overkill for a dinky spawner trap, but it was meant as a challenge for myself, and also because I like automation, especially with softening mobs, which is not something usually approached since most spawner designs are already fairly productive.

Bump. Even a "This is dumb" is feedback. I found an automatic mob softener using Etho's timer, but that isn't perfect. If anyone could help improve my design, it would be appreciated.

Hey, all. I had the idea of making a spawner trap with an automatic mob softener, but I'm wondering if I can make it any more compact or neat than it is. I'm not very experienced with redstone, but I understand it for the most part. Can anyone help me make this any better? I have a download link, and some pictures if any one is feeling paranoid about the file.

This is kind of a weird request, but I was wondering if anyone knew how to stop chunks from loading. The reason is simply that I want a visual cue that I need not cave any further / light anything up. When I am lighting up caves and chunks are not loading, then when I come to the edge of the loaded chunks, I can turn around.

Or if anyone has any other suggestions, I'd like to hear them. I'm interested in ideas on how to detect that I've caved enough, other than simply checking the coordinates over and over again.

Thanks!

Bump. I think the last time I'll bump. If anyone has any ideas, let me know.

Thanks for taking the time to stop by. Any idea on improving the coal distribution?

Bump. Any help?

That's a video I posted of my mining processor. I was hoping I could get some help with improving it. Making it simpler, more compact, more efficient. You know.

Thanks in advance for any help!

Hey, Skidoodle, I've been using the map a lot for my latest world, and I've hunted down several villages using it, and unfortunately, every place I looked for the village, there was no village. The seed I'm using is "5137889379657791015". I checked for villages to the east of the spawn. I can confirm the temples are correct.

Also, I was hoping you could implement a refresh button for the player, so the position would update if the player moved. As it is now, you have to switch to a new map and switch back (unless I am unaware of a faster method).
