I am experiencing weird spawning behaviour on my private MC Vanilla Server 1.7.9. Basically we have had 3 different Projects where we encountered this behaviour now. We don't know how to fix it and we don't know why it happens. I hope some of you have an idea!
- We are currently building a huge and very efficient witch farm based on this video / tutorial:
For that witchfarm we basically followed the tutorial and built it step by step. This is how far we are at the moment: At that point we stopped to see if it works and witches do spawn. However we went about 30 blocks away and hopped into creative. After 10 min nothing happened - not a single witch spawned. 2 hours later I came back alone on the server and what happened? 6 Witches there instanstly! In both cases we have had about 80 Entities around - absolutely normal and witches should have been able to spawn regulary at both times.
After I saw that, I brought my friend back online and we looked into it again. It seems that witches don't respawn if 2 persons are on the server (even when they are in the same area!). The moment my friend went offline 4-6 witches spawned in about 5 sec. At that time we have ad about 90 Entities in the area.
The same happens with my big mobfarm. Basically its a HUGE spawnarea way up in the air at ~120. Its built quite good, all is dark and once I am up in the air, mobs can only spawn in that farm. Once two players are online no monsters spawn. Once a player leaves (sometimes) they start spawning and i get a massive amount of drops out of that mobfarm - about a chest full in 10 to 20min. However this only happens sometimes. Very often the farm doesn't work at all. The only time it works is when I'm completely alone on the server.
The third farm where this happens is a new gold farm I made way up in the Nether. I basically used the dark oak trick to brake though the bedrock and went up to Y 250. Around there i build some spawn-platforms to see if it works. I do get spawns, don't get me wrong, however the spawns cap at 8 Entities. After that nothing else happens. So i basically paused my gold farm project there.
So in general: We have a very weird spawn behaviour on our rented gameserver. It's vanilla, its SMP and 1.7.9.
What could cause those problems? Why don't our farms work? How can we fix that?
Thanks a lot for your help and ideas! We are playing on that server for more than a halve year now and have build tons of stuff. It would be a shame if those 3 huge farms wouldn't work 100% ...
