I've recently had many of my users making cactus farms and such which can really cause lag from all the drops. The plugin NoLagg, however, has a solution to this problem. Everytime a drop goes near another, they are combined into a single drop, but when picked up, 2 drops are collected. I'm desperate for this feature, but unfortunately Nolagg being such a big plugin, really grinds my server to a halt. Basically, I need a plugin that does this as a single feature. I think I've made sense, please let me know if I haven't Thanks,
there is an exact plugin for this called something like Stackit? Stackker? just search on bukkitdev for "stack" you should find it. Il go dig it up for you if you can't see it.
I found a plugin that seems to do the trick now: http://dev.bukkit.org/server-mods/itemstacker/ Needs one or two extra features, but otherwise it works Thanks all!
