Hi all, I'm trying to find a way to update many blocks at once without lag. I read that setBlock() is very slow, and I found other methods, like getByCombinedId() or chunkCoordIntPairQueue, that should be more efficient. The problem is, I need to import net.minecraft.xxx.xxx and I get the error Cannot resolve symbol 'minecraft'. I'm using IntelliJ with the Minecraft Dev plugin. Any help would be greatly appreciated... Poplo.
