(I'm used to coding with other languages but Java is kind of new for me) I'm trying to create a totem of undying-ish item that gets used upon death. Everything is working, except I can't remove the item using clearMatchingItems. On the docs (https://skmedix.github.io/ForgeJavaDocs/javadoc/forge/1.9.4-12.17.0.2051/net/minecraft/entity/player/InventoryPlayer.html#clearMatchingItems-net.minecraft.item.Item-int-int-net.minecraft.nbt.NBTTagCompound-) it says that the method needs an item, a metadata, and an int, but in my IDE (Eclipse) it says I need a predicate <itemstack> instead of an item (maybe the docs I'm looking at are outdated). My question is, how am I supposed to use predicate with Itemstack, and if I need a metadata how I would use it?

Metadata is old you are looking at outdated docs. A predicate is just an interface with one function you can use a lambda for it. The predicate is supposed to determine if the ItemStack passed as a parameter matches the item you want to remove.

Thanks, I went through it again and fixed it up. It's working fine now.
