I am using KCauldron which is pretty much Spigot and Forge at the same time. Now I need to cancel and events to do with interacting with entities. Except for CustomNPCs, which is a problem since it is a Forge mob. I made my plugin broadcast the entity's class name. And if I right click a customnpcs entity it broadcasts org.bukkit.craftbukkit.v1_7_R4.CraftCreature But CraftCreature could be anything, too. Any ideas?
