I've been searching around for a tutorial on structure generation and can't seem to find anything. I can find people asking questions about it, but lacking all knowledge on the subject means I can't piece these together into something functional.

After googling around a bit, this seems to to be the go to way to check if a specific item has been picked up. @SubscribeEvent(priority=EventPriority.HIGHEST, receiveCanceled=true) public void onEvent(EntityItemPickupEvent event) { if (event.entity instanceof EntityPlayer) { System.out.println(entityItem); if (Item.getIdFromItem(event.item) == Item.getIdFromItem(MODITEM)) { } } } However, Item.getIdFromItem takes Item as an input, and event.item outputs ItemStack. Nothing in event.item.* outputs Item either. Have I just been finding outdated snippets of code, or am I doing something wrong? The only other way I can seem to find from poking around event.item.*, is to convert event.item.getEntityItem() to a string, and then remove the beginning and end of it so it's just the unlocalized name and comparing those, but that seems clunky.

Thank you for the assistance.

Is there anything other than changing the home variable I have to do to stop running 8? Do I have to change something in Eclipse?

Alright. I downloaded JDK 7 and installed it. Then I changed the JAVA_HOME variable to JDK 7, restarted, and made another environment from scratch. No apparent change.

I've tried setting up the environment from scratch multiple times, but this occurs. Even when the only package in src/main/java is the default example one. Nothing I've found has really been much help.
