The code Vemerion gave you is not complete. You now got the position of the spawnpoint, but you've never moved the player.

That's what I think.

use .Post, which is called after all buttons are cleared.

Use post otherwise the button you added will get removed afterwards.

PlayerInteractEvent.RightClickItem event

Minecraft.getInstance().displayGuiScreen()

Use RegisterCommandsEvent.

What is getActive()? And the casting and null checking is pointless and won’t work.

Update: It is still not working after I disabled nearly all features in the mod, but we got more testing results coming out: If A create the world and open to lan: B can't connect. If B creates the world and opens to lan: A can connect. If A host the local server: B can't connect If B host the local server: A can connect, but B cannot. It is really confusing because it sounds like a hardware problem but it happens on some other players as well, the client log always shows: [Netty Client IO #0/DEBUG] [ne.mi.fm.ne.FMLHandshakeHandler/FMLHANDSHAKE]: Registry load complete, continuing handshake.

Also I'm certain it is not the mod config's problem because the problem persists even if it is disabled.

player.getRidingEntity() or player.isPassenger() which isPassenger checks if the player has an riding entity

As diesieben said, use LivingUpdateEvent, check if the entity provided is wearing your armour (PlayerInventory.getStackInSlot()) with the enchantment, apply the potion effect.

What did you do and why do you think it is not working? Also you might find SkullTileEntity helpful since it stores player's data in it as well.

It uses RegisterCommandsEvent now.

createTileEntity.....

Override addInformation, you can check how SwordItem adds extra info.

double x = event.getPlayer().getPosX(); double y = event.getPlayer().getPosX <--------??? (); double z = event.getPlayer().getPosX <--------??? ();

maybe is because its container is bowl? if (stack_container == Items.BOWL) { ReturnUseAction = UseAction.DRINK;}

What are you trying to do?

The event provides an entity, and you can't store data like that.

So are your items food?...

That's not how events work, there's introduction of setting events in the link.

LivingHurtEvent and check if the damage source is lightning, cancel the event.

Check keyPressed in CreativeScreen

check RenderTypeLookup.java
