Always. Post. Your. Code.

Yes.

It's an issue with the /dank/null mod. Report it to the author if you're using the latest version.

You can use == to check Block instances, as they are singletons: world.getBlockState(pos).getBlock() == Blocks.BED. This works for all IForgeRegistrys (look at the ForgeRegistries class).

Resources must be all lowercase.

EntityPlayer#inventory is an instance of InventoryPlayer, which implements IInventory. Whenever something isn't working, you need to post code. We can't help you if we can't see what you changed.

Don't cast the player to IInventory, use its inventory (EntityPlayer#inventory) instead.

That's up to you.

The Axis would be axis the bullet goes when first fired. The shulker uses the side it's attached to.

There are new methods in ItemPickupEvent, called ItemPickupEvent#getStack and ItemPickupEvent#getOriginalEntity. ItemPickupEvent#getOriginalEntity will return the same thing as ItemPickupEvent#pickedUp and ItemPickupEvent#getStack returns the stack which was picked up.

I'm using Forge 1.12.2-14.23.1.2555 and ItemPickupEvent#pickedUp is not deprecated. Which Forge version are you using?

Don't implement ICapabilityProvider in your Item class. You need to override Item#initCapabilities to return an instance of an ICapabilityProvider.

This doesn't have anything to do with Microsoft. People need to stop blaming Microsoft for the things that happened after they bought Mojang. We know, we don't like it either. But you'll have to get used to that.

That's the answer I give you in your other thread, which you didn't respond to. Don't make multiple threads for the same problem. Also, don't PM me. I won't help you there.

The disable button doesn't for most mods. You should create multiple profiles for different sets of mods, and switch between them when you want to play something different. That's bullshit.

Post the FML log (logs/fml-client-latest.log in your game directory). Also, stop using 1.8.9. It's really old.

Second line of the log: You need to run Forge 14.23.0.2500 or higher for JEI to run.

As said before, post the FML log (logs/fml-client-latest.log in your game directory).

What you described is from modders perspective, not the user perspective. Let's say you make an Item which attacks all mobs around you. The only thing a user sees is that all mobs around him/her are attacked. Describe from a user's perspective what should happen. This way we can help you with the implementation details.
