Minecraft – Spawn Point in End Portal

Ensure "local server multiplayer" is enabled in options.

Ensure none of the devices is using a VPN.

Ensure ALL of the devices have the latest version of Minecraft PE. If that's not so, there's no way it's going to work.

To update an app on iOS:

1. Open App Store app from home screen.
2. Browse into updates tab.
3. Scroll down to find Minecraft PE.
4. Press the "UPDATE" button next to the game.
5. If needed insert Apple ID password.
6. Wait for update to finish.

Repeat this for all iPads.

Ensure all the iPads have A DIFFERENT MINECRAFT NAME!

You can change the name in Options menu, from "Steve" to something else.

If it still doesn't work, this might be a issue with Unique Device Identifier of Minecraft. Reset it by uninstalling and reinstalling Minecraft PE. This will unfortunately remove the worlds.

Assuming they work the same way on pocket as they do on PC:

A pair of Tripwire Hooks need to be used with String in your hand to set it up, then if someone walks over the string it'll produce redstone current. They can also be used to craft Trapped Chests if those are on Pocket yet, which produce redstone current when opened.

The Note Block can be customized to produce notes of different pitches and plays the note when the incoming current switches from off to on. To place the note block in creative mode, it's on the third tab (the one with the bookshelf), and it's the second item on the 4th row in (I have 18 items in a row). It looks like it's a box with a brown and black checkerboard on it.

Levers produce their own redstone current when on, and don't need an exterior power source.

An Activator Rail modifies the function of minecarts driven over it.
