FAQ

How do you make a command block conditional?

Shift-click on the command block icon in the GUI.

What is the commandblockide.bin file in my game directory?

It's used to store the multi-line versions of commands, since Minecraft doesn't natively support them. If this file is deleted, all commands will be collapsed to their single-line versions.

Why can't other players see multi-line commands in multiplayer?

Multi-line commands are stored in the commandblockide.bin file on your computer, which is not synced to other players in multiplayer. If you need to work on commands collaboratively, you will have to stick to single-line commands for the time being.

Why has my multi-line command been collapsed to one line?

Either the single-line and multi-line versions of the command are out of sync or there is no multi-line version available. This can happen when logging in to Minecraft from a different computer or when another player edits the command.

Can you port this to Forge?

No.

Can you port this to *\*?

No.

Can you update this to *\*?

Maybe.
