RestartRedstone Datapack

A minecraft datapack that lets you place "dormant" redstone blocks that get activated once for a few ticks on command.

Anyone can place those blocks, but only OPs can trigger them.

Minecraft 1.20 and above

To use this datapack, head over to Releases, find the one appropriate for your game version (or alternatively click on the green "Code" button in the top right and choose "Download Zip" for the latest code updates) and unzip the zip file into your worlds datapacks folder.

The folder structure should then look like thism where XXX is either the release you downloaded (e.g. 1.2) or main:

datapacks
└ RestartRedstone-XXX
  ├ data
  ├ pack.mcmeta
  └ etc.

How to use

Create

1. Stand on the block you want to turn into a dormant redstone block.
2. run /trigger restart_redstone in chat. The block below you will be turned into a dormant redstone block.

The dormant redstone block cannot be broken, moved or destroyed by explosions.

Remove

1. Stand on the dormant block you want to remove.
2. Run /trigger restart_redstone in chat. The block below you will be removed.

Trigger the redstone

To "wake up" all loaded dormant redstone blocks, run /function restart_redstone:run.
This will activate every loaded dormant redstone block, one by one, for 1 second with 1 second break between them.

⚠ After the system has been triggered, it can't be triggered again until the server was restarted or the /reload command was used.

On Hermitcraft this system is supposed to do some resets before a server shutdown, so this command is scheduled to run a few minutes before the server shutdown command is scheduled.

Settings

Starting in version 1.4 (for MC 1.21.4 and above) you can adjust this setting.

The setting is stored in the restart_restone.settings scoreboard objective and can only be changed by an OP of lvl 2 or above through a scoreboard command.

/scoreboard players set <settingName> restart_restone.settings <value>

whitelist

Default: 0 Enables/disables whitelist checking for the replaced blocks. Adjust the block tags to adjust the whitelist/blacklist (see below).

Value	Meaning	Description
0	No whitelist	There are no checks for which blocks can be replaced.
1	Whitelist	Only specific blocks can be replaced. (Default: only redstone block, see below how to modify)
2	Blacklist	Only specific blocks cannot be replaced. (Default: Some reasonable blocks like barriers, bedrock and thelike. See below how to modify)

Modification

Various things about this datapack can be modified fairly easily if you know where to look.

Change timing

To change the timing of the redstone blocks, check the functions run and run_one in line 7 and line 5 respectively. Change the delay of the schedule command to your liking. The delay in run defines when the next block is scheduled and the delay in run_one defines how long it stays on.

⚠ Be aware that the delay in run_one needs to be less than the delay in run, as the system isn't made to support overlapping triggers!

Change Whitelist / Blacklist

If you're using the whitelist/blacklist setting, you might want to adjust the selected list to your liking. The list is a block tag, located at data/restart_redstone/tags/block/whitelist.json (and .../blacklist.json respectively), or #restart_redstone:whitelist and #restart_redstone:blacklist in-game respectively.

To adjust the files, see here how tag files work and change the files/tags accordingly. You can either adjust the files of this pack directly (easier if you extracted the zip) or add another datapack (make sure it's loaded after this one) that replaces the relevant files.

Change appearance

By default the dormant redstone block looks like a normal redstone block. However, it uses a redstone block with a CustomModelData NBT tag of 1, so through a resource pack you can turn that into anything you want. Alternatively you can go into the setup function and modify the summon command to display a different block / item through the item_display entity.

1.21.4 and above

Due to changes in custom model data, it now uses the custom_model_data component not with a float of 1, but with a string value of "restart". So if you're changing the block through a resource pack, you'll need to update it to reflect this change.

Debug Outputs

The datapack outputs some debug messages for players that have the admin tag.

Allow for multiple runs without server restart

While it was not intended to be a global redstoneclock-like mechanism, it can well be used as one. To re-enable the trigger even without a server reload (or the potentially laggy /reload command), use this command:

scoreboard players set #hasRun restart_redstone 0
