How to use
- Download the archive
No need to unpack: the game reads the datapack directly from the zip.
- Place in the world folder
On the server - world/datapacks, in single player - saves/<world>/datapacks.
- Reboot
By command /reload or restart. The timer and login check will start on their own.
- Check
/datapack list will show whether it is enabled, and /function my_pack:load - whether the function will execute without errors.
What you need to know
- A timer is a schedule, not a tick counter. Function timer at the end puts itself in the queue again, and starts it the first time load. After /reload, the second circle will not appear: schedule by default replaces the previous one.
- There is no “player logged in” event in the game. The first entry is caught by the mark my_pack_joined, which the newcomer does not yet have, and the repeater - according to the count leave_game: It grows when the player exits. The check occurs every tick and costs almost nothing.
- Each tick is 20 times per second. It’s better not to use heavy commands (fill, search for all entities) like this: for “every second” a timer of 1 second is enough.
- No slash and no plugin commands. In the "/" function file at the beginning of the line is an error, and the game will not download the entire function. Plaguin commands in the datapack function are not performed at all.
- Folders - function and tags/function. From 1.21, the game reads only them, in the plural, silently; to 1.21, exactly the opposite. Therefore, the version is chosen: folders and a format declaration in the archive, under it.
Frequently asked questions
How can I make the command run every N seconds?
The function of the date pack, which at the end puts itself in line with the command scedele function...Ns, and first starts the tag load. Without plagins and command blocks, both on the server and in a single game.
How to execute a command when a player logs into Minecraft?
There's no vanilla entry event: in the teak, they look for players without a mark (first entrance) and with a growing number of leave_game (returned after exit), they call it a function and put a mark on them. The generator collects it himself.
Why doesn't the datapack function work?
Most often in the row is a cross line, the folder is called functions instead of function or as a plagin command. Check / datapack list and /function my_pack:load – the game will show error.
