AESTD is a utility datapack written by Aeldrion for Minecraft vanilla 1.14 that adds useful functions and tools to help making complex command systems easier. Its development started in July 2018.

AESTD function library
The AESTD function library is the biggest feature of AESTD. It is divided in seven folders:,  ,  ,  ,  ,   and. Every function contains a comment documentation stating in what snapshot or version the function was last tested.

It contains over sixty functions that can do, among other things, the following:
 * Biome/weather detection
 * Precise entity damaging
 * Player inventory manipulation
 * Generating random numbers
 * Getting the name or head of a player

Useful tags
AESTD also features several item, block and entity tags.

TPS calculator
The TPS calculator is a tool of the  namespace. It evaluates the ticks per second on a ten second period. To use the TPS calculator, use the command.

It uses the shrinking of the world border to compare ticks and actual time. When a TPS test has started, it must end before another TPS test starts.

Save chunk
The save chunk (positioned at x=1519204, z=0) is a chunk that AESTD uses to save data used by other functions. When AESTD is loaded for the first time in a new world, it will ask players to run a /forceload command to mark that chunk for force loading. Its loading is essential for many functions to work.

Setting up the save chunk
When you first load AESTD in your world, a message should appear in the chat, saying "WARNING - AESTD is not fully loaded. This may cause datapacks to malfunction." with a link suggesting a  command. Click it, and AESTD should load.
 * If you are not an administrator of the server: contact an administrator and ask them to run the following command:
 * If you are in singleplayer with cheats disabled: pause the game, click Open to LAN, set Allow Cheats to ON and click Start LAN world. You should now be able to run the command by clicking the link.

Merging your datapack with AESTD
If you want to share your datapack but don't want to tell people to download two datapacks, you can merge your datapack with AESTD by going through the following steps:


 * 1) Copy namespaces to your datapack. Open the AESTD datapack. Copy the ,   and   namespaces and move them to your datapack's   folder.
 * 2) Move loot tables to your datapack. Open the AESTD datapack. Go in   and copy loot tables to your datapack, under the   namespace. If your datapack modifies the player loot table or the orange shulker box loot table, make sure players still drop their heads when killed with   tag and that orange shulker boxes still drop only their contents when broken with a tool with the   NBT data.
 * 3) Merge  . Open your datapack. Go in   and add the following function:  . If there is no such file or directory, create it and copy from.
 * 4) Merge  . Open your datapack. Go in   and add the following functions: ,   and  . If there is no such file or directory, create it and copy from.
