About the project

My friend Nedraw is a datapack developer, and we're working together on modding and datapack development. To help him out, I made an api for him, so he can make datapacks easier and with better performance.

I decided to open-source and publish this so I can help other people out.

Here are the features this mod adds.

• /data math
  

This command allows you to do more complex and faster math operations.
Here are some examples on how to use the command:

/data math <operation> with <input_nbt> (Will just show the result in chat)
/data math <operation> storage <storage_identifier>
/data math <operation> storage <storage_identifier> <nbt_subpath>

• /data variable
  

This command allows you to set and get specific variables for an entity. Here are some examples on how to use the command:

/data variable <add|set|get> <variable> (Will just show the result in chat if get)
/data variable <add|set|get> <variable> to <storage_identifier>
/data variable <add|set|get> <variable> to <storage_identifier> <nbt_subpath>

• Ridable players
  

You can have entities mount and dismount onto players; the player being ridden cannot force the entity to dismount.

Example of using /data math (the NBT schema is the same for variable)

/data modify storage minecraft:test in set value [43,35] (Storage nbt: {in:[43,35]} )
/data math add storage minecraft:test (Storage nbt: {in:[43,35],out:[78.0d]})

Math operations

For all arithmetic operations, the input is an array of numbers of any size. If the size is more than 2, it will treat it as chaining the operations, for example, if it's an add operation with 4 inputs, it will sum it all up.

If you want to know what these operations are, just search for them.
