Quick Introduction
Commander is an extension of the vanilla data pack system.
It adds a new event system:
{
"event": "commander:after_killed_by_other",
"commands": [
]
}
Flexible JSON commands:
{
"type": "commander:commands",
"selector": "commander:random_player",
"commands": [
"/cmd:explode ~ ~1 ~ 2"
]
}
New / commands:
cmd:arithmetica:/cmd:arithmetica "round(346.45, 1)"cmd:explode:/cmd:explode ~ ~ ~ 4
Support for advanced expressions with data access:
minecraft:this_entity.isInWaterOrRain
/say ${{ origin.x }}
There are no client-side features available, everything is done on the server.
Commander is still in beta, so things can change, develop, break.
