Function Definitions

Function definitions are used to create new functions. They can be used inside of Directories, or in the root of the .mcb file.

function <name> [function-tag] {
    <...>
}

function-tag is optional and can be used to add the function to a tag. If no namespace is specified the local namespace is used.

Examples

Creating a Function

function hello {
    say Hello, world!
}

Adding a function to the minecraft:tick tag

function hello minecraft:tick {
    say I spam chat every tick!
}

Adding a function to the minecraft:load tag

function hello minecraft:load {
    say I'm polite, and only say hello once when the Data Pack loads!
}

Adding a function to a custom tag

function hello my_namespace:my_tag {
    say Hello!
}

If no namespace is specified the local namespace is used.

function hello my_tag {
    say Hello!
}
