Generate commands from a Kotlin native entry

A native entry can append commands during compilation. This ready() entry makes the generated datapack send a message.

src/main/kotlin/example/mni/Messages.kt:

package example.mni

import top.mcfpp.annotations.MNIFunction
import top.mcfpp.model.function.Function

object Messages {
    @JvmStatic
    @MNIFunction
    fun ready() {
        Function.addCommand("say MNI is ready")
    }
}

src/main/mcfpp/main.mcfpp:

func ready() = example.mni.Messages.ready

func main() {
    ready()
}

Build with mcfpp build, load the datapack, and call main. It executes say MNI is ready. Function.addCommand takes the command body without /; selectors and coordinates use the runtime execution context.

Kotlin if selects generated content using build-time data. MCFPP if controls which generated branch executes at runtime.

This page uses the native interface, which exposes compiler command objects. Structured macros use MacroContext and CodeScope to build expressions, loops, and context operations. See Kotlin macros, Minecraft operations, and the Command API.
