Command Actions

Command Actions provides an interface to automatically run .mcfunction files at particular events. They are loaded from the filesystem on every event call, ensuring that they are as up to date as they can be.

How to run functions?

• Open / create the .minecraft/config/command-actions/functions folder
• Add function files or folders containing function files with the proper event names
• Functions are detected either without an extension or with the .mcfunction extension.
• All files in subdirectories are detected regardless of extension (or lack thereof)
• Subdirectories are recursed to find functions

Current capabilities

Some preprocessing occurs on the input. All preprocessing directives are preceded with a hash (#),
and any line preceded with a hash that is not a preprocessor is marked as a comment.

Preprocessing directives:

• if, elif, else, endif – check if a given macro evaluates to true or 1, if a number is nonzero, if an equation results in a nonzero answer, or if two values are equal or unequal
• define – define a replacement to be replaced later. Not recursive
• undef – remove the definition of an already defined macro. This also works for system-provided macros.

Current events

Built-in macros are listed, and all builtins (including those provided by other mods) are preceded with C_
