A GameMaker 2.3 extension that allows for runtime asset inspection, intended to fill in the gaps for asset-related functions that might be missing.
This extension is still heavily in development and is subject to changes and additions.
Additionally, due to the nature of this extension; runtime updates can break chunk parsing. At the current time of development, this extension targets runtimes 23.1.1.160 through 23.1.1.166

Parsers

meta's modular nature allows for you to easily create your own chunk parsers to handle any missing asset types. For reference, you can refer to the ChunkHandler class of my other project "Luna" to find the structure of some chunks. To create your own parser, follow the below steps:

1. Add the 4-character chunk name into the global.__metaHandlers__.Order array
   (NOTE: Be sure to keep in mind the order of chunk parsing, you usually don't want to parse any chunks before the STRG chunk is parsed)
2. Create a static method for the global.__metaHandlers__ class that parses the binary chunk
3. Add any functions to retireve different information for the new chunk
