TJSON for GameMaker

Quick links: Blog post · Marketplace · Documentation

TJSON is an extension for GMS1 and GMS2 that offers an improved set of functions for dealing with JSON.

Advantages include:

• Automatic memory management - no need to explicitly free the produced structures (more on memory).
• Type information - easily tell apart data in loaded JSON (more on types)
• Convenience - if you load a JSON string that has a top-level array, you get an array. If the JSON string is just a numeric value, you get that. No odd maps with "default" values (more on decoding).
• JS boolean value support - GML uses 1 and 0 as true and false values, so it is impossible to distinguish JSON true/false values in resulting data or produce a true/false value in encoded string. TJSON fixes that (more on boolean values)

The extension is compatible with all modules. Native platforms make extensive use of buffers to maximize performance. JavaScript-based platforms make use of browser's/system's functionality.
