For those who don't know, Jen-Scripts is my library for procedural terrain generation in GameMaker. It is some truly ancient Cloaked Games code, first published in 2018. I started working on it around when I started The Last Librarian!

I'm writing this post to formally announce that I am working on the v3 update for Jen-Scripts. It's real this time I swear... This will bring Jen-Scripts up to a reasonable standard for modern GML. I am rewriting almost the entire library from scratch, including the documentation, and adding new powerful features. So far, I am 36% finished with the overhaul, though I feel that the hardest part has passed (getting started).

Here are a few of the things I'm working on with this rewrite:

• Support for latest GameMaker versions including both LTS and monthly.
• Full JSDOC/Feather and rewritten documentation w/ examples.
• Renamed and restructured functions for better consistency and readability.
• Optional array support for replace/new_value, to allow changes to multiple values in the same call.
• Optional setter parameter to override the test and set step of every compatible function.

As a concise example of both of the last two changes listed above, this allows something like:

jen_replace(terrain, [obj_dirt, obj_grass], obj_rock, jen_set_not);

In v3, this function will replace everything that is NOT dirt or grass with rock. In my testing so far--including use in my other projects--these features dramatically expand the flexibility of Jen-Scripts, making new things possible, and old things possible in fewer lines of code.

Needless to say, I am very excited to get this update finished for everyone else to use. But, it is taking a long time. This post today is my commitment to follow through with it, and I will try to post future updates as I make progress to keep folks in the loop.

P.S. The source code is on GitHub, the branch named 3.0.0 has my latest work if you want to see what I'm working on or try it out.
