It's been 2-3 years since the annoucement of "Undertale Battle Engine: Semi-Definitive Edition" (now renamed to Undertale Battle Engine: Turbo Mode). Here's a quick rundown on what has happened: - The engine unfortunately had to be built from the grounds up twice. The original engine, as far as it went, ended up being such a mess that I couldn't keep track with, so I decided to remake it using my own code, only to fumble halfway through from very poor optimization for Scratch. This time, I decided to make it fully Turbowarp-exclusive. And thanks to that change, I was able to properly utilize Turbowarp to its best. Not only are the limitations gone, but it also offers many more extensions (aka developers' best coding friends) that greatly sped up the progress. So far, the progress has gone pretty smooth. Also, it uses my own HP and box engine now (exception is the text engine from @PainInCode) instead of others' so editing has become so much easier as a process. - This new engine can now handle multiple enemies (more than 6 unlike what the screenshot says) and provide good and easy camera controls. Along with it is an interactive act system that can modify enemies' stats and broadcast certain events. - That's sadly all to it for now, right now only the ACT aspect for the engine is complete, others are still in experimental phase. More features are coming, however, so stay patient (or understandably not) for a few more updates. P.S: Yes, the full release of this engine will obviously not be on Scratch. It'll be absolutely broken if that's the case. And no, "Turbo Mode" is just a name, it won't be required to run in the actual Turbo Mode. If enough people are interested for an early peek at the progress, I'll consider linking to the file soon enough.
