I really love how chapter 1 checks what dialogue an npc/interactable object should have by CHECKING ITS ROOM AND THEN ITS POSITION and determining what npc it is based on that. It must be really convenient changing code just because you had to move an npc.

Interesting thing to point out is that chapter 1 code was written by toby fox himself while chapter 2 code onwards is written by separately hired coders team (main reason being toby's terminal wrist pains getting way worse, but this decision arguably benefitted the game like in every way possible)

Another very big benefit of the split chapter system - they can work on future chapters before previous ones are released, with a guarantee of automatically not leaking anything. e.g. I'd imagine having to have the whole ch5 platforming implememtation on a branch for the span of 2021...2025 would've been massive pain.<br><br>Honestly I feel like that approach just simply makes sense. They can add new things without worries, remove old special-cases or entire systems, refactor freely; in a merged codebase, previous chapters would effectively just be legacy code doing almost nothing except rotting away.

Omg this feels like such a coincidence, lately I'm trying to read through dt and ut code to make something in gml and having a video breakdown on some mechanics will help more fs. Thank you man!!

My theory on game change is that, since deltarune never released on Xbox, and possibly toby just doesn't want to, the gamemaker devs didn't need to also implement gamechange for xbox

<a href="https://www.youtube.com/watch?v=b4VLSBLglgc&t=40">0:40</a> THAT'S how they did it???<br><br>Dude the moment I saw that movement I was wondering how they programmed it... My guess was perhaps some keyframe system combined with some movement smoothing?<br>But no it's basically a spritesheet for positions<br>And also YOU GUYS COULDN'T EVEN MAKE IT AN ARRAY AND INDEX IT BASED ON TIME OR SOMETHING??
