So my old parser was really inefficient (https://scratch.mit.edu/projects/1305373437 for the link) So instead of using that, I completely redesigned it from the ground up! Plus I added sprite support, so now it looks exactly like how it would in Scratch (current example project: https://scratch.mit.edu/projects/817687184 ) If you didn’t know, this is a series of attempts to literally run an sb3 file inside of a project. If you wanna see more, there’s a studio right here: https://scratch.mit.edu/studios/51777366 This crazy idea might genuinely work?
