Clicking the Green Flag will run the simulation with the current weights. Open the Editor by clicking the 'Editor' button, or by pressing 'e' or '0'. Change the number of particle types, change the number of particles in the simulation, change particle weights and more in this (totally) state-of-the-art project! The particles do lots of stuff that I do not understand, but it's a feature not a bug
I saw some videos like this on YouTube and wanted to try making it in Scratch! I could probably make this a little faster if I used cloning instead of stamping (that's faster, isn't it?) but it's still fun to play around with. There was another version of this project when I was making it which had this really cool particle editor but I thought I'd go with a more simple editor instead for simplicity and hopefully performance. Changelog: Oct 2, 2022 Initial Release
