My teacher is having us use Alice 3 for learning about Java and it is a block code system like TheGamer101 posted.
Sparker22’s looks super cool compared to Alice 3, which is laggy and has so much copying of blocks (and you can’t add whole numbers and decimals).
I would imagine someone could make it a very complex plugin and have it load/save as lua scripts though, or even another program compared to adding it directly to Roblox.
