Making an Code Block that attaches parts

So i’m making this project where you can design your own Marvel charecter. I was planning to make you able to play with it, but I realised that you aren’t able to. Theres already variables for it to know what part to attach, it’s just the Code Block that attaches them. It would become so useful for everyone not just this project! So please consider making one.


how do you even make something?

There is an Attach CoBlock. It looks like this:

Have you tried using this block?
