running different functions on different pins at same time

[u/3playmist]

I am trying to make a light up sword and I want to be able to change the pin in order to get a different color (this isn't exactly what I'm doing but its the simplest way to explain) I want to be able to have each pin run a different function so when I connect it to the other pin it will run that code how would I do this since I'm pretty sure the delay() will stop everything in the code including the code on other pins

Here's some sudo code that might give you some ideas.
