Hello! 😀

Anyone know an extension or a way to store functions inside an array? This means that I can use a “call” block and a “list get value at” block together to call a function at a given index?

returnng a value makes the function able to be used as this V

@anon30657772 there’s no built in way to do this, but you could create an extension to make this work.

typings might be weird though… but if the function doesn’t need to have parameters or return values then I could make an extension for it real quick

can you share an example function?

Yes but that would store the return value of the function, not the function itself!

For the purpose of my game, the functions have different number and types of arguments 🥲

I appreciate the offer! I’ll work on it myself though since it seems to be a good excuse to make an extension and learn typescript 😜
