how do you get [gray blocks?](https://forum.makecode.com/t/gray-blocks-and-null/151) I don’t know how but it seems like a bunch of other people have done it! and whenever i have something that _cant_ be converted to blocks it just says i have to either discard or stay in javascript!
can you help me?

so that’s how you put a “on game update” block inside a “on start” or a function!

They are Javascript Blocks. They are blocks that were “created” that depends on the written code you have gotten
