how do you add a game update to a function block?

You can’t do that in blocks. What are you trying to do?

Yea, you would need to switch to JS for that. If you want to stick with blocks, I would do something like this:  
 ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/2X/8/80123daa436e377b50cf9d9c83b315635e1421f9.png)  
And you probably want to use a `on game update every {number} ms` because the `on game update` runs _every frame_ so it will spawn quite a lot of projectiles.
