To follow-up from what Mike said - thanks for bringing this up. In looking into it, this highlighted some work we can do on our end to make the documentation clearer and more functional, and we’ve got some plans to improve the Game Lab documentation to help address the confusion you noticed. Here’s what I can say for now:
For right now,
When you use these functions in your code, they will still turn up as green blocks as if Game Lab doesn’t recognize them. But, they will still work correctly when you run your project. I’d recommend making a new temporary project just to play around with these functions and use text mode, then switch back to this project once you’ve figured out how you want to use these blocks to solve your problem.
Longer term: we’re looking into updating Game Lab so our array blocks could work here too, but I don’t have an ETA. Since these blocks aren’t part of our Game Lab curriculum, they won’t be prioritized as high as other updates that more directly impact the curriculum.
