Way to go Jamie, that's great!
Regarding your question on how to trigger the stars in order, you could do something like this:
Star 1 (Normal / complete)
Star 2 (Normal / complete)
Star 3 (Normal / complete)
Newspaper (normal / drop correct)
Banana peel (normal / drop correct)
Cereal box (normal / drop correct)
Create number variable = Count, set at 0
Trigger 1:
Add 1 to Count when state of any (Newspaper, Banana peel, Cereal Box) is equal to Drop Correct
Trigger 2/3/4 etc:
Change state of Star 1 to complete when variable Count changes, on condition it is = 1
Change state of Star 2 to complete when variable Count changes, on condition it is = 2
Change state of Star 3 to complete when variable Count changes, on condition it is = 3
I’ve done a quick mock up you can download so you can see how it works:
https://drive.google.com/file/d/1Moobc9r94kfPdx1UrG9vhzNx6OQ64bK8/view?usp=sharing You’ll need to refine it a bit and consider what ifs. For example, what if the user drags an item onto the target, but then drags it off? (depending on what it is, I sometimes change drag objects to Disabled once dropped, so they can’t be dragged off)… and things like that, but you can build it and then get it tested to see what users are doing and how you can resolve any issues.
Hope this helps!
