Lesson 13: Preventing Health From Going Below Zero, missing health variable in text.
In "Lesson 13: Preventing Health From Going Below Zero", goals text dont give information for variable health. If defined in code by user, it gives errors. I suggest adding a text regarding "variable health" is predefined by you.
if you declare a variable inside a function, that variable only exists within the function. I believe for the purposes of this exercise, you should use the robot's health variable, as declaring a var inside the function would not modify the robot's actual health. @NathanLovato
Yes, that's correct.
I would say it's more of a general issue that would need to be handled throughout the app as this applies to many practices: ideally we'd expose member variables in all practices, and also protect against their deletion or shadowing with a clear feedback message to the user (like we do in our newer practice system GDPractice/in our Godot 4 curriculum).
There are a couple of holistic changes like these that the app could use, but it's a really substantial amount of work.
