I am reading the docs, specifically GDScript basics and there is this section about coroutines I am struggling to understand:
If you're unsure whether a function may yield or not, or whether it may yield multiple times, you can yield to the completed signal conditionally:
I was having a tough time understanding the code so I ran it in godot to see what happened. Because of the pseduorandom nature I modified the code slightly (but I don't think it changes the example). Here is my code I used:
var result = rand_range(-1.0, 1.0)
if result < 0.0:
var result = generate()
if result is GDScriptFunctionState: # Still working.
result = yield(result, "completed")
Here's what I am struggling to understand:
It's my understanding that this code is supposed to always return a random number (above 0?). But sometimes I get a random number, sometimes I get a function state.
With this example, I'm not sure how yielding to the completed signal conditionally works.
This is particularly difficult, because I'm not even sure what this part of the documentation is trying to teach.
Sorry for the bad question, but thanks for reading and I hope you can help.
