The setter function isn't defined

Question

I cant understand, why it is? how can I fix this issue. please help me. Thanks!

Answer 1

You wrote

var score = 0 setget set_score

That means that you want the setter function to be called "set_score". You have no function defined with that name. You do have

func set_get(new_score):

But I think that's not what you meant to name that function.
