Godot Version
i am using godot 3.5
Question
for a hardware limitaion reasons i am using godot version 3.5;
in order to make souls-like prototype i am using (catprisbery) 3.5 template, i tried using his other template for version 4 as guide line (i like his methode because it reusable and expanble) to implemante new features but i stuck on (health_changed) signal .
the editor gives me an error that the signal isn’t declared in the scope yet it is in the top of script so it should be global to the script i wonder if it is the typing but it is right; plz help i cant figure this out.
thanks.
