Jeg ønsker enkelt, hvis en node returnerer ‘ingenting’ så skal jeg få FALSE
Hvis den returnerer et resultat, så ønsker jeg TRUE
JEg får forsåvidt til TRUE funksjonen, men ikke FALSE dersom ‘null’ melding
Dersom node returnerer denne:
Ønsker jeg: bool = False
Dersom node returnerer denne:
Ønsker jeg bool = true
