Generating simple procedural dungeon

I have a few questions. I made it all the way through but when I hit play the actor doesn’t do anything. I think I’m getting confused between what is in a function script and what goes in the construction script. Perhaps some screenshots of the whole construction script could help clarify? Thank you for your time.

EDIT: Did a bit of debugging and digging around and it seems my main arrays Room Sizes and Room Positions aren’t collecting any info?
