I am creating a simple text-based adventure as a challenge and a class project, I will be really forcing my way through without looking up game design and such so I am sorry if this has a simple answer
I am unsure of how I can make "precise" boundaries for the character example image

currently, I have a small ImageView that moves a set amount(41) with keyframes, I would check if that move would make it past a set boundary, but that was to make sure it doesn't walk off the map. I am unsure now that I have tried to include walls and different-sized rooms and walls.
if it's too complicated or not possible I can make each room its own "map" but I was trying to save space and wanted the challenge but I can't think of a reliable way to check if they would walk into a wall. so I appreciate any suggestions, or even just a "go with plan b" thank you
