Player overlaps with building = 0 blue
Player not overlapping with building = 1 blue
Building hitbox overlaps with road = 0 red
Building hitbox not overlapping with road = 1 red
These blocks don’t seem to be working for some reason even though in previous versions they did?

Simplified model of how its supposed to work
If someone could help either explain the issue or even fix it that would be great but I’m doubtful anyone can understand my messy coding 😅

Sadly I don’t think I can continue working on the game because of this issue. A bigger issue is that makecode can’t really handle that many sprites so unless I figure out a different overlapping (with building) detector that doesn’t use sprites as hitboxes, the game will always have a fundamental limit on the number of buildings that can be placed down (about 15-20 before lag is very bad)

i made a isometric extension a while back the only thing is that it didn’t have movement BUT thanks to your game i figured out what the problem was and i fixed it

while making the movement’s i realized i made a mistake THE Y AND Z ARE SWITCHED, NOOOOOOOOOOOOOOOOOO. when i tried to switch them the tileMap was all wrong and i couldn’t fix it, so ya were stuck with switch y and z

How will you implement jumping and collision?
