Unfortunately this had to be done in the base class so that we can still maintain the walls in a global array.
The tradeoffs of better abstractions would be far too costly here than the added 16 bytes to the wall struct.
Mainly using int16_t for deliberately sized struct fields, auto for temporary saves of global data and making several local variables full int.
This changes nothing substantial.
