Instructions and notes
Parameters : r5 = Tile elevation
r4 = previous routine stack pointer
- 0x00 = X mod (X coord * 28 + preset value)
- 0x02 = Elevation
- 0x04 = Y mod (Y coord * 28 + preset value)
Returns : r2 holding Height data as negative value depending of slope type
- (Height*12) if halves = 0 or unsupported slope type
- (Height*12) + (preset/28)*12*halves (depending of slope see notes)
- (Height*12) + (1- preset/28)*12*halves (depending of slope see notes)
NB : is preset is 14 , same result for all slope
