Set Unit Xmod, Y Mod and Height data from unit ID
Jump to navigation
Jump to search
Parameters : r4 = Unit ID
r5 = previous routine stack pointer
Returns : r2 = 0x00 if unit misc data pointer is invalid (no data stored)
r2 = 0x01 if unit ID point to a valid Unit misc data pointer
Store data on previous stack pointer :
- 0x00 Unit X mod ((X coord.)*28 + 14)
- 0x02 Unit Height data
- 0x04 Unit Y mod ((Y coord.)*28 + 14)
