BATTLE.BIN : Movement Routine
Called while spreading Move AoE. Each time it's called (always 4 times ?) it checks a different elevation and path
(Path on Tile or Path above unit). If Tile is a Valid and efficient destination it is flagged to become a future origin
-------------------------------------------------------------------------------------------------------------------------
Parameters : r4 - Some Counter : Determines destination's elevation and tested Path
r5 - Preset value : used as a movement malus
Returns : r2 - 0x00 if Valid Path (Possible and best) (only returned value checked ?) Destination Tile is flagged to be a future Origin
- 0x01 Destination flags 0x20 and 0x08 are OFF (Above unit path)
- 0x02 Destination flags 0x10 is OFF (Tile path)
- 0x03 Tile is too steep : flag 0x04 ON and Higher destination (Tile path)
- 0x04 Destination ceiling is too low (< than exit + size)
- 0x05 Origin Ceiling is too low (< Entry)
- 0x06 Destination ceiling is too low (< then Entry + Size)
- 0x08 PV <> 0x00 and Destination is higher
- 0x09 Acting Unit cannot Jump the vertical drop
- 0x0b Movement cost is too high (Unit Path)
- 0x0c This Path is a detour (Unit Path)
- 0x0d This Path is less convenient (Higher Vertical drop) (Unit Path)
- 0x0e Movement cost is too high (Tile Path)
- 0x0f This Path is a detour (Tile Path)
- 0x10 This Path is less convenient (Higher Vertical drop) (Tile Path)
- 0x11 Destination flags 0x20 (Unit Path - Exit without Updating moves)
