BATTLE.BIN :  - AI_Post_Action_Movement_Decision_Routine_(0019693c)
This routine will try to find a Panel matching distance and Priority score conditions, If this tile is found the routine update coordinates at 8019f3c4 + 0xcc4 (with an offset based on 0xe2d value)
------------------------------------------------------------------------------------------
Parameter : r4 = Maximum desired distance value
Parameter : r5 = 0x00 Priority prevails / 0x01 Distance Prevails

Return : r2 = 0x00 if no tiles found
         r2 = 0x01 if Tile found (Coordinates saved at AI 0xcc4 + word offset based on 0xe2d)

Notes (By Dokurider) :

Because this routine doesn't exclude ALL equal result cases, it ends up frequently saving the Last Panel Processed as the final result. This is different from how the other movement routines work and ends up causing some discrepancies and contributes to the AI's erratic movement.

+Notes (By Dokurider) :
   Because this routine doesn't exclude ALL equal result cases, it ends up frequently saving the Last Panel Processed as the final result. This is different from how the other movement routines work and ends up causing some discrepancies and contributes to the AI's erratic movement.
