View source for AI Target Unit for Direct vs Arc Attack (0019cd9c)

 '''BATTLE.BIN''' :  - AI_Target_Unit_for_Direct_vs_Arc_Attack_(0019cd9c)
 Ability simulation from a given position : handle Targeting and outcome. Test all targetable tiles, compare priority score, keep the best in AI 0x34 Table
 ------------------------------------------------------------------------------------------
 Parameter : Nothing
 Return : r2 = 0x00 Default result / No tiles to Target ( [[Set_Target_Tiles]] ) / AI 0x19bc = 0x00 (after checking priority)
          r2 = -0x01 if [[VSync_call]] returns r2 > 0x1b8
          r2 = -0x01 if [[Check_Set_Highest_Unit_Priority_(0019d308)]] returns r2 -0x01
