Notes
Test Attacker ID < 0x15 - if not exit with r2 = -0x01
Test Attacker ID <> 0x00ff - if not exit with r2 = -0x01
Test Target ID < 0x15 Only if Ability is target specific (Attacker 0x178 = 0x06) - if not exit with r2 = -0x01
Test Action Menu < 0x10 - if not exit with r2 = 0x02
Jump to specific section depending of action menu, and set r17 and r16 (ability ID)
- Default and Monster : r17 = 0x01 (go to targeting routine) and set hit counter (nb of tile hitted)
- Item/Weapon Inventory/Attack/Jump/Charge : r17 = 0x02 (forces targeted panel to be the only tile hitted)
- Arithmeticks : uses a specific routine to set hit counter - r17 = 0x00 (hit coutner preserved)
- Elements : Change ability ID to match attacker's Tile ID, r17 = 0x01 (go to targeting routine)
- Katana : change Ability ID based on used item, r17 = 0x01 (go to targeting routine)
- branch to end with r2 = -0x01 if item is not a katana
- Defend/Change Equipment/Unknown1/Blank / Invalid Action menu (by branch) : jump to end with r2 = 0x02
- unknown 2 : branch to end with r2 = -0x01
If r17 = 0x01
- if Ability ID >= potion : branch to end with r2 = -0x01
- get in Targeting_routine - Set various AoE type and count hitted tiles
If r17 = 0x02
- get in Disable_Green_Panel_on_all_but_Target's_Tile and only keeps targeted tile (hit count = 1)
