0017b874 - 0017bc74 Notes Parameters : r4 = Pointer to Attacker 0x16e to 0x181 data Returns : r2 = number of Tiles with "green panel" flag r2 = -0x01 (invalid coordinates, unselectable tile) This routine will set the "green panel" flag (Tile byte 0x05 - flag 0x80) on tile targeted by ability It will use the Targetable panel grid ( 0x80192dd8 ), using AoE (byte 0x00) and Targeted flag (byte 0x01) See notes ------------------------------------------------------------------------------------------------------ 0017b874: 27bdffb8 addiu r29,r29,-0x0048 0017b878: 27a50010 addiu r5,r29,0x0010

Notes
Tile will refer at 0x8018f8cc data (size per tile = 0x08)
Panel will refer at 0x80192dd8 data (size per panel = 0x05)
1st part : set targeted tile X, Y and elevation
- if ability stops at obstacle : Force the weapon ranged flag ON
Force Hit caster, linear and 3 directions OFF
- if Ability is linear or 3 direction : use Attacker coordinate instead of targeted tile
(in those abilities range = AoE, the Extra AoE will be deleted later)
- if Ability is not linear nor 3 directions : uses Attacker 0x178 data.(see Attacker 0x178 notes)
- if Attacker 0x178 = 0x06 : uses Targeted Tile Coordinates (Attacker 0x17a, 0x17c and 0x17e)
- if Attacker 0x178 <> 0x06 : uses Target ID to get his coordinates (Target 0x47, 0x48, 0x49)
Exits if Targeted coordinates are invalid
2nd part : spread AoE
- If AoE = 255 : Store AoE = 0x01 and Targeted = 0x00 in all panels
- If AoE <> 255 : - first nullify all panels AoE and Targeted flag
- Set Targeted panel AoE = Ability AoE + 1 (both elevation)
- if Ability is not weapon ranged
- Spread AoE on panels Calculate_Tiles_Hit_by_Ability (while spreading set panels 0x01 byte to 0x00)
- Check for vertical tolerance (nullify AoE off panels out of range) Check Vert Tolerance and if Tiles can be Chosen
- If Moldball virus, nullify AoE if panel as depth > 0 Moldball Virus Depth Check
** At this point - Targetable valid panels have their AoE > 0 and targeted flag (0x01) set to 0x00 **
3rd part : adapt AoE on specific cases
- if Ability do not hit caster : nullify caster panel AoE
- if Ability is linear : Nullify AoE of panels not lined up with Attacker and Targeted tile Linear/3-direction_AoE_Calculation
- if Ability is 3 direction : Same as linear, keep 2 other directions Linear/3-direction_AoE_Calculation
- if Ability ignore allies/ennemies : Check_Allies/Enemies_that_can_be_Targeted
- Test all units : - if Unit on panel is ignored : AoE panel is set to 0x00
- if Unit on panel is not ignored : panel 0x01 byte is set to 0x01 and kept this way
- Test all panels : if panel AoE > 1 set panel 0x01 byte to 0x01
4rd part : test all tiles : count targeted panel and activate "green panel" flag (tile 0x05 byte)
- if Ability Hits every team : - if panel AoE > 0x00
- if Tile is not selectable/targetable (tile 0x06 byte) - Tile 0x05 is forced without the 0x80 value
- if Tile is valid Tile is counted and Tile 0x05 Green Panel flag is set (0x80)
- if panel AoE = 0x00, matching Tile 0x05 is forced without the 0x80 value
- if Ability Ignores a team : - if panel 0x01 flag is <> 0x00
- if Tile is not selectable/targetable (tile 0x06 byte) then Tile 0x05 is forced without the 0x80 value
- if Tile is valid then Tile is counted and Tile 0x05 Green Panel flag is set (0x80)
- if panel 0x01 flag = 0x00 then Tile 0x05 is forced without the 0x80 value
Panel state after routine
- Valid Targetable Panels has their AoE > 0x00
- Panels keeps their 0x01 flags only if Ability ignores a team
- When ability ignore a team : Panels beyond range, may have their 0x01 flags = 0x01 and AoE = 0
Notes :
- AoE value is higher at the center and decrease while spreading. Panel with AoE = 0x01 are on the borders of the AoE
or at the end of the "beam" of a linear attack. This could be used to decrease damage or anything else.
The only exception is for Ability with AoE = 255 where all the panel has their AoE = 0x01.
Attacker 0x178 notes
In the actual table data location page this byte is known as reaction ID ?. - The value 0x06 seems to be related to Target specific ability (follow target) - The value 0x05 might be for Tile specific ability (cast on a tile, do not follow unit) Here are the notes i found on this routine page before formatting it. I'm not able yet to determine if it's accurate. *0x001a - Modified in (0074308) where value is set to 05 if Unit is under player control (ENTD 08) or if Unit ID = 2 (0x0168 of Misc Unit Data (0b7308)). I have no idea if 0x0168 is actually Unit ID and I suspect not (doesn't really seem to coordinate with Unit IDs in ENTD), but it is cycled through and changed constantly during the AI's decision making process. It could otherwise very well be the decision value or the AI derived Unit ID aka Battle ID? Otherwise 0x001a is usually 06. I don't know the significance of 04 (Miming action?), but 02 = Player Control, 01 = AI Control. I've only ever seen 05 or 06 when the process comes here. Perhaps if it's not 04, it doesn't come here at all? Complete guesswork on my part here, but 04 might be tied to Action Menu flags (If not Default/Elemental/Monster/etc., or any skillset type that doesn't normally take AoE, then don't even go to (0074308)? Anyways, 0x001a is important because the AI has to get the targeted unit, then determine it's X,Y. Player Controlled Units already have the X,Y loaded into the stack.
