Bosses - Gorre

partialfrom#296#297#303

Gorre (ccBoss05, boss05.cpp) is Outbreak's second phase boss: bossTbl row 4, bossFunc code 4, file x51. It fights beside two ccBoss05Brothers, each its own character (bossTbl rows 40 and 41) run from Gorre's frame the way Kyvia runs its core and gomoras (each a Boss of its own, taken out of its character for the frame and put back). Gorre itself is never on the command lists and never struck; the brothers are, and the three share one HP through SendMessage. The names and layouts are Infection's DWARF (Infection's gcmn carries the class, never entered; Outbreak's offsets match); the behaviour is Outbreak's code.

The constructor

ccBoss05::ccBoss05: SetBaseParam(ccGetBossParam(4)), Boss05AnmTbl; Kite's place less 500 on y; no body hit; cheatHP on. No ccEntryCmnd: Gorre stays off the command lists (nothing targets or affects it). Two brothers new[]'d, each Init'd 300 either side on x (m_posB, a plain world-space addend: the place is Gorre's plus it, no heading turn), its own row (40 or 41), boss05SlaveAnmTbl1/2, anmw on ANM_xx11wave, ccEntryCmnd. EntrySlave(0, 0) twice (OffExit, OnDraw, Order(0)). InitBossCamera(200, 1500): the ccBossCam constructor's MaxRenge (+0xd8, 1000.0) is left as it is (Fidchell's constructor alone sets its own, 600, after). ChangeAction(0), SetPatternMode(0).

A frame

ccBoss05::Main: CalcRealEx(0) (the base's CalcReal, then the protect gauge's picture on both brothers), CalcTargetInfo, the centre, the stop's count, hold set while either brother's is, Think, the party held while lockPlayer (and a broken protect's count run on), Move (no body hit), the broken protect's count handed to both brothers, Slave (each brother's m_dircB toward Gorre, then its Main), hold cleared. No PreDrawAnm and no Draw: nothing in Outbreak calls ccBoss05::PreDrawAnm (nor does its task, ccThBoss05: Main, then CheckExit), so Gorre's own body is neither animated nor drawn except in the Kerse's step 2, which forwards its clip and draws it at m_talkPos (gorre::body). The two brothers are what is seen of the fight.

ccBoss05::ChangeAction: the base's, then Order(act) on both brothers (whether or not the base took it), m_actSub* cleared.

Think by act (@1462; 9, 10, 17 and 19 the table's trap):

The patterns

ExecPatternIndex; 2-8 and 12 fall to the base's, whose ChangeAction is Gorre's through the vtable (the brothers ordered too):

The tables (boss05*ActTbl, 39, 47 and 26 words) hold pattern 10's operand as a -1, so each is its full size, not "up to the first -1".

The acts

• Neutral / Epitaph: turn to the target, the wait, SelectTarget(0), the next pattern.
• Wave (4, 13): both brothers untargetable and without a body; from frame 115 the camera's quake (15) while in shake range, at 115 a flash and a WaveShock at each brother; the brothers' own Wave ends it (msg 2).
• Kerse (3), seven steps (@1644): a target (type 11), the party held, SwitchLayer, the stage fader, the cinema (19), camera 3 (1500 off the target at height 50, looking at it at 200), m_talkPos 500 the other way; the brothers fade out (a fifteenth a frame) and undrawn; Gorre's own clip runs, sounds at its frames 0 and 75, from 80 Gorre fades (a thirtieth) into the FinalPhotonFlash at the target; 15 frames on the second brother's skill 19 there; once the flash is gone the brothers drawn and fading back; 15 on, the fader out; 15 more, camera 2, Gorre undrawn (OffDraw) and neutral (forbid 3).
• Talk (5) / Data Drain (6): a target (type 2 / 0), the party held, the cinema; at 45 the stream (71 / 72); once the menu shuts, the second brother's skill 20 on it and a flash (Talk) or EntryAffect 13 (Data Drain); the next pattern.
• Dash (7): the base's dash to dashPos at 50, a trail of both brothers, both held; within 200 or 121 frames on, the next pattern.
• Wander (8): a way drawn (ccRandF(pi)), 120 frames at 30.
• Escape (16): a quarter turn off the target's way, redrawn every 32 frames, at 100 then 30; the next pattern at 300.
• Chase (18): at a target (type 7) at 100; within 300 or 60 frames on, the next pattern; out of the arena (IsValidArea: inside 2500 plus the centre's x and y of 0), a dash of 500.
• Skill (20): one of @1777 (157, 158 the first brother's, 159, 160 the second's) by ccRand() & 3, started (effSkillStart) under the fader, camera 3 and the spell's cinema; once the start ends the caster's ccItemSkillCompel; 50 on the fader out; 15 more the next pattern.
• Tornade (21): a target (type 3), the party held, the brothers untargetable, the cinema (68), camera 3 1500 off the target; the brothers do the rest (msgs 5, 7, 6).
• Magic (22): one of @1672 by abs(ccRand()) & 3, the second brother's request at 15; 60 on the brothers back; 15 more, the next pattern.
• Drain (11): act 12 and the Epitaph table, m_patMode 2.
• Dead (14): no body; both brothers ordered dead and set 300 either side across the way to the centre; camera 3 3000 off Gorre at height 100, looking at it 500 up. The brothers' own deaths end the fight (msg 4).

Brother

Order(on): 0 and 15 a neutral (forbid 1); 3 and 5 act 15, a watch; 4 m_bWaveEnd cleared and anmw on the wave's clip first; anything else that act, forbid 3. Think has cases for 0, 4, 12, 13, 14 and 21 only: in any other act (Gorre's own, ordered along) a brother does nothing.

Move: m_posB stepped by m_moveSpdB along m_moveDircB, moved by m_moveVectorB (always (0, 0, 0, 1)), the place Gorre's plus m_posB, the base's speed on top.

• Neutral (0) / Epitaph (12): stopped or held, msg 3; else a turn toward Gorre and m_posB turned 0x3c8efa35 around Z (the Epitaph's turns first whatever holds it).
• Wave (4) / EpitaphWave (13): untargetable, no body; out at 50 past 500; 30 frames still (a sound, the Wave's only); half a turn round Gorre at 5 degrees a frame from m_prevPosB (a trail every fourth frame, or every sixth for the Epitaph's); the strike's clip (ANM_ex51act2/ ANM_ex52act2 by id, the Epitaph's ANM_ex5xact): sounds at its frames 15 and 35, from 40 the wave drawn (anmw forward, then at double speed) and skill 18 at 55; both clips over, the act's clip; 15 frames on, home at 50 to within 300, msg 2, targetable (and, the Wave's only, the body back and a turn to its way each frame).
• Tornade (21): facing Gorre; from 15 frames on a fade out, msg 5 at 0; from 15 on a fade back; then 211 frames of m_posB turned by m_fRad (from half a degree, quickening by m_fRadAccel to a quarter turn), a whoosh on 26 fixed frames, msg 7 at 120, msg 6 after.
• Dead (14): the dead effect at its place, off the lists; once the effect is out of the manager, msg 4 and OnExit (out, off the lists, no body).
• Affect: msg 0 (a drain only before its own Epitaph), then 5/6 stop, and a hit's shield (row 40 against ccSkillCheckType 0, row 41 against 1), number and mark.

SendMessage

SendMessage(br, msg), by msg (@2268); 2, 4, 5, 6 and 7 act only once both brothers' m_sendMsgFlag[msg] are set, and clear both (6 leaves them set: the next Tornade's first report ends it at once):

Msg 0, by type: 1 and 3 (a hit) take the three's one HP - under cheatHP a tenth, never under half, and the broken protect shared (the struck brother's count is Gorre's, a fresh break of 300 breaks the other's, its gauge Gorre's and the other's); at 0 the boss camera off (OffBossCamera), the party's conditions cleared and the party held, the brothers untargetable, the music out and Gorre's Dead; else, if Gorre's own last affect type is 1 (never: nothing reaches Gorre), a hit act. A hit with the gauge at half its maximum turns to the Super table. 7 and 9 heal the three. 13 is the Drain (ChangeAction(11, 2), cheatHP off). 21 gives both brothers row 4's stats and Gorre's own param, the three at 6000 HP, their gauges -1.

Tables

tables::combat: gorre_normal, gorre_super, gorre_epitaph (each its full size), gorre_anims, gorre_brother_anims/gorre_brother2_anims, gorre_skills (@1777), gorre_magic_skills (@1672), gorre_tornade_skills (@2074). @1261 (157, 158, 160) is read only by Infection's pattern 10; Outbreak's skips it.

Checks

tools/test_battle_gorre_rs.py (battle_probe's gorre) runs ccBoss05::ccBoss05 and Main (each brother's Main under it) natively against the port, frame by frame, with scripted affects on Gorre and on both brothers (hits, drains, heals, the drain's 21), the menu and the camera; compared: Gorre's and each brother's generic fields, m_posB, the gauges through each character's own param, the lists, MaxRenge, the effects alive, the party, the calls, the menu, both generators. 0 mismatches over bulk 100 from 9900, 20000 and 40000 (every act but 1, 2, 8, 11 (within a frame) and 15; 1 and 2 are unreachable, see above). outbreak_story_survey finishes event 218 (PINEY_SURVEY_GOD=1, 150,000 frames): the shared gauge broken, a brother drained, the three down.

Unknown

• effResistantShield's own picture: the brother's shield is shown (Out::Shield), its vector tweak (x halved, z times 1.3 plus 200) not.
• After msg 0's 21 the brothers share Gorre's param in the game; the port writes the same values to all three but keeps three: a later change to one gauge (none happens in the fight once it is -1) would not reach the others.
• ccBossEffFinalPhotonFlashCreate's picture (its life, 72, is measured).
