Bosses - Kyvia's second fight

partialfrom#304

bossTbl row 13 is Kyvia's second fight: ccBossKyvia02 (kyvia02.cpp), bossFunc code 13. The English table names rows 12 and 13 both "Cubia", its name for Kyvia; the core rows are "Cubia Core". Outbreak's event 211 enters it on field 10's disc (entry type=7 code=13, then absent type=7 code=13). It is the first fight's code with its own numbers, a second stage of the disc and a fourth attack, the thunderbolts. Names and layouts are Infection's DWARF; the rules are Outbreak's code.

Where it comes from

bossFunc[13] (0x004d5870) makes new ccBossKyvia02(2) (0x29740 bytes) and runs its Main (vtable +0x1c, 0x004d7300) until CheckExit, as the first fight's task does. Outbreak's layout is Infection's with one byte more at +0x29350 (the cinema flag, Mutation's +0x295f8 in the first fight): the three pointers after it move 4, the rest 0x10.

class           size     rows (bossTbl)
ccBossKyvia02   0x29740  13 (6000 HP)
kyviaCore       0x295a0  34/35 by attribute at level 2 (2000 HP)
kyviaGomora     0x295f0  20-23 by attribute at level 2 (1400, 1200, 1200, 1300 HP)

What differs from the first fight

Everything not in this list is the first fight's code (Main, Think's switch but act 6, SwitchDeadCheck, SetBPos, Slave, EntrySlave and DeadKyviaVoice are the same code; the core and the gomoras are the same classes, at level 2).

  • The constructor: file x02, clip ANM_ex02nut0, the path's dummy OBJ_dummy3_3, DiscMaxLV 2, ExARGB 0x70808080, CoreInit(2), SwitchHp a fifth of the core's HP. At each rise CheckDiscMove reads the core's MaxHP again and makes SwitchHp a seventh.
  • Two stages. After the core's first death CheckDiscMove counts 60 frames: at 1 the quake (20, 20, 20), ExARGB and the player held; at 20 the ride's camera; at 40 the colour 0x50808080; from 41 the quake and SE 56 each sixth frame; at 60 the player free, DiscLV 2, EVENTAREAB8::Move, AtkPatMode 1. The disc rides on and the core rises again. Its sounds are at the disc, and the ride's camera looks at the disc itself (the first fight's 150 over it).
  • The attacks (SwitchActionPattern): 1 the arm (cinema 36); 2 the thunder of kind 0 on the first stage (46), else the beams (37); 3 the thunder of kind 1 on the first stage, back to 1, else the meteors (38); 4 the thunder of kind 2, back to 2. Boss skills 36, 37, 38 for the first fight's 33, 32, 34.
  • The smokes (CheckDmgSmokeEff) only on the last stage, 1000 up and 300 back. DmgGp[k] past its four reads DeadGp, then CamRotX (0.26): a fifth smoke fills DeadGp and there is no sixth.
  • The numbers: the hit's camera 650 back, 1100 up, the eye at -900; the arm's camera at 4500 (first stage) or 3500 and the first stage's quake (30, 40, 60), no SE 40 at the blow; the beams from 550 back and 1200 up, tilted 0.35 and eased to 2300, the quake (50, 50, 100) as they land; the meteors with stream 73, 550 back and 1100 up, the eye at -2800, a quake (20, 50, 80) at 60. The death: the smoke at x -50, 630 back and 1200 up, x 5 more a frame for 10 frames, the quake (30, 30, 20), the blur 1.03; its cameras at 70 (0x50808080, 1.02, 350 back, 1000 up, the eye at -900, turned |ccRandF(1)|) and 150 (500 up, the eye 2800 back and 1000 up, turned -|ccRandF(1)|).

The thunderbolts

ThunderboltAtk (act 6): once the core and gomoras rest (GetActNum) they fade out, the stage darkens (BeginStageEffect(0x64000000, 15, 15, 32277)), the player is held and the quake is (30, 30, 20). The members' bolts (Sdat) are 3 strokes over 50, 2-4 wide, tilted 0.5 plus up to 0.9. By ThunderType:

kind  frames  disc's bolts           the rest
0     90      3 over 100, 1-4 wide    a bolt on each member, smoke under it
1     90      4 over 550, 2-6 wide    a bolt on each member
2     120     15 over 450, 3-12 wide  the camera 3800 overhead (mode 5)

The build-up (ThunderSound, raising actCount) flashes at 10, 25, 30 and 50 and at 80 lets the bolts fall; kind 2's camera is the active one's place moved a little, looking 10 higher. The strike (ThunderDmg) deals boss skill 45 or 46 round the body five times and at ThunderTime (with flashes, SE 68 and 39), the quake by kind and at half-time, a thunder note each fifth frame (ccRand() % 20). 30 frames on, the core fades back (mode 6 for kind 2, 4 otherwise), the stage lightens over 35 frames.

A bolt (ccBossEffThunderbolt) has Num strokes: each from a point within the range (UnitPoint: turned ccRandF(pi), range - ccRandF(range / 10) out), 10-17 segments of CMP_x012 (SetBreakPoint: abs(ccRand() % 8) + 10), each 200 long, turned ccRandF(pi) about z and DefaultAngle + |ccRandF(RandAngle)| about x, drawn anew every frame: a stroke draws ccRand() for its width, two ccRandF(pi) it never uses, the turn and three ccRandF(RndPoint) for its start. The disc's bolts are raised 500 (the offset the caller writes after Create) with a smoke on their first draw; the effect ends after Time + 1 draws.

The core at level 2

SetCoreBaseParam(2, attr) takes rows 34 and 35; each call while the core is dead (DeadFlg, its ResetData) adds 3000 to both rows' maxHP in the table, for good, so the second stage's core has 5000 HP whichever attribute it takes. The gomoras take AllGomoraList_2[0] (3 3 3 - -, 3 3 3 - -, 0 3 3 3 -) and after the core's death ListStepUp(1) gives AllGomoraList_2[1] (1 3 3 3 -, 0 3 3 3 -, 0 0 3 3 1); level 2's rows and attack times are the first fight's code.

The port

piney_battle::boss::kyvia with Fight::Second (kyvia::new(cx, fight)), kyvia::thunder (the attack and Bolt, whose Draw the manager's pass runs for its ccRand draws), KyviaData::gomora_lists_of (kyvia_gomora_lists_2, kyvia02_anims in the combat group) and Core::row_hp. piney_world::combat::boss starts code 13 with x02's CMP_trallex02, CMP_trall2 and CMP_ex01gom2. The bolts have no picture yet (Bolt::segments holds each frame's).

Checks

PINEY_VOLUME=outbreak tools/test_battle_kyvia_rs.py runs Outbreak's ccBossKyvia02(2) natively against battle_probe's kyvia 2, as the first fight's harness does (its "Checks" in the first fight), with Outbreak's unnamed functions by address, the disc riding on for a case's frames after each Move, bossTbl restored for each case, the thunderbolts run natively (their clump stubbed) and compared by slot, EntryFlash, ccSeOnNote and the stage fader's calls compared, and the second fight's members and thunder compared each frame. 130 cases (405,579 frames) agree, reaching the body's acts 0-6 and 14, the three thunders, the core's two deaths. PINEY_KYVIA_FIGHT=1 runs Outbreak's copy of the first fight: it agrees with the port as Mutation's does. piney-battle's boss::kyvia::tests hold the second fight's make-up, its first stage's thunder and a bolt's life. outbreak_story_survey plays event 211 through (PINEY_SURVEY_GOD): the first stage's core down near frame 16,500, the second's near 22,000, the event done.

Unknown

  • Kind 2's camera: cameraGetPos, cameraGetRot and cameraGetView of camID are taken as the boss camera's; the harness answers all three from the case.
  • The bolts' picture and the particles are named, not drawn.
  • Whether a retried fight meets the rows as the disc has them: the game keeps the core's added maxHP in bossTbl, the port only for the fight (Core::row_hp).
