This follows 263. Event 115 goes through field 13, and event 107's arena fight needed a look. Both lead to the same finding: Mutation's story fights three bosses the port has not got.

Area 13: EVENTAREA01

Field 13 is EVENTAREA01 (MUT gcmn 0x00414110 constructor, 0x00414c00 Draw). Its parts:

• The scene. se1_1: EA_MODELTABLE01's seven rows (a floor, five type-2 pieces, one type-3), EA_OBJTABLE01's one animated object, and bg[0] CMP_se1_1bg1 with fog off.
• The lights. The light animation ANM_se1_1bac1a and eventarea01Light's eleven rows: one distant light, then ten omni.
• The rest. Four BLT groups. Fog (150, 4000, 0, 80, 0x1e1e1e). The start is DMY_marker_ev01, its w the dummy's turn about z.
• Seven glows. EFF_se1_1ef1, Init with fog, then PRIM's fog bit cleared, one at each of DMY_effpoint01-07. For each, the constructor draws a frame, a wait (30-129) and a flicker count (1-15) from fieldrand.

Draw is:

1. DrawBG.
2. On objLayer: DrawObj2 (type 3), DrawObj (type 2), DrawFloor (type 1) and the type-0 rows.
3. On effLayer: each glow.

A waiting glow counts down and draws its animation's next frame. When its wait runs out it flickers: a random frame for count frames, then a new wait and count.

The class is built like a town, so the port builds it on town::Base. A new Base::read_volume reads the volume's own tables; Base::read is Infection's as before. StorySprite gains fog, so these glows draw without fog but keep the depth test (flare drops both). evarea01::tests::area_13 checks the pieces, the lights, the collision, the glows' first frames and the draw.

A bug in area 43's map

Area43's draw filtered DrawPass::Obj for its "pass-0" models. Pass 0 is DrawPass::Other; Obj is type 2. The map drew nothing. area_43 now also checks that the draw puts something out.

The pilot

• Talks in a field. Event 115's field 13 waits for six talked_tos. Each is a repeatable block that sets a status, and block 21 wants all six. The add_targets stay on the list after a talk. So the pilot walks (path_to over the place's collision) to each event NPC not yet spoken to here, presses OK once he is the command target, and counts the talk once the event's menu_ban shows. FieldWorld gains event_targets, command_target_code and place_hits.
• Board posts rank below the story's wants. In event 108 the pilot logged in to Dun Loireag, logged out for an unread post, found the board held on the top page (operate 7), and logged in again. ccStartThEvent resets the event manager in town, so the hold does not show there. Mail still comes first (events wait on mail_got); posts now come after the wants.
• Data Drain. A boss whose protect is broken (pp_count frames left) is drained: Skills, page 5, skill 2.
• mutation_whole_story runs a new game to event 116's end and prints each story event's end as it comes.

The bosses

In event 107's arena the foe list stayed empty: the port starts only Skeith. ccBossEntryStart(code) (MUT gcmn 0x00470c40) starts ccThBossEffect and bossFunc[code] (MUT 0x006192c0, 16 rows):

0 Boss01 (Skeith)   1 Boss02 (Innis)   2 Boss03 (Magus)   3 Boss04
4 Boss05            5 Boss06           6 Boss07           7 Boss08
8-11 none           12-15 Kyvia01-04

Mutation's story enters three of them with entry type 7:

Their size on Mutation:

• ccBoss02: 54 functions, 38,616 bytes.
• ccBoss03: 70 functions, 38,248 bytes.
• The kyvia classes: 98 functions, 74,448 bytes, shared by the four Kyvia fights.

Skeith's ccBoss01 is 26 functions and 15,064 bytes. EVENTAREAB8 (fields 9-12: 40 FLOATROCKs, 25 clouds, a disc that carries the party under WORLD_MAN::SetTransMode) is Kyvia's stage and goes with that port.
