Entry 92

What Infection's events 1-99 still need from the hosts, and the town's trans, frame rate and overlay

The story starts only reach events 3-14 (82). To see what the rest of Infection needs, the host methods its scripts can reach were counted statically.

How

• The scripts. tools/evscript.py dump gives every script. Events 1-99 are Infection's own: groups M1 and S1, the main story and the side events. They use 124 distinct instructions.
• Instructions to host methods. Each instruction's Host calls come from piney-event's vm/exec.rs.
• What is still missing. A method counts when it still runs the trait's default in a host.

This over-counts. An instruction counts for every host, even when its block only ever runs in one place (a dungeon's room in the town's list, say).

Where Helba is

• In Infection (events 1-99), she only appears by name: event 24's Apeiron warns of her by name.
• In the later volumes. She is placed (entry type 2 code 17) and talks only in events 101 and up, the M2 to M4 scripts, which are Mutation and later.

What remains, by host

• The town (field_host):
  • add_spc_item, and item_get_menu / item_get_menu_end (the item-get window). These are in 12 or more events; the combat agent is writing the field's, and the town will follow them.
  • piros_colour (event 22).
  • room, which is only in dungeons.
• The field and dungeon (area_host, the combat agent's): the same item methods, and:
  • npc (8 events);
  • party_remove (5 events, event 11 among them);
  • room, trans and piros_colour.
• Not a gap. generate_area runs only when a story start replays virus_core; while playing, the instruction does nothing.

Done here, for the town

• trans_off / trans_on (cases 161 and 162, main 0x001b2248 and 0x001b22f4): the character's transDist (+0x90), the near fade. The type's bit picks the list: 2 a party member, 3-4 an NPC, 5-6 an enemy (none in a town). They are World::set_trans, used on NPCs by events 14, 27 and 29.
• frame_rate. The scripts' SetFrameRate is kept by the town host, and the town mode runs at it (event 31).
• overlay. Nothing to load, as on the desktop (91).

Checked

The workspace's tests, clippy, fmt and the docs check pass.
