The user reported that the first login flow was missing: Orca's walkthrough and the trip to the first field. In the game this is event 2, "MG0020 TEACH_T". It is 57 messages, two tutorials and a scene change, played in Mac Anu the first time Kite logs in. The event VM was ported and checked in 40, but only the desktop (41) and the top page hosted it. An agent and two helpers built the field's host and the pieces event 2 needs.

How it plays

piney-game --mode world now builds the event task as a new game reaches Log in:

• the boot's ccStartEvent(1, 0);
• the desktop's passes, with event 1 played until mails 4 and 5 are read;
• the board's;
• Log in's disable.

The session's own Log in hands over its real VM. From there, by frame:

The runtime stops at the scene change. The window title names the area and its words (server 0; words 0, 13, 26); the field is the next piece.

What was built

• The field host (field_host.rs). piney-event's Host for The World covers:

  • messages, announcements and menus through piney-fieldui;
  • the camera and characters through piney-world;
  • sounds and voices, the fader, the party, and the gate lists in the save.

• The phases. The VM runs at the set-up's phases 0, 2 and 4, then once a frame before any other task.

• The event camera (evcam.rs):

  • camz_set, camz_speed and camz_move;
  • camera, the character camera;
  • the hand back to the player's camera.

• The characters' event commands.

  • pc_act, including Kite's TransferIn;
  • pc_face with a gradual turn;
  • pc_turn;
  • pc_mode;
  • the AI's manual and remote switches.

  These work for Kite and for Orca as a fellow (ai.rs, party.rs, and changes to fellow.rs and player.rs).

• One party. piney-world's ccPartyManager is the only party. Both the event's party_add and the field UI's AddMember go to it.

• The fader. ccScFade's EntryFade, ContinueFade and the SendPacket counting.

• ChangeScene. The story areas are read from the executable: 126 eventAreaInfo records with their word ids (story.rs).

• A VM change. scene now waits (Wait::ChangeRequest) after change_scene. In the game, ChangeRequest(6, 7) puts the event task to sleep inside the instruction. A host that does not model this answers at once, so the VM's existing checks are unchanged.

Checked

• The event camera. tools/test_evcam_rs.py: 6 tests, 2,643 instructions and 55,433 frames, 0 mismatches. It compares the whole ccEvCamCtrl, the camera structures and matrices, and Kite.

• The characters' commands. tools/test_evchar_rs.py: 6 tests. It runs 39 scenarios (311 instructions through ccEvent::Execute, 12,330 frames), 0 mismatches. It compares Kite and Orca frame by frame:

  • position, heading and acts;
  • cloak and transparency;
  • list membership;
  • the AI's switches and turn.

• The fader and ChangeScene. tools/test_field_host.py: 592 fader calls and 122 ChangeScene states against the game, replayed by the Rust tests from a fixture.

• The story areas. All 126 match the values the game's own functions gave in the VM fixture.

• The whole event. event_2_plays_to_the_scene_change plays event 2 headless from --mode world's state with a scripted pad. It asserts:

  • all 69 host calls and their frames;
  • the end frame, 2295;
  • the voices;
  • the gate, word and member bits in the save;
  • the party [0, 2, -1];
  • that the VM ends asleep inside scene.

  a_new_game_reaches_the_world_with_event_1_done checks the starting state.

• Re-run in a clean worktree. The event camera, characters, field host, event VM, world, field UI, top page and desktop suites pass. So do the workspace's tests, clippy, fmt and the docs check.

• Shots. Orca waiting at the plaza as Kite arrives, his first line, the member address notice, the HUD with Kite's and Orca's panels, the fade, and the gate tutorial's keyword screen.
