Reintroduce apps/arcade and the ten game crates that were ripped out of
the fork (assets, audio, blocks, coedit, gen, net, pkg, render, script,
session), from makepad-internal/dev. Reconcile against the fork's layout:
- makepad-game-sim/math come from the fork's existing libs/sim + sim/math;
the copied internal libs/game/{sim,math} are dropped and the kept game
crates plus arcade point at ../../sim and ../../sim/math.
- arcade AI is rewritten off the removed makepad-ai agent API onto the
makepad-ai-hub headless ChatProvider worker (example/cad pattern):
AiWorker{send,cancel,poll}, ai_worker_loop driving
ClaudeApiChatProvider(ClaudeCli), AiWorkerEvent availability/delta/
done/error mapped into the chat feed and authoring land_edit, with
main.rs send_message/cancel_request/event-drain rebuilt around it.
- the game-script sandbox is adapted to the fork's jailed splash storage:
every isolate gets mod.fs = splash_storage jail; splaes splash_storage
set_root_for_heap is now public so the ScriptHost (or Splash) can grant
a per-game jail root. ENT font: build.rs/dispatch.rs entities fill new
fork sim Entity/Part fields via ..Default::default(); world_raycast now
borrows mutably and returns the material id.
cargo check -p makepad-arcade and the game + arcade test suites pass.
Point the workspace at libs/asset and libs/render. Drop Arcade
frontend, gamemaker, rig, pack registry, physics, and the old
libs/game gameplay crates. Those live in the private sandbox repo.
THE FINDING THAT CHANGES THE PREMISE: "1 rigged model in 4,442" was measured
with the BROKEN GLB probe (the gLUF magic bug). With the probe fixed the
library holds 36 rigged models across three rigs:
41 joints — 9 KayKit heroes + undead, up to 95 clips
7 joints — 22 KENNEY civilians (male/female a-f, orc, human, archer, shop
employees, skaters, soldiers), 32 clips
6 joints — 5 Kenney platformer characters, 25 clips
So a village can be populated with 22 visually distinct civilians TODAY, with
no third-party pack at all. Every conclusion drawn from that probe before it
was fixed needs re-checking, not just this one.
KayKit: 9 characters fetched (Adventurers + Skeletons), pinned by commit +
sha256, 37 MB, gitignored. CC0 verified by READING LICENSE.txt at each pinned
commit, recorded in the script header and CREDITS.toml.
THE SHARED RIG HOLDS ACROSS PACKS, proven rather than assumed: hashing the
joint-name list of all nine files yields the SAME digest — 41 joints, same
names, same order — despite two separate repositories. Skeleton clips are a
strict superset (95 = the adventurers' 76 + 19 undead extras: awaken,
resurrect, spawn, taunt). So a clip authored for the knight plays on the
skeleton warrior and one animation path drives the cast. A test pins this,
including that both packs are present, so a version bump cannot silently break
it.
The texture trap that cost the Kenney fetch three attempts does NOT apply:
KayKit GLBs EMBED their atlas (image/png in a bufferView), verified by parsing
all nine.
tests/rigged.rs parses all 36 rigged models through makepad_game_render::skin
— the loader the app actually runs — and asserts the index's joint and clip
counts match it. Deliberate: the index's own probe was wrong for the entire
library once and survived because the fixture encoded the same error.
find_cast groups by JOINT COUNT rather than pack, because the valuable fact is
cross-pack interchangeability. Cast states are the INTERSECTION, not the union
— advertising a state one member cannot perform is worse than a shorter list.
Added the state words the skeletons needed (spawn/resurrect/taunt/use):
Skeletons_Awaken_Floor previously matched nothing, so "an undead that rises
from the ground" was unfindable.
One bug found in its own work: casts_to_json emitted a doubled closing brace —
malformed JSON that still looked fine in a log. Fixed with a structural test.
