claude	e0c1e0d5c6	Stage 5: bosses that move, attacks that warn, and a second boss ... Boss movement is a property of the PHASE, not of the boss -- a fight that stands still and then starts hunting you is one boss with two phases. Four modes (STATIC, ORBIT, CHASE, WAYPOINTS) handled generically in SimWorld._move_boss, so a boss that moves is still data. BossDef.stationary is gone rather than kept beside the phases: a flag claiming the boss stood still while a phase walked around would be a second source of truth and the wrong one, so moves() is derived. CHASE holds a distance instead of closing, because a boss standing on top of you is a boss whose bullets cannot be read. Waypoints are fractions of the arena so one phase works in rooms of different sizes. Every mode is speed clamped in one place -- ORBIT computes an absolute destination and would otherwise snap onto its circle on the first tick -- and movement slides against geometry so a boss cannot walk through the pillars its own arena was designed around. The room clamp moved to after movement, where it is finally load-bearing. It was a no-op while every boss stood still, which is exactly when an invariant is cheapest to establish: boss rooms deliberately do not lock, so walking out is always an escape, and that only holds if the boss cannot follow. TelegraphedStrikeEmitter marks spots and fills them a moment later. The moment between is the feature: a burst at your feet is a coin flip, the same burst with a second of notice is a question. It stays stateless like every other emitter -- they are shared resources and two bosses of the same kind must not stomp each other -- so strike positions are derived from the volley number and a test asserts the burst lands where the marker promised. Markers are drawn through fog and through walls, unlike everything else in the view, because a warning you cannot see is an unavoidable hit with extra steps. The Cantor of the Vault fights in the choir vault: static, then a four-corner circuit, then a chase, then orbiting while marking. It exists to prove the format stretched, and a test asserts it uses both new mechanisms. Which boss a run has now comes from its SEED rather than its depth. Depth is a dev flag nothing in play raises, so the arena was keyed to something no player can change and the second boss was unreachable in an actual game. Two things found while finishing: - tools/export_content.gd had a hand-maintained boss list and had already gone stale, silently not writing the Cantor. Content.ALL_ENEMIES and ALL_BOSSES now feed the export tool, the renderer and five tests that each kept their own copy. - diag_loot failed intermittently after another diagnostic. Taking over from the bot cleared its input queue but not its HELD input, so a starved server coasted on the bot's last movement vector for half a second and walked the player off the item it had been placed on. The press arrived correctly, which is why "the press reached the simulation" passed while everything it should have caused failed. check.sh clean, 409 tests, SMOKE PASS (19 assertions), all four diagnostics green.

claude	ff5e527ad4	Fix black wall tops, pillar art, player anchor, and whole-sheet bullets ... Bullets rendered as the entire sprite sheet, which was the clue that named the cause: a MultiMeshInstance2D cannot show a sub-region of a texture. Its mesh UVs run 0..1 across whatever texture it is handed, and an AtlasTexture does not help -- the draw resolves to the underlying atlas and the region is discarded. Frames are now pre-sliced into 32 standalone 16x16 textures at startup, so each frame is one texture assignment per kind and no region is involved. My previous two attempts fixed the atlas contents while the renderer was structurally incapable of showing one cell of it. Black voids above walls: wall_top_mid has 12 of its 16 rows transparent. It is a cap meant to be laid over a wall, not a tile, and drawn alone it was three quarters nothing. Floor is now drawn beneath every tile so transparency shows ground rather than clear colour, the wall face is drawn from the opaque wall_mid, and the cap is overlaid only where open floor lies above. Pillars used a wall segment and read as stray blocks; they now use the column tile, which looks like something you walk around. The player hitbox appeared at the head because it was: the knight occupies rows 8..27 of a 28-row cell, so anchoring on the cell centre put the draw origin about 4px above the body's centre. Added a per-sprite anchor offset that cancels it, with a test that recomputes the offset from the art so a re-cut sheet fails rather than silently misplacing the character. Tests pin the two tileset facts that caused this: the cap is mostly transparent (so it may never be drawn alone) and the wall face is fully opaque (so it may). 166 tests. check.sh, test.sh and smoke.sh pass.	2026-09-04 00:22:01 +02:00
claude	afe76c22ce	Fix bullet atlas, animation speed, sprite flip, fire rate, silent shots ... Bullet sprites were wrong because I read the pack's layout backwards. Each of its 8 PNGs is one ANIMATION FRAME, and a column within a file is a COLOUR variant -- so walking columns cycled the palette while the shape sat still, and the rows I picked were in a region of larger multi-cell sprites, which is the scattered debris that showed on screen. tools/build_local_assets.py now composes a proper atlas: 8 frames across, one row per SimConfig.KIND_*. Animations ran at whatever the machine's framerate was, because they counted _process calls. At 240fps that is four times too fast on its own, before the requested halving. Both actor and bullet animation are now driven by elapsed seconds, so they look the same on any machine. The knight shifted sideways instead of mirroring: a Rect2 with negative width does not flip, the draw call normalises it, so the sprite kept its orientation and jumped right by its own width. Mirrored through the canvas transform about the sprite's centre instead. Shots were silent when a bullet spawned inside an enemy. The sound rode on BULLET_SPAWN, which is deliberately suppressed for a bullet resolved and removed within the same tick -- so no event, no sound, and this got more likely the closer you stood. Firing is now its own event (PLAYER_FIRED): the shot happened whether or not a bullet survived to be replicated. Protocol 3 -> 4, because inserting mid-enum shifts the wire value of every event after it. Fire cooldown 7 -> 14 ticks (4.3 shots/sec). Licence question 2, confirmed verbatim: the paid tier DOES grant commercial use ("You may use these assets in personal, commercial or non-commercial projects"), but its next sentence still forbids redistribution "no matter how much you modify it". Paying moves these from local-only-and-non-commercial to local-only-and-commercial; it never makes them committable. Only replacing them with permissively licensed art does that. Question 3: CREDITS.md now credits every pack, including the two whose licences do not require it and the unused ones in considering_dont_use_yet/. 158 tests. check.sh, test.sh and smoke.sh pass.	2026-09-04 00:03:04 +02:00
claude	3586555aea	Remove non-redistributable art from the repo; record licence terms ... Researched the licence at each of the four itch.io sources. Two of the four forbid redistribution, and publishing a repository containing them is exactly that, so they are out of the tree. 0x72 DungeonTileset II CC0 1.0 commercial ok, no credit required Helton Yan Pixel Combat CC BY 4.0 commercial ok, CREDIT REQUIRED Fire Pixel Bullet 16x16 custom non-commercial, NO REDISTRIBUTION 750+ Effect and FX Pixel custom non-commercial, NO REDISTRIBUTION Both bdragon1727 packs state verbatim: "You cannot do: Resell / redistribute this asset." The FX pack's paid tier is no better for this purpose -- "You can NOT re-distribute the file, no matter how much you modify it" -- so paying does not unlock it and neither does editing the art. bullets.png and impact.png therefore move to assets/local/, gitignored. Art.bullets_texture() / impact_texture() load them at runtime and return null when absent; the bullet renderer falls back to the generated dot it used before, tinted per kind so bullet types stay distinguishable. Nothing there may be preload()ed -- preload resolves at compile time and would fail the build on every machine without the files, which is every clone. Verified both ways rather than assumed: with the files present the game uses them and no fallback triggers; with them moved aside, 156/156 tests pass and the game runs clean on the generated dots. Added CREDITS.md, because Helton Yan's CC BY 4.0 makes attribution a licence obligation rather than a courtesy. A file in the source tree does not discharge it once the game ships -- an in-game credits screen is now a tracked todo, and flagged as a licence requirement rather than polish. NOT addressed here, and it needs a decision: these files remain in git history at 9fa2e26. Removing them from the tip does not remove them from a clone. If this repo is ever made public, history has to be rewritten (git filter-repo) and force-pushed. Also, both bdragon packs are non-commercial in their free tier, which conflicts with the stated Steam goal -- either contribute for the commercial tier (still no redistribution) or replace with CC0 art, which would solve both problems and let the assets back into the repo.	2026-09-03 23:52:41 +02:00
claude	9fa2e260f2	Replace placeholder rendering with real sprites and audio ... Terrain, actors, boss and bullets are sprites now, and four sounds play off server events. 548KB total across seven files, out of 3.9GB of source packs. - src/view/art.gd holds every atlas rect and sound path in one table, copied from the 0x72 pack's own tile_list. Scattering coordinates through draw calls would make re-cutting the atlas a hunt, and a wrong rect invisible. - Bullets get one MultiMesh per kind rather than one overall: a MultiMeshInstance2D carries a single texture and each kind needs a different region of the sheet. Four draw calls, no custom shader passing UVs through per-instance data. - src/view/sfx.gd is a 16-voice round-robin pool. Bullet-hell fire rates mean sounds overlap constantly, and identical sounds landing within two frames are collapsed so a ring hitting eight bullets is a bang rather than clipping. Every sound is triggered by a server event, never a local guess, so what you hear matches what happened. Audio was converted, not copied: the pack ships 24-bit/96kHz masters averaging 2MB. Downsampled to 16-bit/44.1kHz mono, silence-trimmed, and the shoot sound hard-capped to 0.30s -- it came out at 2.03s, against a fire cooldown of 0.12s, which would have smeared held fire into noise. tests/unit/test_art.gd checks what cannot be eyeballed here: every atlas rect lands inside its texture, every animation frame of a strip fits (the last frame is what runs off the sheet, not the first), there is a sprite per bullet kind and per enemy visual, and no sound is long enough to stack badly. A wrong atlas coordinate does not error -- it silently draws the wrong pixels. Licence sources recorded in docs/ASSETS.md now that they are known. All four are free versions and four rows still say "confirm at source": free itch packs vary on credit and commercial use, and there is no credits screen yet. 155 tests (was 146). check.sh, test.sh and smoke.sh pass.	2026-09-03 23:43:13 +02:00
