A new game, framework/games/rpgbattle3d.js: a 2.5D JRPG duel — a real 3D arena rendered with a fixed 3/4 camera, two skinned KayKit Knight instances (hero tinted blue, enemy red), and a classic command-menu turn loop. - Asset: KayKit "Character Pack: Adventurers" Knight by Kay Lousberg — CC0 (public domain), committed under assets/vendor/kaykit-knight/ (+ LICENSE + CREDITS). ONE model is baked and instanced twice (hero + tinted enemy) to stay in the soldier-class memory budget (the baked module is 0.64 MB, Fox-class). - Bake: framework/bake/bake-gltf.ts gains a clip allow-list (asset packs ship dozens of clips) + bakeRpgHero() baking only the 5 combat clips (Idle, Walking_A, Attack, Hit, Death) at 128px / boneLimit 8 -> assets-rpg-hero.ts. - Combat (deterministic, ctx.rng + frame timers): INTRO -> PLAYER (command menu) -> WINDUP/IMPACT/RECOVER -> ENEMY (AI) -> ... -> VICTORY/DEFEAT. Stats (HP/MP/ATK/DEF/SPD), SPD turn order, Attack / Power Strike (MP) / Defend / Potion, a damage formula with seeded variance + 12.5% crit, floating damage numbers, attacker lunge + target hit flash, HP/MP bars + nameplates drawn over the 3D pass. - Golden: framework/test/golden.ts gains a deterministic rpgbattle3d SPEC; the .dc3d draw-list golden captures the skinned characters (the software oracle is vertex-colour only, so the .png shows arena + HUD; WebGL/PSP show the models). bun run test green (golden + .dc3d + cross-host button contract). Verified in WebGL: hero left / enemy right facing each other, Power Strike lands a crit, HP/MP update. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Flashy melee hit effects for rpgbattle3d, built on a new engine feature. Engine — additive blending for the 3D layer (it had only opaque rendering, so cutout sprites washed to white blobs): - g3d.ts: OP_SET_BLEND wire op (0x0008) + CommandEncoder.setBlend(); Material.blend='add'. - scene3d.ts: brackets additive nodes with OP_SET_BLEND in BOTH paths — the OP-stream emit() (web/raster) and the native walkDynamic() (PSP, routed through the post stream). - web/engine.js: gl additive (blendFunc ONE,ONE, premultiplied) + depth-write off. - runtime/src/gfx3d.rs: sceGuBlendFunc(Add, Fix, Fix) + depth mask off on the PSP host. - runtime-3ds + contract.ts: OP_SET_BLEND declared for cross-host wire parity (3 hosts, 16 wire constants, contract green). raster3d skips it (oracle ignores textures anyway). VFX: - bake-vfx.ts: bakes CC0 sprite sheets into PREMULTIPLIED RGBA frames (so additive reproduces the soft glow). assets-vfx.ts = VFX_BOOM (22f) + VFX_SPARK (9f). - Assets (CC0, committed under assets/vendor/vfx/ + CREDITS): StumpyStrust "Explosion Sheet" + kurohina "Spark effect". - rpgbattle3d.js: a camera-facing additive billboard plays the explosion at the struck fighter on IMPACT (bigger on a crit), plus hit-stop (FSM freeze), a shake bump, and a screen-edge flash. Verified gorgeous in WebGL (a crit fireball glows over the scene). bun run test green (golden + .dc3d + wire/button contract). Deterministic: VFX timing is frame-stepped, hit-stop is fixed-length.

…mic-node registration Partial fixes toward the additive hit VFX rendering on PSP (works on web; renders as a white box on PSP). NOT yet resolved — development paused here. - bake-vfx: VFX frames baked at 64x64 (power-of-two; the PSP GE requires pow2 textures — 48px rendered white). Web is unaffected (handles NPOT). - rpgbattle3d.js: the VFX billboard stays VISIBLE and is hidden via scale=0 between hits, so the PSP native buildFlat (which walks once) registers it as a dynamic root; quad gets a normal so GE lighting renders it deterministically. After these, the node DRAWS on PSP but still as an untextured/unblended white quad — the native post-stream rigid textured+ additive draw path needs deeper work. bun run test green (web golden + .dc3d + wire/button contract). See the PR description for status + the original goal. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What this PR set out to do
framework/games/rpgbattle3d.js): a real 3D arena + a fixed ¾ camera, two skinned KayKit Knight instances (hero blue / enemy red, CC0), and a classic command-menu turn loop (HP/MP, Attack/Power Strike/Defend/Potion, crits, floating damage numbers). Works on web and PSP.OP_SET_BLENDwire op; web + PSP + 3DS const + contract) and an additive billboard that plays a CC0 explosion (StumpyStrust) on the struck fighter, with hit-stop + shake + screen-flash. Verified gorgeous in WebGL.✅ Done & verified
bun run testgreen (golden +.dc3ddraw-list + cross-host wire/button contract).⛔ Known issue (UNRESOLVED — why this is paused)
The hit VFX renders as a white box on PSP (it's perfect on web). The additive billboard goes through the PSP native render path (
renderNative→postOP stream), and that path isn't applying the texture + additive blend to a dynamic rigid quad — it draws a bare white quad.Fixes attempted (committed):
buildFlatonly registers dynamic nodes once, while the VFX node started hidden → never drawn. Fixed by keeping it registered and hiding viascale=0. Now the node draws on PSP (progress).post-stream rigid textured+additive OP_DRAW path needs deeper work (texture sampler + blend state for that specific draw path, which was built for skinned characters, not rigid sprites).postOP_DRAW for a rigid textured mesh: confirmOP_BIND_TEXTURE/apply_textureactually enablesTexture2Dfor it, and thatOP_SET_BLEND(sceGuBlendFunc Add/Fix) takes effect — likely the textured rigid path inruntime/src/gfx3d.rs(vs. the staticsceneAddpath which does texture correctly).post.🤖 Generated with Claude Code
