The reel's first-person mode now shows the fight, not just the rooms. The board flourishes' event map is recast into world space (fx3d): fireballs, bolts, and thrown things streak caster to target as glowing billboards; landings swell and fade; blows that land on YOU wash the screen red and jolt the camera; warp-steps and teleports flash violet; a hurled body glides fast and straight with its eyes held steady. Nine paintable conjuration sprites ship at public/fx3d (spec for the artist in research/), shown in the token workshop beside the masonry. Three rough edges sharpened along the way: sprites now project through warp mouths under the same rigid motion the rays use, clipped by the depth buffer to the opening; fire and warp surfaces pull a different texture slice per world cell so a long blaze reads as one; and the replay camera only turns toward an actor its eyes could actually see. Two more gifts: the reel can record its first-person canvas straight to a downloadable WebM (⏺ save video), and the About tab now shows visitors the way into the three workshops. One buried mine defused: rAF hands frame-start times that can precede the tween's own clock, and a zero-length turn divided by it — one NaN facing poisoned every ray black and re-triggered the camera effect forever. The tween clamps and guards its phases now. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# The conjuration sprites — a spec for the artist
|
||
|
||
The first-person view (`/?fpv`, and the replay's "your eyes" mode) throws
|
||
spell moments through the air as **billboard sprites**: flat images that
|
||
always face the camera, drawn glowing in mid-air, occluded by walls, and
|
||
scaled by distance. Nine sprites cover every spell moment in the game.
|
||
Each lives at `packages/web/public/textures/../fx3d/<name>.png` — replace
|
||
the file, refresh, done. The current files are placeholder radial glows;
|
||
all nine are shown side by side at `/?tokens` under "The conjurations."
|
||
|
||
## Technical requirements
|
||
|
||
- **Format:** PNG with a transparent background. The transparent area is
|
||
essential — whatever is opaque is what flies.
|
||
- **Size:** square, any resolution; 128×128 or 256×256 recommended. The
|
||
renderer scales freely and pixelates on magnification (the whole view
|
||
is deliberately chunky, like the wall textures).
|
||
- **Drawn additively:** sprites are composited in "lighter" (additive)
|
||
mode over a dark dungeon, so dark pixels vanish and bright pixels glow.
|
||
Paint light-on-transparent; pure black will be invisible. Midtones read
|
||
as translucent light.
|
||
- **No animation frames.** Each sprite is a single still. Motion comes
|
||
from the renderer: projectiles streak across the room, impacts swell
|
||
from small to large while fading out. Radially symmetric (or nearly so)
|
||
designs work best since the image does not rotate.
|
||
- **Fills most of the canvas.** Leave only a small transparent margin;
|
||
the renderer sizes the sprite by its canvas, not its painted extent.
|
||
|
||
## The nine sprites and where they appear
|
||
|
||
| file | flies as | moment |
|
||
| --- | --- | --- |
|
||
| `fireball.png` | projectile | Fireball, Sudden Death, Blaster Wand — a ball of fire streaking caster → target |
|
||
| `bolt.png` | projectile | Lightning Blast, Power Drain — a crackling bolt |
|
||
| `waterbolt.png` | projectile | Waterbolt — a hurled gout of water |
|
||
| `spark.png` | projectile | anything else that travels: thrown objects, bodies knocked back, dragged things — a neutral streak of force |
|
||
| `burst.png` | impact | a fireball landing; victory fireworks — swells and fades |
|
||
| `splash.png` | impact | waterbolt landing, stone turned to water |
|
||
| `hit.png` | impact | damage landing on someone you can see; punches, claws |
|
||
| `shimmer.png` | impact | teleports, warps, illusions, minds touched — the general "magic happened here" glimmer, violet by tradition |
|
||
| `shield.png` | impact | an attack fully stopped; absorbed spells |
|
||
|
||
Projectiles hold their size in flight (about a third of a wizard's
|
||
height). Impacts start small and swell to roughly double while fading —
|
||
so an impact painted as a ring or burst reads especially well.
|
||
|
||
What the sprites do NOT need to carry: screen-wide flashes when YOU are
|
||
hit (red), healed (green), or teleported (violet), and the camera shake —
|
||
those are renderer effects, not images.
