# emberline.art.magkite The drawing kit MAG and KITE are made with, and the shared motion library (`emberline.art.magkite.motion`) that supplies the thirty-three clips every fighter in this game performs the same way. ## What is in here - **An index-buffer rasteriser.** `Ink.buffer(w, h, palette)` gives a plain Luau array of palette indices with `px / rect / blob / limb / poly / line / ribbon / speck / burst` on it, plus the finishing passes — `volume` (per-run shading, so an arm crossing a coat gets its own rounding), `grit` (deterministic wear that does not crawl between frames) and `outline`. A finished frame goes into the canvas in one call: `handle:addFrame(cells)`. - **A 2D skeleton.** `Ink.solve(pose, style)` turns a flat table of joint angles into sheet-space joint positions, with squash and stretch anchored at the ground line. `Ink.body` draws it back to front, taking the costume from the style's hooks (`behind`, `armBack`, `torsoOver`, `face`, `armFront`, `front`). - **Cloth.** `Ink.chain` / `Ink.flow` / `Ink.settle` wrap `pixelkit.follow` so a coat tail, a scarf and a lantern chain lead into a movement a frame late and keep travelling after the body has stopped. - **Clip assembly.** `Ink.clip` (key poses through `pixelkit.tween`), `Ink.cycleClip` (a loop that WRAPS, for the idle and the walks) and `Ink.buildSheet`, which writes every clip into a canvas and returns the clip index keyed by `Rules.CLIPS`. - **`Ink.auditSheet`** draws the whole sheet into a padded buffer and reports which clips put ink outside the 96x120 cell. A raster primitive clamps silently, so a pose that over-reaches loses pixels rather than failing; this is how those are found. ## Angles Degrees, positive turning toward screen-right, which is the way every sheet in this game faces. `aSh*` is an upper arm from straight down, `aEl*` is the FOREARM's own angle measured the same way (not a flexion — you pose an arm by deciding where the fist points), `lHip*` is a thigh from straight down, and `lKn*` IS relative, because a knee is a hinge that bends one way. ## Reach The cell is 96 wide and a fighter stands on its centre line, so a fully extended limb lands within a few pixels of the edge. Any pose that throws a leg out front pulls the root back with `x` to buy the room.
