slicer

Cuts closed procedural meshes along planes and caps the cut, so the katana leaves clean pieces. Used by `CrewDirector` when a katana kills a fruit thug, and again when a lying piece is slashed.

What it does

game.enemies.slicer

Cuts closed procedural meshes along planes and caps the cut, so the katana leaves clean pieces. Used by CrewDirector when a katana kills a fruit thug, and again when a lying piece is slashed.

  • S.cut(parts, n, p) → neg, pos: split a solid (a list of { mat, geo } parts in one frame) by the plane through p with unit normal n. Crossed triangles are split with interpolated normals and UVs; the cut edges of all parts are welded by position and chained into loops, and every closed loop gets a cap on both pieces.
  • S.cutAll(parts, { {n, p}, ... }) → every piece after cutting by each plane.
  • S.bounds(parts) → centre, half extents, triangle count.
  • S.CUT maps a flesh material to the cut-face material that shows its cross-section (tomato → cut_tomato, ...). Loops through flesh cap with it, UV-mapped to the loop's bounds so the texture's round slice fills the section; other loops (eyes, buckles) cap in their own material 1.5 mm inward.

cap(pts: { { number } }, n: { number }, e1: { number }, e2: { number }, flesh: boolean, negGeo: Geo, posGeo: Geo) → void

Close one cut loop on both pieces. pts = loop points (each {x,y,z}), ordered so the negative piece's cap faces +n.

collect(list: { Part }) → void

Merge the parts of a piece that share a material.

cut(parts: { Part }, n: { number }, p0: { number }) → void

Split `parts` by the plane through p0 with unit normal n. Returns the negative piece (behind the plane) and the positive one; either may be empty.

the point where edge i-j crosses the plane: one position per welded edge (so every part and both pieces agree), attributes per chart

capMaterial(parts: { Part }, lp: any) → string

Which material closes a loop: the solid's flesh cut face for a flesh loop (the first flesh material in the solid), else the material of the part whose surface the loop's first point lies closest to.

Cut by several planes in turn ({ { n, p }, ... }); returns every piece.

# game.shared.geo Procedural geometry kit for Banana 2077. The world has no imported models, so every curved thing in the game (the banana hero and his baton, the fruit and vegetable gang, the gold peel megatowers) is built from these generators. - `G.lathe`, `G.tube`, `G.blob`, `G.grid` build MeshGeometry tables (flat arrays, 0-based CCW indices, normals, uvs). `opts.open` on `G.grid` builds an open sheet instead of a closed ring. - `G.xform`, `G.merge` move and combine them; `G.mesh` uploads a runtime mesh, `G.asset` writes a durable `.mesh` asset. - `G.q*` quaternion helpers ({x,y,z,w}): `qMul`, `qInv`, `qRot`, `qAxis`, `qFromTo`, `qBasis`, `qLook`, `qSlerp`. Called by `game.player.parts`, the enemy builders and the city district.

Usability ratings

Did the part work as advertised when consumers tried to drop it in. Separate from upvotes: those are taste; this is "did it function".
