// render/tiles.js — stage renderer (DESIGN §9, research 07 §7).
|
||
//
|
||
// The ground (low tile tops, the island's cliff edges) is one PIXI.Mesh with a custom perspective-correct shader:
|
||
// every quad carries (u·w, v·w, w) texture coordinates with w = 1/depth, so the material atlas (render/textures.js:
|
||
// the real 卫戍协议 board art of the local client when installed — render/boardArt.js — else procedural) maps onto
|
||
// the trapezoid tiles without the affine "kink". Vertices are re-projected only when the camera changes. Draw
|
||
// order (painter's): backdrop ground plane → cliff faces → low tops. The island stands on a large textured ground
|
||
// plane (the board art's concrete backdrop) with baked contact shadows, fading into fog with distance.
|
||
//
|
||
// Raised blocks (high ground, forbidden blocks, walls, bench pads) are one mesh PER ROW placed in the depth-sorted
|
||
// unit layer (outer→inner within the row, each block's visible sides before its top), keyed at the row's far edge
|
||
// (`rowDepthKey`): a unit standing farther away than a block row is drawn before it, so the block hides its feet /
|
||
// lower body; units on or in front of the row are drawn after it. Things lying ON a raised top (highlights, unit
|
||
// shadows, facing chevrons, ground rings) go into that row's surface container (`surfaceLayer(row)`), drawn right
|
||
// after the row's blocks and devices but before its units.
|
||
//
|
||
// Also:
|
||
// * highlight groups (legal green / illegal red / attack range orange / custom) — Graphics, redrawn on change,
|
||
// * gate (red) and objective (blue) wireframe boxes with warning glyphs, pulsing (redrawn per frame),
|
||
// * animated terrain: smog puffs, deep-sea shimmer, infection glow, mire bubbles, teleport rings,
|
||
// * devices: crates, platforms, sealed floors, blowers (▶▶ plate + airflow along rangeTiles), turrets are textured
|
||
// boxes in their row's block mesh; mounds and bushes are Graphics in the depth-sorted unit layer. Battle
|
||
// devices (sim units) use `BoxMesh`, the same textured box as a standalone mesh.
|
||
// High-ground plates pick a frame piece by connectivity (horizontal strip L/M/R, vertical strip B/VM/T, single).
|
||
// Tiles outside the playable area fade out with distance, so the board reads as a lit island over the backdrop.
|
||
//
|
||
// External board (`setExternal(true)`): the official 3D board scene (render/board3d) draws the tiles, blocks, gates,
|
||
// devices and animated terrain on its own canvas under the Pixi one. The field then keeps only what lies on top
|
||
// of the board — highlight groups, blower airflow streaks — plus the grid queries (tile / heightAt / levels) that
|
||
// units, FX and hit-testing use, so both layers agree on every height. No meshes, Graphics props or anim sprites
|
||
// are built; switching back (WebGL context lost, art missing) rebuilds the 2D board.
