// Facing (direction) rules of the prep board — pure logic, no DOM (research 09 §1.2, DESIGN §3 "Facing (corrected)").
|
||||
//
|
||||
// Every board piece has a direction `dir ∈ UP|RIGHT|DOWN|LEFT`, chosen with the standard Arknights 4-direction deploy
|
||||
// wheel after a legal drop on a board tile (also the piece's own tile: re-orienting in place). Range grids are
|
||||
// `[dRow, dCol]` offsets relative to facing RIGHT (row 0 = the bottom row, nearest the camera) and rotate as
|
||||
// RIGHT (dr, dc) · UP (dc, −dr) · LEFT (−dr, −dc) · DOWN (−dc, dr).
|
||||
// Screen space of the wheel: +x right, +y down; the camera looks "up" the board, so screen-up = towards higher rows =
|
||||
// UP. A swipe shorter than the dead-zone (~0.5 tile) chooses nothing (release there = cancel). On the mirrored right
|
||||
// half of the Final Assault prep a screen direction maps to its board direction through `boardDir(dir, mirror)`.
|
||||
//
|
||||
// Also here: which drops enter the direction step, which range grid previews, and the underframe (selection diamond)
|
||||
// actions of a tapped piece — 撤退 / 出售 +N on a board operator, 撤退 on a board summon, 出售 +N on a bench operator,
|
||||
// 销毁 on items and Arts (research 09 §5 / §6.5).
