// server/sim/content/devices.js — stage devices & special terrain (data/stages.json, research 05 §2.3–2.4).

//
|

// The engine already spawns active 阻隔工事 crates (obstacle devices, 100 HP) and marks active 射击台/mounds as
|
||||
// obstacles that elevate operators. This module adds, per battle:
|
||||
// 阻隔工事 an enemy blocked by a crate destroys it (after its attack interval even if it cannot attack: harmless
|
||||
// walkers no longer stall on a crate); map cards (`deviceOverrides`) remove crates / add or remove
|
||||
// platforms (obstacle + elevation) / activate hidden devices
|
||||
// 气流 act2 m01 blowers (`trap_013_blower`, rangeTiles along `dir`): operators whose direction (`u.dir`, UP|
|
||||
// RIGHT|DOWN|LEFT) equals the blower's dir / is its opposite / is perpendicular get ATK +
|
||||
// blower_s_character[equal|opposite|vertical].atk (the m01 blowers blow DOWN); enemies moving with /
|
||||
// against the flow get move speed × (1 + blower_s_enemy[equal|opposite].move_speed)
|
||||
// 沼泽 m +1 stack on entering and every intervalSec s on the tile (max maxStacks): ASPD aspdPerStack (fractions
|
||||
// are ×100 ASPD), move speed × (1 + moveMulPerStack × stacks); cleared on leaving (allies and ground enemies)
|
||||
// 烟雾 g operators on it cannot be targeted by enemy ranged attacks (stealth flag: blocked enemies still hit them)
|
||||
// 深水 d ground enemies on it: sea_drown[enemy].damage true dmg/s, ASPD attack_speed (×100), move × move_speed
|
||||
// 活性源石 i units on it (allies and ground enemies): damage true dmg/s, ATK + atk, ASPD + attack_speed, for
|
||||
// `duration` s of battle time
|
||||
// “双眼皮” turrets (`trap_1104_aclasert`, band 机械援助 / `deviceOverrides` alias on): ranged arts shooter on its data
|
||||
// range; ASPD + attack_speed_per_stack × L (≤ max_attack_speed), hits apply fragile 1 + damage_scale_per_stack
|
||||
// × L (≤ max_damage_scale) for the text's duration; L = the owner's highest bond layers (live)
|
||||
// 盟约寒风 `startColdWind` / `kjeragColdWind` helpers for the 谢拉格 bond (every interval s all enemies cold)
|

// Device overrides: a player's battle input `deviceOverrides` ({ alias: bool }) and `alias` keys in its playerEffects
|
