Tower Defense Power Grid (relays, light beam, night)
/mechanic-tower-defense-power-grid
A GameSkill original: towers fire only while linked to the power source through relays, a fixed capacity is shared in a stable order so new towers never black out old ones, selling recomputes and reports a brownout, a movable light beam adds damage and slow, and at night towers need light to see far.

自检清单
- 卖掉中继后，下游的塔立刻停火，并提示断电 / Selling a relay stops the towers behind it at once and shows a brownout
- 新建的塔不会让已有的塔断电 / Building a new tower never switches off an existing one
- 塔不会把电转发给别的塔 / Towers never pass power on
- 光束的增伤和减速用同一个范围判断 / The beam's damage bonus and slow use the same in-spot test
- 夜里画面上看不见的敌人，塔也打不到 / At night, enemies you cannot see are enemies no tower can shoot
- npm test 和 npm run test:browser 都通过 / npm test and npm run test:browser pass
中文指南
这个 skill 做什么
GameSkill 原创（MIT）。在普通的塔防上加一层电网：塔必须经过中继连到电源才能开火，电源容量有限，按“优先级 → 建造先后 → 跳数”稳定分配，所以新塔永远不会让老塔断电；卖掉中继会重算下游并提示断电。另有一束可以移动的光：光斑里伤害 +25%、速度 −15%；夜里塔只能看到射程 70% 以内的敌人，更远的必须被光束、灯塔或有电的中继照亮。
什么时候用
- 在做塔防，想加电力、能量、电塔、中继
- 想做夜战、照明、探照灯玩法
- 塔会因为造了别的东西而莫名其妙地开开关关
怎么装
下载本页的 ZIP，把 mechanic-tower-defense-power-grid/ 文件夹放进 .claude/skills/（Claude Code）或 .agents/skills/（Codex、Cursor），重启 agent。没有运行时依赖。
最小示例
示例《港口灯塔》：16×9 棋盘，灯塔就是电源。node test/serve.mjs 后打开 http://localhost:8770/；先点工具再点棋盘，选 Beam 后拖动光束，N 切换昼夜。加 ?demo 看脚本演示：入夜、卖掉中继造成断电、再建回来。
我们怎么测的
npm test 跑 14 个 Node 测试：连线范围、中继串联、塔不转发、容量截断和置顶、建造先后优先于距离、卖中继和卖塔的重算、光束限速、增伤和减速、夜间视野和灯光，还有两场完整战斗：同一波怪在有中继时零漏怪、没中继时大量漏怪；夜里开光束守住、不开守不住。npm run test:browser 在无头 Chrome 里用触屏点击做 11 项检查，包括建造、出售、断电提示、光束移动、夜间可见性和没有控制台错误。
致谢
设计思路来自 stackloomdev 的 Last Beacon（MIT）：灯塔经中继供电、容量有限、可操控的光束、取决于光照的夜间视野。我们沿用了 +25% 伤害、−15% 速度、70% 视野这三个数值，代码、布局和文字都是我们写的。

- Harbor Lamp: a 16x9 Canvas 2D board with a lighthouse, relays, three tower types, tap and keyboard controls
- src/logic.js: link ranges, BFS from the source, stable capacity allocation, recompute with lost and gained lists
- A light beam that moves at a capped speed and gives +25% damage and 15% slow inside its spot
- Night sight: 70% of tower range unless the enemy is lit by the beam, the source or a powered relay
- 14 Node tests (including whole-wave fights) and an 11-check headless Chrome test
适合
- Tower defense games with power, energy, pylons or relays
- Night waves, lighting and spotlight mechanics
- Fixing towers that switch on and off when unrelated things are built
不适合
- Paths, wave design and targeting modes on their own (see tower-defense)
- Electrical simulation with voltage, losses or flow

Add a power grid to my tower defense: towers need to be connected to the generator through pylons, power is limited, and selling a pylon should cut the towers behind it.关于这个 Skill
A GameSkill original, written and tested for gameskill.dev under MIT. The demo, Harbor Lamp: a lighthouse powers towers through relays on a 16×9 board, with a steerable beam for night waves. All rules are in src/logic.js (no DOM).
Agent steps
- Nodes, not towers: one list;
connected,hops,poweredare rewritten only byrecompute(grid). - Recompute on every change and return
lost/gainedfor a brownout pop-up. - Towers never relay; only the source and relays transmit.
- Stable allocation: priority, then build order, then hops. A new tower never blacks out an old one.
- Show the cause: live and dead cables, link-range rings, ⚡! (over capacity) vs ⚡✕ (no link).
- Beam as a moving spot with a capped speed; damage bonus and slow use the same
inBeamtest. - Night sight in one function shared by targeting and rendering; powered relays are lamps too.
- Prove it with fights: the same wave with and without the relay, at night with and without the beam.
Common errors it fixes
- Towers flickering because allocation depends on distance or array order.
- Towers still firing after their relay was sold.
- Night rules that hide enemies on screen but not from targeting.

环境要求
- Any engine: the rules are plain JavaScript and port line by line
- Node.js 20+ to run the tests; Chrome for the browser check

Kart Drift Boost (tiers, windows, ramps)
A GameSkill original: arcade kart drift-boost rules that reward skill. Drifts charge three tiers, release opens a 0.85 s window you must press in, counter-steer adds a CUT bonus, ramps give one air and one landing boost, boosts take the maximum instead of stacking, and walls cancel everything pending.
One-button Flight (fair tap-to-flap)
A GameSkill original: the rules of a one-button flight game that is never unfair. Flaps set speed instead of adding it, a fixed-step simulation plays the same at 30 and 144 fps, the hitbox forgives grazes, and a seeded gap generator stays inside the reachable band, checked by an autopilot.
Procedural Low-Poly Buildings (kit, validator, views)
A GameSkill original: build stylised low-poly buildings in code from a small spec, then prove them: plot and height limits, a triangle budget per tier, closed outward meshes, supported parts, level roofs and side-only taper measured from silhouettes, plus front, side, top and 3/4 renders checked against the geometry.
