Use for a tower-defense/wave-defense game, or balancing waves and economy.\n---\n\n# Tower Defense\n\nA playbook for tower defense — enemy pathing, wave spawning, tower targeting, and the\neconomy that ties them together. This is a **compositional** skill: it orchestrates pathing,\nAI, and UI into a TD loop. It does not re-teach pathfinding; it defines the systems and the\nbalance levers (DPS vs. HP vs. income) that decide whether a TD is tense or trivial.\n\n## When to use\n\n- Use when building a game where the player **places towers** that automatically attack\n  **waves of enemies** following a path, spends earned currency to expand/upgrade, and loses\n  if too many enemies leak through.\n- Use when designing wave composition/pacing, tower targeting priorities, or the gold economy.\n\n**When _not_ to use:** the player directly controls a shooter → `fps-shooter`. Free-form base\nbuilding with needs → `survival-crafting`. For the pathfinding algorithm itself, use `game-ai`.\n\n## Core loop\n\n**Prepare (place/upgrade towers with current gold) → start the wave → enemies path toward the\ngoal while towers auto-fire → earn gold from kills → survive the wave → repeat against a\nharder one.** The tension is a planning puzzle: is my current DPS enough for what's coming,\nand can I afford the answer?\n\n## Must-have systems\n\n1. **Enemy path** — waypoint lanes, or grid + pathfinding for maze TD (refs).\n2. **Wave spawner** — timed, scripted sequences of enemy types with per-wave scaling.\n3. **Towers** — range, fire rate, damage, projectile/hitscan, splash; placement validity.\n4. **Targeting** — per-tower priority (first/last/closest/strongest/weakest) (refs).\n5. **Economy** — gold from kills + wave bonuses; tower/upgrade costs; sell refund.\n6. **Lives / leak** — enemies reaching the goal cost lives; 0 = game over.\n7. **Wave/prep UI** — lives, gold, next-wave preview, start-next-wave control.\n\n## Design knobs\n\n| Knob                      | Effect                  | Notes                                    |\n| ------------------------- | ----------------------- | ---------------------------------------- |\n| Enemy HP growth/wave      | upgrade pressure        | Geometric ~1.1–1.2× (refs).              |\n| Income vs. HP curves      | difficulty              | Player should _almost_ afford each wave. |\n| Tower DPS / range / cost  | tower identity          | Cheap+wide vs. expensive+tall.           |\n| Targeting priority        | optimal placement       | Changes play more than raw stats.        |\n| Enemy variety             | counters one-build wins | Fast / armored / flying / swarm / boss.  |\n| Leak penalty              | stakes                  | Cost lives _and_ lost bounty.            |\n| Upgrade vs. build economy | strategy depth          | Diminishing upgrade returns.             |\n| Wave pacing               | tension curve           | Spike → breather → spike, not monotonic. |\n\n## Patterns\n\n### 1. Wave spawner (timed, data-driven)\n\n```python\n# Pseudocode. A wave is data: a list of (enemy_type, count, spacing). Spawn over time.\nwave = [ (\"grunt\", 10, 0.5), (\"runner\", 5, 0.3), (\"tank\", 2, 1.0) ]\n\ndef run_wave(wave):\n    for enemy_type, count, spacing in wave:\n        for _ in range(count):\n            spawn_enemy(enemy_type, at=path[0])   # enter at the path start\n            wait(spacing)                          # seconds between spawns (use a timer/coroutine)\n    # wave clears when all spawned enemies are dead or have leaked\n```\n\n### 2. Tower targeting (filter to range, then pick by priority)\n\n```python\n# Pseudocode. \"First\" (furthest along path) is the standard default for stopping leaks.\ndef acquire_target(tower, enemies, mode=\"first\"):\n    in_range = [e for e in enemies if distance(tower.pos, e.pos) <= tower.range]\n    if not in_range: return None\n    if mode == \"first\":    return max(in_range, key=lambda e: e.progress)   # furthest along path (stop leaks)\n    if mode == \"last\":     return min(in_range, key=lambda e: e.progress)   # least progress (guard the entrance)\n    if mode == \"closest\":  return min(in_range, key=lambda e: distance(tower.pos, e.pos))\n    if mode == \"strongest\":return max(in_range, key=lambda e: e.hp)         # burn down tanks first\n    if mode == \"weakest\":  return min(in_range, key=lambda e: e.hp)         # secure kills / last-hit bounty\n    return in_range[0]\n```\n\n### 3. \"Can this lane hold?\" sanity check (DPS vs. HP)\n\n```python\n# Pseudocode. One tower's damage to one enemy crossing its range.\ntower_dps     = tower.damage * tower.fire_rate\ntime_in_range = tower.range_coverage_length / enemy.speed\ndamage_dealt  = tower_dps * time_in_range\n# Lane holds if summed damage_dealt from covering towers >= enemy.hp (per enemy). See refs.\n```\n\n## Pitfalls / failure modes\n\n- **Enemy HP scales slower than player income/DPS** → game trivializes after a few waves.\n  Tune the HP curve against the income curve (refs).\n- **One dominant tower/strategy** → no decisions. Add enemy types that hard-counter builds\n  (armored vs. rapid-fire, flying vs. ground-only) and diminishing upgrade returns.\n- **Maze TD that can fully block the goal** → enemies get stuck/softlock. Forbid placements\n  that sever the path; recompute paths when towers change (refs).\n- **No next-wave telegraph** → specials feel random and unfair. Preview upcoming composition.\n- **Per-frame movement unscaled by `dt`** → speed varies with frame rate. Scale steering by `dt`.\n- **Leaks only cost lives, not gold** → leaking is sometimes optimal. Make leaks lose bounty too.\n- **Monotonic difficulty ramp** → exhausting. Pace spikes and breathers.\n\n## Composition (build it from these skills)\n\n- **Pathing:** `game-ai` for A\\*/flow-field/steering; for fixed lanes, simple waypoint following.\n- **Enemy movement:** `godot-2d-movement` (or engine equivalent) to move along the path; `unity-navmesh` for nav-based pathing.\n- **Map:** `godot-tilemap` / `unity-tilemap-2d` for the grid/lanes; `level-design` for map layouts.\n- **Data:** `godot-resources` / `unity-scriptableobjects` to define towers, enemies, and waves as assets.\n- **UI:** `game-ui-ux` for HUD layout, scaling, and the build menu; `godot-ui-control` for the concrete widgets (lives, gold, wave preview).\n- **Polish:** `audio-design` for fire/hit/leak sound cues.\n\n## References\n\n- For path representations (waypoints / A\\* / flow fields), targeting modes, DPS and economy\n  math, enemy scaling, and wave pacing, read `references/balancing.md`.\n","tagline":"Build a tower defense: enemies pathing along lanes, wave spawning, towers that auto-target and fire, an economy, and lives.
