Architecture Decision: Where Does the Manager Live?

ScopePolicyScript
Per character / enemy / turretScene-scoped manager as child (default)ability_manager.gd or composition ability_container.gd on the entity
Shared unlock / loadout catalog across scenesAutoload catalog / progression only (ranks, unlock flags) — not live cast stateThin Autoload data; casts still go through the entity manager
Global "cast any ability anywhere" AutoloadAvoidBreaks encapsulation and multiplayer authority

Resolved policy: Live cooldowns, GCD, and execute() run on a scene-scoped AbilityManager / AbilityContainer under the caster. Autoloads may store unlock ranks; they must not be the combat cast oracle. Skill-tree UI reads/writes progression data, then calls into the caster’s manager — never /root/AbilityManager.use_* for combat.

NEVER Do

  • NEVER tick cooldowns / status durations in _process() — Use _physics_process(delta) or one-shot Timers so cooldowns stay deterministic under frame spikes.
  • NEVER forget global cooldown (GCD) when design needs anti-spam — Small shared lock (0.5–1.5s) between casts when required.
  • NEVER hardcode ability effects in the manager — Strategy: each ability is a Resource / node with execute() (ability_resource.gd).
  • NEVER allow casts during animation lock — Gate on is_casting / anim signals.
  • NEVER save remaining cooldown floats without time normalization — Persist absolute end timestamps (Time.get_unix_time_from_system() + remaining).
  • NEVER put live combat cast state in a global Autoload — Scene-scoped manager (see decision table). Progression Autoloads are fine.
  • NEVER blindly ban or blindly require object pools — GDScript refcounting makes pool-optional for light VFX; do pool when spawn/despawn of projectiles/AoE is high-frequency or allocation shows up in the profiler. Prefer instantiate/queue_free until measured otherwise.
  • NEVER grow deep ability inheritance trees — Compose Resources + containers (godot-composition).

Golden Path (MANDATORY)

  1. ability_resource.gd — data + virtual execute()
  2. ability_manager.gd or ability_container.gd — scene-scoped cast/cooldown
  3. buff_stat.gd — when buffs/modifiers exist
  4. Damage resolution → godot-combat-system

Do NOT paste inline AbilityManager / ComboSystem / SkillTreeManager novels into scenes. Skill trees are progression UI + prerequisite graphs that grant Resources to the caster’s container.

Available Scripts

Cooldown & Status Timing Contract

  • Cooldown registry updates and status process_tick must use physics-frame delta (_physics_process) or Timer nodes owned by the container.
  • Hit detection from abilities stays on the physics tick when applying impulses / queries.
  • UI may read cooldown progress in _process; it must not own the truth.

Expert Techniques (short)

  • Dependency injection: parents inject caster context; abilities do not get_node("/root/Player").
  • Duck-typed hits: has_method(&"take_damage") / combat DamageData — see combat skill.
  • AoE: call_group or space queries; do not scan the whole tree each cast.
  • Networking: predict locally, authority validates can_use + costs (godot-multiplayer-networking).
  • Skill-tree visualizer: @tool GraphEdit for design-time graphs; runtime still grants Resources to scene managers.

Status Effects & Combos (critical WHY)

CAUTION: Status/buff templates applied at runtime must use duplicate(true). One poisoned .tres mutates every character sharing that asset — see status_effect_manager.gd.

  • Combos: combo_tracker.gd — sequence window + recipe table; finishers remain normal AbilityResource entries.
  • Charges: charge_ability.gd — recharge ticks belong on _physics_process, not UI _process.
  • Skill trees: skill_tree_manager.gd grants abilities to the caster's scene manager — progression Autoloads hold ranks only.
  • Save cooldowns: persist absolute end timestamps (Time.get_unix_time_from_system() + remaining), not raw remaining floats — prevents clock/load exploits.

MANDATORY for combos/charges/skill-tree/status/network depth beyond bullets above: elite-ability-patterns.md. Do NOT Load for a first AbilityResource + AbilityManager pass.

Reference

Progressive disclosure: Skim Official Documentation only for the APIs you are implementing (Resources, timers, signals, save, multiplayer). Open Related Skills when wiring adjacent systems—do not preload the whole lattice.

Official Documentation

  • Resources — Ability definitions, buffs, and status effects should be Resource data (not hardcoded manager switches) so designers can author and share assets.
  • Resource — Use duplicate(true) when applying a status/buff template at runtime so one character’s ticking state cannot mutate the shared .tres for everyone.
  • GDScript exports — @export / @export_group power Inspector-tuned costs, cooldowns, prerequisites, and effect arrays on ability Resources.
  • Using signals — Emit ability_cast, ability_ready, and cooldown lifecycle signals so UI and VFX subscribe without coupling to AbilityManager internals.
  • Scene organization — Keep “signals up, calls down”: parents/UI listen; managers call into ability Resources/nodes rather than reaching globally for combat state.
  • Idle and Physics Processing — Tick cooldowns and GCD in _physics_process (fixed delta); avoid _process for cooldown math that desyncs under frame spikes.
  • Timer — One-shot Timer children are a clean composition pattern for per-ability cooldowns in container-style managers.
  • SceneTreeTimer — create_timer() / await patterns fit cast times and short buff durations without adding persistent Timer nodes for every cast.
  • Groups — AoE abilities should call_group (or query groups) instead of hand-rolled scene scans for every hit target.
  • Time — Persist cooldown end timestamps (get_unix_time_from_system() + remaining), not raw remaining floats, across save/load.
  • Saving games — Serialize ability unlock ranks and absolute cooldown end times with the rest of player progression data.
  • High-level multiplayer — Authoritative cast validation + @rpc confirmation/cancel is the engine baseline for predicted ability casts.
Prerequisites
  • godot-resource-data-patterns — Abilities, buffs, and skill-tree nodes are Resource-first; load this before inventing custom serialization or inheritance trees for ability data.
  • godot-signal-architecture — Cast/ready/cooldown signals and UI hooks depend on disciplined signal ownership so AbilityManager stays decoupled from characters and HUD.
  • godot-composition — Prefer AbilityContainer / component nodes over deep BaseAbility → MagicAbility → FireAbility inheritance for runtime behavior.
  • godot-gdscript-mastery — Virtual execute() / can_cast(), typed Resources, and await-on-timer cast flows assume solid GDScript patterns.
Complements
  • godot-combat-system — Damage, hit reactions, and targeting pipelines consume ability execute() results; keep DamageData separate from ability metadata.
  • godot-rpg-stats — Mana/stamina costs, stat bonuses from skill ranks, and buff multipliers need a consistent stats/modifier layer.
  • godot-input-handling — Hotbar / action-map input should call can_use / use_ability rather than embedding cooldown logic in input callbacks.
  • godot-animation-player — Animation lock and cast telegraphs gate ability spam; wire AnimationPlayer start/finish into is_casting.
  • godot-state-machine-advanced — Cast, channel, and interrupt states belong in a character state machine that asks the ability manager, not the other way around.

## Architecture Decision: Where Does the Manager Live?

| Scope | Policy | Script |
|-------|--------|--------|
| Per character / enemy / turret | **Scene-scoped manager as child** (default) | [ability_manager.gd](scripts/ability_manager.gd) or composition [ability_container.gd](scripts/ability_container.gd) on the entity |
| Shared unlock / loadout catalog across scenes | Autoload **catalog / progression only** (ranks, unlock flags) — not live cast state | Thin Autoload data; casts still go through the entity manager |
| Global "cast any ability anywhere" Autoload | **Avoid** | Breaks encapsulation and multiplayer authority |

**Resolved policy:** Live cooldowns, GCD, and `execute()` run on a **scene-scoped** AbilityManager / AbilityContainer under the caster. Autoloads may store unlock ranks; they must not be the combat cast oracle. Skill-tree UI reads/writes progression data, then calls into the caster’s manager — never `/root/AbilityManager.use_*` for combat.

## NEVER Do

- **NEVER tick cooldowns / status durations in `_process()`** — Use `_physics_process(delta)` or one-shot Timers so cooldowns stay deterministic under frame spikes.
- **NEVER forget global cooldown (GCD)** when design needs anti-spam — Small shared lock (0.5–1.5s) between casts when required.
- **NEVER hardcode ability effects in the manager** — Strategy: each ability is a Resource / node with `execute()` ([ability_resource.gd](scripts/ability_resource.gd)).
- **NEVER allow casts during animation lock** — Gate on `is_casting` / anim signals.
- **NEVER save remaining cooldown floats without time normalization** — Persist absolute end timestamps (`Time.get_unix_time_from_system() + remaining`).
- **NEVER put live combat cast state in a global Autoload** — Scene-scoped manager (see decision table). Progression Autoloads are fine.
- **NEVER blindly ban or blindly require object pools** — GDScript refcounting makes pool-optional for light VFX; **do** pool when spawn/despawn of projectiles/AoE is high-frequency or allocation shows up in the profiler. Prefer instantiate/`queue_free` until measured otherwise.
- **NEVER grow deep ability inheritance trees** — Compose Resources + containers ([godot-composition](https://github.com/thedivergentai/gd-agentic-skills/blob/main/skills/godot-composition/SKILL.md)).

---

## Golden Path (MANDATORY)

1. [ability_resource.gd](scripts/ability_resource.gd) — data + virtual `execute()`
2. [ability_manager.gd](scripts/ability_manager.gd) **or** [ability_container.gd](scripts/ability_container.gd) — scene-scoped cast/cooldown
3. [buff_stat.gd](scripts/buff_stat.gd) — when buffs/modifiers exist
4. Damage resolution → [godot-combat-system](https://github.com/thedivergentai/gd-agentic-skills/blob/main/skills/godot-combat-system/SKILL.md)

**Do NOT** paste inline AbilityManager / ComboSystem / SkillTreeManager novels into scenes. Skill trees are progression UI + prerequisite graphs that grant Resources to the caster’s container.

## Available Scripts

- [ability_resource.gd](scripts/ability_resource.gd) — **MANDATORY** before new abilities
- [ability_manager.gd](scripts/ability_manager.gd) — **MANDATORY** Resource-driven cooldown registry (scene-scoped)
- [ability_container.gd](scripts/ability_container.gd) — **MANDATORY** alternative: node/Timer composition per ability
- [buff_stat.gd](scripts/buff_stat.gd) — modular buff stats (Do NOT Load if no buffs)
- [combo_tracker.gd](scripts/combo_tracker.gd) — windowed combo chains → finisher abilities
- [charge_ability.gd](scripts/charge_ability.gd) — multi-charge recharge (Flash-style)
- [skill_node.gd](scripts/skill_node.gd) / [skill_tree_manager.gd](scripts/skill_tree_manager.gd) — prerequisite graphs + point spend (progression only)
- [status_effect.gd](scripts/status_effect.gd) / [status_effect_manager.gd](scripts/status_effect_manager.gd) — ticking DoTs/buffs (`duplicate(true)` required)
- [ability_caster_network.gd](scripts/ability_caster_network.gd) — predict locally, authority validates RPC shell

## Cooldown & Status Timing Contract

- Cooldown registry updates and status `process_tick` must use **physics-frame** delta (`_physics_process`) or `Timer` nodes owned by the container.
- Hit detection from abilities stays on the physics tick when applying impulses / queries.
- UI may read cooldown progress in `_process`; it must not own the truth.

## Expert Techniques (short)

- **Dependency injection:** parents inject caster context; abilities do not `get_node("/root/Player")`.
- **Duck-typed hits:** `has_method(&"take_damage")` / combat DamageData — see combat skill.
- **AoE:** `call_group` or space queries; do not scan the whole tree each cast.
- **Networking:** predict locally, authority validates `can_use` + costs ([godot-multiplayer-networking](https://github.com/thedivergentai/gd-agentic-skills/blob/main/skills/godot-multiplayer-networking/SKILL.md)).
- **Skill-tree visualizer:** `@tool` GraphEdit for design-time graphs; runtime still grants Resources to scene managers.

## Status Effects & Combos (critical WHY)

> **CAUTION:** Status/buff templates applied at runtime **must** use `duplicate(true)`. One poisoned `.tres` mutates every character sharing that asset — see [status_effect_manager.gd](scripts/status_effect_manager.gd).

- **Combos:** [combo_tracker.gd](scripts/combo_tracker.gd) — sequence window + recipe table; finishers remain normal `AbilityResource` entries.
- **Charges:** [charge_ability.gd](scripts/charge_ability.gd) — recharge ticks belong on `_physics_process`, not UI `_process`.
- **Skill trees:** [skill_tree_manager.gd](scripts/skill_tree_manager.gd) grants abilities to the **caster's** scene manager — progression Autoloads hold ranks only.
- **Save cooldowns:** persist **absolute end timestamps** (`Time.get_unix_time_from_system() + remaining`), not raw remaining floats — prevents clock/load exploits.

> **MANDATORY** for combos/charges/skill-tree/status/network depth beyond bullets above: [elite-ability-patterns.md](references/elite-ability-patterns.md). **Do NOT Load** for a first AbilityResource + AbilityManager pass.
