Problem Statement + +### 2.1 Critical Gaps in Execution Layer + +The three BattlegroundAI.cpp methods for TOK are stubs: + +**`PickupOrb()` (line 1579):** Only logs a debug message and returns true.

No target finding, following, or combat engagement. + +**`ExecuteKotmoguStrategy()` (line 1569):** Calls the two stubs sequentially with no role-based decision branching. + +### 2.2 Missing Execution Behaviors +- No orb GameObject interaction (finding nearby orbs, navigating to them, using them) +- No combat engagement — bots never call `Attack()` against enemy players +- No movement execution — bots don't move to strategic positions +- No escort behavior — bots don't follow or protect orb carriers +- No enemy orb carrier hunting — bots don't pursue enemy players holding orbs +- No center push execution — bots don't move orb carriers to the center zone + +### 2.3 Data Accuracy Issues +- Scoring model in `TempleOfKotmoguData.h` uses a simplified 2-tier system (3pts outside, 15pts center) but the actual TrinityCore server uses 3 concentric area triggers with different point values per 5 seconds: + - **Small area** (innermost/center): 6 pts per 5s (`Plus5VictoryPoints`) + - **Medium area** (middle ring): 4 pts per 5s (`Plus4VictoryPoints`) + - **Large area** (outer ring): 2 pts per 5s (`Plus3VictoryPoints`) +- This doesn't affect bot behavior significantly (center is still best), but the data constants should be accurate for the blueprint to be trustworthy. + +--- + +## 3. Requirements + +### 3.1 R1: Orb Pickup (Critical) + +**Description:** Bots assigned the ORB_CARRIER role must find, navigate to, and pick up available orbs. + +**Behavior:** +1.

When assigned NODE_ATTACKER or FLAG_HUNTER role: find enemy orb carriers and attack them +2. When assigned FLAG_ESCORT or NODE_DEFENDER role: attack enemies threatening friendly orb carriers +3. Combat sequence: `SetSelection(target)` then `Attack(target, true)` for melee, or cast spells for ranged +4. Target validation: target must be alive, hostile, and in range +5.

When `ShouldPushToCenter()` returns true, orb carriers navigate along pre-calculated routes from `GetOrbCarrierRoute()` +2. Escorts maintain formation around the carrier using `GetEscortFormation()` +3. Center detection uses `IsInCenterZone()` (within 25 yards of center point) +4.

Query BattlegroundCoordinator for bot's current role +2. Query TempleOfKotmoguScript for current strategy phase and decisions +3.

Bot should re-enter strategy after respawn. +2. **Orb respawn:** When an orb respawns, nearby bots without orbs should attempt pickup. +3. **Multiple bots targeting same orb:** Only one bot can pick up an orb. Others must re-target to different orbs. +4. **No orbs available:** All 4 orbs held. Bots without orbs should defend carriers or hunt enemy carriers. +5. **Team size imbalance:** Strategy should adapt if team has fewer players (more conservative). +6. **Null pointers:** All player/object lookups must be null-checked. + +**Success Criteria:** Zero crashes across all edge cases. Bots recover from unexpected states within one update cycle. + +### 3.6 R6: Logging & Observability (Medium) + +**Description:** Add detailed logging for debugging and validation during manual testing. + +**Log Categories:** +- Orb pickup: attempts, successes, failures with reason +- Combat engagement: target selection, attack initiation, target death +- Strategy transitions: phase changes, role reassignments +- Center push: decisions, movement, arrival +- Errors: null pointers, invalid states, unexpected conditions + +**Log Level:** `TC_LOG_DEBUG` for routine events, `TC_LOG_INFO` for state transitions, `TC_LOG_ERROR` for error conditions. + +**Logger:** `playerbots.bg.tok` for TOK-specific events, `playerbots.bg` for general BG events. + +**Success Criteria:** A tester can reconstruct a full game timeline from logs. + +--- + +## 4.

Reads bot's role from coordinator and delegates to role-specific behavior. + +**Logic**: +1. Get `BattlegroundCoordinator*` via `sBGCoordinatorMgr->GetCoordinatorForPlayer(player)` +2. If no coordinator, fall back to simple behavior (PickupOrb or patrol) +3. Get `IBGScript*` via `coordinator->GetScript()`, cast to `TempleOfKotmoguScript*` +4.

An ORB_CARRIER that already has an orb executes carrier movement (center push or hold); one without an orb executes pickup. + +#### 3.2.2 `PickupOrb()` (Replace stub at line 1579) + +**Purpose**: Find an available orb, navigate to it, and use the GameObject to pick it up. + +**Logic**: +1. Check if player already holds an orb (check auras 121175-121178). If yes, return true (already done). +2. Get coordinator and TOK script. If available, get prioritized orb list from `tokScript->GetOrbPriority(faction)`. +3. For each orb in priority order: + a. Check if orb is already held: `tokScript->IsOrbHeld(orbId)`. Skip if held. + b. Get orb position: `tokScript->GetDynamicOrbPosition(orbId)` (falls back to hardcoded positions). + c. Calculate distance to orb position. +4. Select the nearest unheld orb from the priority list. +5. If no orb available (all 4 held), return false. +6. If distance > `OBJECTIVE_RANGE` (10.0f): call `BotMovementUtil::MoveToPosition(player, orbPos)` and return true (in progress). +7. If within range: search nearby GameObjects using `player->GetGameObjectListWithEntryInGrid(goList, orbEntry, OBJECTIVE_RANGE)`. +8. For each found GO: verify `goInfo->type == GAMEOBJECT_TYPE_FLAGSTAND`, verify `go->IsWithinDistInMap(player, OBJECTIVE_RANGE)`, then call `go->Use(player)` and return true. +9. If no GO found in range despite being at position: log warning and return false (orb may have been picked up between checks). + +**Orb entry to check**: Use constants from `TempleOfKotmoguData.h`: +- `TokData::GameObjects::BLUE_ORB` (212091) +- `TokData::GameObjects::PURPLE_ORB` (212092) +- `TokData::GameObjects::GREEN_ORB` (212093) +- `TokData::GameObjects::ORANGE_ORB` (212094) + +**Orb auras to check** (for "already holding" detection): +- `TokData::Spells::ORANGE_ORB_AURA` (121175) +- `TokData::Spells::BLUE_ORB_AURA` (121176) +- `TokData::Spells::GREEN_ORB_AURA` (121177) +- `TokData::Spells::PURPLE_ORB_AURA` (121178) + +**Conflict resolution**: When multiple bots target the same orb, the first to call `go->Use(player)` wins. Others will find `IsOrbHeld()` returns true on next tick and re-target. + +**Template**: Follows `PickupFlag()` (line 650) and `CaptureBase()` (line 1151) patterns exactly. + +#### 3.2.3 `DefendOrbCarrier()` (Replace stub at line 1591) + +**Purpose**: Position near a friendly orb carrier and attack enemies that threaten them. + +**Logic**: +1. Get coordinator and TOK script. +2. Find a friendly orb carrier to defend: + a. Using coordinator: iterate `tokScript->GetOrbHolder(orbId)` for all 4 orbs. Filter for same-faction holders. + b. If multiple friendly carriers, choose the nearest one. + c. If none found, fall back to patrolling center area. +3. If friendly carrier found: + a. Check distance to carrier. If > 30.0f (DEFENSE_RADIUS): `BotMovementUtil::MoveToPosition()` toward carrier. + b. If within 30.0f: check for nearby enemies using `coordinator->QueryNearbyEnemies(carrierPos, 30.0f)`. + c. If enemies found near carrier: `player->SetSelection(enemy->GetGUID())` then `player->Attack(enemy, true)` for the nearest/most dangerous. + d. If no enemies: maintain escort distance (8.0f behind carrier using angle-based positioning, same as `EscortFlagCarrier`). +4. If no carrier found: patrol around center or nearest orb spawn using `BotMovementUtil::MoveRandomAround()`. + +**Template**: Follows `DefendFlagRoom()` (line 1006) and `EscortFlagCarrier()` (line 899) patterns. + +#### 3.2.4 `HuntEnemyOrbCarrier()` (NEW) + +**Purpose**: Find and attack enemy players who are carrying orbs. + +**Logic**: +1. Get coordinator and TOK script. +2. Find enemy orb carriers: + a. Iterate all 4 orbs via `tokScript->GetOrbHolder(orbId)`. + b. For each held orb, get the holder player via `ObjectAccessor::FindPlayer(guid)`. + c. Filter for enemy faction (not same team as bot). + d. Select nearest enemy carrier. +3. If enemy carrier found: + a. Check distance. If > combat range (30.0f): `BotMovementUtil::ChaseTarget(player, enemyCarrier, 5.0f)`. + b. If within combat range: `player->SetSelection(enemyCarrier->GetGUID())` then `player->Attack(enemyCarrier, true)`. +4. If no enemy carrier found: + a. Use spatial cache: `coordinator->GetNearestEnemy(playerPos, 40.0f)`. + b. If enemy found: attack them. + c. If no enemies: move to a strategic position (center or nearest contested orb spawn). + +**Template**: Follows `FindEnemyFlagCarrier()` (line 847) + `ExecuteFlagHunterBehavior()` patterns. + +**Priority targeting**: Enemy carriers in center zone (earning 6pts/tick) are higher priority than those outside. + +#### 3.2.5 `EscortOrbCarrier()` (NEW) + +**Purpose**: Follow and protect a friendly orb carrier as they move to center. + +**Logic**: +1. Get coordinator and TOK script. +2. Find nearest friendly orb carrier (same logic as DefendOrbCarrier step 2). +3. If carrier found: + a. Calculate escort position using trigonometric positioning (behind carrier at 8.0f distance). + b. Use `BotMovementUtil::MoveToPosition()` to escort position. + c. If enemies approach within 15.0f of carrier: engage them with `Attack()`. + d. If carrier is in combat: assist by attacking carrier's attacker. +4. If no carrier found: fall back to `DefendOrbCarrier()` behavior. + +**Template**: Follows `EscortFlagCarrier()` (line 899) pattern exactly. + +**Escort formation**: Uses `tokScript->GetEscortFormation(carrierX, carrierY, carrierZ)` which returns 8 positions (4 melee-range, 4 ranged) around the carrier. + +#### 3.2.6 `ExecuteOrbCarrierMovement()` (NEW) + +**Purpose**: Once a bot holds an orb, move toward center zone for maximum scoring. + +**Logic**: +1. Get coordinator and TOK script. +2. Check if center push is appropriate: `tokScript->ShouldPushToCenter(faction)`. + - Requires 2+ friendly orbs held and >= 30s elapsed. +3. If should push to center: + a. Get route from `tokScript->GetOrbCarrierRoute(orbId)` (4-5 waypoints to center). + b. Navigate along waypoints using `BotMovementUtil::MoveToPosition()`. + c. Once in center (within `CENTER_RADIUS` = 25.0f of center), hold position. + d. If in center and enemies approach: consider retreating if outnumbered (check `coordinator->CountEnemiesInRadius(centerPos, 30.0f)` vs allies). +4. If should NOT push to center: + a. Hold near orb spawn (defensive positioning). + b. Use `tokScript->GetOrbDefensePositions(orbId)` for defensive spots. + c. Stay alive — carrier dying loses the orb. +5. Survival priority: If health < 30% and outnumbered, move away from enemies. + +**Center position**: `TokData::CENTER_X` (1732.0f), `TokData::CENTER_Y` (1287.0f), `TokData::CENTER_Z` (13.0f). + +--- + +## 4.

Risk Mitigation + +### 7.1 Orb Pickup May Fail Silently + +**Risk**: `go->Use(player)` may not trigger pickup for bots (server-side validation might reject bot interactions). + +**Mitigation**: After calling `Use()`, verify on the next tick that the bot has the corresponding orb aura. If not, log failure reason and retry. The server-side code uses `GAMEOBJECT_TYPE_FLAGSTAND` which is the same type WSG flags use — and WSG flag pickup already works for bots via the same `Use()` API. + +### 7.2 Coordination Layer Returns Stale Data + +**Risk**: `IsOrbHeld()` may return stale data if the coordination layer hasn't processed the `ORB_PICKED_UP` event yet. + +**Mitigation**: Always check the actual aura on the target player as a secondary validation, not just the coordination layer's tracking. + +### 7.3 Multiple Bots Race for Same Orb + +**Risk**: Multiple bots converge on same orb, wasting time. + +**Mitigation**: Accept this as normal behavior. The first bot to `Use()` gets the orb. Others will re-evaluate on next tick (500ms interval) and target a different orb. The orb priority system (faction-based) already distributes bots across different orbs naturally. + +### 7.4 Movement Interruption During Combat + +**Risk**: `MoveToPosition()` could override combat movement. + +**Mitigation**: `BotMovementUtil::MoveToPosition()` already never interrupts `CHASE_MOTION_TYPE` (combat movement). This is built into the movement utility. Additionally, check `player->IsInCombat()` before issuing non-combat movement commands. + +### 7.5 TempleOfKotmoguScript Cast Failure + +**Risk**: `coordinator->GetScript()` returns non-TOK script or null. + +**Mitigation**: Always verify the script's `GetBGType() == BGType::TEMPLE_OF_KOTMOGU` before casting.
