Feature - Enable multi node flying for bots
- Bots currently only do node to node flying. This PR makes it so they
can connect multiple noted.
-- This is enabled by sending a vector containing the node sequence
instead of a single destination node
-- To minimize the run-time cost of searching for available nodes and
connection, a cache of all possible connections is prepared at start up
using a BFS search algorithm.
Refactor
- Move all world destination logic (cities, banks, inns) to existing
Travel manager
- Eliminate flightmastercache and integrate to new manager
- replace SQLs calls with in-memory data search by core
- Add in new map that stores creature areas by template.
Clean up
- Move other rpg files to related folder.
(Next steps) The selection for where bots fly to should be smarter than
it is. Instead of trying to determine where a bot can go, it should
first decide where it should go, and then identify the correct way to
get there.

## Feature Evaluation
Please answer the following:
- Describe the **minimum logic** required to achieve the intended
behavior?
- Describe the **cheapest implementation** that produces an acceptable
result?
- Describe the **runtime cost** when this logic executes across many
bots?

configuration)
- Expected behavior and how to verify it
## Complexity & Impact
Does this change add new decision branches?
- - [x[ No

The call itself is fairly infrequent, and although now there are a
greater number of paths available for the bots, I dont think it would be
significant.
## Defaults & Configuration
Does this change modify default bot behavior?

this change?
- - [ ] No
- - [x] Yes (**explain below**)
Gemini first suggested the use of a BFS algorithm. This was rewritten by
me to actually work as intended. Verification by additional logging not
present in final code.
Claude code converted the SQL filtering to the atrocious if statements
found in PrepareDestinationCache, but after verifying them it works. If
there are better ways to do this Im open to it.

Summary
This PR improves Follow related behaviour when the master is on a
transport (zeppelin/boat). It makes follow actions safer and less
disruptive by:
Detecting when the master is on a transport and handling boarding
correctly
Avoiding teleport-under-floor issues by using a small positional offset
when teleporting the bot near the master
Preventing movement conflicts between MoveSpline/MotionMaster and the
transport driver by forcing a MotionMaster cleanup and MoveIdle after
boarding
Clearing movement flags (forward / walking) after boarding so the bot
does not remain in a walking/march state
Next-check delay after boarding to allow the server to update
transport/position state
Before this change, bots get stuck when attempting to board
Fight the server-side transport movement because local
MoveSpline/MotionMaster was still active
Repeatedly attempt movement on every follow tick while already a
passenger, causing jitter and CPU/noise This PR reduces stuck/jitter
cases, avoids conflicting movement commands, and makes boarding more
robust.
**Key changes**
Check master->GetTransport() and handle three main cases:
If bot already passenger of same transport: stabilize (StopMoving,
Clear(true), MoveIdle, StopMovingOnCurrentPos) and set a longer
next-check delay; return false (no new movement in theory).
If bot passenger of another transport: do nothing (avoid conflicting
behaviour).
If bot not a passenger of master transport: teleport bot near master
(with offsets) and call Transport::AddPassenger(bot, true),
then force:
bot->StopMoving()
bot->GetMotionMaster()->Clear(true)
bot->GetMotionMaster()->MoveIdle()
Remove movement flags MOVEMENTFLAG_FORWARD and MOVEMENTFLAG_WALKING
SetNextCheckDelay to random 1000–2500 ms
Log boarding with bot name, transport GUID and coordinates
Preserve earlier follow logic when master is not on a transport
Tests performed
Manual tests on a local server:
Master on boat/zeppelin -> bot teleports to a safe offset position and
becomes a passenger without getting stuck
Bot already passenger on same transport -> bot no longer issues movement
commands and stabilizes
Bot on a different transport -> no boarding attempt for master's
transport (no interference)
Movement flags cleared after boarding; bot stops local movement and does
not fight server transport movement
Now the bots follow their masters in the zeppelins and boats, although
sometimes they move around a bit inside when the zeppelin starts (they
must have smoked something bad).

## Design Philosophy
We prioritize **stability, performance, and predictability** over
behavioral realism.
Complex player-mimicking logic is intentionally limited due to its
negative impact on scalability, maintainability, and
long-term robustness.
Excessive processing overhead can lead to server hiccups, increased CPU
usage, and degraded performance for all
participants. Because every action and
decision tree is executed **per bot and per trigger**, even small
increases in logic complexity can scale poorly and
negatively affect both players and
world (random) bots. Bots are not expected to behave perfectly, and
perfect simulation of human decision-making is not a
project goal. Increased behavioral
realism often introduces disproportionate cost, reduced predictability,
and significantly higher maintenance overhead.
Every additional branch of logic increases long-term responsibility. All
decision paths must be tested, validated, and
maintained continuously as the system evolves.
If advanced or AI-intensive behavior is introduced, the **default
configuration must remain the lightweight decision
model**. More complex behavior should only be
available as an **explicit opt-in option**, clearly documented as having
a measurable performance cost.
Principles:
- **Stability before intelligence**
A stable system is always preferred over a smarter one.
- **Performance is a shared resource**
Any increase in bot cost affects all players and all bots.
- **Simple logic scales better than smart logic**
Predictable behavior under load is more valuable than perfect decisions.
- **Complexity must justify itself**
If a feature cannot clearly explain its cost, it should not exist.
- **Defaults must be cheap**
Expensive behavior must always be optional and clearly communicated.
- **Bots should look reasonable, not perfect**
The goal is believable behavior, not human simulation.
Before submitting, confirm that this change aligns with those
principles.

# Pull Request
This change replaces the non‑standard
WorldPosition::getX/getY/getZ/getO/getMapId wrappers with the core
getters (GetPositionX/Y/Z, GetOrientation, GetMapId) and removes the
redundant wrappers.
Goal: align the module with AzerothCore conventions, reduce local
adapters, and improve long‑term maintainability.
---
## Design Philosophy
This is a structural cleanup only (coordinate access) and does not alter
any AI behavior or decision logic.
It follows the stability/performance-first philosophy and does not add
branches or extra runtime work.
Before submitting: yes, this change aligns with the principles of
stability, performance, and predictability.
Principles:
- **Stability before intelligence**
A stable system is always preferred over a smarter one.
- **Performance is a shared resource**
Any increase in bot cost affects all players and all bots.
- **Simple logic scales better than smart logic**
Predictable behavior under load is more valuable than perfect decisions.
- **Complexity must justify itself**
If a feature cannot clearly explain its cost, it should not exist.
- **Defaults must be cheap**

- **Bots should look reasonable, not perfect**
The goal is believable behavior, not human simulation.
Before submitting, confirm that this change aligns with those
principles.

## Feature Evaluation
Please answer the following:
- Minimum logic required: use core getters (GetPositionX/Y/Z, GetMapId,
GetOrientation) wherever coordinates are needed.
- Cheapest implementation: direct call replacement and removal of
redundant wrappers.
- Runtime cost: negligible (same data access, no additional logic).
---
## How to Test the Changes
- No functional testing required (behavior‑neutral refactor).
- Recommended: compile the module and run a normal server startup as
validation.

std::move was being used in a few places to return a vector. Its not
necessary. A direct return allows for some optimizations that moving
wouldnt.
