For TAKP server, the boat routes use spawn conditions and are timed with grids. All synchronization has to be achieved via precise timing. Unfortunately, boats can't send send signals across zones. This is hard coded into the client.

If a grid is timed too short or too long, players will either get dropped off in the water or players will end up at the safe spot in the destination zone. Boat zones need to be static.

Server-Side Source

BoatID Constants

The following boats and their ID's are described as enum constants in the server source code: https://github.com/EQMacEmu/Server/blob/main/common/eq_constants.h#L685

//These are NPCIDs in the database. All of these boats send a BoardBoat opcode when boarded.
enum Boats
{
    Stormbreaker = 770, //freporte-oot-butcherblock
    SirensBane  = 771,
    Sea_King = 772, //erudext-erudsxing-qeynos
    Golden_Maiden  = 773,
    Maidens_Voyage  = 838, //timorous-firiona
    Bloated_Belly = 839, //timorous-overthere
    Barrel_Barge = 840, //Shuttle timorous-oasis
    Muckskimmer = 841,
    Sabrina = 24056, //Shuttle in Erud
    Island_Shuttle = 96075, //Shuttle to Elf docks in timorous
    Captains_Skiff = 842, //Shuttle timorous-butcherblock
    Icebreaker = 110083, //iceclad
    pirate_runners_skiff = 843 //Shuttle iceclad-nro
};

Zone Entry

Each time a client enters a zone, the server checks the client packet's player profile struct for a boatid > 0 and whether the client is currently in Timorous Deep or Firionia Vie. If this is true, the boatid in the player profile struct is set back to 0.

void Client::Handle_Connect_OP_ZoneEntry(const EQApplicationPacket *app)
...
	if(m_pp.boatid > 0 && (zone->GetZoneID() == timorous || zone->GetZoneID() == firiona))
		pps->boat[0] = 0;

https://github.com/EQMacEmu/Server/blob/main/zone/client_packet.cpp#L1644

Boat ID's are stored in the player profile packet (pp.boatname and pp.boatid).

When you board the boat, the boatid is registered in the PlayerProfile in the code (common/patches/mac_structs), sent by the client to the server, and temporarily stored in the `character_data`.boatid field in the database. So when the boat moves, we send the pc to their destination and the boatid. If the player finds that boatid in their destination zone, it will land on it. Otherwise, it will be sent to the zone safe location.

Boat Route Implementations

Implementing a boat is achieved via entries to the database and the LUA scripting engine. The original implementation on TAKP for most of the boats was done by Cavedude (BB to Tim Deep shuttles was the only route he didn't finish).

Database Settings

The following database tables are used:

spawn2
spawngroup
spawn_conditions
grid_entries
grid
npc_types.boatid

LUA Scripting

Events

event_spawn
event_waypoint_arrive
