TurtleTransit

Arrival timers for the zeppelins at the Orgrimmar towers, plus the Sparkwater Port boat, for the vanilla 1.12.1 client (tested on OctoWow / Turtle WoW).

A small minimap icon opens a window listing every transport with a live timer: how long until it leaves if it is docked, or how long until it docks if it is away. Click a transport to put a bell on it and get a chat message shortly before it arrives.

TurtleTransit is a standalone addon. It does not need pfUI or any other addon.

What you see Window element Meaning Green check Transport is docked now. The timer counts down to departure ("leaves"). Red X Transport is away. The timer counts down to docking ("docks"). ~ before a time An estimate from stored data. It goes away once you see the transport dock or leave. Bell on a row Alerts are on for that route (click a row to toggle). Footer Calibration state, e.g. baseline established: 3m (last seen 2h ago). It turns orange when the data is over 5 days old, as a hint to walk past the towers.

Routes tracked (with built-in starting values, which refine themselves as you play): Undercity, Grom'gol, Kargath, Thunder Bluff, and the Sparkwater Port boat (hide it with /tt boat). You can rename any route with /tt name.

Requirements ZepSense.dll, a small client DLL that exposes one Lua function, ZepTransports(), which returns the position of every zeppelin/boat the client currently has loaded. The addon cannot see transports without it. Without the DLL it shows built-in estimates only (marked ~). A client setup that loads DLLs listed in dlls.txt. Install Copy the TurtleTransit folder to Interface\AddOns. Copy ZepSense.dll to the game folder (next to WoW.exe). Add a line ZepSense.dll to dlls.txt in the game folder. Start the game fully (a /reload is not enough the first time the DLL is added). Type /tt debug. It should say the DLL function is present and show raw transport data when transports are in range.

The DLL only reads transport positions that the client has already loaded; it does not send anything anywhere. Source is ZepSense_v5.c (built with i686-w64-mingw32-gcc -O2 -shared -static-libgcc -Wl,--kill-at -s). As with any client DLL, use it at your own risk and check your server's rules.

Saved data lives in WTF...\SavedVariables\TurtleTransitDB.lua.

Using it Minimap icon: click to show/hide the window anywhere; drag to move it around the minimap edge. Auto-show: the window opens by itself in Orgrimmar and Durotar and hides elsewhere. The icon toggle always works manually. Add more auto-show places with /tt allow (use /tt where to see the exact names), or turn the behaviour off with /tt zone. Bells: click a transport row to toggle a bell. Belled routes print a chat message /tt alert seconds (default 45) before arrival. Nothing is printed to chat for routes without a bell. Move the window: drag it; /tt lock locks it in place; /tt resetpos puts the window and icon back. How the timing works

Each route runs on a fixed cycle. Once the addon sees one transport arrive, it can predict every later arrival, even while the transport is out of view (transports are only sent to your client when they are near you, so they drop out of range for part of each trip).

Automatic calibration: any arrival you watch near the towers calibrates that route. The first time takes two sightings, later refreshes take one. The cycle length is refined as more arrivals are seen, and the dock-time (how long a transport waits) is learned too. /tt calibrate (optional): watches every transport on purpose. Stand between the two towers where you can see the docks, do not /reload, and wait; rows are marked complete as each route is confirmed. A transport being out of view for a while is normal. If nothing at all has been seen after about 10 minutes, move closer to the towers. /tt calibrate stop cancels. Transports are not reported from deep inside the city (bank / auction house area), so calibrate near the towers. Commands

/tt (also /transit and /zep)

Command What it does /tt Show / hide the window (works anywhere) /tt list Print all timers in chat /tt alert Bell alerts fire this many seconds before arrival (default 45, 0 = off) /tt chat, /tt sound, /tt flash Toggle that alert type (chat on by default; sound and screen flash off) /tt zone Toggle "auto-show only in Orgrimmar / Durotar" /tt allow Also auto-show in this zone or sub-zone /tt allowclear Remove the extra auto-show places /tt where Print your zone / sub-zone and whether the window auto-shows here /tt boat Show / hide the Sparkwater Port boat /tt shape square|round|auto Minimap icon placement. auto reads your minimap shape (tell it explicitly if you use a square minimap addon and the icon sits wrong) /tt lock Lock / unlock the window position /tt resetpos Put the window and icon back in their default spots /tt name Rename route number n (numbers from /tt list) /tt period Set a route's cycle length by hand /tt calibrate Watch all transports on purpose (see above); /tt calibrate stop cancels /tt reset Forget everything learned and go back to built-in values /tt debug Show whether the DLL is answering and the raw data it returns Troubleshooting "no DLL: estimates only": the DLL is not loaded. Check that ZepSense.dll is in the game folder and listed in dlls.txt, then fully restart the game. /tt debug shows the state. Times have a ~ and never confirm: walk toward the towers and wait for an arrival, or run /tt calibrate. /tt does nothing or prints a start-up error: the addon reports its own load errors in chat; copy the message when reporting a bug. Window did not auto-show: use /tt where to see your zone and sub-zone names, then /tt allow if you want it there. Everything looks off after a big server change (new route timings): /tt reset, then calibrate again.
