How to handle changes while zoning?

[Robske]

Heya

Most of my projects either crash during or need to be restarted after zoning. So my question is pretty straight forward.

Can I monitor 'zoning' out-of-process?

Hai Rob

The way I implemented this in my program, so it didn't matter what order the program and wow were started in is as follows:

Start a background thread with an loop than continuously checks whether
a) Process exists
b) can read from process
c) can read values (eg. is logged in) .

And if it can't it puts the main thread on hold, until it can read values again.

There is probably a better way, but this works, and it's simple.

Thanks for explaining, It sounds like a bandaidfix though, there must be something prettier

I know that it's probably possible to hook WoW's events (I assume the loadscreen is one of them) but I'm to much of a tool atm to do such a thing (C++ is planned for next month)

I'm hoping that there's a static address somewhere that could tell me what 'state' wow is in atm.

That would still crash if WoW closed :P

But I agree, it's not pretty.

Pseudo-code:

Try
     Read memory and stuff
Catch e As Error
     While Error.Exists
          Sleep(1000)
     End While
End Try

Not sure if this is what Gamer meant, but this is what I use.

Check pointers for null, early and always.

From memory there's a global variable that has the logged-in state.

Read the zone var, if zone != -1, you're in game, otherwise:

#define GAMESTATE 0x0103E6E8

That will tell you what screen you're at.

You can also hook EVENT_PLAYER_ENTERING_WORLD from BroadcastEvent at 0x0077F5D0.

WoWX uses this method and then you can add a check if event == EVENT_PLAYER_ENTERING_WORLD { load shizz in game } and same with other events.

Check into WoWX if you want more info!
