I just read the UMMU SDK for tips and help on how to implement it in my .dll. It was a relatively easy procedure involving copy/paste. I did everything the document said to, but with only partial success. I know even if it compiles that it still doesn't mean it will work properly. Better than nothing though. I am going to post the code I have (most of it) to see if you guys can spot an error. Another useful note is that when Orbiter starts I do not get no response from UMMU. I tried pressing A for airlock then E for the EVA, but that didn't work either.

Here is the code.

Code:
class Spacecraft: public VESSEL3 {
public:
    Spacecraft (OBJHANDLE hObj, int fmodel);
    void DefineAnimations (void);
    void clbkPostCreation (void);
    void clbkDrawHUD (int mode, const HUDPAINTSPEC *hps, HDC hDC);
    void clbkSaveState(FILEHANDLE scn);
    void clbkLoadStateEx (FILEHANDLE scn, void *status);
    
    // Overloaded callback functions
    void clbkSetClassCaps (FILEHANDLE cfg);
    void clbkPostStep (double simt, double simdt, double mjd);
    int  clbkConsumeBufferedKey (DWORD key, bool down, char *kstate);
    UINT anim_eng;
    int MySoundID;


    // UMMU 2.0 DECLARATION
    UMMUCREWMANAGMENT Crew;
    int SelectedUmmuMember;                // for the SDK demo, select the member to eva
    int iActionAreaDemoStep;            // this is just to show one feature of action area.

    // The HUD display method variable, see PDF doc
    char cUmmuHudDisplay[255];            // UMmu hud char variable
    double dHudMessageDelay;            // UMmu hud display delay
    char *SendHudMessage(void);            // UMmu hud display function

    // THIS IS FOR ADDING CREW SEE PDF doc "Allow user to add crew to your ship 
    // without scenery editor"
    char cAddUMmuToVessel[255];
    void AddUMmuToVessel(BOOL bStartAdding=FALSE);
};

Code:
void Spacecraft::clbkSaveState(FILEHANDLE scn)
{

    // ORBITER, default vessel parameters
    SaveDefaultState (scn);

    // UMmu, this will save all our members of crew in scenario

    // it's your responsabilites to save and reload UMmu's airlock state.

Sorry for how long the code is, but it is relevant. :shrug:

I've never dealt with UMMU, so can't offer any help directly, but for me it usually helps not to just mindlessly copy-paste, but to read through the code to see what it actually does and rewrite most of it myself if possible.

I have read through the code though. Dan has even said in the SDK that copying and pasting is probably the easiest thing and then trying to understand it. I just would like to know where I messed up at because i doesn't ev,en work in my addon.

Posting random snippets isn't that helpful, I get no context for where you're putting the code you're pasting in.

As RisingFury said, look at the sample code, follow it, trace it through and work out what does what, and what goes where and why. Copying code you barely understand into a project made of copied code you barely understand is just going to cause you problems. Perhaps you should get a C++ book.

Oh - and "spacecraft.dll" is a really bad name for your vessel module, just FYI.
