UCGO SDK Question "EatCloserCargoByType"

[Buzz313th]

Can this function be used with a negative argument to actually load resources into a cargo?

Mhhh usually I always but safety on parameters, you might try but I doubt it work.

Ok, can I ask you one more question please.

And I am appologising ahead of time for my ignorance in C++ as I just started learning it a week ago with no code
experience prior.

Can you tell me whats wrong with this code.  I can't get it to check the argument in the if statement.  I have a feeling
I am not stating the "none" parameter correctly.

         // After cueing action area "0" connect/disconnect battery
         char *CargoGrappled = hUcgo.GetCargoDescriptionString(0);
         if (CargoGrappled == "none")
         {
            sprintf (oapiDebugString(), "none");
         }
         else
         sprintf (oapiDebugString(), CargoGrappled);

you cannot compare two string with "==" you should use string comparison function like strcmp (string compare) strstr (string
search)  highlight one function and hit F1 for help.

Also I urge you to name your variable in a correct way, always the type first (f=float d=double i=int etc) then a
comprehensive name.

Exemple:

Code: [Select]

int iNbrOfCrewAboard;
double dAltitudeAboveGround;
float fO2TankLevel;

When you reach 2-5'000 lines of code incorrect variable name is a major reason of project crashing because the code become
unreadable.


In your case char * is a character pointer so:

Code: [Select]

// After cueing action area "0" connect/disconnect battery
char *cPtrCargoDescription = hUcgo.GetCargoDescriptionString(0);
if (strcmp(cPtrCargoDescription ,"none")==0)
{
        strcpy(oapiDebugString(), "none");
}
else
{
     strcpy(oapiDebugString(), cPtrCargoDescription );
}

Hope this help ?

Holy smokes..  it worked.  Thanks.  

I can't believe how lost I am..   I know I will get this done, but after clawing and scratching at the code for a few
weeks...  

I hope you don't mind other questions sometime..

My pleasure is to pass my knowledge, I've made a few tutorials and API about C++ but unfortunately they are in french...
Maybe with a translater ?

Now I have a big pleasure to teach my knowledge when I feel it's usefull: the guy is gifted and have a great learning curve.
If it's not the case it's probably useless anyway.

(Picto one user have wrote on big vessel dll after a few questions and reading the tutorials)

Learning a language is not having a big memory, it's only knowing a few logical principes, a few functions (say 10-15 to be
able to read code /execute it in head) AND knowing WHERE to search the other informations.

I explain the "method" here:
http://orbiter.dansteph.com/forum/index.php?topic=6337.msg95356#msg95356
unfortunately it's in french and unfortunately again my english is too bad to rewrite it in english.


Knowing the big picture and how/where to search is the key. A good programmer is a good detective first.

Keep up the good work

Dan
