I was told not to have global variables and given an example. Ifollowed it and now I get this error:only const static integral data members can be initialized inside a class or struct

Re: only const static integral data members can be initialized inside a class or struct

imsorryicantunderstandwhatyourquestionisbecauseitlookslikethis

Try rearranging your post without the LaTex tags

Although, with reference to the subject line - look at the private members in your class (Of which there are far, far too many... if i were you, the first thing i'd do would be to look at a way to cut them down.. such as an array)

You can't directly assign a value to a data member in the class, you need to initialise them in the class constructor instead.

Re: only const static integral data members can be initialized inside a class or stru

I fixed it. I was told not to have global variables. And send an example

Now I need to see hwta is going on with this:
C++ Syntax (Toggle Plain Text)
  1. // --------------------------------------------------------------
  2. // Vessel cleanup
  3. // --------------------------------------------------------------
  4. DLLCLBK void ovcExit (VESSEL *vessel)
  5. {
  6.     if (vessel) delete (Chariot*)vessel;
  7. }
  8. void Chariot::clbkPreStep (double simt, double simdt, double mjd)
  9. {
  10. sprintf(oapiDebugString(),"start %2.2f", start );   
  11.  
  12. if (0==start){
  13.  
  14.     SetThrusterGroupLevel (THGROUP_MAIN, 0);
  15.     SetThrusterGroupLevel (THGROUP_RETRO, 0);
  16.     SetThrusterGroupLevel  (THGROUP_ATT_YAWLEFT, 0);
  17.     SetThrusterGroupLevel (THGROUP_ATT_YAWRIGHT, 0);  
  18. }
  19. }
What happens is event though start =1 the sprintf shows it is 0 and the set thrusterlevel part doesn't work.
