Deriving from t2dStaticSprite?

by James Ford · in Torque Game Builder · 03/11/2008 (9:44 pm) · 1 replies

I am attempting to make a new class derived from t2dStaticSprite and am getting the following error:
Quote:3>structure.obj : error LNK2001: unresolved external symbol "bool __cdecl VectorResize(unsigned int *,unsigned int *,void * *,unsigned int,unsigned int,char const *,unsigned int)" (?VectorResize@@YA_NPAI0PAPAXIIPBDI@Z)

I'm really at a loss here... Anyone willing scan through my code will be reimbursed in abundant positive karma.

Here is my .h file:
#ifndef _STRUCTURE_H_
#define _STRUCTURE_H_

#ifndef _T2DSTATICSPRITE_H_
#include "T2D/t2dStaticSprite.h"
#endif


class Structure : public t2dStaticSprite
{
   typedef t2dStaticSprite Parent;
   
public:

   Structure();
   ~Structure();

   DECLARE_CONOBJECT(Structure);

   static void initPersistFields();

//protected:
   
   virtual bool onAdd();
   virtual void onRemove();
};

#endif // _STRUCTURE_H_

And my .cpp file:

#include "console/consoleTypes.h"
#include "structure.h"


Structure::Structure()
{
   // nothing to do
}

Structure::~Structure()
{
   // nothing to do
}

IMPLEMENT_CONOBJECT(Structure);

void Structure::initPersistFields()
{
   Parent::initPersistFields();
   
   //addField( "actingUnit", TypeSimObjectPtr, Offset( mActingUnit, Action ), "" );   
}

bool Structure::onAdd()
{
   if(! Parent::onAdd())
      return false;

   return true;
}

void Structure::onRemove()
{
   Parent::onRemove();
}

Hmm this is strange. I just looked though the TGB code and VectorResize is defined in source/core/tVector.h and implemented in source/core/tVector.cc.

The only thing that I can think of that would cause this linking error for you is that tVector.cc was removed from your solution; however, I would also imagine if that was the case then you would be getting a lot more linking errors than just that one.

Have your tried cleaning the solution and doing a full new build? (I'm sure you have) .. you could have an old dependency messing things up.

It certainly doesnt look like its anything in your code that I can see; however, on saying that I havn't played around with the engine code much or extended it - so I'm not sure if you've missed an important line of initialization / registration code out.
