Help Please!~

I have a new application made in BCB. I write the code,

Code:

---

//---------------------------------------------------------------------------

#ifndef Unit1H
#define Unit1H
//---------------------------------------------------------------------------
#include <Classes.hpp>
#include <Controls.hpp>
#include <StdCtrls.hpp>
#include <Forms.hpp>
#include <ExtCtrls.hpp>
//---------------------------------------------------------------------------
class TForm1 : public TForm
{
__published:        // IDE-managed Components
        TTimer *Down;
        TTimer *Up;
        TTimer *Left;
        TTimer *Right;
  TTimer *Down;
        TTimer *Up;
        TTimer *Left;
        TTimer *Right;
        void __fastcall UpTimer(TObject *Sender);
        void __fastcall LeftTimer(TObject *Sender);
        void __fastcall RightTimer(TObject *Sender);
        void __fastcall DownTimer(TObject *Sender);
        void __fastcall FormCreate(TObject *Sender);
       
private:        // User declarations
public:                // User declarations
        __fastcall TForm1(TComponent* Owner);
        void __fastcall TForm1::FormKeyDown(TObject *Sender, WORD &Key,
        TShiftState Shift);



        TCanvas *workCanvas;
        TRect        *BackRect;
        TImage *backgroundImage;
};
//---------------------------------------------------------------------------
extern PACKAGE TForm1 *Form1;
//---------------------------------------------------------------------------
#endif

---

but it throws linker errors:

Code:

---

[C++] Phantom_Fixed.cpp(1):
[C++] Unit1.cpp(1):
[C++] Loaded cached pre-compiled headers
[Linker]
[Linker Error] Unresolved external '_Enemy' referenced from M:\FINAL PROJECT\PHAMTOM FIXED\UNIT1.OBJ

Does anyone know how to fix this? thx

>>Unresolved external '_Enemy'
This means your source is calling a function that the linker cannot find. Are you linking all the necessary modules when you're compiling?

i think so... all that stuff is in a header file, which are included.
