Pointer problem

[Peter Müller]

Hi there.
I've two classes. One has the member IrrlichtDevice *device.
How can the other class use this poiner?

I tried to give the second class this pointer in a parameter, but my compiler said, "Syntaxerror: 'IrrlichtDevice'" in every cpp File, which included the header of the second class

help me, please

well, hard to tell you a solution, seems to be a c++ syntax problem. Either you post some code here or your compiler with its error message. Maybe you forget the namespace? irr::?

I've got the feeling, it's a precompiler error:

Code: Select all

#include <stdio.h>
#include <Irrlicht.h>
using namespace irr;
using namespace video;



class CHeightMap
{
 protected:
  SHeightMapSize hmsSize;
  CHeightPoint hpHeight[16];

 public:

  CHeightMap(void);
  CHeightMap(FILE *HeightMapFile);
  ~CHeightMap(void);

  bool init(FILE *HeightMapFile);
  SHeightMapSize    getSize(void);
  void              setSize(SHeightMapSize hmsSize);
  CHeightPoint      getHeight(int iIndex);
  CHeightPoint      getHeight(int iX, int iZ);
  void              drawAll(int iX, int iZ, IrrlichtDevice &device);
  //void              drawAll(IVideoDriver *driver);

};

You're right, I forgot the namespace, but this wasn't the problem.

well, post the compiler error message the, why you give a reference of the irrlicht device try to give a pointer.

[Peter Müller]

OK, I got it!

Code: Select all

void              drawAll(int iX, int iZ, IrrlichtDevice &device); 

is wrong

Code: Select all

void              drawAll(int iX, int iZ, IrrlichtDevice *device); 

is right


@schick:
I didn't post the compiler errors, because they're on german and i didn't know exactly how to translate.

instead of passing it as a variable.. you can make the variable (if it's defined in the class and not a method) a "friend" variable.. if you set the second class to be a "friend" class. but sending it as a param wont hurt. just for future refference.

Thanks, you're right!
