Here's a how-to for dev-cpp (windows), if anyone's interested:

1. If you don't already have GLUT then download GLUT for Mingw32 from this page. Follow the readme.txt in the glutming.zip download to add relevant headers, libs and glut32.dll to their respective directories.
2. Open up dev-cpp and create a new console, c++ or windows c++ project
3. Add Perspective's source files to your project (project menu--> Add to project). No modifications to those files are required.
4. Now add the libs: project menu --> project options, select 'parameters' tab. Add the following to the 'linker' field:
   Code:

   -lglut32 
   -lopengl32 
   -lglu32

5. A couple of options need to be passed to the compiler; the first is mandatory the second may not be (it isn't if you build from the command line). Open the 'projects' dialog (if you have closed it) to the 'parameters' tab as described for 'libs' above and add the following to the 'C++ Compiler' field:
   Code:

   -DGLUT_DISABLE_ATEXIT_HACK
   -D_WCHAR_T_DEFINED

6. Compile the project

If you built as a console project you'll get a console and a window; the console displays some information about game progress.

Comment - I hate GLUT.

A score would be nice but it's very playable all the same. Good stuff.

edit: Made some corrections - it's ok to build as a windows project and not just as a console as I originally had.

I think he means keeping score, so you can compare how much you 0wnz0r vs other people on the board.

Just for your info, VS.NET 2002 complained about only const static integral data members is allowed to be initialized inside a class or struct. It is easily fixed though (if anybody else has this problem):

Code:

// Change this in Item.h
class Item : public GraphicObject {

 protected:
  int points;
  int lifeTime;
  int creationTime;
  const static float len = 1.0f / (2*(WIDTH+5)); // 1/2 length of drawable width/height

 public:
	 Item() { init(); }
  Item(Point2i p) { setPos(p.x, p.y); init(); }
  Item(int x, int y) { setPos(x, y); init(); }
 ~Item() {}

  void init() { points = 0; }
  void setPoints(int p) { points = p; }
  int getPoint() { return points; }

  virtual void draw();
};

// to

class Item : public GraphicObject {

 protected:
  int points;
  int lifeTime;
  int creationTime;
  const float len; // 1/2 length of drawable width/height

 public:
	 Item():len(1.0f / (2*(WIDTH+5))) { init(); }
  Item(Point2i p):len(1.0f / (2*(WIDTH+5))) { setPos(p.x, p.y); init(); }
  Item(int x, int y):len(1.0f / (2*(WIDTH+5))) { setPos(x, y); init(); }
  ~Item() {}

  void init() { points = 0; }
  void setPoints(int p) { points = p; }
  int getPoint() { return points; }

  virtual void draw();
};

And

Code:

// In file SnakeBit.h change
class SnakeBit : public GraphicObject {

  SnakeBit* next;
  const static float len = 1.0f / (2*WIDTH); // 1/2 length of drawable width/height

 public:
	SnakeBit() { next = NULL; }
    SnakeBit(const Point2i p) { setPos(p.x, p.y); next = NULL; }
    SnakeBit(int x, int y) { setPos(x, y); next = NULL; }
    ~SnakeBit() {}

    SnakeBit* getNext() { return next; }


    void setNext(SnakeBit* n) { next = n; }

    void moveVertical(int amount) { pos.y += amount; }
    void moveHorizontal(int amount) { pos.x += amount; }

    virtual void draw();
};

// to
class SnakeBit : public GraphicObject {

  SnakeBit* next;
  const float len; // 1/2 length of drawable width/height

 public:
	SnakeBit():len(1.0f / (2*WIDTH)) { next = NULL; }
    SnakeBit(const Point2i p):len(1.0f / (2*WIDTH)) { setPos(p.x, p.y); next = NULL; }
    SnakeBit(int x, int y):len(1.0f / (2*WIDTH)) { setPos(x, y); next = NULL; }
    ~SnakeBit() {}

    SnakeBit* getNext() { return next; }


    void setNext(SnakeBit* n) { next = n; }

    void moveVertical(int amount) { pos.y += amount; }
    void moveHorizontal(int amount) { pos.x += amount; }

    virtual void draw();
};

This was the only way I could get the game running (if I copied it correctly ) but otherwise it is nice!
