So who''s entering?

(i m btw)

I might work an an entry sunday , if i complete some sort of an entry i''ll post it . Unfortunately i haven''t got time till then .

I thought I would compile it and see what it was like, then decide if I wanted to make an entry. I can''t get it to compile in MSVC .NET, gives 13 build errors. I got the glut lib and header from http://www.xmission.com/~nate/glut.html and I belive I put those files in the correct places. I''m not really savvy enough to find the reason for the problems very quickly. If you want I will post the errors.

Post them anyway, it might be an easy solution to it.

Hmm, the last error can be solved by changing line 15 of glut.h from:

# if 0 

to

# if 1 

This means glut gets it''s definition of exit from windows.h, instead of redefining it''s own exit function.

The rest of the errors seem to be stemming from the templated casting member function in class Null. This is taken straight from Scott Meyer''s book ''Effective C++'', so I can''t imagine that the code is invalid. I''ll try compiling it under Visual C++ later today and see if I can get it to compile.

It''s interesting that Visual C++ spits out a couple of warnings - both Borland C++Builder and gcc compile it with out warnings, and I thought they were stricter than Visual C++!

Can you post a vc++ 6.0 workspace with your files...makes things a bit easier (vc++ 6.0 seems 2 b standard on this site).

ssnhavok: I tried compiling the code under VC++ .NET and I didn't get the errors you posted (I got a few other errors, but they were easily fixed). Try making the Null casting function inline, i.e. change:

template <typename TYPE>operator TYPE*() const;  

to

template <typename TYPE>operator TYPE*() const{	return 0;}  

in the class declaration and remove:

template <typename TYPE>Null::operator TYPE*() const{	return 0;}  

from after the class declaration.

everyone: I've uploaded a version that compiles under VC++ .NET (including the project file). I don't have access to VC++ 6, so if the .NET project file doesn't work in VC++ 6 then I'm afraid you're on your own .

Realised I hadn't said what the controls are. Assuming people are able to compile the code, and that they haven't figured the controls out already:
The mouse moves the bat.
Space begins play.
Enter skips to the next level (since only the fifth level has all brick types in it).

I took 5 minutes while working to go through the code on vc++ 6.0. Got it down to 10 errors...not enough time to finish the rest. Here they are:

wondering if u know a quick fix. I''ll post the vc++ 6.0 source if u want.

Have you tried inlining the casting operator as I suggested to ssnhavok in my last post? If that doesn''t work then get a decent compiler (or just rip out the Null class and operators and replace them with the line ''const int null = 0;'')
