Hi,
I have a game in c++ using GLUT.
Now i want that game to run on Web browser.
Do i need to write the whole game again or few modifications will do the job?

try to inject your c code into flash

actually its a chess game.so u mean i need to build the game again in flash to be able to play on web browser.
since i have no experience writing flash games,is it possible to write chess game in flash or do i need to code in some other language?

there must be a command in flash to use c commands directly or call compiled .exe or you can use command line functions in your c program to open browser. try
----------
gwbasic 10 CLS
qbasic A$=INKEY$
fortran printf("hello word");
labview |_|--->|_|-|-|_|----->o
c if(A=='q') {
cobol MOVE "hello world" TO A
c++ }
algol END
pascal .
