How to make a web browser Game

No other external tools or programs are required except Game Maker and a dll.
Firstly to connect to the internet and use the HTTP protocol in Game Maker. You can either use the readily made mplay_ functions avaliable, but there a bit slow. I recommend using 39dll (GMC topic) to handle all your winsock calls.
So basically download the dll and scripts for 39dll.
Once you have them heres the code to execute a HTTP protocol:

01	// HTTP(host, GET/POST,POST variables)

02	if !bufferexists(global.HTTP_buffer)

03	global.HTTP_buffer=createbuffer();

04	//if !tcpconnected(global.HTTP_sock)

05

{

06	global.HTTP_sock = tcpconnect(argument0, 80, 0);

07	if(!global.HTTP_sock)

08

{

09	show_message("Unable to connect to "+argument0);

10	return -1;

11

exit;

12

}

13

}

14	setformat(global.HTTP_sock, 1, chr(13) + chr(10));

15	newLine = chr(13) + chr(10);

16	clearbuffer(global.HTTP_buffer);

17	writechars(argument1+" HTTP/1.0" + newLine,global.HTTP_buffer);

18	writechars("Host: "+argument0 + newLine,global.HTTP_buffer);

19	writechars("User-Agent: Shadow Zone/1.0" + newLine,global.HTTP_buffer);

20	if is_string(argument2)

21

{

22	writechars("Content-Type: application/x-www-form-urlencoded"+newLine,global.HTTP_buffer);

23	writechars("Content-Length: "+string(string_length(argument2))+newLine,global.HTTP_buffer);

24	writechars(newLine+argument2,global.HTTP_buffer);

25

}

26	//show_message(argument1+" HTTP/1.0" + newLine+"Host: "+argument0 + newLine+newLine+argument2);

27	sendmessage(global.HTTP_sock,"",0,global.HTTP_buffer);

28	processHeader = true;

29	while(processHeader)

30

{

31	receivemessage(global.HTTP_sock,0,global.HTTP_buffer);

32	firstWord = readsep(newLine,global.HTTP_buffer);

33	switch(firstWord)

34

{

35	case "": //blank line

36	processHeader = false;

37

break;

38

39	//read important stuff from header...

40

}

41

}

42	clearbuffer(global.HTTP_buffer);

43	setformat(global.HTTP_sock, 2);

44	retVal = "";

45

while(1)

46

{

47	size = receivemessage(global.HTTP_sock, 6000,global.HTTP_buffer);

48	if(size > 0)

49	retVal += readchars(size,global.HTTP_buffer);

50	else break;

51

}

52	return retVal;

This is how you would use the above code once 39dll and the scripts are implemented into your game.
To open www.nilbd.tk/index.php:

1	dllinit(0,1,1);

2	HTTP("www.nilbd.tk","GET /index.php");

This function will return the HTML code of the webpage. I’m not sure how you would parse the HTML code to display it as a webpage but that is how you access a webpage.
