Network multiplayer
As promised, DIV now has a working multiplayer.
| Code: |
program redwar;
global
struct j[2]
x,y,graph;
size,angle;
shot;
end
yo,myfont;
begin
load_fpg("steroid/steroid.fpg");
myfont=load_fnt("red.fnt");
set_mode(m640x480);
set_fps(35,4);
net.device=0; // TCP/IP
net.num_players=2;
net.max_players=2;
yo=net_join_game("MyGame",&j,sizeof(j));
if (yo<0) exit("Error...",yo); end
player(yo);
enemy(1-yo);
end
process player(i)
begin
x=640*i;
angle=i*pi;
y=240;
graph=1;
write(myfont,0,0,0,"Game ID:");
write_int(myfont,100,0,0,&net.com);
write_int(myfont,0,20,0,&net.server);
write_int(myfont,0,40,0,&yo);
loop
if (key(_right)) angle-=15000; end
if (key(_left)) angle+=15000; end
if (key(_up)) advance(8); end
if (key(_space))
shot(x,y,angle);
j[i].shot=1;
else
j[i].shot=0;
end
j[i].x=x;
j[i].y=y;
j[i].angle=angle;
j[i].size=size;
j[i].graph=graph;
frame;
end
end
process shot(x,y,angle)
begin
graph=2;
advance(24);
repeat
advance(16);
frame;
until (out_region(id,0));
end
process enemy(i)
begin
loop
x=j[i].x;
y=j[i].y;
graph=j[i].graph;
size=j[i].size;
angle=j[i].angle;
if (j[i].shot)
shot(x,y,angle);
j[i].shot=0;
end
frame;
end
end

As you can see the code is very simple. We keep a struct with the shared information, and update it with our player positions, then each frame it is
automatically updated and the opposing player (enemy) is drawn on screen at the correct positions, and even shoots bullets when required.
I'll try to do a better example this week, but look out for network support in a future beta and nightly build.

Impressive.
Is it possible to run the program and get the same result as shown in the screenshot as is? (i.e 2 game windows)
Will it run over 2 computers?
Sorry, I have no idea about networking.

Yes, here is a link to a youtube video where you can see it in action.

Also yes it will run on two computers. At sone point it will hopefully enable 100s of simultaneous players.

Hi Mike,
If you've got a minute or two, do you think you could give me a pointer or two regarding how to set this up? I've tried it on a single computer and
I just get a single window. I really don't have a clue.
Thanks.

The demo you see on youtube / screenshot is only in a development build with specific compile flags - and those changes havent made it into the most
recently nightly build yet anyway so you're a bit out of luck!
However, once it *is* in the build, you just open two instances of DIV, and run the program twice. The first game runs the server, and the second runs
the client. This is going to change though as div-arena will become the game server - and all games will be clients.
Hope that makes sense!
