Multiplayer Doom

[dazmanultra]

Could you imagine wireless multiplayer Doom? :blink:

It would seriously ROCK!

 

[Gpnat0r]

yeah!!! me and my brother have both one gp and 2 want play it!

 

[washo]

me too....But I heard that it would be impossible due to the lack of speed with the ext port...
see you

 

[Vimacs]

how fast is the wireless connector?
hmm wasent there a option to play doom over nullmodem?

 

[rcx21000]

how fast is the wireless connector?

I think that it is 14kbps or something... I dunno what doom needs, but I doubt that its over 24kbps... Or mabye someone could make a double RF mod, so you can get 28kbps (unless it is the max ext port speed limiting it...)

Duke nukem 3d only requires 9kbp per sec connection for modem play, I can't imagine Doom would need more.

 

[Vimacs]

i think gp32 has 2x uart @ 115200 one with handshaking but iam not sure
maybe we could solder a nullmodem cable for gp?

 

[washo]

I cant find it anymore but I remember craigx saying that would be ipossible
maybe someone should have a look around the forum
see you

Maybe a direct USB connection could work, never tried it but I heared you can do a PC network with USB too.

 

[Morwynd]

I don't think a USB link would be possible. The problem with USB is that it is client-server, not peer-to-peer (like Firewire for example).

GP32 is a USB client and needs to connect to something that acts like a USB server (like a PC), not another GP32 client.

But then again, who knows? GP32 is so programmable perhaps it can be made to act like a USB server device instead of a client.

The RF port runs at something like 128 bytes per second or less.

It can just about send over joypad movements for basic games.

For doom you would need some kind of cable connection.

If it's that slow, then why couldn't you just send key movements? Both GP's could calculate both of the player's positions/weapons/stuff... Just make each var a [1] array, and then in each of the function add an arg for weather it's for [0] or [1] then from the main loop you could do:

1. Get pressed keys
2. Send pressed keys
3. Wait to receive other keys
4. Do all calcs for your player
5. Do calcs for other player (not including drawing to screen)

And for the 2nd GP it would be:

1. Wait to receive keys
2. Get pressed keys
3. Send pressed keys
4. Do all calcs for your player
5. Do all calcs for other player (not including drawing to screen)


It would work for processor speed atleast, since the main loop with only one player to calc runs perfectly @ 40MhZ... so just set @80MhZ or more

i wouldn't mind using a direct link cable instead of wireless myself. who knows, maybe it's the next thing after people selling pre-modded chatboards. not that i know anyone in my country with a gp32 though (except ph0x, but he's a busy guy )
