Author Topic: Simple example of LAN game with 2-4 PCs? (Read 3831 times)

madscijr · « **on:** July 02, 2021, 04:21:03 pm »

Hi all,
I'm interested in writing a simple local network game for 2-4 PCs.
I have no idea how to approach it, and am not too knowledgable about networking, so would like to keep it as simple as possible while still following whatever the standard practices are. It should not require the users to know much about networking or mess with the networking/firewall settings on their computer (if possible?)
Can anyone either post some code or maybe a link to a simple & minimal example of a game for 2-4 computers (preferably connected together via a wired hub)?
Any info would be much appreciated...

PS If it makes any difference, this would be for lower bandwidth games, stuff like Battleship, Spacewar, Pong, Roguelikes - not any kind of super fast MMO 3D game sending/receiving a ton of data.

@FellippeHeitor Sounds like a job for Amongst

Hehe 🤩

https://github.com/FellippeHeitor/amongst <-- run the server once, up to 10 clients can connect

That looks really neat, I will give it a look. Thanks!

Can always check out my BattleShip game, it has LAN options.

Question, what format file is "battleship.gfx", and how would you edit it?
Thanks...

I was looking at your code, and got the genius idea (I hope you are picking up on the sarcasm here)
to rename the variables a little less ambiguously to help me follow what the code is doing,
and I seem to have introduced a little bug where when you place a ship on the board, it disappears.
If you have any bandwidth, and could quickly zero in on the line that might be making that happen,
that would be very much appreciated... No pressure or anything, LoL

Question, what format file is "battleship.gfx", and how would you edit it?
Thanks...

Its an outdated version of my MFI proprietary packing format. Not really editable in the easy sense.
I've never had to "de-compile" a resource file before so I have never developed a program to unpack one.

I think I still have all the resource material floating around somewhere though.

I was looking at your code, and got the genius idea (I hope you are picking up on the sarcasm here)
to rename the variables a little less ambiguously to help me follow what the code is doing,
and I seem to have introduced a little bug where when you place a ship on the board, it disappears.
If you have any bandwidth, and could quickly zero in on the line that might be making that happen,
that would be very much appreciated... No pressure or anything, LoL

Besides obfuscating my code, you apparently changed something that must not be changed. What that is I have no clue, but the ships don't actually disappear, they now flicker(faintly) on my machine. So by changing names you have changed the order of operations somewhere and the board now gets drawn over the ships instead of the ships getting drawn over the board. Believe it or not sometimes names matter, when it comes to variables and what not. (no sarcasm, just a grain of salt. take it how you will XD)

Guessing you used the CHANGE ALL command and just bulk changed things? If so, that is certainly what did it. (I have accidentally done similar things) I would suggest you pull a clean copy and if you really, REALLY, REALLY! need to change variable names then use the FIND AND VERIFY option and confirm that each change is in fact the exact variable you are trying to rename. I would highly advise against messing with the LAYER array name. or any names pertaining to Graphics layers (ie variables in _putimage lines, _loadimage lines, or _newimage lines) as they tend to be important.

but reviewing this code, man! there are things which I would never do anymore. to think in only like 2 1\2 years I have found so many better ways to do things. And I never did add sound... :(
but that would be why there is no SFX file. May have just given me a reason to revisit this project an maybe get it up to Ver 1.0(or at least 0.9)
