Multiplayer Planet Trading Game [Kroynet] - Update 4: 02/01/15

WIP games, tools & toy projects
#1

I’ve recently been messing around with the Kryonet library and decided to make a multiplayer, planet trading game. Inspired by Eve Online and Tribal Wars. This started out as a server/client test; but turned into a slightly functional, pretty ugly looking game.

I’ve been making this up as I go along, but here’s what I’m planning. Some of these points have been already implemented.

  • The server generates a galaxy which contains regions.
  • Regions contain sectors and sectors contain star systems. Star systems can spawn with 0-5 planets.
  • Planets have types (Gas, lava, ocean, terran, etc), different types spawn different resources.
  • When a player logs in for the first time, they are assigned a random starting planet.
  • They have to build factories to harvest the resources and turn them into goods.
  • Goods are used to build factories and can be traded.
  • Players can trade goods and planets.
  • The server dynamically loads in items, resources and buildings from text files. Allowing the server to be highly customisable.
  • Generates in a vaguely-galaxy-like-shape.
  • Local system map which displays planets in star system.
  • And thats all I have so far…

A small galaxy (0.2mb) with the 487 planets in 164 star systems takes 2.95 seconds to generate. A larger galaxy (6.4mb) with 15,203 planets in 6133 systems took 76 seconds to generate.

EDIT:
Instead of attaching big ass pictures to this post, I’ll give you the link to an imgur album: http://imgur.com/a/KHQFX. I will be updating this with the latest images. I’ll attach any small images that will fit on this post.

I’m not to sure what kind of resources,goods or factories I could have.

What I’d like to add

  • Proper GUI, currently I’m using Java Graphics to render everything.
  • Random events, natural disasters?
  • Guilds/corporations/groups. Players join together to pool their resources.
  • Maps. Render the local map to find nearby planets and players.
  • Ships/transport ships. Transport goods between planets? Attack player owned planets? Scout out other planets for resources?
  • Highscores. List of all players and their total worth? Player profiles?

I may be biting off more than I can chew here, but its a fun project. I’d love to hear your suggestions/comments/criticism. I’ll release the source code when I am less ashamed of it, its very messy and I just want to get the functionally working.

Thanks!

Update 1: 10/12/14

  • Game now loads in resources from text files, populates planets with them.
  • Game also loads factory types, can now build factories on planets.
  • Tested connecting to a remote computer (gave friend a client), not local host. Successfully connected to my server!
  • More to come soon.

This is how the server generates the galaxy:

We can’t really give proper feedback without ability to try the game, but it looks pretty good, from what I see here!

#3

I’d love to get my hands on this one! keep updating, and hopefully get a download up (:

#4

I’ll get a download up soon hopefully, though I’m pretty busy at work over Christmas. I’m glad you guys like it so far!

#5

Just posted an update video above (May still be processing).

#6

Sweet. may i ask what your plans are in terms of visuals. this is a cool concept on its own, and many visual applications could work with it.

#7

At the moment I’m going to stick with using Java 2D graphics, but I’d like to switch to something like LWJGL for the UI.

#8

Seems like a really cool idea! you should also make it so the factory’s cost to run to add more dificulty

#9

Thanks! I’m glad you like it, I am thinking of doing something like that. Probably need energy to run (not credits if that what you meant), like solar power maybe.

#10

New update video in the first post, progress made with the marketplace.

#11

What network lib are you using, i have been hunting around for a good one. I gave up on kyronet because it was laggy and am currently using jexxus but it is only a basic framework with hardly any flexibility

#12

Kryonet? Laggy? Weird! I’ve used it before and it worked perfectly.

#13

It only sent a a packet to see if the server was alive and the lag on the server end was crazy

#14

I’m using Kryonet. How was it lagging like crazy?

#15

I was useing a slightly old build and i found a while loop in a while loop in the lib and it was causing hell on my server, i fixed it now :slight_smile:

#16

I seen, i feel like a mong after posting it xD, if posible could i see one of your send/request classes so i can see how more complex ones are structured?

#17

In my Server/Client listeners received(Connection c, Object o) methods I have lists of:

if(o instanceof PacketType){
    //Something
    return;
}

Not sure of any other way I could do it.

#18

Thanks man! now i cant seem to get a connection to last fml :L
00:00 INFO: [kryonet] Connecting: localhost/127.0.0.1:54555/54777
00:00 INFO: [kryonet] Connection 1 connected: localhost/127.0.0.1
00:00 INFO: [kryonet] Connection 1 disconnected.

#19

Lets have a look at your code?

#20

I fixed ot, after a lot of trials and tribulations i realised my timeout was wayyyy to low and now i am pinging a keep alive packet to keep them both connected
