Re: [Freeciv-Dev] Freeciv web client
Awesome. With those latest usage stats posted elsewhere, it seems you're on to something big here, Andreas. :) Took the opportunity to post a 'community news' blurb over at the freeciv.org wiki: "Freeciv Web Client developer Andreas Røsdal reports that over the last month, an impressive 1254 games have been played on his servers. The Web Client has been recently updated, so if you're running a recent version of Firefox, Safari, or Chrome, surf over to http://www.freeciv.net/ and join in."

Some solution for this should be found. - In the current web client has the mapview rendering logic on the server side (in the civclient C process), and transmits which tiles are supposed to be drawn to the client using compressed and diffed JSON. I think that this has to be changed to that the client side Javascript contains more game logic, and is able to draw the entire mapview based on game data stored in variables on the client. Initially, I wanted the client side Javascript to be as think and lightweight as possible, and simply to operations sent from the server. This has proved to be too slow, because too much data was transmitted over the network. To sum up: more game logic and game data needs to be implemented on the client side, so that network traffic between the server and Javascript web client is more like between the current C civserver and civclient.

For example, if the main architecture is sane and can perform and scale sufficiently to host real games online. At the moment there is a some delay between events on the server and what is rendered in the web client. This is very noticable when many units are moving. Perhaps more of the rendering logic should be moved to the Javascript part of the code. Also, anything which can be done to reduce the resource usage (memory, CPU, bandwidth) will help to make it more scalable... Once enough functionality is ready, I think it would be exciting to setup a real server with the web client running on it.

Re: [Freeciv-Dev] Freeciv web client
I think that I should write some documentation about how to setup and run
the web client, because currently that takes a lot of effort. Each
web-browser session gets its own civclient process. The civclient
process is launched from the Java application server (Resin), and at the
moment the civclient can only be run from the command line for debugging
purposes if it is invoked with correct parameters. So you really have to
setup the application server correctly first, before you can get the whole
thing running.
The data directory was left out because I don't have any more storage
space on the server. I would be really great if a new branch could be
created in SVN on gna.org for this "experiment". Otherwise it would be
difficult to share the source code.
Anyway, it's great that you gave it a try, event though there is still
quite a long way to go.

Now I've implemented a prototype / proof of concept. It uses a webservice which allows a browser to communicate with a civclient process on the server. The mapview is renederes using the canvas element which is drawn upon using Javascript. That is impressive. When you posted the original proposal, I thought it was silly because surely it could never work... Does this mean the player does not have to download anything to play? Correct, nothing is required in order to play, except for a compliant web browser. However, the entire javascript client, tileset and data will have to be downloaded by the web browser. Currently 1,2 MB of files are downloaded in this way. This is compressed with gzip. In addition there is the constant polling of the server from the client to keep it updated. Most of this file size is because of the large png files in the tileset, with a lot of wasted space. The performance still has a way to go, perhaps someone has some suggestions. How bad is it? Initializing the client currently takes about 30 seconds. This includes downloading everything, cropping and preparing the tileset, and starting a civclient and civserver process. Rendering the mapview on the canvas element is now at about 7 fps, which includes the time it takes to poll the server for coordinates to render, and rendering the graphics to the canvas element. This framerate will increase a lot if more clever caching of the map is used in the client, and the framerate will probably decrease once more complex maps are rendered (with fog etc). Thinking out more clever ways to transfer and render the map to the client would be a good idea. The server side appears to perform pretty well, each civclient requires about 5 MB of RAM, and not very much CPU power. So I would imagine that quite of lot of clients could use the same server, perhaps over 100 simultaneous users. What is needed to set it up? This can be run using a Java application server, I'm currently using Resin (www.caucho.com). You also need Apache Axis and libcsoap, including their dependencies. I might write up a description about how to deploy this. Or even setup a test-server once I'm satisfied with it. - Andreas___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev
