Knights version 24 released!

I am pleased to announce a new release of Knights!

Quick summary of the changes:

  • Knights standing on a gate will now get killed if the gate closes on top of them.
  • Reduced throwing speed of daggers to be consistent with the original Knights.
  • Fixed a number of bugs (see release notes for full details).

As always you can get the game from the download page which also contains full release notes.


P.S. I also updated the mods on the official server to the latest versions, this applies to the “Rat Rider” and “Toolbox” mods. Thank you to the mod authors for continuing to work on their mods!

Knights update

I haven’t done a Knights update for a long time so I thought I would briefly let people know what’s been going on.

Over the last 2-3 months I have been doing the following:

  1. Moving the Knights server to a new VPS (instead of the home server we had previously). This has delivered better ping times and faster website performance for Knights players.
  2. Updating the Knights codebase so that it works with the latest Visual Studio version. I also investigated using SFML or SDL2 for graphics, but that work is on hold for now (see previous post for details).
  3. Behind the scenes, I have been writing some scripts to help auto-generate the HTML pages for the website. (Previously, I had been manually editing HTML files, which is a pain; now I can just edit “template files” and then use my script to generate the HTML and upload, which is much easier.) This should make it much easier for me to change and update the website in the future.

I have also been thinking recently about updating the game’s website. The design of the front page basically hasn’t changed since the game was first released and it is looking a bit “dated” at this point. I would like to try to improve the style/look of the page and also try to “sell” the game a bit more, highlight what’s good about the game, that sort of thing. Hopefully this will persuade more people to download it πŸ™‚

There are also some bug fixes to do (such as the “dagger bug” reported by KnightRider) which I have not forgotten about.

For those who are interested, I have written a “todo list” for Knights, which looks like this:

  1. Fix gate squishing bug (#194).
  2. Fix dagger throwing.
  3. Update the website front page.
  4. Make the official game server show up as “” instead of “” (I’ve been wanting to do this for a long time, it will require a new server config option though).
  5. Fix the Linux makefile (at the moment it doesn’t quite work right when building the knights server on Linux).
  6. I got a code warning from the new Visual Studio (about “incorrect API usage” in one part of my code), I want to investigate what is going on there.
  7. There is a bug with LAN broadcasts which I want to fix.
  8. I’m planning to write a patch for SFML and send it back to the developers (this relates to something I found while investigating SFML for Knights graphics).
  9. I also want to add a “–pidfile” option to the Knights server (this will make it slightly easier to install the server on Linux machines, it is something that came up while setting up the new server).

As you can see there are quite a few small fiddly tasks (which you always get in game development) mixed in with more interesting things like bug fixes and website updates.

As most people know by now I don’t get a great deal of time to work on Knights, but hopefully I should be able to get the first two items on the list (the bug fixes) done in roughly the next two weeks. At that point I’ll do a new release of the game (so players can have the benefit of the bug fixes) and then continue working my way down the list…

I’ll try to do blog updates more frequently as well πŸ™‚

More graphics library stuff…

Here is a quick update on Knights development.

Unfortunately I have still been struggling with graphics libraries for what feels like ages now.

Last time I posted that I was trying out SFML and have been doing quite well with it. Unfortunately I have found what seems to be a fatal problem – SFML is completely unable to detect keypresses of the “backquote” key (that is, the key above TAB). This is important for Knights because we use that key as a chat key. Unfortunately I haven’t found any way to work around this, so it looks like we won’t be able to use SFML for Knights right now.

I also looked into SDL 2. However, I found the rendering performance to be very slow. It seems that to get decent performance out of SDL 2, you have to be making direct OpenGL calls in your code (instead of relying on the so-called “SDL_Renderer” layer). Unfortunately this would be quite a lot of work (especially since I don’t really know any OpenGL at the moment…) so this is not really feasible for me right now.

Therefore I think the plan will have to be:

  1. I will keep Knights as it always was — i.e. using DirectX on modern windows machines, and using SDL (version 1 – which uses software rendering)Β on Linux or older versions of Windows.
  2. I have made a few changes to my DirectX code — in particular I have removed the dependencies on D3DX and D3DCOMPILER. This should mean that the code will run on any modern Windows machine without any “DirectX runtime library” downloads being required. (I have also put in some simple UTF-8 text handling, but that is another story…)
  3. At some point I will get in touch with the author of SFML to see if the keyboard handling can be improved. That would eventually mean that I could switch Knights over to using SFML on all platforms. Not only would this bring hardware accelerated graphics to Linux (finally!), it would also mean that I only have one lot of graphics code to maintain instead of two, which will make things easier. This is a longer-term goal though.

Knights ADF available

I got contacted a couple of months back by someone who said “I would love to play the original Knights on my old Amiga 500 but I can only transfer ADF Files to it“.

I had no idea people still played Knights on old Amigas (anyone remember setting up the piece of cardboard to divide the screen in two? πŸ™‚ ) but I was happy to help, so I made a bootable ADF from the Aminet version of Knights and sent it to him. The ADF file is now available for download. Enjoy πŸ™‚

Note that to use this you will need either a real Amiga or an emulator. Regular users will probably want to check out the PC version available from

Investigating SFML for graphics…

So, recently I bought a new laptop. And with it being a new year and all, I thought this might be a good opportunity to get back to some Knights development (something that, sadly, I haven’t had much time for these last few months). So, I installed the latest Visual Studio onto the laptop, set up the Knights code directory, and prepared to do some coding…

… and immediately hit a problem. The game would not build. Partly this was because the Microsoft compiler now supports C++11 (the latest version of the C++ language), which caused a few incompatibilities with my code (admittedly this was mostly my fault though!). And partly it was because Microsoft have changed the way DirectX works – in particular, “D3DX” is no longer a supported technology. Unfortunately for me, I had some code that was using D3DX… which now no longer compiles. Grr. (At least on Linux, once you get your code working, it tends to stay working… πŸ™ )

Well, I could just fix my DirectX code, but I thought it would be better in the long run to bite the bullet and set up a proper cross-platform solution for graphics. (The initial reason why I added DirectX support to Knights was just as a quick way of testing out hardware-accelerated graphics on Windows; it was never meant as a permanent solution.)

So, if one is looking for a modern 2D graphics library there seem to be two choices: SDL2 and SFML. I had a look at both of these, it seems to me that they both do roughly the same thing, but they have different kinds of API – SFML tries to be more modern and object-oriented and so on, while SDL is more “old school” with low-level C-style functions and structs and things. Personally I prefer the former, so I decided to try out SFML.

I have to say, I was not disappointed – SFML was very easy to set up and integrate into the game and seems to work very well. Performance was much faster than software rendering, although admittedly slightly slower than I got from my DirectX code (not sure why this is; presumably it’s just the overhead of having an extra library in between you and the graphics card; in any event, it’s not that big a deal and I think it’s a price worth paying given how easy to work with SFML is).

I also had some small keyboard handling problems with SFML (e.g. it seems the ` key – the “team chat” key in Knights – is not recognized, but I think I can work around that).

Overall, therefore, I hope to have the SFML integration work done in the next few days, which means the next version of Knights will support fast hardware-accelerated graphics in both Windows and Linux. (As a side note, there is also a problem on some Windows machines where the Knights DirectX graphics doesn’t work if you don’t have the right DirectX runtime libraries installed… that should also be fixed by the move to SFML.)

Knights version 23 released!

Hi everyone,

I decided that it was about time to do another Knights release (has it really been a year since the last one?), so I have just released version 23.

This is just a small bug-fix update. The main bug that was fixed was that I finally tracked down why the server list page was sometimes showing 0 players online, even when people were online. This turned out to be an overflow problem (basically, after the game had been running a few days, a 32-bit timer would overflow and this would prevent any further updates being sent after that point).

There are also a couple of minor fixes/changes for the Linux build.

Most users won’t need to upgrade, although if you’re running your own server you should upgrade in order to get the server list fix. (I’ve already applied this to the official server.)

Hopefully next year I’ll get a bit more time to work on the game!

The new release is available from the download page.

Knights new version coming soon…

Just a quick Knights update here. I have been away from Knights for a while (sorry about that) but I do have a bit of spare time over Christmas and I intend to use it to make a new Knights release.

The plan is to include the following features (the numbers refer to Trac):

  • Implement the “Monster Proposal
  • #215 – Add GetRespawnFunction to Lua API
  • #203 – Error message or warning if Lua “prefix” forgotten
  • #206 – Update manual to refer to new Boost version
  • #164 – Ability to cycle each observer window independently

Hopefully I can get this done fairly quickly, as I know some people on the forum have been waiting for a new release for some time now…

After that I’d ideally like to get the map editor up and running again, as this would complement the Knights Lua scripting features nicely. This could really open the door for people to make new rooms or maybe even entire custom maps for Knights. That will be a task for next year though πŸ™‚

Knights version 21 released!

A new version of Knights has been released!

This time there are two major new features:

  1. There is a brand new Tutorial level. This should make it a lot easier for newbies to learn how to play. Old timers might also like to play through the Tutorial, as there are a couple of interesting challenges in there πŸ™‚
  2. Lua support has been added. This allows players to make their own modifications (mods) for the game. Already some players have created mods, adding things like spiders, living armours, and a hilarious (imho) new wand type. To see what people are doing, check out the forums.

As usual, head to the download page for downloads and detailed release notes.

P.S. Due to a technical issue the official Knights game server is currently offline. I’ll fix this later today.
