Frequently Asked Questions

What is the current state of development?

Luxinia is currently not a full-time project for game middleware use. It is mostly used in research for the authors' personal work, or free-time experiments with game ideas or rendering techniques. Therefore development and goals undergo quite some fluctuations.

Luxinia1 has ceased in its active development, but if you want to have fun with a lua-scriptable game engine, try it and play around. If what you get is sufficient for your needs, you can consider commercial development with luxinia "as-is". If you need things beyond this (guaranteed support, certain features...) a snapshot of luxinia's source is available.

There is also luxinia2, a new and more loose framework being developed for luajit2 (less game-centric).

Can I have/buy the c-source code of Luxinia?

Yes, we have a free SDK for download.

What about Linux and Mac Os X support ?

We intend to provide both Linux and Mac ports. Priority for the ports is relatively low.

Can I release Luacode under the terms of the GPL

If you are using the Free License the answer is no. If not, you can do so. The reason is, that we provide the engine for free to let the whole community benefit and not only the ones who are using the free license anyway - any code you deploy in readable from with the free version should be able to be put into a commercial product. If you don't like this, you can pre-compile the lua sources.

I need the feature ... - can you add it please?

It depends on the kind of the feature, how complicated the feature is and how usefull it is. You can ask for features but there's no guarantee that we add a certain feature.

What kind of games can be made with Luxinia?

Anything but (complex) egoshooters or huge simulations with very complex scenes (many entities, physics.. luxinia is not crysis).

Can you make me a game?

Depends on your paying(!).

Luxinia doesn't start, can you help me?

Unfortunately not really. Make sure that you have the latest drivers for you graphics adapter. Luxinia requires at least a GeForce? 1 and a processor with at least >500 Mhz or equivalent. You may see some errors in the luxinia.log regarding a failed start.

What about the source codefiles in the scripts directory of Luxinia? What license are they?

Consider the source that is published with MIT license. Simply forgot to write a header in these files.

Can I modify the ... demo from the default package and sell it?

No. You can use the code, but not the artwork. If you are interested in modifying the xmas game for sponsoring purpose you must contact us. As said before: The code is free but the artworks keep their copyright and may not be distributed without the authors permission.

Can I port Luxinia to other platforms?

Yes should be doable with the SDK.

How is the performance on older machines ?

We did a little benchmark with version .94 on a Pentium3 500 MHz?, 128 MB RAM, Geforce2 MX100?/200 AGP 2X 32 MB.
640x480x32 windowed (fullscreen should give some extra fps).
Clocking the cpu at 333 MHz? resulted in a loss of 5-10 fps.

Xmas:
1200 Static objects
5.5 MB Texture memory used (compressed, uncompressed about 16 MB)
Most surfaces single textured and lit by one vertexlight, but also several multitextured surfaces, 1 shadow texture projector, fog enabled for all surfaces

  • GameScene? (Santa flying above):
    ~ 350 visible objects, 35.700 triangles, 650 particles, 2 animated and 2-weight skinned characters with approximately 20 bones each.
    25 fps
  • CarTest? (Truck driving):
    ~ 250 visible objects, 30.000 triangles, 600 particles, 5 physics-controlled objects (truck)
    28 fps
  • CarTest? Far (camera moved away to look down on full city):
    ~ 800 visible objects, 100.000 triangles, rest as above
    18 fps
Actinoids
130 objects, non-textured, vertex-lit by one light.
  • level 1:
    1800 triangles, 38 physics controlled objects
    2-5 active physics objects 30-60 fps, 10-20 active objects 10-20 fps. Physics load depends a lot on inter-collisions between objects.
