    Project mention: Openage Development 2022: September | | 2022-09-30

    In August the Definitive Edition of AoE2 received an update that changed its default graphics files from the previously used SMX format to the new SLD format. Since the AoE2 devs did not publish any information about the format, we had to reverse engineer it ourselves (together with Tevious from SLX Studio, spriteblood from Overreign and simonsan from the LibreMatch project). You can find the reversed specification in the openage repository (Link).

  • tiled

  • MonoGame

    One framework for creating powerful cross-platform games.

    Project mention: Which game engine should i use for 2D games? | | 2022-11-20

    MonoGame is a great way to make 2D games. It's not an authoring tool and depending on what you want to do a fully fledged game engine may be a better choice, but "I want to make a 2D, point me to an engine" is very unspecific. If you could eloborate more what you want to do, the suggestion would also be more profound. Game Engines are just tools and choosing one over another is not something a beginner should really care about that much. But I bet, using MonoGame will be a great learning experience, boost your programming skills and switching to a game engine later will be easier than the other way around.

  • Cataclysm-DDA

    Project mention: Physical strength should be overhauled on how it is affected by the stat and mutations. | | 2022-12-01

    At the very least, I can say that 15 strength isn't superhuman, that would be >20. Here is a link to one of the development documents that articulates what each level of strength is supposed to mean. Hulks in this system would have much more than 20 strength, considering they can shove cars around and are "the size of 6 men." You're not likely going to match a hulk's strength even as a top-tier bear mutant without debugging or mods cuz hulks are just bigger than bears.

  • Ebiten

    Ebitengine - A dead simple 2D game engine for Go

    Project mention: crten - a small tool to view your pixel art with a CRT screen effect | | 2022-11-15
