  • Our Lisp game, Eternia: Pet Whisperer is now out on Steam!
    1 project | | 5 May 2021
    Kandria and Eternia both are built on top of the game engine Trial, which I and a few others at Shirakumo have been working on for some years now. Trial itself makes use of a bunch of lower level libraries like cl-opengl, GLFW, pngload, harmony, etc. but a huge amount of the codebase was written by me. If you're interested in its development, I recommend hopping by the #shirakumo channel on the Freenode IRC network. I'd be happy to answer questions there!
  • Idiomatic way to handle non GC objects, i.e. OpenGL textures ?
    1 project | | 16 Apr 2021
    A good way to do it is to keep a staging area of sorts that keeps track of the manually allocated objects and their state. When you allocate you batch all objects to allocate together and then execute the load in one go, updating the records in the staging area. Then, when you're ready to switch to a different scene or whatever, you diff the staging area against the current set of objects that need to be live and deallocate everything else in one go.
