0.7.5-580c is a small update that focuses on improving performance.

Changelog[]

Bug fixes[]

  • Fixed a long-standing bug where objects played their placement animation every time they loaded in.
  • Increased spawn distance of several graphical objects, most notably smelters, to avoid them suddenly appearing too close to the player.
  • Fixed a bug that could cause the appearance of an Obsidian Block wall in a scene from the Undergrounds.
  • Fixed an issue that would allow for duplication of an Ancient Gemstone in a scene from the Forlorn Metropolis.
  • Fixed an issue that would spawn a table inside walls in a scene from the Clay Caves.
  • Fixed an error occurring when a Large Bomb explodes.

Performance[]

  • Reduced the update frequency of several common operations from 30 to 20 updates per second.
    • This performance improvement is especially noticeable on devices that previously could not achieve a stable 30 FPS, and it also reduces the CPU load on dedicated servers by a third.
  • Reworked part of the tile map update to be more efficient in general and also to do more work off the main thread, improving performance when the player moves around.
  • Several improvements to the dungeon generation systems, including a complete rewrite of the algorithms used to place paths connecting different rooms.
    • This reduces lag spikes when exploring the world, especially when encountering large boss dungeons for the first time.
  • Removed several sources of memory reallocations when worlds were loaded from or written to files.
    • These improvements both reduce lag spikes when doing autosaves, and they also remove potential increases in memory usage during long play sessions in large game worlds.
  • Cache various object position values instead of looking them up every frame.
  • Several improvements to how object data lookup is performed.
  • Object sprites used to be spawned as soon as the server deemed they were relevant to a connecting player.
    • This was a frequent source of lag spikes, as large numbers of objects tended to get spawned in a single frame. When possible, spawns are now spread out over multiple frames.
  • Disabled inventory slot animators completely when no animations are active.
    • This is most noticeable when the main player inventory is open.
  • Removed overly cautious object lifetime checks.
  • Decorative Pots and Planter Boxes now only recompute the plant sprite state from scratch when the plant type changes, instead of every frame.
  • Light emitted from the player is now merged into a single light source.
  • Looking up tile data for a single position no longer requires all tile data for the surrounding area to be copied.
  • Save files are now compressed directly in memory instead of while writing to file, reducing the memory usage while an autosave is in progress.
  • Removed expensive string processing during custom scene loading.
  • Shadow updates are no longer processed in areas that are being unloaded.

Other[]

  • The "Hide in-game UI" setting is now reset to "off" (i.e., the in-game UI is shown) every time the game is restarted.
