Build Test Log - Foxtrot Engine, 2025.10.11


Build test for October 11th, 2025 is completed. Here is the list of features added or improved for Foxtrot Engine.
Now that most of the core features are done, Foxtrot Engine is being developed along with SPARED BOY, a 2D action side-scroller by GooCat Studio.

Added Features

  1. Spine animation Component is much more stable now.
    • Resolved errors - attachments under skin placeholders are not rendered.
  2. Animation-related resources have front direction value.
    • This will allow animated characters or props to flip themselves based on where they are heading.
  3. Bugs were fixed, allowing enhanced stability.


Since the Foxtrot Engine is primarily built for GooCat Studio, the build process is not that intuitive for a beginner willing to use the engine.

The following is the result of today’s build test: a player character (you can call him “Henry”!), and the wolf alien chasing him.

Stay tuned for more!
