Releases

cerlib is distributed as a .zip package. Every package contains:

  • The source headers
  • Compiled libraries for all supported platforms
  • Supporting CMake scripts
info

You should only need the Game Template package. During CMake configuration, it fetches the cerlib binaries for you automatically from the server.

The full package is only necessary when you want to build your game offline (without an active internet connection). In that case, simply unzip the package into your game's folder. The game will then use that package instead of fetching it from the server.

Changelog​

Version 0.9.0

This releases focuses on preparation for the initial, major release.

Work was done in terms of performance, stability and quality of life features.

The game template was further improved with better tooling and platform support.

Switch to event-based game architecture​

The Game class now provides methods starting with On... that call arbitrary functions at certain points in time.

For example, a polling loop is now replaced by something such as:

game.OnTick( [](GameTime time ) {
  // Update game logic here, use time as a reference.
} );

Platform support​

iOS and iPadOS are now supported.

Spine integration​

cerlib is now able to load, manage and render Spine assets.

Please note the Spine Editor License Agreement when using the Spine integration.
