A Unity demo project that showcases ChainRacePattern (CRP) using Unity-Chan.
- Demo: ChainRaceUnityChan
ChainRacePattern is a design pattern for handling skippable presentation flows in Unity.
It represents animations, input, delays, and other presentation steps as Chains, and composes them declaratively with Sequence, Parallel, and Race.
For the full technical documentation — core rules, design philosophy, sample scenes, and the debug window — see the reference implementation:
This project is a self-contained demo that plays a short Unity-Chan presentation sequence using CRP. It combines:
- Animator state transitions (
ChainAnimator,ChainCrossFade) - Voice playback with subtitles
- Movement tweens via DOTween (
ChainDOTween) - Timed delays composed with
Sequence/Parallel/Race
Use it as a reference for how CRP can orchestrate character animation, voice, and movement in a real scene.
ChainDebugWindow is an editor window that visualizes the state of the entire Chain tree in real time while the game is playing.
Open it from Window > Chain Debug.
To use it, call ChainDebugWindow.Watch(chain) from your game code to register the root Chain to watch.
void StartChain()
{
var chain = new ChainSequence(/* ... */);
ChainDebugWindow.Watch(chain);
chain.Start();
