CE DevTools

CE.DevTools provides runtime debugging helpers: logging, an in-world console, and lightweight profiling.

Quick Start

using UdonSharp;
using UdonSharp.CE.DevTools;

public class ProfilerExample : UdonSharpBehaviour
{
    public CEProfiler profiler;

    void Start()
    {
        profiler.StartProfiling();
    }

    void Update()
    {
        profiler.BeginSection("AI");
        // ... AI work ...
        profiler.EndSection();
    }
}

Notes On CELogger Transformation

CELogger calls are transformed into Debug.Log calls during Udon compilation. This keeps Udon compatibility but means MinLevel filtering and in-world console integration are not applied automatically in compiled Udon code. If you want logs to appear in a CEDebugConsole, call AddLog directly or implement a custom bridge.

CEDebugConsole expects UI references to a TextMeshProUGUI or Text component and an optional ScrollRect. A prefab is available in Packages/com.merlin.UdonSharp/Samples~/CE/DebugConsole/.

Common Pitfalls

Bad

CELogger.MinLevel = LogLevel.Warning;
CELogger.Info("This still logs in Udon-compiled output due to transformation");

Good

// Use CELogger for editor readability, or call CEDebugConsole.AddLog for in-world display.
