【Unity】Debug.Assert と Debug.LogAssertion は Development Build の時のみ動作する

概要

• Debug.Assert と Debug.LogAssertion は Development Build の時のみ動作する
• Development Build ではない時にも動作させたい場合は
  BuildOptions.ForceEnableAssertions を使用する

using System.Linq;
using UnityEditor;

public class Example
{
    [MenuItem( "Tools/Hoge" )]
    private static void Hoge()
    {
        var options = new BuildPlayerOptions
        {
            scenes           = EditorBuildSettings.scenes.Select( x => x.path ).ToArray(),
            locationPathName = "app.apk",
            targetGroup      = BuildTargetGroup.Android,
            target           = BuildTarget.Android,
            options          = BuildOptions.ForceEnableAssertions, // ★
        };

        BuildPipeline.BuildPlayer( options );
    }
}

検証用スクリプト

using System.Text;
using UnityEngine;
using UnityEngine.UI;

public class Example : MonoBehaviour
{
    public Text m_text;

    private readonly StringBuilder m_builder = new StringBuilder();

    private void Start()
    {
        void OnReceived
        (
            string  condition,
            string  trace,
            LogType type
        )
        {
            m_builder.AppendLine( condition );
            m_builder.AppendLine( trace );
            m_builder.AppendLine( type.ToString() );
            m_builder.AppendLine();
        }

        Application.logMessageReceivedThreaded += OnReceived;

        Debug.LogAssertion( "LogAssertion" );

        Debug.Assert( false, "Debug.Assert" );
    }

    private void Update()
    {
        m_text.text = m_builder.ToString();
    }
}
