【Unity】デバッグログ無効化と小ネタ

2019/05/16DEVELOP, Unity

ログ出力は思っている以上に重い。なのでリリースビルドだったりでは無効化します。恐らくこれが最も有効な手段で、別名のClassを作らずに済む。

DISABLE_LOG定義を有効にするとデバッグログが一通り消える。

小ネタ、Assertに事前conditionチェック

public static void Assert(bool condition, string message, Object context)
{
    if(!condition)
    {
        UnityEngine.Debug.Assert(condition, message, context);
    }
}

素直に関数を呼ばず、わざわざconditionを見る様にしています。ifの中でブレイクポイントを張っておけば、アサートの条件にヒットした際に簡単にコールスタックが追えます。
