Unityで動作しているPCの情報を取得できるSystemInfoというクラス

なぜ

複数のプラットフォームやスペックによっては機能を制限しなきゃ動かないことがありますよね。
その時の解決手段の一つとして動作するPCの情報を所得してそこから判別させるというものがあります。
UnityではSystemInfoというクラスがその情報を保持しているようだ。
早速みていこう

デバッグログに表示させる

コード

  private void Start()
    {
        LogAllSystemInfo();
    }

    private void LogAllSystemInfo()

• コア数や周波数によって機能を最適化
  などなど、色々使い道がありそう。
