unity获取text中每行字体占据的宽度

通过检测每行字符所占据的总宽度，就可以判定所需的text对象、字体是否可以缩放

 private void GetRowTextWordWidth(Text text){string[] textArray = text.text.Split('\n');float width = 0;for (int i = 0; i < textArray.Length; i++){      TextGenerator tg = text.cachedTextGeneratorForLayout;TextGenerationSettings settings = text.GetGenerationSettings(Vector2.zero);width = tg.GetPreferredWidth(textArray[i], settings) / text.pixelsPerUnit;Debug.Log("该行字体宽度为："+width);}}
