Question

在PlayN1.3.

TextFormat textFormat = new TextFormat(myFont, textWidth, Alignment.LEFT, colorCode, Effect.shadow(-16777216, shadowX, shadowY));

所以我把它改成这个:

TextFormat textFormat = new TextFormat();
textFormat.withFont(myFont);
textFormat.withWrapping(textWidth, Alignment.LEFT);

我现在不想有影子, 但我没有像结果一样得到前身。等待, 不要现在思考。然后我把这个代码改成了这个:

TextFormat textFormat = new TextFormat().withFont(myFont).withWrapping(textWidth, Alignment.LEFT);

It gives me result as previous except shadow which i dont care now.If i am not wrong this is one line representation of above code.Is not it? So why it worked and above code did not.Any conceptual difference is there? Anyone can explain please!

/注:不要担心变量(文字Width、MyFont),这些变量与这些变量无关。

文本格式对象不可更改。当您调用文本Format. with Font( MyFont) 返回一个 new TextFormat 实例, 上面的代码正在丢弃它。如果您想要第一个代码工作, 您需要这样写 :

TextFormat format = new TextFormat();
format = format.withFont(myFont);
format = format.withWrapping(textWidth, Alignment.LEFT);
