推荐答案

这不是针对coco2d的。

It's not specific to coco2d.

这是一个lambda捕获列表。使变量可用于lambda。您可以使用[=]按值复制，或[&]通过引用传递。

It's a lambda capture list. Makes variables available for the lambda. You can use [=] which copies by value, or [&] which passes by reference.

您还可以使用[]不捕获任何内容。

You can also use [] which captures nothing.
