为什么这样加不进startItem，那个.plist跟png都是亲自压缩的，别的信息都可以提取出来就开始的那个提取不出来。。。。

你看你的图片写错了吧！ CCMenuItemImage::create(“mainmenu_begin1.bng”, 这个是.png的后缀吧

#3

谢谢。。。。我去试试

#4

改了还是出不来。。。

#5

mainmenu_begin1.png你是单独的还是在一张大图里面的，如果是在一张大图里面的话就不能这样用了，就要先用CCSprite加载图片，然后使用CCMenuItemSprite来处理。

#6

我直接新建了GameMenuLayer 跟GameMenuScene 来处理菜单。结果弄出来了，非常感谢你的细心帮助

#7

是存放在一张大图里面的。。。。有。plist

#8

大图的话就不能够使用 CCMenuItemImage，这个主要是小图片使用的。大图需要 CCSprite::createWithSpriteFrameName，嘿嘿解决了就好了哈:14:

#9

谢谢，我又学到了一些东西，对了问你个问题啊，dpi是什么意思？可以在电脑上直接用像素来解释吗

#10

每英寸像素数，在安卓中的话是手机屏幕密度的意思！具体的话还是需要度娘或Google一下。
