CocosCreator h5游戏移动端全屏显示

朱雀 2022-06-02 11:09 867阅读 0赞

文章里的方法主要是针对creator游戏引擎的构建后项目，但是也可以由此文章中的方法，再作针对其他h5游戏引擎的修改，由此借鉴出其他h5游戏引擎的全屏显示。

先来看构建后的文件结构：

![20180111145517497][]

其中，红色框里的文件是需要自定义的，css、dist和img文件夹是creator不会构建出来的，需要自己加上去。index.html是creator构建出来的，我们需要对它进行修改。

再看css、dist和img文件夹里的内容：

![20180111150742822][]

![20180111150943217][]

我们先修改index.html里的代码为：

最后，有一个动态图，引导用户滑动全屏，swipe2.gif：

2019.5.24更新：

有些手机不能用滑动进入全屏，这样的话，我们可以判断页面是不是可以直接点击进入全屏，再调用滑动进入的功能代码。

下面是判断点击进入全屏和滑动进入全屏功能的项目代码链接：
