我是学生,我正在研究我的最终项目,但我被困住了。我的动作脚本中有一点我无法找到解决问题的方法。我搜索过网络,几乎阅读了所有可以帮助我的网站。但这是我的问题。
我必须在动作脚本中制作Flash游戏。我差不多完成了但是我找不到如何添加验证没有剩余磁贴可供选择的代码。
可以帮助我在哪里放置代码来检查舞台上是否有更多的瓷砖?还有我必须使用的代码吗?
此外,当它检查是否没有留下任何瓷砖且没有留下时,它必须转到第二帧,要求再次播放或返回主屏幕。
我的代码:
package {
// importing classes

// end of importing classes

我的想法是,因为你将tile放在tiles数组中,你可以拥有一些东西,当用户点击tile时你用splice属性从Array中删除了这些东西,所以当array.length属性是零,你可以结束游戏。
p.s不确定splice属性是否是您需要的属性但是这里是actionscript网站,它告诉您有关数组及其属性的所有信息ActionScript 3 Site

我认为这更像是一个快速'黑客',但既然你知道了瓷砖的数量,你就可以创建一个计数器。然后,每次从板上移除一对瓷砖时,将2添加到计数器(每个瓷砖一个)。当计数器与您在开始时拥有的瓷砖数量相匹配时,这意味着所有瓷砖都已匹配,因此从电路板上移除。
