我正试图在flash中创建一个类似植物大战的僵尸游戏。当我把“A”放在“B”上时，它开始射击子弹。我们被告知仍应允许对象转移到“C”。但是，当我尝试在“C”上转移“A”时，子弹仍在“B”上。从“B”中删除“A”后，如何从“B”中删除子弹？
答案 0 :(得分：0)
如果没有看到你的代码，很难弄明白你的错误。
然而，这是一个工作植物大战僵尸来源，可能会帮助你的努力。
创建名为＆＃39; pvz.fla＆＃39;的Flash文件将其课程设置为＆＃39; Main＆＃39;然后保存。 在pvz.fla的库中创建5个MovieClip bulletMc plantMC selectorMC 的SunMC zombieMC
在每个MC中绘制适当的图像。 确保所有MC在其属性中都有Actionscript Linkage。 使链接命名相同的MC名称，例如。 bulletMc plantMC selectorMC 的SunMC zombieMC
接下来创建一个名为＆＃39; Main.as＆＃39;的动作脚本文件。 在Main.as中放入以下代码。
