Actionscript 3 AS3垂直射手：鼠标单击不工作
我只是试着制作一个简单的垂直射击游戏，玩家的飞船由鼠标控制，当你点击鼠标时发射激光。但是，当我尝试运行代码时，我不断收到相同的错误消息： “1046:找不到类型或类型不是编译时常量：MouseEvent。” 问题是，我宣布了MouseEvent。我知道我做到了。详情如下: --==-- { 导入flash.display.MovieClip 导入flash.utils.Timer 导入flash.events.TimerEvent 导入flash.events.MouseEventActionscript 3 AS3垂直射手：鼠标单击不工作,actionscript-3,flash,mouse,Actionscript 3,Flash,Mouse,我只是试着制作一个简单的垂直射击游戏，玩家的飞船由鼠标控制，当你点击鼠标时发射激光。但是，当我尝试运行代码时，我不断收到相同的错误消息： “1046:找不到类型或类型不是编译时常量：MouseEvent。” 问题是，我宣布了MouseEvent。我知道我做到了。详情如下: --==-- { 导入flash.display.MovieClip 导入flash.utils.Timer 导入flash.events.TimerEvent 导入flash.events.MouseEvent public
