　　Flash研究：基本的车运动的动画效果基本的运动动画，简单演示车运动的做法。建站学友情提示Fla源文件在文章末尾提供。自己做的判定!大虾们就不用看了,只供新手参考!先看看效果:说明：按键盘的向上方向键然后按向左或向右键可以观看效果代码如下：//定义速度变量varspeed:Number=0;varcar_speed:Number=0;//增加键盘侦听器Key.addListener(_root.road_mc);road_mc.onEnterFrame=function(){//键盘UP键按下if(Key.isDoc._y<-80){road_mc._y+=speed;speed_func();car_speed_func();//trace(speed);\ncar_mc._y>=166?car_mc._y-=car_speed:正常;}else{road_mc._y=-437;}//键盘UP键放开}elseif(road_mc._y<-80){if(speed>=0.25){speed-=0.25;road_mc._y+=speed;//trace(speed)//trace(road_mc._y)}}else{road_mc._y=-437;}//键盘LEFT键if(Key.isDoc._x>76){speed<3?car_speed=speed:car_speed=3;car_mc._x-=car_speed;}}//键盘RIGHT键\nif(Key.isDoc._x<378){speed<3?car_speed=speed:car_speed=3;car_mc._x+=car_speed;//trace(car_speed);}}//键盘DOWN键if(Key.isDoc<331?12下一页[感谢阅读这篇文章，..，]car_mc._y+=5:正常;speed-=2;}else{speed=0;}}//加速"shift"键if(Key.isDop;!this["press"]){this["press"]=true;car_mc.play();speed<150?speed+=50:正常;varThis=this;this["interval"]=setTimeout(function(){\ncar_mc.gotoAndStop(1),This["press"]=false;},5000);//设置延时5000毫秒}};//声明函数,按当前速度渐加functionspeed_func(){if(speed<10){speed+=0.25;}elseif(speed<20){speed+=0.5;}elseif(speed<30){speed+=1;}elseif(speed<50){speed+=1.5;}elseif(speed<80){speed+=3;}elseif(speed<0){speed=0;}}源文件下载：点击这里下载源文件\n上一页12[感谢阅读这篇文章，..，]
