多次执行相同功能后，逐帧播放MovieClip [英] Play MovieClip frame by frame in addition after same function is executed several times

问题描述

我有一个名为fail_mc的MovieClip，它由3个足球组成，在我的游戏中，每当我的玩家失败时，我都需要在1个球上添加X标记，我还有一个hitTestObject来检测球何时击中球门区域，但是当球走到外面时，我需要在failure_mc内打一帧并将X标记添加到球上(我在failure_mc内有3个不同的png文件，每帧上有1个)，这是我正在使用的代码，但我不这样做不知道如何逐帧播放failure_mc(请记住，每次都会使用相同的功能，这就是为什么必须将每帧都添加到最后播放的帧中的原因:

I have a MovieClip named fails_mc, it consists of 3 soccer balls and in my game every time my player fails I need to add an X mark over 1 ball, I have a hitTestObject detecting when the ball hits the goal area, but when the ball goes outside I need to play 1 frame inside the fails_mc and add the X mark to a ball ( I have 3 different png files inside fails_mc, 1 on each frame), this is the code I’m using but I don’t know how to play frame by frame the fails_mc (keep in mind that the same function will be used every time, that’s why each frame must be added to the last played frame:

if (ball.hitTestObject(goalie))
{
    goal_mc.play();
    net_mc.play();
}
else
{
    fails_mc.play(+=1); // This is not working

    trace("It’s a fail");
}

3次失败后，我必须触发另一个可以完成游戏的功能，但是稍后我将弄清楚该怎么做.

After 3 fails I must trigger another function that will finish the game but I will figure out how to do that later on.

推荐答案

我认为您所寻找的只是movieClip的nextFrame()函数.

I think all your looking for is the nextFrame() function of a movieClip.

您还可以使用gotoAndStop("x1")-其中"x1"是您希望movieClip转到的帧标签(如果没有引号，则为数字).您可以使用变量来跟踪当前状态.

you could also use gotoAndStop("x1") - where "x1" is the frame label (or number if not in quotes) you want the movieClip to goto. You could use a variable to track the current state.

var misses:int = 0;

if (ball.hitTestObject(goalie))
{

    goal_mc.play();
    net_mc.play();

}
else
{
    misses++;
    trace("It’s a fail");

    if(misses > 3){
        //do your game over stuff
    }else{
        fails_mc.gotoAndStop(misses)
    }
}
