我正在尝试合并两个程序。一个用于播放介绍视频的视频播放器，另一个用于显示雷达（我在网上找到了编码）。我想要做的是，首先播放视频，这是对雷达的介绍，然后显示雷达。雷达显示器与Arduino Mega 2560相连，并且有自己的编码。这是两个代码。
import processing.video.*;
String PATH = "D:\\FullZord.mp4";
Movie mov;
void setup()
{
size(1920, 1080);
frameRate(30);
mov = new Movie(this, PATH);
mov.play();
mov.speed(1);
mov.volume(10);
}
void movieEvent(Movie m)
{
m.read();
}
void draw()
{
image(mov, 0, 0, width, height);
}

您必须阅读视频库的参考资料。您正在寻找一种方法来检测电影何时播放，或者何时停止播放。它可能类似于isPlaying()类中的Movie函数。
如果有，可以在draw()功能中调用它来检测电影是否仍在播放。如果是这样，请画出来。如果没有，那就显示雷达。
但要小一些。首先，你可以在电影播放完成后向控制台打印一些东西吗？建立起来。
另外，我强烈建议您不要只使用从互联网上复制粘贴的代码。这只会给你带来很多麻烦。相反，尝试准确理解代码正在做什么。否则，它将无法调试或进行更改。在使用它之前，您需要真正理解代码。

解决了！我刚刚使用了延时功能。这个。
if (millis() > 1000) {
// do something
}
