处理。睡眠，等待，超时，暂停，延迟?

Is there a sleep() function for Processing.js? If not what would be a suitable alternative to add a delay in the draw() loop?

是否有一个用于处理。js的sleep()函数?如果不是，那么在draw()循环中添加延迟的合适替代方案是什么?

I am using JQuery with Processing - can I use a JQuery or Javascript function to cause a sleep type delay in the loop?

我正在使用JQuery进行处理——我可以使用JQuery或Javascript函数在循环中导致睡眠类型延迟吗?

Thanks!

谢谢!

Processing has a delay() function but unfortunately that is not implemented into Processing.js yet.

Processing有一个delay()函数，但不幸的是，它没有实现为Processing。js。

You can mix JS(JQuery,etc.) with Processing though. Processing 1.9.9 has a Javascript mode now and there are examples for Processing/DOM integration, like SelectionFlower. In the sketch/pde file there is a method setup to be called form js:

不过，您可以将JS(JQuery等)与处理混合使用。Processing 1.9.9现在有一个Javascript模式，有一些用于处理/DOM集成的例子，比如SelectionFlower。在sketch/pde文件中有一个方法设置为form js:

// called from JavaScript
void setSelectionText ( String txt )
{
    selectedText = txt;
}

and in the js file, a timeout is set to make sure the sketch is initialized and can be accessed:

在js文件中，设置一个超时，以确保已初始化草图并可以访问:

var mySketchInstance;

// called once the page has fully loaded
window.onload = function () {
    getSketchInstance();
}

// this is called (repeatedly) to find the sketch
function getSketchInstance() {
    var s = Processing.instances[0];
    if ( s == undefined ) {
        setTimeout(getSketchInstance, 200); // try again a bit later

    } else {
        mySketchInstance = s;
        monitorSelection();
    }
}

Then when the sketch instance is available, you can simply call a method/function on the sketch:

当草图实例可用时，您可以简单地调用草图上的方法/函数:

function monitorSelection () {
//bla bla
mySketchInstance.setSelectionText(txt);  // set the text in the sketch
}

Here is my solution.

这是我的解决方案。

void waitasec (int sec) {

   int minutes = minute();
   int seconds = second();
   int hour = hour();
   int starttime = (hour * 3600) + (minutes * 60) + seconds;
   int finaltime = starttime + sec;

   while (starttime < finaltime) {

       minutes = minute();
       seconds = second();
       starttime = (hour * 3600) + (minutes * 60) + seconds;
   }
}

A resource consuming solution:

资源消耗的解决方案:

int timer = 0;
void draw() {
 if (timer%50 == 0) {
  //some code here
 }
 timer = timer +1;
}

jQuery

.delay( duration [, queueName] )

.延迟(持续时间[，队列名])

Description: Set a timer to delay execution of subsequent items in the queue.

说明:设置一个计时器来延迟队列中后续项的执行。
