Processing.js - Sleep, Wait, TimeOut, Pause, Delay?
提问by logic-unit
Is there a sleep() function for Processing.js? If not what would be a suitable alternative to add a delay in the draw() loop?
Processing.js 有 sleep() 函数吗？如果不是，在 draw() 循环中添加延迟的合适替代方法是什么？
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 和 Processing - 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，但不幸的是它还没有在 Processing.js 中实现。
You can mix JS(JQuery,etc.) with Processing though. Processing 1.9.9has a Javascript mode now and there are examples for Processing/DOM integration, like SelectionFlower. In the sketch/pde filethere is a method setup to be called form js:
不过，您可以将 JS（JQuery 等）与 Processing 混合使用。 Processing 1.9.9现在有一个 Javascript 模式，并且有 Processing/DOM 集成的例子，比如SelectionFlower。在Sketch/pde 文件中，有一个名为 form js 的方法设置：
// 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，设置超时以确保草图已初始化并可访问：
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:
然后当草图实例可用时，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:
一个消耗资源的解决方案：
int timer = 0;
void draw() {
if (timer%50 == 0) {
//some code here
}
timer = timer +1;
}
