问题 In traditional embedded programming, we will give a delay function like so: for(i=0;i<255;i++) for(j=0;j<255;j++); In the microprocessor's view, is this how the sleep() function works? Is there an alternative for the sleep() function in C? 回答1: Alternatives depend in what you are trying to do and what OS you are on. If you just want to waste time, then these might help: On most unix-type systems you'll find a 'usleep' function, which is more or less like sleep with greater resolution. Be

问题 This question already has answers here : High-precision clock in Python (13 answers) Closed last year . I finally figured this out and would like to share the knowledge and save someone a bunch of time, so see my answer below. However, I still need answers for Linux, so please answer if you know, as my code in my answer is for Windows only. UPDATE: I've figured it out for Linux too, including for pre-Python 3.3 (ex: for the Raspberry Pi), and I've posted my new module/code in my answer below.

How to create a delay in Swing

问题 I made a blackjack game, and I want the AI player to pause between taking cards. I tried simply using Thread.sleep(x), but that makes it freeze until the AI player is done taking all of his cards. I know that Swing is not thread safe, so I looked at Timers, but I could not understand how I could use one for this. Here is my current code: while (JB.total < 21) { try { Thread.sleep(1000); } catch (InterruptedException ex) { System.out.println(\"Oh noes!\"); } switch (getJBTable(JB.total, JB

问题 ) I\'m in a process of creating a memory game. My problem is that whenever i click for the second time, i can\'t even see toggled button. To be clear - first click toggles the togglebutton, so i can see the number it holds, the second click on a different togglebutton is suposed to toggle it, show me the number and then proceed to either set a score +1 if numbers are the same, or reverse them back again if they\'re different. Below is the code that i use as my onClick function, i\'ve been

Proper way to wait for one function to finish before continuing?

问题 I have two JS functions. One calls the other. Within the calling function, I\'d like to call the other, wait for that function to finish, then continue on. So, for example/pseudo code: function firstFunction(){ for(i=0;i<x;i++){ // do something } }; function secondFunction(){ firstFunction() // now wait for firstFunction to finish... // do something else }; I came up with this solution, but don\'t know if this is a smart way to go about it. var isPaused = false; function firstFunction(){

Is setTimeout with no delay the same as executing the function instantly?

问题 I am looking at some existing code in a web application. I saw this: window.setTimeout(function () { ... }) Is this the same as just executing the function content right away? 回答1: It won't necessarily run right away, neither will explicitly setting the delay to 0. The reason is that setTimeout removes the function from the execution queue and it will only be invoked after JavaScript has finished with the current execution queue. console.log(1); setTimeout(function() {console.log(2)});

问题 I want to pause my app at a certain in point. In other words, I want my app to execute the code, but then at a certain point, pause for 4 seconds, and then continue on with the rest of the code. How can I do this? I am using Swift. 回答1: Instead of a sleep, which will lock up your program if called from the UI thread, consider using NSTimer or a dispatch timer. But, if you really need a delay in the current thread: ... { sleep(4) } This uses the sleep function from UNIX. 回答2: Using a dispatch

How can I delay a :hover effect in CSS?

问题 Is there a way to delay the :Hover event without using JavaScript? I know there is a way to delay animations, but I haven\'t seen anything on delaying the :hover event. I\'m building a son-of-suckerfish like menu. I\'d like to simulate what hoverIntent does without adding the extra JS weight. I\'d prefer to treat this as a progressive enhancement and not make JS a requirement for using the menu. Example of menu markup: <div> <div> <ul> <li><a href=\"#\"> <ul> <li></li> <li></li> </ul> </li>
