timer

问题 This question already has answers here : Convert int (number) to string with leading zeros? (4 digits) [duplicate] (4 answers) Closed 6 days ago . I created a timer that returns the decreasing time: public static void timerIdle_Tick(object sender, EventArgs e) { if (tempo >= 60) { minuto = tempo / 60; segundo = tempo % 60; } else { minuto = 0; segundo = tempo; } segundo--; if (minuto > 0) { if (segundo < 0) { segundo = 59; minuto--; } } if (minuto == 0 && segundo == 0) { timerIdle.Stop();

问题 I am making an app that tracks the progress of goals. once a goal is complete, hitting 100%, an animation of confetti is displayed, but it won't stop. how would I stop the confetti animation after a certain amount of time? would I use a timer? func displayConfetti() { //creates purple confetti let purpleConfetti: UIImage = UIImage(named: "purpleConfetti")! let emitter = Emitter.get(with: purpleConfetti) emitter.emitterPosition = CGPoint(x: view.frame.size.width / 2, y: -10) emitter

问题 How do I use Tokio to implement a fixed number of timers that are regularly reset and canceled across threads? When a timer expires, a callback will be executed. An API similar to that of Go's time.AfterFunc is essentially what I desire: package main import ( "fmt" "time" ) func main() { t := time.AfterFunc(time.Hour, func() { // happens every 2 seconds with 1 second delay fmt.Println("fired") }) for { t.Reset(time.Second) time.Sleep(time.Second * 2) } } The only crate I've found that

问题 I am developing a Cocoapod library in which, i have to Call a function when timer fires. I am using that Cocoapod in an iOS App, Timer is not firing when App goes to background state private var timer : DispatchSourceTimer? = nil let queue = DispatchQueue(label: "sample.timer") timer = DispatchSource.makeTimerSource(queue : queue) timer?.setEventHandler { [weak self] in self?.sendData() } timer?.scheduleRepeating(deadline: .now(), interval: .seconds(5)) 回答1: The fact that you are using a GCD

问题 I'm trying to create a metronome for Android, and I wrote this code to play a beep at 300BPM using a SoundPool, but it tends to skip beats sometimes and creates lag. I have researched, and all of the answers I have found don't solve my issue. This especially happens when I try to speed up the bpm count or use eighth notes instead of quarter (double time). Can someone guide me in the right direction of making this as accurate as possible? Delay/beat-skipping is not acceptible . Thanks!! final

问题 This is what I have in my paintComponent (most other things omitted, just the stuff that pertains to an Item object called chalice with a polygon field, the explicit parameters of the if statement are not important for this question) Currently, it shows up as solid white because I set the color to all 255, but I want to make it gradually transition to different colors smoothly, not strobing, more like pulsating but I don't really know what that is called. I was thinking about replacing the

问题 So I can see a couple different ways to do what I need and I've done a bunch of google/stack overflow searching but can't find really what I'm looking for. I need to run multiple "Countdown timers." I need to have about 6 possibly up to 10 countdown timers running at once all at different times. I have a tab pane on my main program that I am including the FXML and injecting the controllers into. The Timers Tab has a different controller than the main program. So the 1st question I have is.

问题 I need a survey to auto progress to the next block when a specified time limit has been reached for the previous block. Currently I am using the below script to display the timer but need the script to execute the action when time has elapsed. Any assistance is greatly appreciated. Javascript in timing question. Qualtrics.SurveyEngine.addOnload(function() { var headerCont = document.createElement("div"); headerCont.className = "header-cont"; headerCont.id = "header_container"; var header =
