timer

问题 My friends and I who are trying to create a game want to use a timer as a way of scoring players, and so we want to display an on-screen timer starting at 0 at the start of the game and stopping when they finish the game. I have looked at some other posts as well as on the android dev website into using a Handler and a Runnable object in order to make it work as I want, but as of right now the run() method inside of the Runnable object is being completely skipped over, so nothing is being

问题 Im using STM32F429 board and my ultimate goal is to get ADC conversion(set to deliver 2.7Ksps or 2.7 samples every 1ms) using TIM8 trigger, collect 1000 samples in buffer and do DMA transfer every second. I managed to get Timer running, but for some reason ADC conversion is not triggered. Without timer ADC is running well and DMA working (just not every 1ms, but faster). APB2 Timers clock is 168Mhz. APB2 Peripherals clock is 84Mhz. TIM8 init function: void MX_TIM8_Init(void) { TIM

问题 Is there any way to do this? This is for a simulator I'm making. I want it so that when the counter(numTimes) reaches 139, it stops the timer. I tried delcaring but no initializing the timer before the Action Listener and stopping the timer within the actionPerformed function, but it gave me an error. I don't want to use another method(but if it works better then I'm all for it), and the while loop at the bottom causes the program to freeze? How can I make this work? ActionListener

问题 Hello Good day i want to create a "Reset Button" where my Timer will reset. I created a new button and named it as "reset" and i use the code "tm2.restart();" but its not working in my created New Button. This is my code: import javax.swing.Timer; public class deploy extends JFrame { private int seconds; private SimpleDateFormat df; private boolean isRunning; private JLabel lblTimer1; private JButton btnStart1; public deploy() { lblTimer1 = new JLabel("New label"); lblTimer1.setForeground

问题 I want a countdown timer to tick faster as the time counts down. the 'tick' is a very short audioclip. I've got the timer working which calls playTickManager() every frame. However with this implementation, at some transitions of cancel/re-invoke, the gap between ticks is inconsistent or overlaps causing an unnatural sounding tick. Is there a better way to implement this without speeding up the actual audioclip, thus maintaining pitch etc? // This is called every frame by the 'timer' script

问题 So I'm having trouble figuring out how to trigger a Timer interrupt (Every 200 cycles) and a button interrupt. When I hit the button interrupt all it seems to do is temporarily pause the counter for a split second and then continue counting. Then it never registers another button interrupt no matter how often I click it on PLP. What the button interrupt is suppose to do is set the register $a1 to 1 (or a non zero number) which is suppose to reset the counter. The Timer interrupt is suppose to

问题 I need help setting up a specific type of timer for my application. My scenario is this: I want to run a timer at a specific time of day (say 4:00AM). That timer then executes a number of different events that each go off and grab data from a database and process it (using background workers). All the different events take different times to finish (could be 30 seconds, could be 5 minutes). I want to continuously enter the timer event every 5 minutes thereafter checking if all events have

问题 I launch a timer only one time in my application: CustomTimer timer = new CustomTimer(mod); timer.Interval = interval.TotalMilliseconds; timer.AutoReset = false; timer.Start(); So the AutoReset is set to false. At the end of the timer, will the dispose method be called automatically? 回答1: No it will not. AutoReset will simply state whether the Elapsed event should be triggered each time the interval elapses, or only the first time. You can e.g. hook up an event handler to the Tick event and

问题 I'm making pong in java If the ball goes out of bounds, pause is set to true : if (ball.getX() <= 0) { score2++; pause = true; } if (ball.getX() >= this.getWidth()-ballWidth) { score1++; pause = true; } which should sleep the timer... after the thread has slept for 1000ms, pause will be set to false and the ball should continue moving ( ball.autoMove() ): public void timer() { int initialDelay = 1000; timer.scheduleAtFixedRate(new TimerTask() { public void run() { if (pause) { try { ball

问题 I have 2 global System.Windows.Forms.Timer in my form . Both are initialized in form's constructor. But not started yet. Constructor starts a new thread and that thread enables and starts both of the timers. Obviously it is all cross threading , but it doesn't throw any cross-thread exception. But it doesn't even work. It does not fire the Timer.Tick method. Here is the code: 1st Method: In form constructor: KeepMeAliveTimer = new Timer(); //timer 1 KeepMeAliveTimer.Interval = 15000;
