sleep

I'm incredibly new to programming, and I've been learning well enough so far, I think, but I still can't get a grasp around the idea of making a delay the way I want. What I'm working on is a sort of test "game" thingy using a Windows forms application that involves a combat system. In it, I want to make an NPC that does an action every couple of seconds. The problem is, I also want to allow the player to interact between attacks. Thread.sleep really doesn't seem to work for me not only because I don't know how to multithread, but whenever I try to run it, say, like this: textBox1.Text += "\r

In NetBeans, there's a new hint that says: Thread.sleep called in loop. Question 1: How/when can it be a problem to sleep in a loop? Question 2: If it's a problem, what should I do instead? UPDATE: Question 3: Here's some code. Tell me in this case if I should be using something else instead of Thread.Sleep in a loop. In short, this is used by a server which listens for client TCP connections. The sleep is used here in case the max number of sessions with clients is reached. In this situation, I want the application to wait until a free session becomes available. public class SessionManager {

Is there a notion of sleep stages/levels on Android? From browsing the mailing lists, I'm aware that there exist a stage called "Deep Sleep". Do execution for all apps halt when device reaches this state? If so, besides user hitting the power button, what else could wake the device back up? CommonsWare From browsing the mailing lists, I'm aware that there exist a stage called "Deep Sleep". There is not really a separate stage called "deep sleep". There is only "awake", "asleep", and "off". Do execution for all apps halt when device reaches this state? Execution of all processes ceases when the

Now there's something I always wondered: how is sleep() implemented ? If it is all about using an API from the OS, then how is the API made ? Does it all boil down to using special machine-code on the CPU ? Does that CPU need a special co-processor or other gizmo without which you can't have sleep() ? The best known incarnation of sleep() is in C (to be more accurate, in the libraries that come with C compilers, such as GNU's libc), although almost every language today has its equivalent, but the implementation of sleep in some languages (think Bash) is not what we're looking at in this

How do you tell a Ruby program to wait an arbitrary amount of time before moving on to the next line of code? rcoder Like this: sleep(num_secs) The num_secs value can be an integer or float. Also, if you're writing this within a Rails app, or have included the ActiveSupport library in your project, you can construct longer intervals using the following convenience syntax: sleep(4.minutes) # or, even longer... sleep(2.hours); sleep(3.days) # etc., etc. # or shorter sleep(0.5) # half a second Use sleep like so: sleep 2 That'll sleep for 2 seconds. Be careful to give an argument. If you just run

I want PHP to output some text, then sleep for a second and a half, and then output some more text. <?php echo 'Output one.'; usleep(1500000); echo 'Output two.'; ?> My problem is that all text is being put out simultaneously - after having waited those 1.5 seconds. I have read something about a function called flush - but it doesn't seem to work. Maybe I'm not using it write. Any help would be appreciated ^^ Thanks in advance! check this out <?php ob_start(); echo 'Output one.'; ob_flush(); usleep(1500000); echo 'Output two.'; ob_flush(); ?> Pentium10's answer did not quite work for me..

I'm using Timer from Timers namespace. What happens to timer when PC goes to sleep or hibernates? I have timer set to 6 hours delay. What will happen in those situations. 1) Timer starts at hour 0 and goes to sleep/hibernation immediately. Then PC wakes at hour 5. Will my timer fire after next 1 hour or after next 6 hours? 2) Timer starts at hour 0 and goes to sleep/hibernation immediately. Then PC wakes at hour 7. Will my timer fire as soon as PC wakes or will it "miss" that one time and fire in next 5 hours? Will it start counting till next event from time of PC waking or from previous
