math quiz with a time limit (simultaneous functions) - advanced python

由 穿精又带淫゛_ 提交于 2019-12-23 02:32:12
问题 So I would like to run two programs, a timer and a math question. But always the input seems to be stopping the timer funtion or not even run at all. Is there any ways for it to get around that? I'll keep the example simple. import time start_time = time.time() timer=0 correct = answer answer = input("9 + 9 = ") #technically a math question here #so here until i enter the input prevents computer reading the code while True: timer = time.time() - start_time if timer > 3: #3 seconds is the

NSTimer: floating point value can not be converted to UInt8 because it is greater than UInt8.max

由 ≯℡__Kan透↙ 提交于 2019-12-23 01:45:11
问题 My code returns the error: fatal error: floating point value can not be converted to UInt8 because it is greater than UInt8.max. The code is being called when a button is pressed (in a different swift file) but I know that the problem wasn't with calling the function so I didn't include it. code: //starts the timer func startTimer(sender: AnyObject) { if !timer.valid { timer = NSTimer.scheduledTimerWithTimeInterval(0.01, target: sender, selector: Selector(updateTime()), userInfo: nil, repeats

C# using a timer inside a Backgroundworker

由 假装没事ソ 提交于 2019-12-22 18:57:20
问题 I couldn't find a solution for this yet...hope someone can help me. I have a backgroundworker that runs until it is cancelled by the user (it reads data from a socket and writes it into a file). Now I want to split the output file after a certain period of time, e.g. every 2 mins create a new file. For this to happen I'd like to use a timer, something like private void bckWrkSocket_DoWork(object sender, DoWorkEventArgs e) { //create timer and set its interval to e.Argument //start timer while

Simulating movement similar to dust particles

由 回眸只為那壹抹淺笑 提交于 2019-12-22 18:43:00
问题 I've tried a setInterval loop with css and animate. Both ways of movement consists of tiny movement from oldpos1 -> newpos1 with no random curve movement, easing however occured with jQuery animate but only between randomly generated 1-3 pixels, which is not what I want . Does the problem lies in setInterval 's clock, where only linear time units flow? Where should I start, to make below images exist in jQuery? What I would like to do: Dodge behaviour: A, B - particle AB1 - common dodge area,

由 折月煮酒 提交于 2019-12-22 14:04:13
问题 I am creating an image slideshow in ruby, using gtk pixbuf to load images. I am very new to ruby & GTK, this may be an stupid question. Currently image changes are linked to the GUI button_press_event, I would like them to change /refresh automatically based on a set time, like a slideshow or animation. I saw the gtk animation using a gif method, but I would like to use individual jpeg files inline sequence, so that I can set the time to show a slide. Once the loop has gone through all the

问题 I want to draw a disc that changes colors twice a second. The disk is drawn on a DrawPanel which extends a JPanel and in the main method the DrawPanel is added to a frame.

Can someone tell me why it doesn't work for the Graphics g object or any other suggestions? I just copied the code from the main method and added it into the paintComponent()

问题 This question is done (and solved) before, see Outlook VBA - Run a code every half an hour I used the code fore several years on with no trouble on several computers running Vista (32 bit), Windows 7 and Windows 8.1 (all 64 bit).
