问题 Below is the code I am currently running. I am trying to make a text based version of the arcade game Tron. I want the game to run automatically unless the user enters a direction (WASD). I have looked into timers and I know that if I were to use swing I could implement action listeners but this project is to be done strictly without a GUI. I was wondering if anyone might have some ideas how to make the game more dynamic and not turn based. while (player1.playerAlive) { String directionPrompt

问题 I know this is a simple problem and I could just use the time function or something, but it's somehow still a problem to me. So I have this: letter = pygame.image.load('w00.png') screen.blit(letter, (letter_x, 625)) letter_x += 30 letter = pygame.image.load('e-2.png') screen.blit(letter, (letter_x, 625)) letter_x += 30 letter = pygame.image.load('l-2.png') screen.blit(letter, (letter_x, 625)) letter_x += 30 letter = pygame.image.load('c-2.png') screen.blit(letter, (letter_x, 625)) letter_x +=

问题 I have a data set with a character column for months ( MONTH ) and a numeric column indicating years ( YEAR ). In order to work with it as panel data, I need to unite these YEAR and MONTH into a variable with a date format. I have tried to change the variable MONTH to numeric format and then to merge MONTH with the column YEAR . R would not recognize it as a date variable.

问题 So i am trying to 'animate' my character in pygame by changing between 2 pictures when he walks. I tried to use the code that was mentioned here: In PyGame, how to move an image every 3 seconds without using the sleep function? but it didn't turn out too well. In fact my character only uses one image when walking. here the part of the code and some variables: self.xchange: change on x axis self.img: image for when the character stands still self.walk1 and self.walk2: the two images i am

问题 How can I convert the annoying 12h time format (with AM and PM) into the 24h time format? I wanted to avoid external programs like awk as in this example. Since gnuplot has a time-specifier %p for "am" and "pm" (check help time_specifiers ), I thought it would be easy. But the following code does not give the correct result, but a warning message: warning: Bad time format in string Maybe, I'm using %p incorrectly? Code: ### change 12h time format to 24h format (does not give correct results)

问题 I am new to javascript and am trying to compare two date values ,I am getting two time value strings in the format 06:30:47 AM 01:10:47 PM I need to compare these to find out if the first one is less than the other.I couldn't figure out how to do this in javascript.Can someone help? o.h 回答1: I do not think that the standard implementation can parse this.
