由 折月煮酒 提交于 2019-12-11 01:09:12
问题 ok, so my google-fu really kind of sucks and I was unable to find an answer, hopefully you folks can help me ^_^ ok, so what I thought would be a simple script is seemingly not communicating with its subprocess correctly, I'm running this line by line. I'm also using the mpg123 player, this is a Linux system (well, Raspberry Pi) from subprocess import Popen, PIPE, STDOUT p = Popen(["mpg123", "-C", "test.mp3"], stdout=PIPE, stdin=PIPE, stderr=STDOUT) #wait a few seconds to enter this, "q"

If I try the gphoto2 --capture-image-and-download in the terminal it takes less than 2 seconds. I'm working on a Raspberry Pi. Code: import subprocess class Wrapper(object): def __init__(self, subprocess): self._subprocess = subprocess def call(self,cmd): p = self._subprocess.Popen(cmd, shell=True, stdout=self._subprocess.PIPE,

How to communicate 'externally' between Adobe Animate CC animations?

由 橙三吉。 提交于 2019-12-07 20:50:26
问题 From the script in the html page, I'm trying to control what happens in the Adobe Animate CC animations I've created. For example, here you'll see a script that doesn't work that's trying to tell the ship animation to gotoAndPlay(5). Anyhow, the ship animation is not responding to that. I'm guessing it's because I'm not addressing/naming it correctly. Help me talk to my animations. See the code below. <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Lets talk to each other</title>
