i've created a little script that will be started on several computers. The script will start by opening an image, on the computer, and then it will have to be paused for some time. and at the same time. all of the computers should continue the script.
The way i found out this could work, is to set the computer to ask if(text from textfile on server) is true or false. if false then it will ask again. (creating a loop). when i change the text file to true and save it. it will continue in the script.
Is this possible and how stressing is it for the computer to look in the file every second? or any other ideas how i could do this without having access to the computer?
