同步捕获屏幕截图

Question

i am writing screen capture in my Unity3D program. with this method:

Application.Capturescreenshot("fileName.txt");

it works well and it saved to the project root folder. now i want to move it to another path so i am checking if the file exist line after i am taking the capture, and it turns out that in the next line the capture did not saved yet. it probably happens asynchronous. i want this line to be executed synchronous.

what would be the easiest solution?

Answer 1

If the CaptureScreenshot API doesn't give you a way to either do it synchronously or execute a delegate when the file has been saved, then you have two options:

1. Continuously poll to see if the file has been created (flaky, I wouldn't do this), or
2. Use a FileSystemWatcher to watch the folder for changes. You can give the watcher a delegate that will be executed whenever a file is added to the folder, and you can use the delegate to move the file.
