DirectoryWatcher will notify you whenever files or file list has changed in a directory.
- Create the watcher.
var watcher = DirectoryWatcher.new()
add_child(watcher)- Add a directory to watch.
watcher.add_scan_directory("res://directory")(automatically gets converted to absolute path; you can add more than 1)
- Connect signals.
watcher.connect("files_created", self, "on_files_created")
watcher.connect("files_modified", self, "on_files_modified")
watcher.connect("files_deleted", self, "on_files_deleted")- Enjoy.
DirectoryWatcher will periodically crawl over the files in a directory and report all file changes. Sub-directories are ignored and the scan isn't recursive. To reduce I/O operations, the scan runs every second and scans 50 files per frame inside _process() method. Rate of scan and files per frame are configurable with scan_delay and scan_step variables.
watcher.scan_delay = 0.5
watcher.scan_step = 20
The signals are emitted at the end of a scan cycle and files are passed as absolute paths.
You can deregister a directory by using remove_scan_directory(). This will take effect at the end of next scan cycle.
