Been a few months since I last made a comment, and after trying to figure out how to use it on and off the whole time, I can say this: If you want to buy this, don't. Dev has seemingly abandoned the plugin with no answers in over a year. They may have abandoned the account all together, since there doesn't seem to be any new activity on their other projects either. Their YouTube and WordPress are just as quiet.
The pathfinding also doesn't always work consistently, since I still sometimes get the x undefined error, and trying to use the plugin commands to make it work are also hit-and-miss. What bothers me most in attempting to use it is there's no wait function, and sometimes other commands in the event will run before the pathing, even if the pathing is the first command in the event. This happens regardless of using the scriptcall or plugin.
TLDR eyebleeding font: Don't spend 5 bucks on this, not worth it.
