If anyone is like me and you hate seeing all the debug issues, even if they do not cause any problems one issue you’ll get on this in the _process function it is upset that you are getting a delta but you are not using it anywhere in your function. This causes debug to want you to fix it. You can just change this to _delta instead and it will no longer give you a debug error.
Then if you do want to pass in Delta later you can always just remove that _ again.
