any way to reset an entity
Could you elaborate a little on what you mean by resetting an entity? It is difficult for other members of the forum to provide assistance without sufficient information.
Try to keep these questions in mind when making a post as it makes it easier for others to help you:
What behavior am I trying to code? What code have I tried in order to implement this behavior? (Include this code for others to help) What behavior is my project exhibiting now? What (if any) errors is my project generating? How might others get to my project? Why do I think the code I have used is not working? (Mostly optional, but can help with troubleshooting on your own)
