Another add:
If I made this I would just have the server door check everyone’s range all the time and have that loop running always. I don’t know why you’re relying on the player to tell the server it’s within range. I’m assuming you’re using some sort of custom implementation for it, but if it was me I’d either just use the same algorithm to check the distance and direction, or I’d just use ZonePlus with a detector in front of the door if more precision is necessary. Performance is usually negligible for something like this anyway, you should only worry about that if you actually notice it in game. Just my extra two cents.
