Ok, I also already thought of limit lasers and the battle ground normally avoids it that a laser beam can really get infinit. So let’s say I would do it inside a visible zone, I could then do that by pass similar to SimplePhysicsSystem, right? Doing it via Zone updates and a body position publisher (I didn’t yet got the idea of that body position publisher tbh, but I think it is for the server side part).
I fear if I’m not doing nearly the same as the ship I will look jumpy or strange. Ok the visual part I could do by just know which laser beam follows which ship on the client, but it still can lead to strange things, like get damage from a laser which is visual not where you are and so on.
The good part now is, afterwards I also understand that part of your example
EDIT: For interpolation, what kind of math do you use for that? I found in the math for dummy a linear interpolation, maybe enough, but for rotation? I mean JME maths
