Packets or entity data?

[Tryhard]

Hello, I'm trying to make a new turret entity. The entity itself is already done and into the game (with geckolib). Now i need to pass data from the model to the AI (client to server, for aiming purposes) I'm trying to understand packets, but i don't see how i can send data from the entity's model all the way to the goal it's going to use. Any ideas? Is there a better tool for this other than packets? should i look into entity data instead?

You must use entity data because entity data will be sent to the client to update the model.

E.G. The part of the turret you want to aim would be set as the head and you can use vanilla entity head rotation mechanics to determine what direction to aim. (Hopefully this is understandable and not a jumbled confusing mess.)

I made some progress with entity data. I've managed to get the rotation from the bone into EntityDataAccessor fields in the entity class. But now they are not  synched to the server. So i need to mark them as dirty? or are they supposed to synch automatically?

Got entity data to work, thanks!
