unity3d - Efficient way to check where the bullet came from player [Unity Multiplayer Mirror]

Question

I'm new to mirror so bare with me. What I'm trying to do is when a player gets hit by the bullet of another player it can check whose bullet came from my option is:

1.) add player tag to bullet 

or there is a better way using mirror

Answer 1

1. Attach Network Identity to root of bullet to ensure it spawns on other clients.
2. Create a NetworkBehaviuor script to manage any logic or data associated with the bullet.
3. Add a single int firingPlayerId; field with the [SyncVar] attribute to the script.
4. Update this variable whenever a player uses this object as a bullet to shoot (assuming you have some kind of caching going on, you'd need to change this).

Since NetworkIdentity makes sure variables are only synced when they are modified/dirtied, this won't cost you anything.
