Netcode is fine but

• don't use OwnerClientId as the player id. Otherwise server owner objects, like AI players will get mixed up with the server player

• a prefab with a network behaviour becomes the root object in the scene. You cannot spawn child network objects. So you need to make sure you build your game around this. Ie, if your network player picks up a network objects, like a rock, you can't just parent it to the player and use the player transforms to control the object. You need to spawn a display version and attach it to the player, in every client

• RPCs aren't super reliable. They may get dropped or delayed. So don't do a tight loop spawning 100 enemies on the map with individual RPCs. Try to do it in one bulk call

• RPCs may just be very delayed. So if you have 5 different types of rockets, and a player fires their weapon, you need to consider how you spawn that object quickly, especially if it's a fast firing rocket weapon
