Hello! What I want to do is learn about networkownership and the different properties in it. Can you help? I have tried looking on youtube but no luck.
YouTube probably isn’t the place to look for documentation. Network Ownership | Roblox Creator Documentation
Still can’t seem to understand it, 
Network Ownership decides who controls the physics of a part.
If the ownership of a part is set to nil, then the server simulates the physics for it. If it’s set to a Player then that specific Player simulates the physics for that specific part.
If you didn’t set any ownership thru BasePart:SetNetworkOwner() then the engine is gonna decide who should control a part.
If there’s a client close to a part then the client owns it. If not, the server owns it.
If there’s multiple clients near a part then the engine will decide who out of all clients near it should own it.
