Unet: From playerobject spawned Objects scripts not working

Hey everyone!
I followed some tutorials about Unity Networking and made a PlayerObject that spawns right at connecting… it only has one job … to let me select from a list of different Vehicles and then spawn them …

My Question ist how i make the Scripts connected to the Spawned Vehicles locally executable …
i use if (!isLocalPlayer) { return; } but its not working even if i spawn with client authority…

I hope youre able to understand what im trying to say
Please excuse my pritty bad english

I’m thankfull for every helping word i can get,

that’s because the player object is the one and only object which may ask for isLocalPlayer. all other spawned objects need to use hasAuthority to distinguish themselves from other clients besides the “so to say local player”.
