Changing player object UNET

Hello, people

I’m making a little game where players can change what object they’re cotrolling. Like they start with a ball and they can roll it using WASD, and when they collide with some other ball tagged “PlayerBody”, they will have control on that ball and lose it on old one.

Here’s what I do (PlayerBodyScript.cs inheriting from NetworkBehaviour):

private void OnCollisionEnter(Collision col) {
		if (tag == "Player") {
			// ... some code about jump landing

			if (col.gameObject.tag == "PlayerBody" && plyLastUpdated + 3f < Time.time){
				// set new body if collided with PlayerBody
				col.gameObject.GetComponent<PlayerBodyScript>().color = color;

				if (isLocalPlayer){
					// local player updates the camera
					col.gameObject.GetComponent<PlayerBodyScript>().cam = GameObject.Find("Main Camera").transform;
					GameObject.Find("Main Camera").GetComponent<CameraScript>().UpdateTarget(col.gameObject);

				if (isServer) NetworkServer.ReplacePlayerForConnection(connectionToClient, col.gameObject, playerControllerId);

				// unsetting player from this object

				color = Color.white;

				plyLastUpdated = Time.time;

But every time I touch other PlayerBody I got this error and user takes control over both bodies (I do not want to destroy old one, but just “move” user to the other “body”):

The error

I am wondering what I’m doing wrong? I’m kinda new in UNET and Unity overall.
Thank you for any help.

As i can see: ReplacePlayerForConnection don’t actually “replace” player controled object but adds new object to control.

So you need to use ReplacePlayerForConnection to your old object too.

PS: Could be wrong, i’ll check it myself.
