Change the postion of GameObject

Unity Engine
1

Hi,

I’d like to change the position of GameObject as

getting x, y, z from my server.

Generally this function works correctly,

but this function often makes a crash at this point.

obj.transform.position = pos;

I checked all data from server is not wrong.

Can anyone tell me what the problem of this function is?

	public void S2CMove(byte[] packet, int index)
	{
		if(packet==null)
		{
		}
		int uniqueID = BitConverter.ToInt32(packet, index + 4);
		float x = BitConverter.ToSingle(packet, index + 8);
		float y = BitConverter.ToSingle(packet, index + 12);
		float z = BitConverter.ToSingle(packet, index + 16);
		
		string objName = "id" + uniqueID;
		
		GameObject obj = GameObject.Find(objName);
		if(obj==null)
		{
			return;
		}
		Vector3 pos = new Vector3(x, y, z);
		obj.transform.position = pos;
			}

Your i(packet==null) test doesn’t do anything as you just open then close brackets, then continue on, even if packet IS null.

Something like this would work better…

public void S2CMove(byte[] packet, int index) { 
      if(packet!=null)  { 

           int uniqueID = BitConverter.ToInt32(packet, index + 4); 
           float x = BitConverter.ToSingle(packet, index + 8); 
           float y = BitConverter.ToSingle(packet, index + 12); 
           float z = BitConverter.ToSingle(packet, index + 16); 
       
           string objName = "id" + uniqueID; 
       
           GameObject obj = GameObject.Find(objName); 
           if(obj!=null) { 
 
                Vector3 pos = new Vector3(x, y, z); 
                obj.transform.position = pos;
          }
     }
}
