What do you mean by "update" and by "region"?
Also are you talking about the core mobile.cs?
Oh, sorry, my English is not very good. This involves my packet, I would like to know which one is to be sent to players other players exist within the screen of the packet. In other words, the screen update packet inside.
Do you know which method has the effect of it?
I changed Server/Mobile.cs
public virtual bool Move (Direction d)
Some of the code to achieve some results, but only when the player moves will be effective.
Standing still, the code will lose effect.
