Re: java.lang.NullPointerException in mmo example unity

Postby Lapo » 26 Oct 2022, 16:05

Hi,
the example is supposed to work out of the box, having followed the tutorial setup.
http://docs2x.smartfoxserver.com/Exampl ... mmo-basics

The exception indicates that the Extension cannot read some of the basic properties of the MMORoom.
Can you take another look at the "Setup and Run" section of the tutorial and double check each step?

Thanks
Lapo

It sounds like you have installed the example correctly and then made changes that broke the client code.
However it is quite difficult to guess what you might have changed and you didn't provide enough details as to what these changes might be.

My suggestion is to restart from scratch, reinstalling a fresh copy of the Example.

on admin tool side i create a room MMOBasics room here room extension is disable.

There is no need for this. If you check our documentation we don't say to manually create any Room.
Also in one of your screenshots you're showing the "Lobby" Room with attached the example Extension. Again... this is not what the doc says to do, and it will cause problems because the "Lobby" Room is not an MMORoom.

Please stick to the documentation.

Thanks
Lapo
