Help with character stuck on character screen screen

[crayonfite]

Hello,

After I have clicked on my character to go into game, after entering the pic, the character runs and nothing happens. I checked my log and it gives this

java.lang.NullPointerException	at tools.packet.PacketHelper.addInnerStats(PacketHelper.java:700)
	at tools.packet.PacketHelper.addCharacterInfo(PacketHelper.java:679)

addInnerStats line 700 is mplew.writeShort(Skills.size());

Any help would be appreciated :) server is 117.2 and source has a moderate amount of judoms files.

Nevermind! I solved it myself :) only a temporary fix until i find a solution for this though.. If anyone would like to explain what happened there to me it'll also be appreciated, if not the thread can be closed.

Knowing how to read the exception is a good start.

Now you have to know what the exception is caused from. It says it's a NullPointerException, which means something is being dereferenced that doesn't exist. This is like:
Object o = null; // new object
o.toString(); // this will give an exception because o is "null" and you are trying to call toString for something that "doesn't exist"

So basically in this case skills is probably null. Skills looks like it's a list of some sort. Make sure the list is initialized and that the inner abilities have been added.

I see! Thanks for the explanation :)
