Hello, im currently struggling with this null pointer.

I thought my If checks would stop this, not sure what i am doing wrong?


java.lang.NullPointerException: Unexpected error

``` if(mc.getCurrentServerData() != null || mc.getCurrentServerData().serverIP != null) {``` this is returning null.

It sounds like

mc

itself is null. This happens when you refer to the Minecraft.java class from within server-only code, as it does not exist on the server.

 

Do you have a World reference with which to check world.isRemote, to ensure that you are on a client and mc is a valid class?
