my consol error

did you check if the item in your hand is not null, has itemmeta? in you code thats a no. because you want to get the item meta of an item that doesn't have one it gives the null pointer on line 20

 

so you are saying that i should do something like this on line 20?

if(hand!=null && hand.getItemMeta().getDisplayName().equalsIgnoreCase("AreaSelecter")){

sorry i'm new and don't get it. because this will also give the error

 

@cfritten getDisplayName() may also return null

 

so you say that i need to check if the getDisplayName() give null?

like:
if(hand!=null && hand.getItemMeta().getDisplayName()!=null &&hand.getItemMeta().getDisplayName().equalsIgnoreCase("AreaSelecter")){

thats will still give the issue/error. my plugin work for they things i want it to do but then you play normal and hit some block it give the error. i know is it in my code but there in my code the issue is i can't see

 

@cfritten #hasItemMeta #hasDisplayName

 

thanks alot guys xD it works now!
