Player Interact while holding a certain item, null pointer issue?

Im getting a severe error pop up in the console for this line of code. I tried adding a check for if the material was null but it ddnt seem to work. I also tryed adding else if material != flint_and_steel but it still didnt work.

What i tried.

Code:

if (event.getItem().getType() == Material.FLINT_AND_STEEL && event.getItem().getType() != null) {

 

Item itself is an object in java and can be null (such as when the player has nothing in their hand). What you should try is:

Code:

if ((event.getItem()  !=  Null) &&  (event.getItem().getType() == Material.FLINT_AND_STEEL){
//do something
}

This checks to see if the object is null and skips the event if it is. (Note: Order matters here. Java checks from the left to the right)

 

I'm just curious as to why you need a null check? If the item in their hand isn't flint and steel it wouldn't pass through, so I don't understand the null check

 

Thank you it works perfectly.

 

because if there is no item in their hand it event.getItem() will be null, so when they go to do event.getItem().getType() it will throw a null pointer exception

 

Oh crap ... Never thought about that .. I always just thought it would return it as air or something ... I think I should go do some null checking in a few of my plugins

 

air is considered null in the inventory, i went through that same situation working on ClearInv back in the beginning
