Stop items being destroyed when struck by lightning

I was thinking about doing something usng ItemDespawnEvent and doing if (event.getCause() == lightning) event.getCancelled(true); but there is no getCause() for this event. Would anyone know a different method or way of doing this?

 

@SiezureSalad
Use an event relevant to the entity being damaged. This way, you can check the cause and also have access to keep the items.

 

@SiezureSalad
From the spigot docs:

You need to use EntityDamageEvent instead to check if an item was hit by lightning.

 

Thanks but now I am getting this error when starting the server:

Your jar is most likely corrupted. Try recreating/re-exporting the plugin.

 

And it also cancels damage for every entity if the cause is lightning. Check if event.getDamaged() (or .getEntity(), don't know the exact name atm) is an Item

 

I recreated the whole thing in a new project and re-exported it and I get the same result.

Okay I fixed it by changing the name of the classes. It must have had a problem with them or something.

@Zombie_Striker @FisheyLP the lightning works fine however the items get destroyed from the lightning still. (the code is unchanged from my last post)

 

@SiezureSalad
Have you debugged? Does the event get triggered for Items? Are you also checking if the items are being burned (since lightning causes fire)

 

I have another plugin that disables fire from lightning.
I think this is the wrong event to be using. My other plugin also causes lightning so I used it to test where debugging got to when I threw an item in creative mode and it didn't log anything. When I attacked a squid it registered "Entity was damage.". When the squid was struck by lightning it registered to "Cause was lightning." so I think this is the wrong event.

@Zombie_Striker Any other events you would recommend?

 

Directly from the JavaDocs, Theres an event Called EntityCombustByEntityEvent & EntityCombustEvent. These are called when a live entity is set on fire. Iv'e never tried it on an item. Why don't you try these?

 

There is no getCause() only getCombuster() which is an entity. I don't think lightning is an entity so I can't make this work.

In the end I just set the lightning strike to be 5 blocks higher than the player that died so the items don't get destroyed. Thanks for your help anyway.

 

@SiezureSalad
I think Lightning is an entity:
