The PlayerDeathDrops Event is fired whenever a player's items fall to the ground due to the player's death.

You will need to cast the event in the function header as this class:
crafttweaker.event.PlayerDeathDropsEvent
You can, of course, also import the class before and use that name then.

PlayerDeathDrops Events implement the following interfaces and are able to call all of their methods/getters/setters as well:

• IPlayerEvent

The following information can be retrieved from the event:

ZenGetter	Return Type
ZenGetter player	Return Type IPlayer
ZenGetter items	Return Type List<IEntityItem>
ZenGetter damageSource	Return Type IDamageSource

You can either add to the droplist or completely substitute it with a new one:

ZenScript
 Copy
event.items = //reference to IEntityItem list.

//event.addItem(IItemStack item);
event.addItem(<minecraft:iron_ingot>);

//event.addItem(IEntityItem iten);
event.addItem(<minecraft:iron_ingot>.createEntityItem(event.player.world, event.player.position));
