This event is fired when a player left clicks while targeting a block. This event controls which of Block#attack(BlockState, Level, BlockPos, Player) and/or the item harvesting methods will be called.

Note that if the event is canceled and the player holds down left mouse, the event will continue to fire. This is due to how vanilla calls the left click handler methods.

Also note that creative mode directly breaks the block without running any other logic.

The event is cancelable.

If the event is canceled, none of the above noted methods to be called.

The event does not have a result.

Importing the class is recommended for events, simply add this line to the top of your script file.

ZenScript
 Copy
import crafttweaker.neoforge.api.event.interact.LeftClickEmptyEvent;

ZenScript
 Copy
events.register<crafttweaker.neoforge.api.event.interact.LeftClickEmptyEvent>(event => {
    println("LeftClickEmptyEvent ran!");
});

LeftClickEmptyEvent extends PlayerInteractEvent. That means all methods available in PlayerInteractEvent are also available in LeftClickEmptyEvent
