/*

The PlayerInteractEvent has different types of action.

In particular, RIGHT_CLICK_BLOCK and RIGHT_CLICK_AIR can be called 2 times,

as there's the click with the main hand and the click with the secondary hand.

You therefore need to specify which hand you want to use like as follows:

*/

​

@EventHandler

public void onPlayerClickWithStick(PlayerInteractEvent event) {

    EquipmentSlot e = event.getHand();

    // Exclude secondary hand

    if (!e.equals(EquipmentSlot.OFF_HAND)) return;

    // Your code here ...

}
