1.12 Creating a Heal Event

[Justin_Perry]

Hello, I have been trying to create a healing event that heals living entities when right-clicked with a certain item. However, when the character right clicks with the item, nothing occurs, that I can see.

package Justin_Perry.learningMod.EventHandlers;


import Justin_Perry.learningMod.init.modItems;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.network.play.server.SPacketCombatEvent.Event;

public class MedicEvents 
{
	
	public boolean onRightClickHeal(ItemStack itemStack, EntityPlayer player, EntityLivingBase target)
	{
		 if (player.getHeldItemMainhand().getItem() == modItems.FAIRY_DUST && target.getHealth() < target.getMaxHealth()) {
			 System.out.println(target.getHealth());
			 target.setHealth(target.getHealth() + 2.0F);
			 System.out.println(target.getHealth());
			 
			 return true;
			 
		 }else {
			 return false;
		 }
	}
}

Thank you for your time today.

Which event are you using for your function?

[DavidM]

There is no need for events.

Override Item#itemInteractionForEntity in the class of the item you want to use to heal (get the target (EntityLivingBase) from the parameters ).

 

Apart from that, the code you posted is not a valid event subscriber. Event subscribers take in exactly one parameter (event type).

Yeah, but that only works for new Items

[DavidM]

If the behavior is to be implemented with a new item, prioritize overriding Item#itemInteractionForEntity over creating an event subscriber.

 

If for some reason the "overriding Item#itemInteractionForEntity" cannot be implemented, create an event subscriber for PlayerInteractEvent.EntityInteract.
