I’m trying to make a plugin that implements a beta 1.7.3 eating system. I have a Spigot version that works but I wanted to make it for Sponge. I’m having problems with checking the item type. Maybe I am just doing something wrong but I’m doing it how the tutorial says and I’ve tried googling it as well. Here is the code.
[code]public class PlayerInteractListener
{
@Listener
public void onPlayerInteraction(InteractBlockEvent.Secondary event, @Root Player player)
{
if (isBeef(player.getItemInHand().orElse(null)))
{
HealthData newHealth = player.getHealthData().set(Keys.HEALTH, player.get(Keys.HEALTH).get() + 1);
player.offer(newHealth);
}
}
public boolean isBeef(ItemStack stack)
{
ItemType type = stack.getItem();
return type.equals(ItemTypes.COOKED_BEEF);
}
}
[/code]
I left out the imports. Yes the listener is called in the main class and also working. However errors are being thrown at the type check.

Your plugin wouldn’t compile if you were using API 5.0.0 since the method simply doesn’t exist. Make sure your IDE dependencies are correctly pointing to an updated 5.0.0 snapshot build.
I figured it out. In Maven, I had copied the Maven code from the tutorial (I’ve never worked with Maven before) which had Sponge dependency as 4.1.0. I didn’t think that really mattered but apparently it does.
Now, what do you put for the two hands? It doesn’t autofill HandType.
read the stacktrace its says whats wrong
java.lang.NoSuchMethodError: org.spongepowered.api.entity.living.player.Player.getItemInHand()Ljava/util/Optional;
Method getItemInHand in the Player class which returns Optional is missing. Usually this happens when one or more java libraries are not up to date with application/sdk/…
Uh, no. It’s because getItemInHand takes a HandType in 5.0.0. This is a 4.1 plugin that they’re trying to run on 5.0. If it didn’t know what a class was, it’d say NoClassDefFoundError.
