useOnBlock

public ActionResult useOnBlock(ItemUsageContext context)

Called when an item is used on a block.

This method is called on both the logical client and logical server, so take caution when using this method. The logical side can be checked using context.getWorld().isClient().

Overrides:

useOnBlock in class Item

Parameters:

context - the usage context

Returns:

an action result that specifies if using the item on a block was successful.

use

public TypedActionResult<ItemStack> use(World world,
 PlayerEntity user,
 Hand hand)

Called when the player uses (or starts using) the item. The use action, by default, is bound to the right mouse button. This method checks the player's hunger when the item is a food, and will pass in all other cases by default.

If the item can be used for multiple ticks, then this will only be called when the player starts using it. After that, Item.usageTick(net.minecraft.world.World, net.minecraft.entity.LivingEntity, net.minecraft.item.ItemStack, int) is called every tick until the player finishes using the item.

This method is called on both the logical client and logical server, so take caution when overriding this method. The logical side can be checked using world.isClient().

Overrides:

use in class Item

Parameters:

world - the world the item was used in

user - the player who used the item

hand - the hand used

Returns:

a typed action result that specifies whether using the item was successful. The action result contains the new item stack that the player's hand will be set to.
