CustomGive

1. Command Arguments Added:

   • The customgive command now accepts two arguments:
     • block_or_item: Expects a string representing the block or item name.
     • amount: Expects an integer representing the amount of the custom item to give.
   • This change allows for more flexibility in specifying the custom item and its quantity.

2. Item Mapping Method Added:

   • Added getItemByName method to map item names (block_or_item) to their respective Item instances.
   • This method takes the lowercase item name as input and returns the corresponding Item object.
   • The mapping includes several default items like "stone," "diamond," "iron_ingot," and others.

3. Usage of Block/Item Name and Amount:

   • The giveCustomItemFromClipboard method now takes blockOrItem and amount parameters to determine which item to create and how many to give.

4. Error Message Update:

   • In case of invalid NBT data or an unrecognized block/item name, the error message has been updated to "Invalid NBT data or block/item name."

5. ItemStack Amount:

   • The createItemStackFromNBT method now sets the amount of the ItemStack based on the amount parameter passed to it.

6. Expanded Item Mapping:

   • The getItemByName method includes a switch-case block that covers a variety of common items. You can extend this mapping as needed to support more items.

These changes enhance the functionality and configurability of the customgive command, making it more versatile for giving custom items in the game.
