    ==================== TUTORIAL FOR IMPLEMENTATION ====================
    This guide explains how to implement the ShowWeapon script and integrate it with 
    the ThirdPersonCharacter script for a smooth weapon-switching experience.

    1. **Purpose:**
       - Toggles the visibility of two weapons or items based on player input.

    2. **Setup:**
       - Attach this script to the character GameObject that already has the ThirdPersonCharacter script.
       - Assign `item1` and `item2` to the weapon or item GameObjects in the Unity Inspector.

    3. **Default Controls:**
       - Press `1` to show item 1 and hide item 2.
       - Press `2` to show item 2 and hide item 1.
       - Press `R` to hide both items.

    4. **Integration with ThirdPersonCharacter:**
       - Ensure that `item1` and `item2` are parented to appropriate bones of the character model (e.g., hand bones).
       - This will ensure the weapons follow the character's movement and animations.
       - If you want the `ThirdPersonCharacter` script to react to the equipped weapon, you can:
         - Add references to `item1` and `item2` in the ThirdPersonCharacter script.
         - Modify the script to check which weapon is currently active.

    5. **Testing:**
       - Assign two weapon models to `item1` and `item2` in the Inspector.
       - Ensure both weapons are properly positioned and aligned with the character's hands.
       - Play the scene and switch weapons using the assigned keys (1, 2, and R).

    6. **Customization:**
       - Modify the keys for weapon switching in the `Input.GetKeyDown` checks.
       - Add additional weapons by expanding the script to include more items.
       - Integrate animations for equipping and unequipping weapons.

    7. **Advanced Enhancements:**
       - Implement weapon-specific actions in conjunction with the ThirdPersonCharacter script (e.g., shooting, melee attacks).
       - Add UI elements to visually indicate the currently equipped weapon.
       - Include sounds or visual effects when switching weapons.
