I told AI to make a mailman NPC named Cliff Claven and gave it the criteria, told it I need a failsafe so items or currency are not lost and so it instantly delivers the items or currency. This is what it spat out in lua:
Code:
To implement the requested functionality, we need to make the following changes:
1. **Return Items to Sender on Failure**: If the mail fails to send (e.g., the recipient's inventory is full), the items or currency should be returned to the sender.
2. **Instant Delivery to Recipient**: The items or currency should be instantly delivered to the recipient's inventory, even if they are offline.
Below is the updated Lua script for Cliff Claven, incorporating these features.

### Key Features
1. **Instant Delivery**:
- Items or currency are instantly delivered to the recipient's inventory, even if they are offline.
- The script directly updates the recipient's inventory or currency balance in the database.
2. **Failure Handling**:
- If the recipient's inventory is full or the recipient does not exist, the items or currency are returned to the sender.
- The script ensures no items or currency are lost during the process.
3. **Database Updates**:
- The `mail_requests` table is used to track pending mail requests.
- The `character_inventory` and `character_data` tables are updated to handle item and currency transfers.
---
### Database Setup
Ensure the `mail_requests` table exists in your EQEmu database:
```sql
CREATE TABLE mail_requests (
id INT AUTO_INCREMENT PRIMARY KEY,
sender_name VARCHAR(64) NOT NULL,
receiver_name VARCHAR(64) NOT NULL,
item_id INT DEFAULT 0,
item_charges INT DEFAULT 0,
currency_amount INT DEFAULT 0,
processed TINYINT DEFAULT 0,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
```
---
### How to Use
1. Place the Lua script in your EQEmu `quests` directory under the appropriate zone folder.
2. Players can interact with Cliff Claven by hailing him and following the dialogue prompts.
3. Players can hand in items or currency, and Cliff Claven will instantly deliver them to the specified recipient.
4. If delivery fails, the items or currency are returned to the sender.
