In the world of game development, creating a dynamic and engaging trading system is crucial for player interaction and immersion. A modular trader system that utilizes JSON configurations can provide a high degree of flexibility and customization. In this step, we will delve into the process of defining trade behaviors using JSON configurations for NPCs (Non-Player Characters).

🛠 Sub-Steps:

1. Define Trade Behavior in JSON

Defining trade behavior in JSON is a crucial step in creating a modular trader system. This involves associating TRADE IDs with specific loot pools, implementing refresh timers, and allowing different trade types. By using JSON configurations, you can easily modify and update trade behaviors without requiring extensive coding changes.

Associating TRADE IDs with Specific Loot Pools

When defining trade behavior in JSON, it's essential to associate TRADE IDs with specific loot pools. This allows you to control which items are available for trade and ensures that the trade system remains balanced and engaging. For example, you can create a JSON configuration that associates a TRADE ID with a loot pool containing rare items.

{
  "TRADE_ID": {
    "loot_pool": [
      {
        "item_id": "rare_item_1",
        "quantity": 1
      },
      {
        "item_id": "rare_item_2",
        "quantity": 1
      }
    ]
  }
}

Implementing Refresh Timers

Implementing refresh timers is another critical aspect of defining trade behavior in JSON. This allows you to control how often trade items are replenished and ensures that the trade system remains dynamic and engaging. For example, you can create a JSON configuration that reloads trade items every 24 hours.

{
  "TRADE_ID": {
    "refresh_timer": {
      "interval": 86400, // 24 hours in seconds
      "type": "rotating" // replace oldest item
    }
  }
}

Allowing Different Trade Types

Finally, allowing different trade types is essential for creating a modular trader system. This enables you to control how trade items are replenished and ensures that the trade system remains balanced and engaging. For example, you can create a JSON configuration that allows only X trades per 24 hours.

{
  "TRADE_ID": {
    "trade_type": "limited",
    "max_trades": 5,
    "interval": 86400 // 24 hours in seconds
  }
}

2. Implement Player-Specific vs. Server-Wide Trade Tracking

Implementing player-specific vs. server-wide trade tracking is a critical aspect of creating a modular trader system. This allows you to control how trade items are tracked and ensures that the trade system remains balanced and engaging.

Player-Specific Mode

In player-specific mode, each TRADE ID stores a list of players who have bought it. If a player has used the trade, it becomes unavailable only for them. This ensures that players cannot exploit the trade system by repeatedly using the same trade.

{
  "TRADE_ID": {
    "player_specific": true,
    "players": [
      {
        "player_id": "player_1",
        "used": true
      },
      {
        "player_id": "player_2",
        "used": false
      }
    ]
  }
}

Server-Wide Mode

In server-wide mode, when a trade is completed, it becomes unavailable for everyone. This ensures that the trade system remains balanced and engaging, and prevents players from exploiting the system by repeatedly using the same trade.

{
  "TRADE_ID": {
    "server_wide": true,
    "available": false
  }
}

3. Develop JSON Loader & Trade Handler

Developing a JSON loader and trade handler is a critical aspect of creating a modular trader system. This involves reading trade rules from JSON and applying them dynamically, ensuring correct data synchronization between NPCs and the trade system.

Reading Trade Rules from JSON

The JSON loader is responsible for reading trade rules from JSON and applying them dynamically. This involves parsing the JSON configuration and updating the trade system accordingly.

{
  "TRADE_ID": {
    "loot_pool": [
      {
        "item_id": "rare_item_1",
        "quantity": 1
      },
      {
        "item_id": "rare_item_2",
        "quantity": 1
      }
    ]
  }
}

Applying Trade Rules Dynamically

The trade handler is responsible for applying trade rules dynamically. This involves updating the trade system based on the JSON configuration and ensuring correct data synchronization between NPCs and the trade system.

void apply_trade_rules(const char* trade_id, const char* loot_pool) {
  // Update trade system based on JSON configuration
  // Ensure correct data synchronization between NPCs and trade system
}
