Inventory Weights Items Configuration

The ItemWeightConfigItems class is designed to manage and store custom item weight configurations for the MT Inventory Weight mod. It works by reading from and writing to the inventory_weights_items.json file, which contains item-specific weight data.

Configuration Options

The inventory_weights_items.json file holds the custom item weights specified by players or mod authors. This allows for precise control over the weights assigned to specific items, providing flexibility in how the weight system affects gameplay.

Key Methods

• loadConfig():

  • This method checks for the existence of the inventory_weights_items.json file.
  • If the file exists, it reads the file and loads custom item weights using ItemWeights.loadCustomWeightsFromConfig().
  • If the file does not exist, it creates a default configuration and saves it, then loads the default values into the mod.

• saveConfig():

  • This method writes the custom item weights to the inventory_weights_items.json file.
  • It filters out static or default item weights, saving only dynamically configured weights from the player's modifications.
  • The ItemWeights.getCustomItemWeights() method is used to retrieve the custom weights before saving.

File Structure

The inventory_weights_items.json file contains custom weights in the following format:

{
    "minecraft:stone": 810.0
}

In this example, minecraft:stone is assigned a weight of 810.0f. You can add or modify items and their respective weights in this file.

Custom Weight Management

• createDefaultConfig():

  • This method creates a default configuration with preset weights for known items. It currently assigns a weight of 810.0f to minecraft:stone.
  • You can modify or expand this default list to include more items as needed.

• isDynamicItem(String itemName):

  • This method checks whether a given item is dynamic (i.e., customizable by the player) and returns true if it can be modified.
  • Static items that are predefined cannot be modified and are filtered out when saving the configuration.

Error Handling

In case of an error while reading or writing to the inventory_weights_items.json file, exceptions are caught and printed to the console for debugging purposes. This ensures that the mod does not crash if something goes wrong during file handling.

Usage Example

To add a custom weight to an item, simply open the inventory_weights_items.json file in the config/inventoryweight directory and add the item ID along with its desired weight. For example:

{     
    "minecraft:iron_ingot": 100.0,
    "minecraft:diamond": 200.0 
}

After saving the file, the mod will load these weights the next time it runs.

Default Item Weights

The createDefaultConfig() method can be modified to include default weights for additional items. By default, only minecraft:stone is assigned a weight, but you can extend this list based on the items in your modpack or world.

Extending the Configuration

The configuration system is flexible and can be easily extended by adding more items and their corresponding weights to the inventory_weights_items.json file. Custom weights allow players to tailor the game’s weight system to their preferences, giving them control over how certain items impact movement and gameplay.
