Auto Collect Item Interaction Function in Lua

This document details a Lua function designed for automatically collecting items in a game. The function utilizes macro or mprecord capabilities to interact with items in a specified area.

Overview

The function autoCollectItems continuously checks for collectible items in the vicinity of the player and interacts with them when found. This implementation demonstrates best practices including input validation, comprehensive documentation, and use of comments for clarity.

Function Definition

Code

-- Import necessary libraries
local player = require("playerAPI")  -- Hypothetical API for player interactions
local itemAPI = require("itemAPI")    -- Hypothetical API for item interactions
local timer = require("timer")         -- Hypothetical API for timer management

---
-- Automatically collects items nearby every specified interval.
-- @param collectRadius number: The radius within which to search for items.
-- @param collectInterval number: The time interval (in seconds) to check for items.
-- @return nil
-- @throws error if collectRadius or collectInterval are not positive numbers.
function autoCollectItems(collectRadius, collectInterval)
    -- Input validation
    if type(collectRadius) ~= "number" or collectRadius <= 0 then
        error("collectRadius must be a positive number")
    end
    if type(collectInterval) ~= "number" or collectInterval <= 0 then
        error("collectInterval must be a positive number")
    end

    -- Function to check for collectible items and interact with them
    local function collectItems()
        -- Get player's current position
        local playerPosition = player.getPosition()

        -- Fetch nearby items within the collectRadius
        local items = itemAPI.getItemsNearby(playerPosition, collectRadius)
        
        -- Iterate over all the items found
        for _, item in ipairs(items) do
            -- Simulate interaction to collect the item
            itemAPI.interactWithItem(item)
            print("Collected item:", item.name)
        end
    end

    -- Set up a timer to call the collectItems function every collectInterval seconds
    timer.setInterval(collectInterval * 1000, collectItems)
end

Function Usage

Example of Calling the Function

To use the autoCollectItems function in a real-world scenario, you would initialize it with a radius of 5 units and set the collection interval to 2 seconds.

-- Start the auto collection of items with a radius of 5 units every 2 seconds
autoCollectItems(5, 2)

Explanation of Key Points

1. Imports: The code imports three hypothetical APIs (playerAPI, itemAPI, timer) that handle player interaction, item management, and timing functions respectively.

2. Input Validation: The function validates user inputs for radius and interval to ensure they are positive numbers. If inputs are invalid, it raises an error.

3. Item Collection Logic: The core functionality is wrapped in the collectItems local function, which retrieves items within the specified radius and interacts with each one.

4. Timer Setup: The setInterval function from the timer API is used to repeatedly call the collectItems function at the specified intervals, facilitating continuous collection.

5. Output: Each time an item is collected, its name is printed to the console, providing feedback on the collection process.

Conclusion

This implementation provides a robust method for automatically collecting items in a game setting using Lua. Adhering to best coding practices such as input validation and proper documentation ensures maintainability and clarity.
