Death Counter Function for Friday Night Funkin' Psych Engine v1.0

This document outlines a Lua function designed to track the death count in the Psych Engine version 1.0 of Friday Night Funkin'. This function will increment a counter every time the player character "Boyfriend" loses a life, handling input validation and other best practices.

Function Overview

The function will perform the following:

• Initialize and maintain a death counter.
• Allow the counter to be incremented.
• Provide a function to retrieve the current count.
• Include robust input validation.

Code Implementation

Death Counter Code

-- Death Counter Module for Friday Night Funkin'
local DeathCounter = {}
DeathCounter.count = 0

--[[
    Initializes the death counter to zero.

    Parameters: None
    Returns: None
]]
function DeathCounter:init()
    self.count = 0
end

--[[
    Increments the death counter by one.

    Parameters: None
    Returns: integer - updated death counter value
    Raises: error if called during an active game state
]]
function DeathCounter:increment()
    if not self:isGameActive() then
        error("Cannot increment death counter if the game is not active.")
    end
    self.count = self.count + 1
    return self.count
end

--[[
    Retrieves the current death counter value.

    Parameters: None
    Returns: integer - current death counter value
]]
function DeathCounter:getCount()
    return self.count
end

--[[
    Checks if the game is currently active.

    Parameters: None
    Returns: boolean - true if the game is active, false otherwise
]]
function DeathCounter:isGameActive()
    -- Placeholder for actual game state check
    return true
end

return DeathCounter

Key Features

1. Initialization: The counter starts at zero using the init method.
2. Incrementing: The increment method safely increments the counter, ensuring the game is active.
3. Retrieving Count: The current death count is retrievable through the getCount method.
4. Game State Check: The isGameActive method can be adjusted to reflect the actual game state checking logic.

Example Usage

Here’s how you can utilize the Death Counter in your game:

-- Load DeathCounter module
local DeathCounter = require('DeathCounter')

-- Initialize the counter at game start
DeathCounter:init()

-- Simulate the game loop where the player dies
while true do
    -- Assuming a condition triggers player death
    local playerDied = true -- replace with actual game-condition
    if playerDied then
        local newDeathCount = DeathCounter:increment()
        print("Deaths: " .. newDeathCount)
    end
    
    -- Exit loop condition (to prevent infinite loop in example)
    break -- replace with actual game exit condition
end

-- Print final death count at the end of the game
print("Final Death Count: " .. DeathCounter:getCount())

Conclusion

This Lua implementation provides a systematic way of tracking death counts in the Friday Night Funkin' Psych Engine. The design follows best practices, again emphasizing modularity, input validation, and clear documentation.
