Lua Sword Animation Handler

This Lua script manages character animations for a sword wielding character in a Roblox game. It includes functions for setting up animations, handling equipping and unequipping, and responding to player actions like running, jumping, and attacking.

Code Overview

The script includes the following key features:

• Animation Setup: Load various animations related to walking, idling, jumping, attacking, and equipping.
• Animation Control: Functions to play and stop animations based on player actions.
• Input Handling: Connects player actions to appropriate animation responses.

Key Improvements

The main task is to ensure that after an attack, if the player is not walking, the idle animation correctly plays. Below is the modified code addressing this requirement.

local Players = game:GetService("Players")
local rs = game:GetService("ReplicatedStorage")

local Player = Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")

local Sword = script.Parent

local Walk
local Idle
local Jump
local Attack
local Equip
local isWalking = false
local isAttacking = false

local function setupAnimations()
    workspace:WaitForChild(Player.Name)
    Character = Player.Character or Player.CharacterAdded:Wait()
    Humanoid = Character:WaitForChild("Humanoid")
    local Animator = Humanoid:WaitForChild("Animator")

    -- Check for Animator
    if not Animator then
        warn("Animator not found on Humanoid")
        return
    end

    -- Load animations
    Walk = Animator:LoadAnimation(rs.Assets.Animations.Walk)
    Idle = Animator:LoadAnimation(rs.Assets.Animations.Idle)
    Jump = Animator:LoadAnimation(rs.Assets.Animations.Jump)
    Attack = Animator:LoadAnimation(rs.Assets.Animations.Attack)
    Equip = Animator:LoadAnimation(rs.Assets.Animations.Equip)

    if not Equip then
        warn("Failed to load Equip animation")
    else
        print("Equip animation loaded successfully")
    end
end

local function stopAnimations()
    if Walk then Walk:Stop() end
    if Idle then Idle:Stop() end
    if Jump then Jump:Stop() end
    if Attack then Attack:Stop() end
    if Equip then Equip:Stop() end
    isWalking = false
    isAttacking = false
end

local function onRunning(speed)
    if Sword.Parent == Character then
        if speed > 0 and not isWalking and Humanoid.MoveDirection.Magnitude > 0 then
            isWalking = true
            Walk:Play()
        elseif speed == 0 and isWalking then
            isWalking = false
            Walk:Stop()
            Idle:Play()  -- Start Idle animation when stopping
        end
    end
end

local function onJumping(isJumping)
    if Sword.Parent ~= Character then return end

    if isJumping then
        Jump:Play()
    end

    -- Ensure Idle plays if stopping while jumping
    if isWalking then
        isWalking = false
        Walk:Stop()
        Idle:Play()
    end
end

local function onEquipped()
    print("Sword equipped")
    if not Equip then
        warn("Equip animation is nil, reloading...")
        Equip = Humanoid:WaitForChild("Animator"):LoadAnimation(rs.Assets.Animations.Equip)
    end
    if Equip then
        print("Playing Equip animation")
        Equip:Play()
    else
        warn("Equip animation is still nil after reload")
    end
    Idle:Play()
    if Humanoid.MoveDirection.Magnitude > 0 then
        isWalking = true
        Walk:Play()
    end
end

local function onUnequipped()
    print("Sword unequipped")
    Idle:Stop()
    isWalking = false
    Walk:Stop()
    isAttacking = false
    Attack:Stop()
    if Equip then
        Equip:Stop()
    end
end

local function onAttack()
    if Sword.Parent == Character and not isAttacking then
        isAttacking = true
        stopAnimations()  -- Stop all animations before attack
        Attack:Play()
        Attack.Stopped:Connect(function()
            isAttacking = false
            -- Ensure Idle animation plays if standing still after attack
            if not isWalking then
                Idle:Play()  -- Play Idle animation after attack if not walking
            end
        end)
    end
end

Humanoid.Running:Connect(onRunning)
Humanoid.Jumping:Connect(onJumping)
Sword.Equipped:Connect(onEquipped)
Sword.Unequipped:Connect(onUnequipped)
Sword.Activated:Connect(onAttack)

if Player.Character or Player.CharacterAdded:Wait() then
    stopAnimations()
    setupAnimations()
    if Sword.Parent == Character then
        onEquipped()
    end
end

Key Changes Made

• Adjusted the logic in the onAttack function to ensure the idle animation is played correctly after an attack when the player is not walking.

Usage Example

To utilize the script above, simply place it in a LocalScript attached to a sword object within your Roblox game. Ensure that the sword has appropriate animations set in ReplicatedStorage.

1. Equip the sword to engage animations.
2. Move your character to see the walking animation.
3. Jump to trigger the jumping animation.
4. Click to attack and observe that it returns to idle if not moving after the attack.

This script offers a robust framework for character animation within Roblox, showcasing best practices in Lua programming and game development. For further enhancement of skills, consider exploring courses on the Enterprise DNA Platform for data and game programming.
