Roblox Script Generated by ScripterAI

"script an NPC that follows the closest player in a custom walk animation that is customizable inside the script, also an idle animation that is customizable inside the script, idle animation players when player is 50 studs away, where does script go"

The script for the NPC can go in a server script inside the NPC's script folder. Here is an example script:

local npc = script.Parent
local walkAnimId = "rbxassetid://YourWalkAnimationIDHere"
local idleAnimId = "rbxassetid://YourIdleAnimationIDHere"

local function findClosestPlayer()
    local closestPlayer = nil
    local closestDistance = math.huge
    for _, player in pairs(game.Players:GetPlayers()) do
        local distance = (player.Character.HumanoidRootPart.Position - npc.HumanoidRootPart.Position).Magnitude
        if distance < closestDistance then
            closestPlayer = player
            closestDistance = distance
        end
    end
    return closestPlayer
end

local function playAnimation(animationId, speed)
    local animation = npc.Humanoid:LoadAnimation(animationId)
    animation:Play()
    animation:AdjustSpeed(speed)
    return animation
end

while true do
    local closestPlayer = findClosestPlayer()
    if closestPlayer then
        local distance = (closestPlayer.Character.HumanoidRootPart.Position - npc.HumanoidRootPart.Position).Magnitude
        if distance > 50 then
            playAnimation(idleAnimId, 1)
            npc.Humanoid:MoveTo(closestPlayer.Character.HumanoidRootPart.Position)
        else
            playAnimation(walkAnimId, 0.5)
        end
    else
        playAnimation(idleAnimId, 1)
    end
    wait(0.1)
end
