How can i fix a monster not killing other players?

So i was making a RTX version of the Library from Doors, and credited LSPLASH of course, then i put this code in Figure to make it kill players

local zombie = script.Parent

for _, script in pairs(zombie.ModuleScripts:GetChildren()) do
    if not game.ServerStorage:FindFirstChild(script.Name) then
        script:Clone().Parent = game.ServerStorage
    end
end

local AI = require(game.ServerStorage.ROBLOX_ZombieAI).new(zombie)
local DestroyService = require(game.ServerStorage.ROBLOX_DestroyService)


local function clearParts(parent)
    for _, part in pairs(parent:GetChildren()) do
        clearParts(part)
    end
    local delay
    if parent:IsA("Part") then
        delay = math.random(5,10)
    else
        delay = 11
    end
    DestroyService:AddItem(parent, delay)
end

zombie.Humanoid.Died:connect(function()
    AI.Stop()
    math.randomseed(tick())
    clearParts(zombie)
    script.Disabled = true
end)

local lastMoan = os.time()
math.randomseed(os.time())
while true do
    local animationTrack = zombie.Humanoid:LoadAnimation(zombie.Animations.Arms)
    animationTrack:Play()

    wait(2)
end

I tested the game, but Figure just goes to a point and hits whatever blocks it, how can i fix this?
