my exp script doesnt work properly it gives exp to all players?

when i made a working exp script it gives the exp to all players not the player who killed the npc so can someone help me with it to make it gives exp only to the player who killed the npc or the last attacker

this is the script

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() for _,Player in pairs(game.Players:GetPlayers()) do if Player:FindFirstChild("leaderstats") then Player.leaderstats.Exp.Value = Player.leaderstats.Exp.Value +4 end end 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() -- local now = os.time() -- if now - lastMoan > 5 then
-- if math.random() > .3 then -- zombie.Moan:Play() ---- print("playing moan") -- lastMoan = now -- end -- end wait(2) end
