NPC touching player doing damage with a time delay?

So what I mean is that when my NPC touches a player, it will deal damage. But what my script does is make the NPC deal 5 damage repeatedly since a player is constantly touching the hitbox of the NPC. How would you fix this to make the NPC deal 5 damage every second?

npc = script.Parent
local human = npc:WaitForChild("NPC") --different humanoid name so npcs dont kill each other
local hitbox = npc:WaitForChild("HitBox") --welded a hitbox

hitbox.Touched:connect(function(hit)
        local hum = hit.Parent:FindFirstChild("Humanoid")
        if hum then
            local swing1 = human:LoadAnimation(script.Swing1)
            local swing2 = human:LoadAnimation(script.Swing2)
            local choose = math.random(1,2)
            if choose == 1 then
                swing1:Play()
            elseif choose == 2 then
                swing2:Play()
            end
            hum:TakeDamage(5)
        end
    end
end)

Do you mean it continuously deals damage after they touch the NPC and walk away or do you mean the NPC can only deal damage after 1 second has passed? Azarth 3141 — 6y

This should work:

npc = script.Parent
local human = npc:WaitForChild("NPC") --different humanoid name so npcs dont kill each other
local hitbox = npc:WaitForChild("HitBox") --welded a hitbox
local can = true

hitbox.Touched:connect(function(hit)
    local hum = hit.Parent:FindFirstChild("Humanoid")
    if can then
        if hum then
            can = false
            local swing1 = human:LoadAnimation(script.Swing1)
            local swing2 = human:LoadAnimation(script.Swing2)
            local choose = math.random(1,2)
            if choose == 1 then
            swing1:Play()
            elseif choose == 2 then
            swing2:Play()
            end
            hum:TakeDamage(5)
            wait(1)
            can = true
        end
    end
end)

Can only damage once per second.

local tabl = {}

local function damage_player(player, hum)
    hum:TakeDamage(5)
    tabl[player.Name] = tick()
    -- Reset the time we last touched the npc
end

script.Parent.Touched:Connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player and player.Character then 
        local hum = player.Character:findFirstChild("Humanoid")
        if hum and hum.Health > 0 then 
            local indexed = tabl[player.Name]
            if indexed then 
                -- Player has touched the nps before.
                if tick() - indexed >= 1 then 
                    -- if the last time we touched is more than 1s ago. 
                    damage_player(player, hum)
                end
            else
                --Player isn't in the table yet, so damage anyways and index them.
                damage_player(player, hum)
            end
        end
    end
end)

Damages continuously after walking away.

local tabl = {}

local function damage_player(player, hum)
    spawn(function()
        while true do
            if hum.Health <= 0 then
                break
            end
            hum.Health = hum.Health - 5
            wait(1)
        end
        print(player.Name.. " is dead to me.")
    end)
end

script.Parent.Touched:Connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if player and player.Character then 
        local hum = player.Character:findFirstChild("Humanoid")
        if hum and hum.Health > 0 then 
            local indexed = tabl[player.Name]
            if not indexed then 
                tabl[player.Name] = true
                damage_player(player, hum)
            end
        end
    end
end)
