How can I make it so this part can only damage NPC's once?
I have tried running a for loop to check for each part that hit it, and then check to see if they have a humanoid, or in this case, the humanoid called "Enemy." I would like to know if there is a better way to make sure a swing only damages once per slash?
--//Check for hits\\--
blade.Touched:Connect(function(hit)
--Check if we are swinging\\--
if not swinging then return end
--Validate humanoid\\--
for i = 1, hit do
local hitHumanoid = hit.Parent:FindFirstChild("Enemy")
if hitHumanoid then
if canDamage then
--//Damaage Humanoid\\--
hitHumanoid[i]:TakeDamage(math.random(mindmg.Value,maxdmg.Value))
canDamage = false
local tag = Instance.new("ObjectValue")
tag.Name = "creator"
tag.Parent = hitHumanoid[i]
tag.Value = player
wait(8)
tag:Destroy()
end
end
end
end)

I can think of 2 ways to do this.
You could make a blank table and whenever it damages a humanoid add the humanoids parents name to the array, then before damaging check if the humanoid parents name is in the table.
local intable = false
for i, v in ipairs(MyTable) do
if v == humanoid.Parent.Name then
intable = true
end
end
if intable = false then
humanoid:TakeDamage()
table.insert(MyTable, humanoid.Parent.Name)
end
downside to this is the humanoid will not be able to be hurt again until the script is reset. and if 2 humanoids have the same name then they both wont be hurt anymore.
Or when the humanoid is damaged add some object to the humanoid and name it hurt then check if it there before hurting it like this
local time = 100--the amount of seconds until the humanoid can be hurt again
if humanoid:FindFirstChild("Hurt") == nil then
humanoid:TakeDamage()
local hurt = Instance.new("BoolValue",humanoid)
hurt.Name = "Hurt"
game.Debris:AddItem(hurt,time)
end
If you want them to not be hurt again until they reset then just remove game.Debris:AddItem(hurt,time)
number 2 is the best option unless you only want them to be hurt once and never again then you would use option 1

What you want to do is declare canDamage as true at the top of the script outside of the function. As soon as the blade as touched a part that is a character, make canDamage = false.
This way it wont damage anything else until you set canDamage back to true (which should be set after a wait(#) time.
canDamage = true
Blade.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild('Enemy') then -- check to see if it was a person with a humanoid
local humanoid = hit.Parent.Enemy
if canDamage == true then -- will only damage if canDamage is true
canDamage = false -- set it to false so it wont damage again right away
humanoid:TakeDamage(math.random(mindmg.Value,maxdmg.Value)
wait()--insert how long you want it to wait before it can damage again
canDamage = true
end)
