I need help with my raycastHitboxV4 npc attacks

Help and Feedback Scripting Support
#1

Well what I want to do is add the raycashitboxV4 to my npc so that my npc has an attack according to the animations and his hitbox does not have excessive range since I do not want the npc to hit me from behind illogically since when I try the npc it does its function, it attacks but it doesn’t hurt me and it doesn’t play the sounds of damage. The truth is that I don’t receive any damage until the raycast tries to register the accessories and parts of the player but it marks them as an error in the console, Well here I leave the part of my script that contains the connected raycasthibox, it’s not all, but the rest has nothing to do with this. If anyone knows and can help me I would appreciate it. I’m a newbie to raycasting. I have almost no idea how to put it. Some examples would help thanks

First off, the variable attack is a function. Use target.Parent.Humanoid instead.

Another thing is that the variable name random is already taken by something from roblox. Change it to something else like rand or randomResult

Also both your OnHit functions are the same so you should move it into one function and call them on both hands. Having 2 separate ones makes you have to edit both if you change one.

Also do you have any errors, what are they?

im going to try that and yea i got errors in the console like Workspace.NoobZombie.Sys:98 attempt to index function with ´Parent´ the same error but with line 122 Workspace.NoobZombie.Sys:122 attempt to index function with ´Parent´

yeah thats probably because your using the attack function wrong.

this is how you would use your attack function:

attack(target) -- target would be a character

-- this would result in an error
attack.target.Humanoid:TakeDamage()

its this good?

local function OnHit(target, hit, humanoid)
	if attack.Parent:FindFirstChildOfClass("Humanoid") then
		attack.Humanoid:TakeDamage(10)

		if hit then
			local randomResult = math.random(1, 3)
			if randomResult == 1 then
				attack1:Play()
				local damage1 = script:WaitForChild("damage1"):Clone()
				damage1.Parent = target.Torso
				damage1:Play()
			elseif randomResult == 2 then
				local damage2 = script:WaitForChild("damage2"):Clone()
				damage2.Parent = target.Torso
				damage2:Play()
				attack2:Play()
			elseif randomResult == 3 then
				local damage3 = script:WaitForChild("damage3"):Clone()
				damage3.Parent = target.Torso
				damage3:Play()
			end
		end
	end
end

newHitbox.OnHit:Connect(OnHit)
newHitbox2.OnHit:Connect(OnHit)

no because attack is still a function. you cant access .Parent from a function

you have to get the humanoid hit by doing:

hit.Parent.Humanoid

I did what you said but now I don’t have a problem with the script but now my problem is that the npc won’t do any damage to the player I don’t know if I did something wrong or did i forgot to connect it im confused anyways here is the script part

local function OnHit(target, hit, humanoid)
	if hit:FindFirstChildOfClass("Humanoid") then
		hit.Parent.Humanoid:TakeDamage(10)
			local randomResult = math.random(1, 3)
			if randomResult == 1 then
				local damage1 = script:WaitForChild("damage1"):Clone()
				damage1.Parent = target.Torso
				damage1:Play()
			elseif randomResult == 2 then
				local damage2 = script:WaitForChild("damage2"):Clone()
				damage2.Parent = target.Torso
				damage2:Play()
			elseif randomResult == 3 then
				local damage3 = script:WaitForChild("damage3"):Clone()
				damage3.Parent = target.Torso
				damage3:Play()
			end
		end
	end

hit is the part being hit, it doesnt have a humanoid in it.

hit is parented inside the character so you will need to use hit.Parent.

Example

hit.Parent:FindFirstChildofClass("Humanoid")

everything else looks fine after that it should work unless you have other issues in your code.

Yes, it works very well, I don’t have problems in the console anymore, my only problem is that the raycast doesn’t do any damage. In fact, since I had this error, it could never do any damage, I don’t know, but I have a question and that is that I shouldn’t connect the OnHit function. somewhere? Since seeing my script well and it happened to me but there is a part of the script that takes the function that you had told me previously the attack (target) here its the part that i mean

			local target = findTarget()
			if target and target.Humanoid.Health > 0 then
				print("PLAYER FOUND", target.Name)
				humanoid.WalkSpeed = 12.6

				attack(target)
				break
			else
				humanoid.WalkSpeed = 12.6
				print("Moving to ", waypoint.Position)
				local waypointPosition = waypoint.Position
				humanoid:MoveTo(waypointPosition)
				repeat

u won’t do any damage if the OnHit function isn’t connected to a hit event.
