Eye kills player upon being spotted

Help and Feedback Scripting Support
#1

Hi there! In this topic, I want to talk about a mechanic that I’ve always wanted, but haven’t gotten to making it because of my lack of experience with coding.

Basically, An eye that surveys the room, and when it spots a player, aims at them, and kills them slowly.

I know it has something to do with Rays and such, but I can never translate/form it into a script, I don’t really know how to code that well :sweat_smile:. If anyone can give me either a short script, or tips on how to make it myself, that would be greatly appreciated. Thank you in advance for the help!

This is actually pretty easy to do!
First, you will need to get all players within a certain radius. You can do this by looping through all the players and checking the distance between their character and the eye.

After you get a player, you need to make the eye aim at them. You can use CFrame.lookAt for this.
Then, do a raycast from the eye to the player. If it hits, damage their humanoid.

So basically, what I do is make a loop to check if a player/s is inside the max distance/radius of the eye, then check with a raycast if it hits a player. If it does, then I make it so it damages them? Also you can probs see I’m pretty bad at scripting hehe :sweat_smile:. Thanks anyways mate!

I’m not them, but yes.

The events should go in this order:

  • Player is within distance of eye, can be done with a loop and magnitude checks between the eye and the players character, more specifically the players HumanoidRootPart.
  • Eye can actually see the player, raycast from the eye to the players character.
  • If the RaycastResult is a descendant of the players character, like its head, HumanoidRootPart, etc, then have the eye face them using Cframe.lookAt.
  • Start dealing damage!

I’m using this script I got from someone else for the raycast script, and it works. But I don’t know how I can make it so that it hurts the player, and surveys the area as well. Plus, it also snaps in place. Here’s the script:

local TeddyAI = script.Parent


local function getHumPos()
	return (TeddyAI.Position)
end

local function findPotentialTarget()
	local players = game.Players:GetPlayers()
	local maxDistance = 100
	local nearestTarget

	for index, player in pairs(players) do
		if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
			if player.Character.Humanoid.Health > 0 then
				local target = player.Character
				local distance = (TeddyAI.Position - target.HumanoidRootPart.Position).Magnitude

				if distance < maxDistance then
					nearestTarget = player
					maxDistance = distance
				end
			end
		end
	end

	return nearestTarget
end
function canSeeTarget(target)
	if target and target:FindFirstChild("HumanoidRootPart") then
		local origin = TeddyAI.Position
		local direction = (target.HumanoidRootPart.Position - TeddyAI.Position).unit * 100
		local ray = Ray.new(origin, direction)
		local ignoreList = {TeddyAI}

		local hit, pos = workspace:FindPartOnRayWithIgnoreList(ray, ignoreList)

		if hit then
			if hit:IsDescendantOf(target) then
				if target.Humanoid.Health > 0 then
					local unit = (target.HumanoidRootPart.Position - getHumPos()).Unit
					local lv = TeddyAI.CFrame.LookVector
					local dp = unit:Dot(lv)

					if dp > 0 then
						return true
					end					
				end
			end
		else
			return false
		end	
	end
end

while true do
	local target = findPotentialTarget()
	if target and canSeeTarget(target.Character) and target.Character.Humanoid.Health > 0 then
		TeddyAI.CFrame = CFrame.lookAt(script.Parent.Position, target.Character.HumanoidRootPart.Position, TeddyAI.CFrame.UpVector)
	else
	end
	game:GetService("RunService").Heartbeat:Wait()
end
