Making my Sentry Shoot the Player

I’ve been working on a sentry system for my game, and I do not know how to proceed any further. I made a system where the sentry’s barrel faces the player, but I don’t really know how to make it shoot without becoming a minigun.

local TS = game:GetService("TweenService")
local RS = game:GetService("RunService")
local PS = game:GetService("Players")

local sentry = workspace.Sentry
local sentryFire = sentry.FiringPart

local burstCount = 5

local function attack(root)
	print(root)
end

local function lookAt(root)
	RS.Heartbeat:Connect(function(deltaTime)
		local distance = (sentryFire.Position - root.HumanoidRootPart.Position).Magnitude
		if distance < 20 then
			sentryFire.CFrame = CFrame.lookAt(sentryFire.Position, root.HumanoidRootPart.Position)
			return root
		end
	end)
end

game.Players.PlayerAdded:Connect(function(player)
	local char = player.Character or player.CharacterAdded:Wait()
	lookAt(char)
end)

Once it faces the player, use a part and fire it out at a velocity towards player using direction(partA.position - partB.position) and if it makes contact(detect using raycasts) do damage. Modules such as fast cast help optimize and improve projectiles. Also, you can add effects and sounds to the bullet for a better effect. Another alternative is just raycasting in a direction and dealing damage

#3

My problem is how to make the part not fly every heartbeat

#4

Task.wait() or use delta
Delta can really be helpful with heartbeat
Runservice.Heartbeat:Connect(delta(this delta))
use this delta to caculate how much time passes between frames, and once enough time passes, fire sentry.
You can also use spawn(funciton)
Hope you find this helpful

#5

Ill try that. Is there any information on spawn(function)

#6

it runs something that will not slow down other code ex.
while true do
wait(1)
print(“a”)
end
runs every second
while true do
spawn(function()
wait(1)
end)
print(“a”)
end
prints(“a”) every frame

#7

This may not be spefefic, do research in roblox API and documenation

#8

I got something else like this:

local start = os.time()
local frame = start - os.time()
print(frame)

All I need is a way to connect the function every 2 seconds

#9

locaal start = os.time()
local frame = start -os.time()
runservice.Heartbeat:connect(function
if frame > 2 then
start = os.time()
do something
end

end)
something like this

#10

every time I go near it, it just doesn’t update.

idk wtf is happening

#12

oh, frame should = os.time() - start
sorry, mistake on my behalf

#13

No I typed it wrong in the first place; you’re good

#14

Now it works, thank you so much!

#15

I was kinda wondering, how would I add burst attacks?

#16

Maybe use a for loop with a shorter interval that shoots, then pausing for a longer interval that doesn’t shoot before initiating the next for loop.

#17

Alright. I have a system where it shoots in a repeat-until loop and pauses at the end, but its slow and inefficient

#18

maybe in the function Lookat() above, you change the line
if frame > 2
to
if frame > var

and change the var when it is bursting.
For example in a burst var = 0.1 and later var = 2

#19

you would wait until 10 or so bullets were shot in a burst, then change wait(var in prev post) to 2, then repeat

#20

like this?

if frame > burst then
start = os.time()
sentry.attack(firingPart, root)
burst += 1
end
#21

no, maybe like a var named bullets shot in burst and adding 1 every time a bullet has been shot and if like 10 bullets have been shot, the increase burst, then at the end of that repeat.

if frame > burst then
	start = os.time()
	sentry.attack(firingPart, root)
	bulletsShot += 1
	if bursting == false then
		bursting = false
		burst=0.1
	end
	if bulletsShot == 10 then
		bulletShots =0
		burst = 2
		bursting = false
		--or just wait 2 and don't use the var bursting and just set burst to a fixed value
	end
end

like this
sorry if this is unclear/ variables are confusing
