How to make an AI LASER TURRET in Roblox Studio #1 - Turret Setup and Kinematics

[@np51486]

Very sick video, thanks for uploading. The way the turret moves reminds me of how Yaskawa and Fanuc robotic arms operate when doing a bunch of cartesian plane movements, definitely gonna be a sick addition for my turret animations!

[@candycorn-t8h]

this guy the best he legit just gave us model dont even need to control c and v

[@BRicey]

Hey actually watch the video don’t just take it…. (I mean no one’s stopping you butttt)

[@rashy15]

truly a roblox studio master class 😭

[@navy_2467]

You should try making some soldier ai. Taking cover, suppression fire, etc would be interesting to see. I know yellowmustang has already made one but it would cool to see how it was fully made and the science behind it.

[@MichaelObamaSon]

thank you for all your videos. you are an amazing teacher.

[@BRicey]

You're very welcome!

[@MatteoP04ita]

I think I will watch all the videos about Cframes you cited. Being able to operate with CFrames lets you create anything

[@BRicey]

Indeed… and it also transfers to other game engines and other applications too

[@AgentRobloxDeveloper]

very cool i like it

[@robnoob6820]

this is sick

[@KindaSalty]

I Really Needed This, Thanks! 👍

[@itsdakideli755]

These tutorials are amazing!

[@BRicey]

Glad you like them!

[@thejr9944]

As someone else has previously mentioned, how do you know how to use methods :Cross() and :Angle()? Aside from that, this video is a great follow up video to finding angles between two vectors 👍

[@BRicey]

I have a video going over angle, check the description... cross is just weird it still kind of feels like black magic to me, but in short it imagines two vectors making up their own plane, and returns a vector perpendicular to the plane with the magnitude corresponding to something about the vectors... just getting the perpendicular unit vector is all I've ever used it for

[@plshelpmewithtds]

I really want the submarine game to come out! please upload videos on it.

[@Unknown-ym3ds]

That's certified cool 😎

[@MatteoP04ita]

Great! I voted for another video tutorial (player controlled mortar) but this one will still be useful

[@dev_snips]

Been a developer for nearly a decade and i still do not understand a thing about anything related to Roblox's physics. I've attempted to follow this well made guide, and i got as far as attaching the hinges. Except that my hinges don't drop with gravity. And afterwards, the small boat that i had set up basically just decided it'd fling itself for absolutely no reason, that being with or without the little turret. Got to admit that Roblox has the most unfriendly physics engine I've seen. I quite literally do not understand what the hell is causing all these problems. It's a shame though, since I was planning on expanding these turrets over to other moving objects. Back to CFrame i go, at least CFrame is reliable.

Hey man, loving your tank turret vids! I've been working on my own tank project and tried using your method for getting the turret to follow the mouse. At first I was stoked cause it worked perfectly in your demo - the turret would smoothly rotate to match the mouse angle. But when I plugged it into my tank, it didn't work right. No matter where I moved the mouse, the script only showed the starting angle of the turret, not the actual rotated angle. Any ideas what could be tripping me up? A quick update video explaining common issues would be super helpful. Or if you have time to send over some example code or tips, I'd really appreciate you taking a look under the hood! Keep up the awesome tutorials - they're saving me a ton of time debugging this tank lol. Let me know if you can help!

[@HanzTheGamer]

I got 2 questions - Can you make it target NPCs instead of players? -Can you customize the turret without breaking it?

[@AzizBeess]

I would use RayCast if not your video! Thx for the tutorial. I dunno get those math things

[@rashy15]

if you could show a visual representation of how the angle and cross stuff works

[@ttpechon2535]

How do you find out which functions and that to use? Like how do figure out which things you will use and what methods, as I have no idea where you would even start. When I read through the defiintions of the functions I draw a blank on what they do, PointToObjectSpace sounds like it would point to and object, and then you read the definition and suddenly it seems to be something else. Is it just experience and hearing about these things and knowing how they work because you used something similar, or is it common sense? I'm guessing you know how to do this with math, and then you're finding the api equivalents to accomplish this right? Anyway thanks for making these, you really explain what your doing and it really helps, they're way to many people who make vids say do this then that and it shows you how to do it, but not very well and you don't understand it.

[@BRicey]

Great question! I recommend just browsing through the documentation on the Roblox Creator Hub and seeing what might be useful; Roblox has some of the best docs around! And no, I don't know how to do this with math. I'm in the process of learning these things, but I've only taken up to a calculus course, and almost all of the math I use in Roblox (and 3d games in general) is linear algebra. For me, its just guess and check until it becomes intuition. Just play around with the functions, use videos like these to add tools to your toolbox... learning is just a process!

[@ttpechon2535]

@@BRicey Excellent, thanks! I'll have to look into Linear Algebra and that to.

[@np51486]

How performance intensive do you think this turret would be? Im thinking of rendering them locally on the client with about 15-30 instances of them being active at a time

[@BRicey]

I mean it’s running every frame but it’s only doing basic calculations so it shouldn’t be bad. The enemy detection is the worst perf impact, but you can avoid that by putting it on a timer

[@np51486]

@@BRicey Sounds great! I dont plan on using any player detection, the turrets are to be centrally controlled and targeted by the player and hit detection will be a formula based on distance of turret from the target

[@ItsLeeeroy]

This would be useful in a defense type tycoon

[@lothomost2231]

Will you cover how to make it not target certain players like the owner of the turret?

[@P.R.C.E-official83]

When I run the simulation, the target part keeps disappearing

[@RandomPerson-lu8ln]

This will genuinely help out a lot, thank you Question, does this work on moving things like cars? Note: seeing a fellow person wanting to make a tank as well, I wanted to know how you could actually fix these problems?

[@BRicey]

Theoretically it should work on tanks and cars, but I guess it doesn't. I kinda want to make a tank one day so I guess you could wait for that; but I would encourage you to try and play with it yourself.

[@RandomPerson-lu8ln]

@@BRicey thanks for the recommendation! My friend and i will take note on this.

[@penguinpenguin3156]

Hey Im on episode three of your tycoon series can you tell me how to fix ServerScriptService.Tycoon:74: attempt to index nil with 'Event'

[@zetta6656]

What if my turret is a naval turret and I want the housing to rotate but the barrels to go up and down?

[@romanchaidiouk2788]

dude there is no way... I saw your previous video from 6 months ago a couple days ago and really wanted to know how to make this work with 2 hinges cause my Y axis hinge was bugging out and I was struggling to find a way to fix it. I was literally ganna try to leave a comment on your most recent video asking for the turret video but your most recent video was the video I wanted. this video was made for me 😭😭😭

[@romanchaidiouk2788]

am I the main character? are you living in my walls watching my every move? GET OUT OF MY HEAD

[@BRicey]

I'm always watching 👀

[@faronb651]

nice video

[@Xackory]

Smart kid. Subbed

[@lmao4383]

I would love this turret to have a whitelisted player list so it doesnt shoot everyone.

[@voxeledphoton]

I made a quick module that lets you get the nearest character given a table of characters. Has a function that would let you specify a player table too (just remember the vector findNearest returns will need to be added to the position of the turret for getting the direction variable) local module = {} local Players = game:GetService("Players") function module.addPlrCharacters(charTbl:{}?,plrWhitelist:{}?) local chars = charTbl or {} local plrs = plrWhitelist or Players:GetPlayers() for _,plr in plrs do if plr.Character then table.insert(chars,plr.Character) end end return chars end function module.findNearest(pos:Vector3,chars:{}?,maxDist:number?) local charTbl = chars or module.addPlrCharacters() local nv = nil local nd = maxDist or 1000 for _,char in charTbl do local hrp = char:FindFirstChild("HumanoidRootPart") if hrp then local dirVect = hrp.Position-pos if dirVect.Magnitude

[@barnacolium6947]

idk if im right in thinking this but could you have the base not anchored but welded to smth else like a moving car and it still work fine? im imagining that it does due to the direction variable being recalculated every frame

[@barnacolium6947]

nvm doesnt work lol, i think with the ref object also needing to be anchored is wat breaks it

[@meowyhearts3030]

Hi ,, could you make a tutorial where if a player is not looking at a certain object a part moves , and when that part moves a text label will pop up? just asking because I’m experimenting with stuff :]]

[@Chris_Hansen123]

still waiting for the next devlog

[@yumiyumee]

hey Ricey, your videos are really cool lol. Can you help me out with something? I have a gibbing system on my game, it gets gibs based on the ray position of a gun, but the formula I'm using to get these gibs doesn't work well. Do you have any other formulas that I could use? I made a topic in DevForum but no one replied.

[@simonixen]

can u make a model of the turret? i just want to use this for learning and i dont bother making a model

[@BRicey]

so so sorry I completely forgot to add these to the description... double check and make sure the template link I pasted works. Thanks!
