FULL 3D ENEMY AI in 6 MINUTES! || Unity Tutorial 

I was almost in tears listening to your voice because Brackeys has taken a break from youtube 😢😢😢😢😭😭😭😭

whoever followed through this tutorial without pausing the video once is a god

Amazing tutorial, thank you!! Adding in notes on snags I hit for future reference: How To Add/Set Layer Masks: (1) Click on your game object, in inspector on the upper right is the Layer dropdown. Add twhatIsGround/Enemy/etc as new layers and set accordingly Enemies Not Moving: (1) Make sure your ground and player objects have colliders Projectile Problem: (1) Make sure your projectile has a Rigidbody component added Adding NavMesh Components: (1) You can now add them directly via Unity's Package Manager. Go to Window -> Package Manager -> Packages -> AI Navigation and install that

I feel like this guy might be our Brackeys from now on

"in 6 minutes" ... *does tutorial in hyper speed*

what. a. timeless. tutorial. literally as i write this comment this tutorial work even after 4 years later.. thanks unity for making such beginner friendly engine and thanks to you for making such comprehensible tutorial!

Bruh 6 minutes......im new to C# and I understood that perfectly, you're a fucking beauty

To anyone having the player enemy fall or disappear... Make the empty Game Object that you put the Nav Mesh Surface on not a child object of your enemy. This worked for me, Best of luck!!!

Best Tutorial for Enemy AI on RU-vid

This tutorial is definitely one of the bests. The only thing I would probably add is the idling function. That way the enemy would stop for a sec or two instead of constantly running around

This is how most of tutorials should be! I love everything about it. Directly to the point and explaining just what is needed. Awesome job and Thank you!

This tutorial is amazing even if am not using unity, really opened up one thing i overlooked separating chase range and attack range .thanks for the breakdown of the base of ai before expanding how smart it behaves .just subbed

If you followed this tutorial and your Player is not recognised by the enemy so it never goes toward the player, it might be because your player doesn't have a collider. So, add a capsule collider or something like that to your player it could fix it. I've been struggling with that the past 15 min 😁

I keep coming back to this one. surprisingly simple, surprisingly effective.

I don't understand only one thing.... HOW ARE YOU SO GOOD?!

Absolutely fantastic tutorial video! I found it absolutely invaluable as a starting point for creating my first Enemy AI. And I expanded it by adding behavior for patrol paths/waypoints, as well as definable 'Idle time' between WalkPoints, combined with a bool option to randomize idle time as well. :)

If anyone is having trouble with the baking section you just have to set the areas you want to bake to static in the inspector.

Nice script for enemy AI to completely kill all your hope for any tiny bit of performance as soon as your number of enemies is above 10. Good job

Damn right to the point. Very nice tutorial. You didn't waste a moment. Thx for this tutorial.

Mans types so fast visual studio can’t keep up

This channel is so underrated

I have a weird, but small issue. When the enemy is attacking, the bullet spawns but it won't turn with the enemy. So it begins firing when I enter the attack range, but it's never facing me and never updates to my current position.

had a little trouble with figuring out layers but got it working after a little more research :) Thanks dude!

This tutorial really helped! Thanks! I am working on FPS AI and a can't tell you how much this helped! Thumbs up!

Dave if you continue creating videos like this one you will be the next Brackeys on RU-vid or even bigger, congratulations and thanks for this amazing content. 👍

I look away for one second and it's already the next video. Great tutorials btw.

for anyone whos enemy is falling thru the floor, click window, ai, navigation, and then select the floor and anything else u want the enemy to walk on, then click bake and it should work

The “Nav Mesh Surface” script doesn’t appear the same way yours appears. Any way to fix?

THIS IS AMAZING! Don't stop making these tutorials.

Awesome tutorial! This worked out amazing in my game.

Player is'nt attacking and movin. Test everything not working. Any help will be appreciated

Your channel looks very very good, your voice reminds me brackeys too hahaha

There are a few changes I made to this. The AI needs to make sure that the path is complete before chasing or attacking the player. Otherwise, it will walk and float across gaps, walk through walls, and attack through walls. For enemies that shoot projectiles, I made them raycast towards the player to see if the player is within their line of sight, and if they don't see the player, they move closer until they can actually hit the player with the projectile. Otherwise, they get stuck trying to shoot a player from behind a wall.

There no navmeshagent for me and it is driving me insane

Look into coroutines instead of invoking. Gives so much more flexibility and invoking is also more expensive. Amazing tutorials as always.

dude don't stop making videos you have some amazing content that A LOT of people can learn from

I don't know if you still read these but thank you!! this helped me so much. it was straight the point no chitter chatter. Greate video.

This is great! Straight to the point. I have a request please

I love your video style and clear code. Subscribed!

This was excellent. Clean, simple and concise explanation of how to use Unity's NavMeshAgent system. I've already got a 3D model of this demon-lord looking creature with movement and animation controls programmed, even did the IK adjustments to keep his feet perfectly on the terrain. Now I need to implement AI agents to control enemies and this showed me how to get that working. Gonna start with one simple ranged attack spell then hook up the whole game system for spells and weapons to AI agents based on what attacks they're able to use. 😄

so ur saying i could of just downloaded the script😐

I'm really happy to find your channel with all-new, simple, and specific videos, and I hope to find Oculus VR Rift tutorials as well, subscribe.

This is a brilliant tutorial, but I'm stuck on the layer masking. I've never done it before, how do I go about creating them properly?

Best youtube on Game Dev hands down. Especially now that Brackeys gone, you will grow even more

This is Brackeys Channel. I think He is doing Side Business from this channel.... hahaha . Exact As Brackeys

hi, when i use this script it works fine but my game becomes choppy / laggy. any help on how to fix this ?

Hey, it shows me an error at line 31: Object Reference not set to an Instance of an object? and my ai doesnt move, how do i fix those things?

So I’ve been creating a game and this was really helpful. Though I am making a horror game. But still was helpful! Thanks!

btw u should do it like this: make it so if the enemy sees you with their own eyes with raycast and that they are in range of the sight, this would be infinitely more realistic.

Nice! I spent a long time doing the detection, I wanted it to be like if the player is out of sight the enemy will move to where he was last seen, it took a long time because it was the raycasts being dumb, *nice tutorial tho*

There is no Bake Button.. I cant bake

I literally just straight up assumed you ripped one of Brackey's videos I was so confident that was his voice! It's funny how two game development people on youtube sound so similar lol, thank you for the video!

I have 2 issues. One the enemy doesn't patrol it just kinda stands there. the walkpoint keeps changing but the enemy doesn't move. Also when the enemy reaches a certain point it just stops and refuses to move. Any help would be great.

I can't find the NavMeshSurface option... can anyone help with this?

How do you download the nav mesh

Thankyou , this script acts as a nice base to build upon more complex behaviours.

Thank You, This really helped me learn more about NavMeshAgents. I modified the code and used it to make an AI for my Game.

I altered this to make an enemy that walks between its start point and a given point, after chasing and losing sight of you it returns to its start point.

dude u r awesome i was looking for this for a couple of days thank u so much ♥

Not sure what I am doing wrong, I downloaded your code and named layers to WhatIsEnemy, WhatIsGround etc. yet the layer masks are not working. I only have a ground to mask with right now so I gave it WhatIsGround and baked it. I have all the imports right in the Nav Mesh Agent yet the object is still falling through the ground. Originally the enemy was floating on the y axis, but now it is just falling through the ground.

I seriously wonder if the creators of these types of tutorials actually feel like they're teaching something... no "whys" whatsoever - just having the viewer copy code.

hmm... the NavMeshSurface doesn't have the baking options or most of the others you have /: pls help

I did everything like the tutorial but when i try to play the ai go to space any solutions?

help my ai IS FLYING AWAY

when i use it my enemy flys 100 billion miles in the air at lightspeed. how do i fix this????

Amazing tutorial, but I was wondering how could a speed variable be implemented in the ChasePlayer function, so that different enemies may have different speeds

The only thing I can say about this video is you've got a new subscriber :)

Thanks for the tutorial but I have one question. When the enemy comes in sight it flies towards me and I keep getting this error: "SetDestination" can only be called on an active agent that has been placed on NavMesh.

Great tutorial, I followed all the steps but I have a slight issue. I made a capsule just so I can test it out, but it isn't moving. I copied and pasted the code and followed everything but I don't know what I could've missed. when I add the random walk, it does work.

The voice is the same with Brackeys?

Very usefull tutorial! I've already used it to program some turrets to fire at me and a ground enemy to chase and attack me!

it doesnt work for me the enemy just flies into space like it has reversed gravity

I Wish He Was More Clear On The Installation For Navmesh!

Dave the enemy's aren't shooting with me how do i fix this aside that a great tuturial

Very good videos but why you don't show hierarchy? please show so i can understand

followed this exactly and when i tried to play it he plummeted the earth at 350 mile per hour Edit: found the problem and it was how close he was to the ground just get him closer to the ground and it should work

This boi is helping me so much. You are amazing

This is exactly the kind of tutorial i need. And is the exact solution i was looking for. Thank you so much!

Great tutorial, but one big thing is missing. Sometimes the random walkpoint is set in a wall or some obstacle and the "AI-Object" doesn't move and is stuck....

Great tutorial! I also like how you say projectile. "Project tile". Totally going to steal that :D

Hey, so I'm completely new to coding and unity in general, and I'm having issues with my enemy falling through the map extremely quickly, and it says the walk point is what I'm assuming is the position of the entity. Any idea why?

my enemy keeps shaking like it's drunk, and when i shoot it with a force, it goes back to the place it was before and continues to be drunk. what in the world is happening

Hello Dave, great video! I followed this tutorial for a game where a monster chases a first person player. Everything works great except the patrolling. I can see it setting new walk points in the inspector, but the monster does not go to them. Any idea how to fix this? Thanks!

Great video but for me they just fall right through the floor, i did everything correctly with baking but it just doesnt work any idea on what the issue could be?

my enemy randomly sinks through the map edit: what i mean is that the Y value is going crazy - it will move a bit to the left, then shoot downwards in the space of around a millisecond as soon as the game starts, without travelling there. It just instantly warps below the map. I am using terrain that is very mountainous as the ground layer, though. maybe that is the problem? could you help me please? edit 2: the same thing happens with the exact same ground that you are using.

ur really amazing iam really looking forward for ur next tutorials !!

Now I've downloaded the zip file but how I get those godes in the unity editor?

I really like this because it's the only Tutorial I have found where ai patrols without multiple patrol points

Really enjoyed this tutorial. You've gotten my sub. I had two issues, one being my projectiles would only move in one direction, even if the enemy rotated. Two being the enemy would rotate on the X axis when shooting -- I only wanted it to rotate on the Y axis. These two were quite easy to fix. In AttackPlayer() Vector3 newPlayer = player.position;

Super helpful, man. Thanks!

Can someone help me out if n put the NavMeshSurface on an object it doesnt show me the same menu Theres an empty slot called NavMeshData and an agent type ID Edit and no bake option

hey dave i'm working on a 2d top down shooter and i'm using your script from the first projectile gun tutorial without reloading,the bulletsleft and the ray. when i do a burst gun instead of firing like RATATA, RATATA, it fires like RATATATA, RA, RATATATA, RA, maybe because it invokes resetshooting also with the burst projectiles. i'm also always shoting when i use the right analog because it moves with the left joystick and rotates with the right joystick. here is my code. can you help me?? using System; using System.Collections; using System.Collections.Generic; using UnityEngine; public class player : MonoBehaviour { //general Rigidbody2D rb; //movement public float movespeed; Vector2 movement; public FixedJoystick movejoystick; //rotation public float rotatespeed; public Joystick rotatejoystick; //shooting public GameObject bullet; GameObject bulletshotted; public Transform head; public float bulletspeed; public bool readytoshoot; public float timebeetweenshooting; public guncontainer gun; public int bulletspertap; public int bulletsshot; public float timebtwnshots; public bool allowinvoke; void Update() { //movement float horizontal = movejoystick.Horizontal; float vertical = movejoystick.Vertical; movement.x = horizontal; movement.y = vertical; //rotation Vector3 movevector = (Vector3.up * rotatejoystick.Horizontal + Vector3.left * rotatejoystick.Vertical); if (rotatejoystick.Horizontal != 0 | rotatejoystick.Vertical != 0) { transform.rotation = Quaternion.LookRotation(Vector3.forward, movevector); } //shooting if (rotatejoystick.Horizontal != 0 && readytoshoot || rotatejoystick.Vertical != 0 && readytoshoot) { Shoot(); bulletsshot = 0; } timebeetweenshooting = gun.timebetweenshooting; bulletspertap = gun.bulletspertap; timebtwnshots = gun.timebtwnshots; } void FixedUpdate() { rb.MovePosition(rb.position + movement * movespeed * Time.deltaTime); } public void Shoot() { if (bulletsshot < bulletspertap) Invoke(nameof(Shoot), timebtwnshots); readytoshoot = false; bulletshotted = Instantiate(bullet, head.position, head.rotation); Rigidbody2D bulletrb = bulletshotted.GetComponent(); bulletrb.AddForce(head.up * bulletspeed * Time.deltaTime, ForceMode2D.Impulse); Destroy(bulletshotted, 2); bulletsshot++; if (allowinvoke) { Invoke(nameof(Resetshooting), timebeetweenshooting); allowinvoke = false; } } void Awake() { rb = GetComponent(); readytoshoot = true; bulletsshot = 0; allowinvoke = true; } private void Resetshooting() { readytoshoot = true; allowinvoke = true; } } thanks dave!

Now I understand the difference between blueprints and c#.

would be cool if you showed us what the scripts you included did and what they are used for. Sounds like you had somewhere to be right after this video with how fast you were going and how little you explained 5/10 tutorial

Great tutorial man, it’s a big help cause I’m very new to enemy ai

How do I add those NavMesh Files? pls help :(

Thank you, even helped out in the discord.

Hello, thanks for the tutorial. Im very new to all this so im struggling a little. I made a sphere as the enemy, and i gave it all the scripts and stuff. I followed the tutorial until 5:27 basically. But my enemy is not moving, and it just shoots whenever it wants. it shoots at the player which is good, but i basically have a turret with infinite range in my game. How can i make the sphere actually move and act like an enemy? Also why does it just ignore the sight radius and stuff. (i dont have any errors in my console)

Why is the ai shooting up
