Unity 2D Tutorial How To Make Enemy Walk And Follow Along The Path Using Simple C# Script In a Game

[@otrocanalmas8096]

This is exactly what i want for a long time.... quick and usefull tutorials.. i've seen this in 24 minutes and even 45 minutes to explain this :) thank you

[@AlexanderZotov]

Happy to help. Thanks for your feedback!

[@Searwitch]

Others would've milked this for 10-20 minutes. Thank you very much!

[@random_precision_software]

I love these quick and lots of tutorials, it's about time someone done a video everyday, and the content is what everybody wants. 👌😀👍

[@Worlnof]

I really do LOVE you! You are my hero, I had to search soooo long to find someone explaining this to me

[@bren.n.z.]

I have been searching for a tutorial like this for days and this is exactly I need. Awesome video

[@01dragonix]

in case that is not working for you check that the Z position is the same on the Enemy and the Point

[@leonholli7281]

Saved my day

[@anonymy834]

thank you! you saved my day! had been confused for ages why my sprite did not work. It came to my mind that someone in the comment area could comment on this. So I reviewed the comments one by one. You saved my day!

To add rotation if you use car as a gameobject: if (waypointIndex != waypoints.Length) { Vector3 targetInVec3 = new Vector3(waypoints[waypointIndex].transform.position.x, waypoints[waypointIndex].transform.position.y, 0f); Vector3 direction2 = targetInVec3 - transform.position; float angle = Mathf.Atan2(direction2.y, direction2.x) * Mathf.Rad2Deg - 90; Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward); transform.rotation = rotation; transform.position = Vector3.MoveTowards(transform.position, waypoints[waypointIndex].transform.position, movespeed * Time.deltaTime);

thanks :)

[@racmanov]

works like a charm. had to work around some stuff coz i do 3d and use rigidbodies. But now it works flawlessly. ty

[@michalstanislawbun5443]

everyday a new and useful lesson! thanks a lot

[@rjsiii3]

One of those videos that takes something that seemed impossibly confusing and makes it feel like "duh well of course". Great job and i appreciate the shortness of the video, as much as the games of the idea. Liked and subscribed

[@ilovecode3727]

so fast and clear. THX!!

[@phpickles]

Ty!!! (if is not working for you make sure your z coordinates on every waypoint is set to 0).

[@beaverjoe9171]

So Effective and convenient way for me! THANKS!

[@lazzzzz_exe]

UnassignedReferenceException: The variable waypoints of FollowThePath has not been assigned. You probably need to assign the waypoints variable of the FollowThePath script in the inspector. help pls!!

[@Parisphotogram96]

thanks bro , i love what you sharing with us

Happy to help

That’s how they do Sonic. You enter the loop, it enters a path, and you exit the loop.

[@liudaxun]

Any idea why there's an error Index was outside the bounds of the array? when I tried running

[@apoleyta9760]

I don't know why but ıt doesn't work for my game. I have done whatever you said. But my enemy doesn't walk. Just pop ups in the first point because of the codeline in the Start method

[@geeayarrwhy]

Did you find out why? I'm having the same issue. :/

[@AlexanderZotov]

Check out Z axis value. It should be zero.

[@griseldapozo1405]

@@geeayarrwhy I had the same issue, had all my Z's on 0, but I had my waypoints in a container and that had the Z on a different value, changed that and works now.

[@vakarisgasiunas1867]

Hello, new to unity, is the any way to make it, that the enemy would start over after reaching the last checkpoint (for example: Waypoint 1 -> Waypoint 2 -> Waypoint 3 -> Waypoint 1 -> Waypoint 2 -> Waypoint 3...

I only have one waypoint, because the enemy is simply walking straight across the screen. How do I make it so that they aren't instantly going to the waypoint but instead more slowly going to it?

[@itsdonix]

how can i make it loop the movement path?

[@marvicbautista4583]

Hi again, when i make my enemy as a prefab a cant put the way points on the inspector i dont know what happen.

[@Mamaco915]

Nice tutorial but for some reason the square doesnt move what is the problem ?

[@SMGtk]

what if there are two options at a point? How will the object make the decision randomly

[@mobilemon5032]

The object is moving for me but it moves really slow. I followed the tutorial exactly, what's wrong?

[@blackstarstudios920]

Its not letting me add my waypoints into the slot. Help!

[@jamesesa501]

why my Enemy is not moving anymore when I change the enemy to another place?

[@gavinckw97]

Hello there! May i know how do i make the object to rotate based on the path?

[@IROC___Jeff]

This only worked once for me. I remade my enemy and followed the video again and my new enemy just starts at the first waypoint and just sits there. No movement regardless the speed i set. The script was copied and pasted so there are no errors from my end. Any ideas?

[@AlexanderZotov]

Check Z coordinate. It should be zero.

[@cristianquiroz4200]

For some reason the comparison between Vector3 fails. try this: private float distancia; private void Move() { if (waypointIndex

[@howtogamedev_]

it was really helpful, thank you so much

[@marvicbautista4583]

my sprite only goes to the first point and don't go to the next one I don't know whats the problem. I hope I can find some ways to fix this. Thankyou

[@Ghoqable]

in Unity 2d can you make a tutorial where a character moves randomly but doesn't go through certain objects like walls? Without navmesh?

[@sife-i9n]

it's just follow one waypoint than stops

[@Chief-wx1fj]

Enemy tutorials make me happy

[@lordtoby7454]

This helped me very much A quick question: I want to make an enemy repeat the path he follows over and over. Do I just wrap the code into a loop?

[@petipois28]

If (waypoint == waypoint. Length - 1) Waypoint index = 0 This way it will start over again

！！！！！My pleasure! Hopes I can learn more from you!

[@random_precision_software]

Can you Change this so the player draws as line then an object follows along that line?

[@dragontailsb1971]

if it isn't working for you, change "transform.position = Vector2.MoveTowards..." to "transform.position = Vector3.MoveTowards..."

[@sumkid9263]

clutch, this is the only thing that worked

Thank you so much. Couldn’t figure out why z axis was changing even tho it was set to zero 😭

[@dimitrishow_D]

I tried this and tried to spawn a new enemy after it dies.. But the enemy prefab then doesnt have the waypoints anymore.. I tried adding the wavepoints to the prefab in prefab folder but that doesnt work i can only add them when is in hiërarchie.. Do you know how i can solve this... Have a enemy have waypoints and being able to spawn it?

Sir when I try to make this enemy as a prefabs the the element in way points are not there why that happened

[@JongHyunSM]

can you explain how to face idle with 8 directions after follow the path?

[@siscoye9454]

Had it working once or twice, went back to use the script, and again it wont pass waypoint one , no errors :(:(:(

[@davidlandenkarlsson9983]

@SuperNinja Had the same issue as the guy above. Tried putting the if statement above the other but it yielded the same result. Thing is that it works fin for one of my enemies, but if I change waypoint (as is the case for my second enemy) it just stops working. Both enemies and paths are put up the same way, but one enemy works, not the other.

Thank you very much! Very good and usefull :) I have one question. You have a very interesting tutorial with dice. And I'm tring to use it. For example, you drop the dice, got a number, and how to make your character go that number waypoints?

[@siscoye9454]

Some reason mine never goes past waypoint one Followed the tut to a TEEE , no errors in code, waypoints in inspector set up :(

didnt put capital W on waypoints object :( spent 5 hours doing it over n over lol

[@sharif47]

I need some help with adding some features to this. 1. I'm working on a 3D environment and I want the y-axis value to be determined by gravity. 2. I'm working on a car AI. So, whenever it faces a turn, it should at least rotate in order to make the turning look believable. Because the path is created by finding the shortest path based on a grid system, the adjacent points are the center of two adjacent squares in the grid. So, the distance between two adjacent points are either 1(for horizontal/vertical) or √2 (for diagonal). See if this info can help in making easier code for rotating.

Hi! thank you, i combined it with a scriptable object in order to make it portable and more flexible.

This is great. Can you show how you would set this up for 2 different paths and have it randomly choose which path to take?

[@suryanshrana838]

you could give it two lists and make randomly choose which list of waypoints its going to follow
