I was planning on making enemies for my first game very soon, this came at the perfect time thank you!❤

For those of you having issues, try increasing the float in lines 35 and 40 to a larger number, you may just not be getting close enough to each point. You can control this with a float in your inspector for quick testing :)

[madretzlpiano]

absolutely great video! I just recently started leaning how to program (it was actually last weekend) and I must say: you explained everything very good and made it simple, so that even a beginner like me could easily understand it!

[Haffey.z]

thank you so much for this script. I modified it a lot, so when the enemy touches the player, it plays an attack animation that kills the player if the sword touches him, and after the attack, the enemy starts walking again.

remember to use composite collider if u are using a tilemap

[ChrismisHere]

Yesh! it worked, thank you so much for the tutorial :DD

[pureegaming]

thanks! this helped me do something i have wanted to do for a long time!

[gzerem]

Thanks a lot man, you really saved my timed Project, lots of love <3

To those who want to add a flip onto their sprite, add this bit of code to your first "If" and "Else" statement.

transform.localScale = new Vector3(-1, 1, 1);
transform.localScale = new Vector3(1, 1, 1);

Put it above your "rb.Velocity" code. If your sprite goes backwards then just flip the -1 to the other statement

Hi thank you so much for the help it worked for my game! I would love to see a video where you explain how to make the enemies idle for some seconds then move again though if it's possible sometime! Thanks for this brilliant video tutorial!

[valonyaver]

for some reason the if (currentpoint == point.transform) is not working correctly at all. I fixed this by making the speed switch direction in the second set of ifs (the ones that check the distance) and always have the velocity at speed.

The caracter doesn't stop at point B and I don't know why because I did everything coorectly. Can someone help me pls ?

[ilya_rusin]

What do I do if I want to add 2 and more patrolling enemies? Code works only for one enemy. Do I need to add a different script for each new enemy?

[firewarrior]

I copied this code minus the animation related things on unity, and all it does is make my enemy move until it hits a 2D box collider. Are the anim codes necessary even if you don't have animation frames yet?

[mohsen]

hey, the code works but I have the following Issue: If I set let's say the enemy as a parent Object and move the points under it, the code stops working and it just moves past the points

[SixFlickz]

ia nayone could help i got to the stage before flipping the enemy but my character still walks off the edge any fixes?

[SLLicant]

Life saver, I was doing it by have two trigger blocks at the end and when it enters the trigger block it reverses the direction

[skiwii]

Why does mine randomly stop after turning? After if give it a push with my player it starts moving again tho

[xonestly]

Very good tutorial! works good, i wonder if there is a way to make it so that the enemy can jump up a little step if needed so it can patrol larger area
