Unreal Engine NPC Car Tutorial 

If you want to speed up the AI, you can set the gear with "Set Target Gear". Be sure that "Immediate" is true.

Thank you, you and another UE RU-vidr have made the last Audi video on my RU-vid Channel possible.

good work :) this guys work is solid .

Awesome Tutorial!!

You are great! This is exactly what I need.

Legend thankyou for this quick solution!

Wow, superb, thanks!

This worked! Oh lawd it worked.

Implemented - Thank you

thanks you help me alot!

Thanks for the tutorial not sure why this didn't pop up for you but I was getting access none errors following your guide so I had to do assign a value to Path variable. I used a get actor of class node to get the reference.

Thank you!

nice!

Great!

Hey Seredias. So i wanted to copy this blueprint into various different type of vehicles. And have the vehicles follow along 3 - 4 different paths like in your earlier traffic/change paths tutorial. I think you had an integar which allowed for selecting different paths in details panel. But this code doesn't give option/integer for multiple paths. I am just wondering how i can have the option to change it's path to different splines?

Thanks!

Thanks

Hi @seredias i dont understand the logic in the part where you mention find tangent closest to world location and then normalize why is that required ?

Hi!!! 2 questions I went through some of your videos on this topic and I realised that you (as well as several UE5 tutorialists) did a lot of Car AI stuff without utilising the AI behaviour tree and Blackboard systems found in UE5. I want to ask whether it was a creative choice or if there was a specific reason you used these methods over those. Is there a specific reason for it? Question 2 I tried with a first spline and it worked but steered too early before it got to the bend. I then deleted it and made another spline but the car ignored it and drives in circles (the active path is always set) and it ignores every spline i make Why is it doing this and can i fix it?

Great tutorial!!Please,make a turorial about How to make cruise control foe car in Unreal Engine 4🤙🏼

Ok, so this works great. But, if I spawn a car into the world, then give it the reference to the spline, and a Speed to start off at, it doesn't do anything. Any idea why? Steps the recreate issue... Set a Spawn Actor of Class (of type AI Car or whatever your vehicle is called) node on a Begin Play in another BP. Set the location to be at the start of the spline. Then set the Path Reference and Speed right after the Spawn node. The car will spawn in, but it won't move. I've done Print Strings to make sure it has the correct Path reference and Speed. It does, but still refuses to budge. Any clues to what I'm missing?

Hello, I'm on the same unreal version as the tutorial, however the "default" menu to select "Actor path" doesn't appear for me. Is there something I need to do to enable it? Followed every step verbatim. Edit: Managed to find it by opening the property matrix however when I try to select "path" it doesn't confirm my selection, any way to fix this?

Currently trying to make the same car made in this video spawn in and follow the path. I tried to follow one of your tutorials about car spawns but that was too complicated for the thing that I'm doing. Any advise?

Hi there @Seredias So everything worked until I placed "Path" blueprint on the world, and there is no spline points (spline points are visible in the Blueprint Editor). Any ideas how to fix that?

Hey! Is there anyway I can make the sportscar work in a custom map? I tried assigning it to player 0 but nothing happens when i try to play. Ue 5.1

I really like this video but I have a problem. I want to scale the car down to .05 but the problem is that when i run the program, the car flies above the ground. I can't seem to keep the car on the ground. it takes off and flies along the path of the spline. Help

Thank you for your nice Tutorials, I am since 1998 3d Artist in the automotive industry and since last year I try to learn unreal 5 after some years experience with unity. The blueprint thing seems to be very innovative, but in the beginning it's hard for me to understand this programmer logics. Your Tutorial is good, it runs exactly like your example now. So my question is, when I duplicate path and Ai car in the world brower, go get a second car that drive as on coming traffic in reverse direction. How can I do this, my second car everytime turns around on the second spline and drives in the same direction of the first car.

The Default category that has active path isn't in my details 1 menu? Has this changed for Unreal 5.1? Thanks!

Hi..Thank u For the Tutorial How Can I Stop The Car when the spline Point Ends

Hey there. I seem to have the same issue as a few others. I followed your tutorial exactly, and the car does not follow the spline. Just drives forward no steering. I am using one of the vehicles from the free market place selection (VehicleVarietyPack). And also I have indeed set the default to Path @4.44. Any ideas? Thanks alot for your tutorials btw!

Path Object type doesn't seem to exist in 5.3, any ideas what it might have been replaced by? Cheers!

i did exactly as shown in the video, very clear i wanna say! But i have an issue with my spline, the car will follow the path for like 5 meters and then it will start to do 360 degree turns lol any idea how to fix this? i'm on ue 5.3.2

Hey sir, do you know a way to make a car AI chase the player until it stops or obstructs it? Just like the police cars in Need for Speed monster Wanted.

Dear Seredias Do you know how can we get speed or acceleration of car during the game and save it every one second and then export it? In other words how we can get vehicle data and save it in data table I wish you had a video fir that

Hey Seredias, thank you for the great sharing , is this able to work in sequencer ?

What changes would i have to make to the stearing input to get the car to go backwards as it drives along the spline?

it's not taking a turn it is just going straight thereby not following the path. any idea why?

HELP!! It keeps stopping while running. (If you stop, the wheel doesn't rotate and goes forward.) If you stop again and start, it stops again as if it's under constraints. How can I solve it?

nice one, be nice to know how to make it so the ai knows how to brake before hitting corners

is there a way to set the active path through blueprints ?

My car keeps swerving side to side to stay on the path, it’s not really curvy but it still swerves.

How to set neutral gear position or clutch in unreal engine (Neutral such that the car will roll when in an inclined position) Thank you in Advance.

Can I create animations with this? Like for a short film

what's the Vehicle Movement Component?? I don't find is this

single car not problem but multi car problem automatic stop if any solution please tell me sir

seredis,sorry to border you again , i sue the sport car it works , but when i change to custom car , the rig and everything fine in the game mode, once i apply the step ,the car just stop and not moving at all in the simultiaon , any clue ? ? sorry to border

i have an issue. When my car turns it slips off the path and crashes into the wall, despite the fact that the spline is following the track. How do i fix it? SOLVED: There was not enough of a downward force on it. Multiplied downward force coefficient by 100

Can it stop and/or drive around obstacles in path GTA style?

This tutorial is great! I am encountering a very strange issue though, and for the life of me I cannot find what the error can be. I followed this tutorial twice for two separate projects, and the first one I had no issues. The second one, however, while the AI follows the path and steers beautifully, for some reason the car will just abruptly stop out of nowhere at random, and then proceed again a few seconds later. The AI blueprints are, minus some variable names, are identical between the two projects, and I confirmed my vehicle's settings are the same as what you have in the video (automatic transition, etc). So I'm at a bit of a loss as to what could possibly be causing the car to suddenly stop out of nowhere. I would've just reused the first project since it's working there, but it's a situation where while they both use vehicles, the games being made are so drastically different that it was easier to start from scratch than to copy the project and strip out the unnecessary parts. Tracking their variables with some debug commands and whatnot, the steering and throttle are appropriate being applied to the AI cars too. Like the throttle doesn't just become zero out of nowhere for example, even when they stop. Is this an issue you've encountered before, and if so, do you happen to have an idea of what the error could be?

how can I make the car to stop

hi in the end i can't find "Default> Active Path" can you help me? Blueprint Runtime Error: "Accessed None trying to read property ActivePath". Node: Return Node Graph: GetPath Function: Get Path Blueprint: carro-ai

My car has gone heywire. I dont know what it is following, but it is certainly not the spline. Need Help

How to make the car follow the same path in loop like on a race track

Hi bro. thank you for video.I have Question I done every thing seam this video but my car going revers. can you help me please how can I do for solve that?

What is the reason why this method does not work for vehicles that are not equipped with UE5 and can drive car resources....

I followed everythink as close as I could but the car is not following the spline. I am really stuck here. Can this happen because of anything specific?

Thanks for the tutorial, but I think you should explain a little bit, what are you actually doing and why, not just plant one node after another without any explanation of what it does. Especially for new users it would be much more helpful.

tell me how to get points for overtaking a car how it is implemented in traffic racer pls)

Finally made the move to UE5? Is it permanent?

Sir also want a tutorial on police car chasing please help

make sure u thumbs up! we need good coders on youtube.

Very nice tutorial. if I would for example duplicate your car and want to have both driving at the same time, and following different splines, could I just duplicate the spline actor and draw a different spline for that and point the second car to it? Because I tried and it doesn't work. Duplicating the AI_Car works fine. Just call it AI_Car_2 and it has all the set up work done in the Event Graph etc. But duplicating the Path actor didn't work. The AI_Car will follow Path no problems. But AI_Car_2 will not follow Path_2. What needs to be done? make the Path actor from scratch instead of duplicating? Because everything else is the same. if the solution is making the path actor again from scratch, why is that needed? Thanks!

the vehicle just goes straight does not turn. I am using chaos vehicle component as my vehicle is a tank.

i dont understand all think is perfect but ai car automatic stop few second later when we see car they automatic start when see ai car

Can you please make car damage tutorial?

gotta love when my ai car is redlining

Im tired ive done this 3 times flawless but when i try to make more than 1 path component for different cars of coarse only one ever shows up which is fucking stupid this is the dumbest engine ive ever used

Use Full Vedio

traffic master

The Car is driving in circles

bro my car rotates in its own place plzzz help

Can u do how to stop ai car?

@Seredias I really needed this! I have an issue though, I need the car/s to go much, much faster when I do so there they an issue going in a straight line and also sticking to the path is there a fix for this you can suggest? > ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Kwjf7M26eOk.html also; when I try to simulate instead of pressing play, the Ai car doesn't move do you know why and is there a fix for that also please?

Thanks!!!

Thanks
