Hello I have a problem at Min_11:50. how do you do the copying, i've tried it a few times now. And I don't get a copy that is visible. So I can just copy it, it doesn't stay displayed. Whenever I want to create a new street section, the previous one disappears and is no longer displayed to me. I'm probably missing a checkmark somewhere that I didn't check. So I could have 20 street segments and copy and do but they only show up when I click on them one by one. can you help me with that.?The video is so well explained and I am stuck on a small part.😭😭😭😭😭

I don't know how to say what I feel now, sad or glad... That's because I got the exactly same problem I had with the MassCrowdAI. Some of cars run around a couple of second and stop, and others don't move from the beginning. I don't know if this symptom results in the same cause to what I got with the MassCrowdAI, but I do really hope it does. This time, I followed your tutorial in completely new project, not in my project.
I can't confirm this fully but I think the amount of Zone Shapes might contribute to it. I was using one long zone shape in place of the three. Now if only I could get my cars to stop randomly full stopping.
When I drag the zone shape to the landscape and click the landscape the zoneshape disappears. Also when I copy the zone shape and select it the first zone shape disappears. Do you know the reason?
I know why, go to the top of the screen and click Show then go down to Developer then mark Zonegraph, new go back and click Show again and mark Navigation

I do have one issue with it though, I added 2 car agents for different cars and everything worked perfectly, but adding a third car agent doesn't work for some reason.

However, adding the cars from the marketplace does not work in 5.1 as the bundle is made for 5.0. Since i am not the biggest hero in UE, I do not really know, which part of my city sample to export to for sure have all the cars and features.

hello when I create my cars they follow zone,but they can move underground，if zone a little bit underground. I added a collision to the car. how can I do.Thanks
@@viperdkue5 So, I did everything as far as you did. With the difference that I don't have to do every single zone now. It also works, so to speak. the cars drive normally, there is only one that drives and I can then set how many should drive it. that also works perfectly the problem I have is that the cars only drive one lap and then always stop at the starting point or rather at the destination. if you tell me where the problem is that they only drive one lap, I'm really happy about it.mfg
@@81Nemessis I know exactly why, 1 Zoneshape can't connect to it self, so you need to add at lest 1 more , also only 4-5 cars can be on 1 zone at a time , so if you add more short zones you can have more car's driving around.. Good luck :)

@@viperdkue5 I see in the ZoneShape you can assign a tag. However in the MassSpawner there is no place to assign a tag. Is there a way to assign a tag to the mass spawner?
ai.traffic.parallelize not found.I modified defaultrngine.ini,added ai.traffic.parallelize=0,it crashed too.Any other solution?
Thanks for tutorial, its really helpful, but at a great distance, cars disappear, how can this problem be solved?
Thanks for linking the Plugins also for UE 5.1 - This made me cool down when I did not find one of them in my 5.1 ready city sample project.
However, adding the cars from the marketplace does not work in 5.1 as the bundle is made for 5.0. Since i am not the biggest hero in UE, I do not really know, which part of my city sample to export to for sure have all the cars and features. Can you give me a hint on what to migrate or shall I start with a clean 5.0 project and then lift it to 5.1 ?
You are welcome.. you can use the cars from the marketplace, just download them as 5.0 and they get added to your project.
How to control speed and other aspects of vehicles
Speed is in the MassEntityConfigDataAsset and looks is in the ActorBlueprint
@@viperdkue5 omg thanks for quick reply! its like some premium service lol
@@samvortex4136 No problem, hope you got it working like you want it too :)
@@viperdkue5 any idea how to access speed for vehicle from actor blueprint,
@@samvortex4136 You can only access MassAI from C++ atm, But im working on plugin for Blueprint access... You can give Zoneshapes speed limitations, but I dont remember how .. If you just want to know the speed of the vehicle and not set it, you can use Actor velocity.lengthXY
Anyone has a tip, on how to.. Remove a car from the mass ai on runtime and replace by regular vehicle blueprint?
Like, walking up to a slow driving car, press a button and it becomes a regular ai-vehicles-BP..
Trying to implement vehicle stealing mechanics, but keep the ai vehicles in mass, to have better performance
You can try with a collision box and in overlap begin do the replace
@@viperdkue5 @Viperdk UE5 thanks for the quick response.. And than, if following your example.. I'd just create that enter overlap event in the event graph of the lowrescar itself?
Will that just replace only 1 instance of that vehicle and not mess up the other mass ai vehicles?
hello when I create my cars they follow zone,but they can move underground，if zone a little bit underground. I added a collision to the car. how can I do.Thanks
Do you want it to go under ground or you dont want it too?
I don't want the car going underground with the zone
Hey any idea on how i can randomize cars model ?
Actually they created a mass agent for every vehicles :d
So I've got it 50 times now, I can't get it right. Is there a possibility that you make a new video. One that's on the latest strant.
Im sorry to hear that, what exactly is the problem you are facing ?
No new update's that will break it.
@@viperdkue5 So, I did everything as far as you did. With the difference that I don't have to do every single zone now. It also works, so to speak. the cars drive normally, there is only one that drives and I can then set how many should drive it. that also works perfectly the problem I have is that the cars only drive one lap and then always stop at the starting point or rather at the destination. if you tell me where the problem is that they only drive one lap, I'm really happy about it.mfg
@@81Nemessis I know exactly why, 1 Zoneshape can't connect to it self, so you need to add at lest 1 more , also only 4-5 cars can be on 1 zone at a time , so if you add more short zones you can have more car's driving around.. Good luck :)
@@viperdkue5 I'll try to add another zone. And will then report whether it worked, thanks for the quick reply.😍👍
hi guys。Is there a UE5.2 tutorial for this method? I followed the steps in the video in 5.2. But when I start running it, it just crashes
Hi, I gave up trying to get it working on 5.2, too many bugs, 5.3 is a lot better..
Thank you very much for this tutorial, Can you come up with a tutorial on a homemade vehicle? Looking forward to your answer
Hello, you can just change the mesh to any thing you want riged or static.
@@viperdkue5 Thanks for the reply ，The Wheels on the right side of the car spin backwards but the ones on the left side work fine， Is there any fix for this?
I'm using 5.2.1 ，Awesome Videos by the way, they help me a lot!!!
I encountered a remote view of the car, the project will crash
Hi, I'm using UE5 5.3.2. There is no Anime To Texture folder in the city sample file. I'm writing traffic, I can't find the ai.traffic.parallelize, it doesn't seem. I would be glad if you could help
facing the same issue and the game crashes when played. have you found any workaround on your own? or maybe a solution?
Sorry I couldn't find a solution@@ryanq7518
I haven't looked at 5.3 yet, but the "ai.traffic.parallelize" command have been removed
@@viperdkue5 hello viper. do you have any guide on how to create the intersections and traffic light system like the City Sample project?
Excuse me, please question, why did my car stop after running for a while?
How many vehicles do you spawn and how many ZoneShapes do you have ?
Try and type "MassTraffic.DebugShouldStop 2" in the Command Console then open Visual Logger and hit record, it will tell you why they stop
@@viperdkue5 thank you reply quickly, I fixed this problem
@@viperdkue5 thank U replay, I recreate the project and do same it , its ok, not error
@@viperdkue5Hi brother, the visual logger says “NOROOM“ how do i fix that ?
@@rahulbhardwaj3694 @15:04 The problem I am facing is that once the cars spawn in the scene on the zone shapes and after moving a certain distance(very less) they automatically stop and I can see " No room" marked on the top of the stopped cars! were u able to resolve it? . Have been stuck with this issue since weeks and have created the exact same path using zone shapes as shown here! 🙏🙏
can i use this plugin my game
Wow.. impressive
Have you ever had an instance where the cars spawn but are not moving?
Only when I try and use a Highres Vehicle(wheeled chaos vehicle), not with the Lowres(Actor)... I did do this project a couple of times from scratch
@@viperdkue5 Ill go through the steps again. Thank you for doing this and teaching me some of the new content. It's great 👍

Hello friends, have you found it?
@@yingjunjin i tried but car are moving only straight and the lowrescar on that video arent moving
Sorry, I don't understand what you mean, I see that his path in the video is a closed-loop circle, now the AI will stop when it travels to the place where the path connects, and there will be individual mistakes when I make the crowd, and individual characters will stay where the paths connect, I am very confused...
Hello, Two questions. Is there a way to have the AI change there animation to make a step up on the sidewalk curb and when they bump up to each other?
Yes, I'm going to release a video soon with animation blueprint, but the bump reaction you can implement with contextual animation, Mass got a task for it in the state tree.

Hello, where can I change the speed of the vehicle?
In project settings under Mass
@@viperdkue5 Thank you very much for your reply, I have found it. Is there another question I can ask you? It is the crowds or vehicles generated by Mass. If the parameters are the same, is there any way to make them the same every time they run.
the wheels are not rotating anyone have the same problem
can not package
Would this work in ALS
ALS, the character movement system ? If so I think it's just up to you to make the animation blueprint do its thing..
@@viperdkue5 awesome thank you
police chasing system?
Is it in the demo ?
Hello, I have watched your video no less than 30 times and still cannot generate a car. I'm working with the latest version 5.2.1, will you make a new video on the new version? Thanks for your help.
Thank you so much! Epic launcher doesn't let me download the city sample project on mac, and large size and shader count would be cumbersome.
Too bad it takes 8 hours to just create a project in UE5...
Not sure what you mean ?
Hello. I'm trying to make cars and people move at the same time, but as soon as I do, UE5 crashes. Separately, they work fine. But together, they don't want to work. I've done everything strictly according to the tutorials. What could be wrong?
The Traffic plugin is kinda buged, but if you run the console command "ai.traffic.parallelize 0" before you play, it fixed it for me.
