New AI Navigation in Unity

[@CraveMayhem]

You are a legend. I have not used unity in 2 years and I'm trying to make a new game for the first time since then and it was driving me nuts trying to set up nav mesh and all of the guides even on unity's official website were not telling me where to find it. Thank you so much!

Thank you so much. I'm in a game design college course and the tutorials all still used the old navigation window for navmesh.

The new AI navigation system look quite simple and useful！ Thank U.

[@CreativeMediaTutorials]

Glad it was helpful!

[@Novica89]

Great explanation ! What I'm wondering and what I've noticed is that NavMesh Surface, when baking, weirdly "raises" the height of the walkable surface for some objects in the scene (like a sphere which I added to represent an enemy my player walks towards). What happens is that my player goes to the enemy sphere and then "climbs on top" of it's head

[@CreativeMediaTutorials]

This is the step height of the nav mesh agent. Try lowering that and it fixes the navmesh covering items that are low to the ground

[@lemetamax]

Very nice video man! Any ideas on how to prevent the agents from clustering together and walking all over each other?

[@CreativeMediaTutorials]

The navmesh agents have an avoidance that should prevent them from walking into each other. By default this is set to 50 for all agents. I sometimes make this a random amount using script, so that some agents can barrel through others, moving them out of the way to add extra interest.

[@lemetamax]

@@CreativeMediaTutorials But this system isn't using a nav mesh agent. Navmesh agents are not supported by DOTS at all. I want a way to achieve dynamic avoidance without using a hybrid approach. Basically, the entities won't overlap each other when traversing through a location.

Hi, I'm creating a game on Unity and I'm having problems with AI navigation. I have to do a chase between a bot with a target enemy and a prefab with a target player or the one who plays and I'm trying to use navigation to optimize everything but I can't do it. Can you help me??

[@a3dadventure79]

thx for your hard work man! v appreciated

[@CreativeMediaTutorials]

I appreciate that!

[@odo432]

I'm a little confused. Apart from a few minor changes, it's almost exactly the same as the old AI Navigation. What exactly has improved so much that they decided to make it a package instead of updating the built-in one?

[@CreativeMediaTutorials]

It's only a minor change, however, now multiple navmeshes can be created in a scene instead of just one, so you can have multiple agents of different size taking different paths

[@PG13park]

Is it better than A* Pathfinding now?

[@CreativeMediaTutorials]

@@PG13park It's roughly the same as it was before, only now you can have multiple navmeshes in the same scene that target different AI agents

[@odo432]

@@PG13park No. If all you want is a simple pathfinding asset then Unity's is more than capable of providing that for you and saving you $100. But if you want more complex pathfinding that has a lot more features and capabilities then you'll still need something like A* Pathfinding or similar alternatives.

The system for randomisation is exactly the same with the newer AI system as it was with the older AI system, so the code in the horror course will work exactly the same, however, now you can give each AI enemy, or zombie a different sized Nav agent if you want them to take different routes to the target points

[@thenukdevendra1902]

Anyone that has an issue with their AI maybe like not walking constantly, and just randomly pausing. I was making the AI follow the player using the "SetDestination" method, and that's how I did it before, but now it just stuffs it up, gotta use "Destination" and straight up set it like that.

[@CreativeMediaTutorials]

This is the most basic setup I use in this video, but it can be customized to make it much more realistic, even including some fuzzy logic so the character starts to think for itself. I cover this in my horror survival game course.

[@jessyjdirado]

This is by far the best tutorial I have seen thus far on the recent NavMesh system changes. I am having some different outcomes when it comes to the characters and the baking process. I don't seem to have them cut into the NavMesh like yours do. Also, and I'm assuming this is the same issue as the previous issue, my Modifier doesn't cut out any NavMesh either. Do you know what's going on? (Yes, I am an amateur)

[@CreativeMediaTutorials]

Thanks, glad it helps. Which version of Unity are you using? Check to make sure that all objects are touching the ground. If there are above the ground they won't be cut out of the navmesh. I am planning on making a more complex tutorial for the new AI navigation system so I'll double check these issues when I do that and post here on my channel

[@jessyjdirado]

​ @CreativeMediaTutorials Thanks for reaching out so quickly. I am using version 2022.3.5f1. However I know for a fact they are touching it and so is the Modifier but I will try lowering them into the ground a little. I thought maybe one of the options need to be changed in order for the baking to look for the capsule but my "walls" are working as intended. Edit: it is working now, I failed to select the correct agent type on the NavMeshSurface. My mistake!

[@skie1978]

The NavMesh surface bake does not seems to recognize painted trees as obstacle?

[@CreativeMediaTutorials]

That's right, this might be something that will be fixed in newer updates. For now you can still use Navigation (obsolete), which is the older version of the AI navmesh to bake a navmesh just for the terrain. This will carve holes for trees. Then when baking a a navmesh for other objects, switch off the terrain and it will bake a navmesh for all other objects. You can now have multiple navmeshes in one scene

[@Eculeus007]

Your trees needs the component NavMeshObstacle, Carve on, for cutting the surface.

Thank you so much! But I have a question...If I wish the enemy to follow the player only within a certain range, how would I do it? I tried if (Vector3.Distance(enemy.transform.position, player.position)

[@CreativeMediaTutorials]

I would do it in a 2 step system. First store the value of the Vector3 distance in a float variable. Then do an if statement checking if the new distance variable is less than a certain distance, after which, inside that if statement set the destination to the player. Don't forget to also do an else afterwards which either stops the nav agent or sets an alternate destination, otherwise you won't notice a difference

You can add another navmesh surface, but this time make the default area not walkable. Then switch off everything except the walls in the hierarchy and bake. It will now ensure the nav mesh on top of walls is not walkable. See 5.10 for multiple nav mesh surfaces

@@CreativeMediaTutorials Gotcha. You wouldn't happen to know how to make agents path around other agents by any chance would you? I tried adding obstacles to units, but that doesn't work out so well. Either way, appreciate your response and hope you have a good one.

[@CreativeMediaTutorials]

The NavMeshAgent automatically gets agents to avoid each other and move around each other. You can use the avoidance in the NavMeshAgent. It is set to 50 by default. The smaller the number the higher the priority. So an agent with 10 will make others move out of their way, but an agent with a priority of 1 will easily move another with 10 out of their way.

I tried doing what did. However, i keep getting errors. Did you ever get errors and if so could u help me.

[@CreativeMediaTutorials]

What errors are you getting?

Hello. I don't know why my previous comment go deleted so I will post it again. I tried your method but it did not work for me. I had to download from the github repo and drag in the Navmesh components and use their methods in order for it to work. My project is in 2D. does that make a difference?

[@CreativeMediaTutorials]

Hi, I've not tried it in a 2D project. Good to know it works from the github. The documentation for the new AI navigation package can be found here: docs.unity3d.com/Packages/com.unity.ai.navigation@2.0/manual/index.html

Hello, how do i prevent my player character from moving out of bounds

[@CreativeMediaTutorials]

This is just a simple example, so in this case it would just be clicking in the blue section. However, in more complex projects you would most likely have a raycast to detect when you are clicking within bounds allowing you to click there, and not allowing you to click when out of bounds. I cover raycast terrain clicking to move players in my Create an RPG Game course on Udemy.

but when i opened the paackage manager, i still cant see the ai navigatiyon, even if i search its name.. What can i do

[@CreativeMediaTutorials]

Ensure you select Unity registry from the drop down list at the top left. This displays all Unity packages available to download in alphabetical order.

[@jacksonsegala472]

Still can't see the Ai Animation ):@@CreativeMediaTutorials

[@CreativeMediaTutorials]

Do you mean the AI Navigation package in the package manager, or the AI character's movement (animation) in the scene?
