For anyone having trouble getting it to bake your different zones, double check your sorting layers and z position on the transform. make sure z is 0 for all objects
By far the best tutorial to this topic. There is no offtopic, no hyperactive and stressfull voice, just getting straight to the point and showing what to do
Incredible tutorial, super helpful and easy to implement. I'm trying to allow the enemy to rotate while navigating. Whenever I try and make it rotate I made the updateRotation true, but then it allows rotation on all axis, only am looking for Z-Axis. Is there any way I can limit that rotation to the Z-axis only? Thanks again.
ths video is great and there are so little like this - thanx!!! i have small question -i am looking to fcreate the enemy going after the player but still stics to the walls - like a spider runing on ceiling floor and 90 degrees walls. but this video shoes the best and shortest route so he doesnt stick to the "floor in 2d like he stick to the floor when its in 3d navmesh - any way to make it stick to walls and floor?
If I set updateUpAxis to false, then the agent can't move upward in my scene view. But if I comment the line out, the rotation is set to -90 on the X axis (which renders the sprite invisible on the screen). For now I have the update function setting the rotation to 0/0/0, but then the agent is constantly moving on the Y axis (albeit very slowly). Yes, I have updateRotation set to false.
Just tested it on 2022.3.19f1 and still works. I was straggling for a while to make it bake properly. I was able to fix it by adjusting navigation options - especially the radius. I think my map was to small to work with default values set by default for "Humanoid" agent type. Anyway, thank you for the video!
Could this be implemented in a procedural tile-based level generation? Could the scripts be somehow applied to - for example - "Walkable" and "Obstacle" tagged tiles after they are generated?
overlaping walkable sprite on top of obstacle is not considered, in my case i have a ground and a big empty room, upon bake 2 navmashs created outer and inner, but when i overlap a walkable sprite on a part of wall it just dosnt considered walkable. can anyone show me how to?
Hey, when adding the components to my project I get 21 warnings like this: "Assets/NavMeshComponents/Editor/NavMeshSurfaceEditor.cs(80,13): warning CS0618: 'NavMeshVisualizationSettings.showNavigation' is obsolete: 'showNavigation is no longer supported and will be removed.'" Is this package still good to use, or do I need to resort to unitys own new AI navigation package? Any help would be appreciated, thank you.
Quick question. Navmesh Agents will over ride colliders that were not baked. They will literally walk through walls when they have a destination. how do I fix this problem?
Suppose you have a grid (it could be a TileMap2D) where the rule is that crossing diagonally has a cost of "3" and sides "2", plus your enemy has a maximum movement of "10". How to do it with NAvMeshPlus?
Having an error: "SetDestination" can only be called on an active agent that has been placed on a NavMesh. Do you have any ideas why my agent doesn't get registered on a navmesh.
[SerializeField] private NavMeshSurface navMeshSurface; private void Awake() { navMeshSurface = GetComponent(); } //and call this function when u need to bake it private void BakeNavMesh() { // Build the NavMesh navMeshSurface.BuildNavMesh(); }

for some reason when i click bake, the navmesh is not visible on the scene view i m using unity version 2021 EDIT: I had gizmos visibility toggled off lol
As far as I can find, no. I'm having the exact same issue. Originally I was going to use Unity's calculatepath method and just AddForce into the direction of the next path, however, navmeshplus does not seem compatible with that. The only other option left I've not tried is finding a way to use the agent with updateposition set to false, and seeing if that path works.
I don't know what you are doing wrong, it works for me as you can see in the tutorial :) Maybe join the discord and show what you are doing and I might be able to help
I added the navmesh surface to my level manager "public NavMeshSurface surface;" then I can call "surface.BuildNavMesh();" to build at the start of each level or if I shift the level mid gameplay. that basically runs the bake function. Note you need to include "using NavMeshPlus.Components;"
its not working . i use click to to move and when i click to move at random position then player is passing through the obtacles, even though obstacles are not walkable and in the scene they are also not blue .
thats very hard to say since there is so many different ways you could have developer your game :) maybe if you show me your code in the discord channel?@@MMonis-ge6lh

Hi. I've been struggling with navmesh for months. I have watched this video a dozen times. I cannot get it to work. I add the navigation surface and the navigation collect source2d. click rotate surface to XY and unlike you, after i press bake. nothing happens
This is a great tutorial, but when i arrive to the step of adding the ai navigation packege it wont appear. (if someone know how to solve it please tell me) :'(

Thank you! Yeah I felt that this was missing when I was looking for a tutorial on the subject :)
If you want to make the navigation mesh more dense, add "Window -> AI -> Navigation", adjust "Radius" and try Bake again.
this is so much better than A* thank you for this
Great tutorial man, you explained so well it was really easy for me to transfer the technique to a 2d tilemap.

What about Navigation Modifier Volumes? They seem to get ignored by the baking process.

Nevermind, I tried to include my own naming conventions already and messed something up along the way. It works now, thanks again! :D
hmmm didn't work for me says that "Failed to create agent because it is not close enough to the NavMesh"
What how do i fix this.
why does the compiler not enter _agent.SetDestination(hit.point); ?
Quick question. Navmesh Agents will over ride colliders that were not baked. They will literally walk through walls when they have a destination.
how do I fix this problem?
Navmesh repositions your objects in a static fashion. Use velocity to reposition your characters and it will respect the colliders.
Suppose you have a grid (it could be a TileMap2D) where the rule is that crossing diagonally has a cost of "3" and sides "2", plus your enemy has a maximum movement of "10". How to do it with NAvMeshPlus?
Having an error: "SetDestination" can only be called on an active agent that has been placed on a NavMesh. Do you have any ideas why my agent doesn't get registered on a navmesh.
UPD: Solved, the problem that my Nav Mesh Agent height was too low.
Thank you!
Thanks for this!!
Thanks for the video!
Is there a way to change the movement speed as I desire for each enemy?
My pleasure! You can change the "Speed" variable in the NavMeshAgent component
Hey, I was wondering if it was possible to bake the navmesh during runtime?

Urgent question. How do I bake the navigation Surface from the code? I've got a dynamic map and I cant figure it out
[SerializeField] private NavMeshSurface navMeshSurface;
private void Awake() {
navMeshSurface = GetComponent();

//and call this function when u need to bake it
private void BakeNavMesh() {
// Build the NavMesh
navMeshSurface.BuildNavMesh();

Is it possible to make multiple enemies come to the player and stand around the player, the enemies will avoid each other like they avoid obstacles?
Have you tried giving them the "Navigation modifier" component and set the override area to not walkable?
Waiting for next video
What would you like to see?
Hey, does this work for movable obstacles?
Hello, I'm not sure, I haven't tried it. I guess we would have to rebake alot for every move
Followed your tutorial but I don't know why I can't drag the player into the target input on the enemy object. Any recommendations? Thanks in advance
Make sure you have the Enemy script attached to the Enemy object before dragging :)
@@rootbindev Thanks for this quick reply but I think I had other issue. My enemy is a prefab but my reference object was not a prefab. Fixed it tho :D
@@kanoblack6179 im having the same problem. how did you fix it?
@@MrEthan. If one of the objects with the script attached is a prefab, both has to be prefabs

That's why your basics should be clear.

how can i make it move faster? ty!
Thanks )))
thank you
When you play, the z-value of the enemy's transform position changes even though it is 2D. This is also visible in the video.
Oh, I haven't noticed! Nice that you found it and told me about it
When i add nav surface it says Object reference not set to an instance of an object
Try restarting unity
my game objects disappear when i add the nav mesh agent component to them. i changed their order in layer but they still wont appear
Try checking your gameobjects Z position value, is that always set to zero when you play?
for some reason my gameObjects z position always goes to -1.169839, any idea why?
Have you tried this :
void Start()
{
navMeshAgent = GetComponent();
navMeshAgent.updateRotation = false;
navMeshAgent.updateUpAxis=false;
}
doesn't work in 2D. help, what am I doing wrong? I tried to repeat the tutorial in different versions, the grid is not being built
