Navmesh for Random Generated Maze

Hey!
Iam currently trying to do a simple maze Runner and using navmeshes for the movement. so a simple maze part looks like this:

and in this are 3 child gameobjects with each a navmeshobstacle(carved) on it

my scene looks like this:


when the game starts, a simple maze gets generated:

when i click nearby my player, he moves to the destinated point. but as soon as i click a little bit further away, he tries to run threw the wall and never reaches his destination. which looks like this in the editor mode:


ingame it looks like this:

sadly my gif-grabbing program doesent record clicks but on the gif above i am clicking pretty much all the time. and as you can see, the ball/player is moving when i click nearby, but as soon as i click on the lower right, he ignores it.

what could cause this behavior? did i missed something? if you need more screenshots, just let me know
ps: when the scene is empty, i can move all over the place, so this is working. here also some screens of my navmesh agent setting and the navmesh obstacle settings:

 

I dont like to do this but:
*bump* still need help :/

 

Try Obstacle Avoidance Quality to high quality ..

Also add this script to the ball so you can see the path generated .. the target will be the mouse click position.

Script supplied by Jakob_Unity

Code (CSharp):

1. //CalculatePathTest.cs
2. using UnityEngine;
3. [ExecuteInEditMode]
4. public class CalculatePathTest : MonoBehaviour {
5.     public Transform target;
6.     void OnDrawGizmos () {
7.         if (target == null) return;
8.        
9.         var path = new NavMeshPath();
10.         NavMesh.CalculatePath (transform.position, target.position, NavMesh.AllAreas, path);
11.        
12.         Gizmos.color = Color.red;
13.         Gizmos.DrawRay (transform.position, Vector3.up);
14.         Gizmos.DrawRay (target.transform.position, Vector3.up);
15.         Gizmos.color = Color.green;
16.         var offset = 0.2f * Vector3.up;
17.         for (int i = 1; i < path.corners.Length; ++i)
18.             Gizmos.DrawLine (path.corners[i-1] + offset, path.corners[i] + offset);
19.     }
20. }

 

thanks, but i got two error on line 10

Code (CSharp):

1. NavMesh.CalculatePath (transform.position, target.position, NavMesh.AllAreas, path);

NavMesh does contain a definition for "CalculatePath"
and
NavMesh does contain a definition for "AllAreas"

 

so i found this code here in the interwebs:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PathUtils : MonoBehaviour {
5.     private NavMeshAgent agent;
6.     private Color c = Color.white;
7.     public void Start() {
8.         agent = gameObject.GetComponent<NavMeshAgent> ();
9.     }
10.    
11.     public void Update() {
12.         DrawPath (agent.path);
13.     }
14.    
15.     void DrawPath(NavMeshPath path) {
16.         if (path.corners.Length < 2)
17.             return;
18.         switch (path.status) {
19.         case NavMeshPathStatus.PathComplete:
20.             c = Color.white;
21.             break;
22.         case NavMeshPathStatus.PathInvalid:
23.             c = Color.red;
24.             break;
25.         case NavMeshPathStatus.PathPartial:
26.             c = Color.yellow;
27.             break;
28.         }
29.        
30.         Vector3 previousCorner = path.corners[0];
31.        
32.         int i = 1;
33.         while (i < path.corners.Length) {
34.             Vector3 currentCorner = path.corners[i];
35.             Debug.DrawLine(previousCorner, currentCorner, c);
36.             previousCorner = currentCorner;
37.             i++;
38.         }
39.        
40.     }
41. }

and i think its doing the same as you code at least it draws a line and show me the path, i also set Obstacle Avoidance Quality to high quality. And, i kicked out the random generated part for the beginning. so the maze looks every time the same:


but still, the agent is not able to find his end destination. he somehow stucks in the wall at some point.

 

Try upping the size of the Agent Radius in the bake settings looks like not enough gap around the edge of the maze walls ..

 

still no success :/




it somehow always stuck at the same spot.
with radius 2 it also stops there.

 

Have you a rigid body on the ball? if so remove it and try that.

 

no, just my line navmesh agent and my navmesh script

Code (CSharp):

1. using UnityEngine;
2.  
3. public class NavMesh : MonoBehaviour {
4.     NavMeshAgent agent;
5.    
6.     void Start() {
7.         agent = GetComponent<NavMeshAgent>();
8.     }
9.    
10.     void Update() {
11.         if (Input.GetMouseButtonDown(0)) {
12.             RaycastHit hit;
13.            
14.             if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hit, 100)) {
15.                 agent.destination = hit.point;
16.             }
17.         }
18.     }
19. }
20.  

 

ahh, damn, there where some random navmesh obstacles in my scene which i didnt removed and they where on top of the maze. so stupid! but thanks for your help!
