Question how to check if player is standing on a walkable part of a navmesh?

i need help, im trying to make the ground check in my fps with navmesh bc physics.checksphere doesnt work and neither does raycast, help

how do i check if the player is standing on a part of the navmesh that you can walk on? here is my code rn

Code (CSharp):

1. NavMeshHit hit;
2.             if (NavMesh.Raycast(groundCheck.position, Vector3.up * -1, out hit, NavMesh.GetAreaFromName("Walkable")))
3.             {
4.                 canJump = true;
5.             }

 

https://docs.unity3d.com/ScriptReference/AI.NavMesh.SamplePosition.html

 

https://docs.unity3d.com/ScriptReference/AI.NavMeshAgent-isOnNavMesh.html

 

I don't believe this will tell you if the Agent is standing on the NavMesh, only if it's bound to one.

 

It's what I use to check if my agent is positioned on a navmesh. The agent won't bind to the navmesh if it isn't close enough to it.

 

Interesting, does it unbind if the agent is forced off of the NavMesh? I haven't experimented enough with them to know the details.

 

Yes.

 

Also, NavMesh.SamplePosition won't as such just tell if your agent is over a navmesh at its current position, it will find the closest point on the navmesh within a given radius of the position supplied or return false if nothing in range.

 

i am not trying to use this for an agent, i am trying to use this for my player as a ground check

 

i wrote this,

Code (CSharp):

1. NavMeshHit hit;
2.             if (NavMesh.SamplePosition(groundCheck.position, out hit, 0.1f, NavMesh.GetAreaFromName("Walkable")))
3.             {
4.                 canJump = true;
5.             }

but its returning as false...

 

Change `NavMesh.GetAreaFromName("Walkable")` to `1 << NavMesh.GetAreaFromName("Walkable")`

 

dont necro

 

Do you got any solution?

 

I'm attempting to do something similar were you ever able to determine if a position was within a specific navmesh mask?

 

Thanks Yatyricky, much appreciated your solution.

Code example:

public Vector3 walkPoint;
public bool walkPointSet;
public float walkPointRange;

public void SearchWalkPoint()
{
float randomZ = Random.Range(-walkPointRange, walkPointRange);
float randomX = Random.Range(-walkPointRange, walkPointRange);
walkPoint = new Vector3(transform.position.x + randomX, transform.position.y, transform.position.z + randomZ);

NavMeshHit hit;
if (NavMesh.SamplePosition(walkPoint, out hit, 0.1f, 1 << NavMesh.GetAreaFromName("Walkable")))
{ walkPointSet = true;}
}
