Bug: AC.NavigationEngine_PolygonCollider

Sometimes when I click on a hotspot I get this error and afterwards I can't move the player anymore.

It depends where I stand in the room.

IndexOutOfRangeException: Array index is out of range.

And what is it about the parts of the room that work vs those that don't?  Showing screens of the NavMesh, and where you're trying to go, would help a lot.

The problematic line in NavigationEngine_PolygonCollider reads:

Vector3 vertex = new Vector3 (pointsList[i].x, pointsList[i].y, _originPos.z);

Try inserting above it:

if (pointsList.Length >= i) continue;

What happens then?

dude

 I sometimes get this error when the character has to go around that corner

the blue X marks the walk to marker

the hotspot is slighty out of the nash mesh at the corner

and I can't reproduce the error all the time. It just happens sometimes.

I played around a little with the nav mesh and repositioned the walk to marker a bit.

For now the error doesn't occur anymore.

 But maybe it is something worth looking into because it might happen at some other corner in ac-games. or just add a couple of try catch into the code so in case something happens it does nothing and the user has to tap again 

 when I add if (pointsList.Length >= i) continue; above

then I get this when the player tries to go around the corner

is it ok to have  markers outside of the nav mesh?

never had a problem with it before. I need it because I teleport a lot outside of the visible area.

You should always try to place your any Marker the player can navigate to within the NavMesh boundary.  If one is outside, AC will instead attempt to make the player move to the edge of the NavMesh that's nearest to it - but will still keep the player within.
