# NavMeshLink
|
||
|
||
NavMesh Link creates a navigable link between two locations that use NavMeshes.
|
||
|
||
This link can be from point to point or it can span a gap, in which case the Agent uses the nearest location along the entry edge to cross the link.
|
||
|
||
You must use a NavMesh Link to connect different NavMesh Surfaces.
|
||
|
||
To use the NavMesh Link component, navigate to __GameObject__ > __AI__ > __NavMesh Link__.
|
||
|
||
|
||
|
||
## Parameters
|
||
| __Property__| __Function__ |
|
||
|:---|:---|
|
||
| __Agent Type__| The Agent type that can use the link.|
|
||
| __Start Point__| The start point of the link, relative to the GameObject. Defined by XYZ measurements. |
|
||
| __End Point__| The end point of the link, relative to the GameObject. Defined by XYZ measurements. |
|
||
| __Align Transform To Points__| Clicking this button moves the GameObject at the link’s center point and aligns the transform’s forward axis with the end point. |
|
||
| __Cost Modifier__| When the cost modifier value is non-negative the cost of moving over the NavMeshLink is equivalent to the cost modifier value times the Euclidean distance between NavMeshLink end points.
|
||
| __Bidirectional__| With this tickbox checked, NavMesh Agents traverse the NavMesh Link both ways (from the start point to the end point, and from the end point back to the start point).<br/>When this tickbox is unchecked, the NavMesh Link only functions one-way (from the start point to the end point only). |
|
||
| __Area Type__| The area type of the NavMesh Link (this affects pathfinding costs). <br/> - __Walkable__ (this is the default option)<br/> - __Not Walkable__ <br/> - __Jump__ |

## Connecting multiple NavMesh Surfaces together
|
||
|
||
|
||
|
||
If you want an Agent to move between multiple NavMesh Surfaces in a Scene, they must be connected using a NavMesh Link.
|
||
|
||
In the example Scene above, the blue and red NavMeshes are defined in different NavMesh Surfaces, with a NavMesh link connecting them.
|
||
|
||
Note that when connecting NavMesh Surfaces:
|
||
|
||
* You can connect NavMesh Surfaces using multiple NavMesh Links.
|
||
|
||
* Both the NavMesh Surfaces and the NavMesh Link must have same Agent type.
|
||
|
||
* The NavMesh Link’s start and end point must only be on one NavMesh Surface - be careful if you have multiple NavMeshes at the same location.
|
||
|
||
* If you are loading a second NavMesh Surface and you have unconnected NavMesh Links in the first Scene, check that they do not connect to any unwanted NavMesh Surfaces.
