| **Property** | **Description** |
|
||
|
|
| :------------------ | :------------------------ |
|
||
|
|
| **Drop Height** | Specify the maximum height from which this agent type can jump down. |
|
||

## Areas tab
|
||
|
|
The Areas tab contains properties that allow you to specify how difficult it is to walk across the different area types used in your scenes. There are 29 custom area types, and 3 built-in area types:
|
||
|
|
|
||
|
|
- **Walkable** is a generic area type which specifies that the area can be walked on.
|
||
|
|
- **Not Walkable** is a generic area type which prevents navigation. It is useful for cases where you want to mark a certain object to be an obstacle, but you don't want to put a NavMesh on top of it.
|
||
|
|
- **Jump** is an area type that is assigned to all auto-generated links that connect NavMeshes.
|
||
|
|
|
||
|
|
The following table describes the properties available on the Areas tab.

|
||
|
|
| **Name** | Specify a name for the area type. |
|
||
|
|
| **Cost** | Specify the cost of traveling across this area. Costs are multipliers applied to the distance traveled across an area. A cost of 2 means an area is twice as difficult to cross as an area with a cost of 1. The default value is 1. |
