Overview
Obstacle shape (navigational obstacle) – this is used when you do not need an NPC to enter a certain area on a map, or completely block their path.

|
| Rotation: Rotating the selected obstacle shape according to given numerical values along the 3 grid axes X, Y, Z. |
| Scale: | Scaling the selected obstacle shape according to given numerical values along the 3 grid axes X, Y, Z. |
|
| Uniform: Multiplier that is applicable to all three axes at once; allows to edit the scale simultaneously on three axes. |
|
| Random Rotation: Random rotation of the selected obstacle shape in line with given numerical values along the 3 grid axes X, Y, Z. |

| Static Data Key: Name of the object type. One class might have several different types. For example, you can create several weapons of the same type. They will have the same set of static properties but their values will be different. |
|
| Group: Editor group name (optional). |
|
| Bounding Size: AABB (axis-aligned bounding box) size. |
|
| Tag: A tag assigned by the user. |
|
| Lock Transform: This locks the object's movement, scaling, and rotation in the scene. Those can still be changed in the Properties window. When the map reloads, this will automatically unlock. |
|
| Lock to Heightmap: Obstacle shape locked to the heightmap. |
|
| Layer: Layer where the object lies. |
Shape | Type | Box |
|
| Position: Moving the selected obstacle shape according to given numerical values along the 3 grid axes X, Y, Z. |
|
| Rotation: Rotating the selected obstacle shape according to given numerical values along the 3 grid axes X, Y, Z. |
|
| Half Size: Scaling the selected obstacle shape according to given numerical values along the 3 grid axes X, Y, Z. |
Persistent: |
| If a check mark is set on Persistent, then the NPC will be blocked by the selected obstacle_shape. |
If you change the size of the obstacle shape, and it changes its color to red, this means the shape is not suitable and it is impossible to place the obstacle.
Examples of using
Cannot move from zone 1 to zone 2, or from zone 2 to zone 1 (if Persistent is activated or obstacle_shape is activated on Visual script by the Action node).
NPCs will bypass the area where there is no obstacle.
