<brief_description>
|
|
A mesh that defines the areas traversable by navigation agents that are safe from obstructions.
|
|
</brief_description>
|
|
<description>
|
|
A NavigationMesh is used in pathfinding to describe the traversable area that is safe from collision and other obstructions, assuming an agent's center position at zero radius. The mesh data can be created and baked to polygons with the [NavigationMeshGenerator] by parsing source geometry from the [SceneTree]. The mesh data can also be created without baking by adding the required arrays of vertices and polygon indices with a script.
|
|
When making procedual changes, a call to [method commit_changes] is required to apply these changes and to synchronize them with the [NavigationServer].
