Adds an [Array] the size of [constant Mesh.ARRAY_MAX] and with vertices at index [constant Mesh.ARRAY_VERTEX] and indices at index [constant Mesh.ARRAY_INDEX] to the navigation mesh baking data. The array must have valid triangulated mesh data to be considered. Since [NavigationMesh] resources have no transform, all vertex positions need to be offset by the node's transform using [param xform].

Adds a projected obstruction shape to the source geometry. The [param vertices] are considered projected on a xz-axes plane, placed at the global y-axis [param elevation] and extruded by [param height]. If [param carve] is [code]true[/code] the carved shape will not be affected by additional offsets (e.g. agent radius) of the navigation mesh baking process.

<description>
Returns the projected obstructions as an [Array] of dictionaries. Each [Dictionary] contains the following entries:
- [code]vertices[/code] - A [PackedFloat32Array] that defines the outline points of the projected shape.
- [code]elevation[/code] - A [float] that defines the projected shape placement on the y-axis.
- [code]height[/code] - A [float] that defines how much the projected shape is extruded along the y-axis.
- [code]carve[/code] - A [bool] that defines how the obstacle affects the navigation mesh baking. If [code]true[/code] the projected shape will not be affected by addition offsets, e.g. agent radius.
