Unigine::NavigationMesh Class

Header: #include <UniginePathFinding.h>
Inherits from: Navigation

This class enables to create a navigation area above the surface of an arbitrary mesh. In fact, the navigation mesh is the area of the specified height above the mesh polygons, which is available for pathfinding.

Notice
A mesh used as a base for the navigation mesh should meet the requirements described here.

  • A set of samples located in the data/samples/paths folder:
    1. mesh_00

NavigationMesh Class

Members


static NavigationMeshPtr create ( ) #

Constructor. Creates an empty navigation mesh.

static NavigationMeshPtr create ( const char * arg1 ) #

Creates a navigation mesh from the given *.mesh file.

Arguments

  • const char * arg1 - Path to the *.mesh file.

void setDepth ( int depth ) #

Sets a depth value. The larger the depth value, the better control over accuracy and speed of route calculation is provided.

Arguments

  • int depth - A depth, which is an integer value in range [0;4].

int getDepth ( ) #

Returns the depth value, which is an integer value in range [0;4]. The larger the depth value, the better control over accuracy and speed of route calculation is provided.

Return value

The depth value.

void setHeight ( float height ) #

Sets the distance above the navigation mesh polygons that is available for pathfinding. By default, the height is set to 1.

Arguments

  • float height - Height in units.

float getHeight ( ) #

Returns the distance above the navigation mesh polygons that is available for pathfinding. By default, the height is set to 1.

Return value

Height in units.

int setMesh ( const Ptr<Mesh> & mesh ) #

Copies a given mesh into the mesh, on which the current navigation mesh is based.

Arguments

  • const Ptr<Mesh> & mesh - Mesh to be copied.

Return value

1 if the mesh is copied successfully; otherwise, 0.

int getMesh ( const Ptr<Mesh> & mesh ) #

Copies the mesh that is used as a base for the current navigation mesh into the received mesh.
Notice
A mesh used as a base for the navigation mesh should meet the requirements described here.

Arguments

  • const Ptr<Mesh> & mesh - A mesh into which the current mesh is copied.

Return value

1 if the mesh is copied successfully; otherwise, 0.

int setMeshPath ( const char * path, int force_load = 0 ) #

Sets a new path for the mesh used as a base for the navigation mesh and forces loading of the mesh with the new path for the current navigation mesh.

Arguments

  • const char * path - Path to the *.mesh-file to be set.
  • int force_load - Force flag.
    • If 1 is specified, the mesh with the new path will be loaded immediately.
    • If 0 is specified, only the mesh path will be updated.

Return value

true if:
  • The current mesh path coincides the new path.
  • The mesh with the new path has been loaded successfully.
  • The force flag is set to 0.
In other cases, false.

const char * getMeshPath ( ) #

Returns the path to the .mesh-file containing a base mesh for the navigation mesh.

Return value

Path to the *.mesh-file.

int loadMesh ( const char * path ) #

Loads a mesh, on which the navigation mesh is based, from the file. This function doesn't change the mesh name.

Arguments

  • const char * path - A relative path to the *.mesh-file.

Return value

1 if the mesh is loaded successfully; otherwise, 0.

int saveMesh ( const char * path ) #

Saves the mesh, on which the navigation mesh is based, to the file.

Arguments

  • const char * path - A relative path to the *.mesh file.

Return value

1 if the mesh is saved successfully; otherwise, 0.

static int type ( ) #

Returns the type of the node.

Return value

Navigation type identifier.
