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.

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

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

Arguments

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

Return value

true if:

• The current mesh name coincides the new name.
• The mesh with the new name has been loaded successfully.
• The force flag is set to 0.

In other cases, false.

const char * getMeshName ( ) #

Returns the name of the mesh used as a base for the navigation mesh.

Return value

The mesh name.

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.
