CreateNavMesh

This function creates a new navigation mesh for pathfinding.

Syntax

shared_ptr<NavMesh> CreateNavMesh(shared_ptr<World> world, const float height, const int tilesx, const int tilesz, const int tileres = 32, const float voxelsize = 0.25, const float agentradius = 0.4, const float agentheight = 1.8, const float stepheight = 0.501, const float maxslope = 45.01)

Parameter	Description
world	world to create the navmesh in
height	width of the navmesh volume
tilesx	number of tiles along the X axis
tilesz	number of tiles along the Z axis
tileres	number of voxels per tile
voxelsize	resolution of voxel grid
agentradius	radius of the characters that will use this navmesh
agentheight	height of the characters that will use this navmesh
stepheight	maximum height that can be stepped up
maxslope	maximum slope that can be traversed, in degrees

Returns

Returns a new Navmesh object.
