IO Class(es)

[GoogleCodeExporter]

It would be nice to have a class or 2 that serializes/deserializes the 
navmesh. 

My project has some large/complex navmeshes that need to be pre-generated & 
saved.

Serializing the mesh as simple as follows, there is no need to create classes 
for
that. I could have it included in some example, though. (untested code, could 
use few
sanity checks). 

// Write
unsigned char* navData = 0;
int navDataSize = 0;
dtCreateNavMeshData(m_pmesh->verts, m_pmesh->nverts, m_pmesh->polys,
        m_pmesh->npolys, m_pmesh->nvp,
        m_cfg.bmin, m_cfg.bmax, m_cfg.cs, m_cfg.ch,
        m_dmesh->meshes, m_dmesh->verts, m_dmesh->nverts,
        m_dmesh->tris, m_dmesh->ntris, 
        &navData, &navDataSize);
FILE* fp = fopen("navmesh.nm", "rb");
fwrite(navData, navDataSize, 1, fp);
fclose(fp);

// Read
FILE* fp = fopen(fileName, "rb");
fseek(fp, 0, SEEK_END);
int navDataSize = ftell(fp);
fseek(fp, 0, SEEK_SET);
unsigned char* navData = new unsigned char[navDataSize];
fread(navData, navDataSize, 1, fp);
fclose(fp);

m_navMesh = new dtStatNavMesh;
m_navMesh->init(navData, navDataSize, true);
