How transfer pathWorld server to client ?

Amnedge1331 · 05-09-2015 12:23 AM

hey so im coming to you, simply to ask, how would you pass a pathWorld from a client to a server to archieved a link between my ai client side and server side on their movement.

i'd like to handle the fact that when a item got set in the client/server side, the other one understand it without communication and have a sync every couple minutes to make sure they are similar (for exemple)

this would be to avoid killing the bandwidth on large regions, but maybe someone has a better idea ?

when i create my pathworld into my world, my region seems to not have any knowledge of it and the data disapear, someone knows why ?

ps: i am using inesis base with modified coding

Thanks

Someone got an idea ?

Usually this would be done by sending the object updating the pathworld to the clients instead of passing something as large as the entire pathworld, to my knowledge the navmesh should be accurate enough to be able to generate the exact same pathworld on both client and server. Is this not good enough? I can't see a reason why this would incurr a large bandwidth problem.

Now the pathworld is generated by client side, but there is a separation between each area of 1 meter like here:

Areas look good i don't know where is the problem, here a picture between 2 areas:

from what I remember you need to get the edge geometry from the neighboring areas as well for them to be connected.

Ok i see but actually i use de "parts" from the PhysBody of each area so how can I get the edge geometry from the neighboring areas ?

I need to add "parts" of other area neighbor into the calcul of one area ?

you can get the geometry from physbody by using the Mesh class or is it meshbase that allows creating a mesh from physbody.

I created this along time ago when creating my own worldmanager(not sure it compiles without altering some functions first).

Code:

static void SetDefaultPathType(MeshBase &mesh){

    if (!mesh.tri.flag()){ mesh.include(TRI_FLAG); REPA(mesh.tri)mesh.tri.flag(i) = PM_GROUND; }

    if (!mesh.quad.flag()){ mesh.include(QUAD_FLAG); REPA(mesh.quad)mesh.quad.flag(i) = PM_GROUND; }

}

static void CreatePath(Cell<Area> &cell,Ptr=nullptr){

        Area *a = nullptr;

    if(!(a = cell.data()))return;

    MeshBase mesh; mesh.add(MeshBase(a->phys));

    if(a->l() )mesh.add(MeshBase(a->l()->phys));

    if(a->r() )mesh.add(MeshBase(a->r()->phys));

    if(a->b() )mesh.add(MeshBase(a->b()->phys));

    if(a->f() )mesh.add(MeshBase(a->f()->phys));

    if(a->lb())mesh.add(MeshBase(a->lb()->phys));

    if(a->lf())mesh.add(MeshBase(a->lf()->phys));

    if(a->rb())mesh.add(MeshBase(a->rb()->phys));

    if(a->rf())mesh.add(MeshBase(a->rf()->phys));

    SetDefaultPathType(mesh);

    Rect drect(a->mat.pos.xz()-2,a->mat.pos.xz()+(World.HMRes()+1)); //create a scaled rectangle used for cutting edge geometry from neigbouring areas to prevent navmesh generation on excessive amount of data.

    if(!drect.validX())Swap(drect.min.x, drect.max.x);

    if(!drect.validY())Swap(drect.min.y, drect.max.y);

    Mems<Bool> vtx_is;vtx_is.setNumZero(mesh.vtxs());

    REPA(mesh.vtx){

        if(Cuts(mesh.vtx.pos(i).xz(), drect)){

            if(InRange(i, vtx_is))vtx_is[i]=true;

        }

    }

    Mesh d;d.add(mesh);

    mesh.create(d.splitVtx(0, vtx_is.data()));

    mesh.weldVtx();

    a->pm.create(mesh,a->_xz,World.ps);//path mesh

    a->Save();

    mesh.del();

    d.del();

}
