World Loading when Player is far

Barthap · 01-03-2011 08:13 PM

I have strange problem with loading world when player is far from heightmap center. If I set player near world 0,0 position and build it, it runs normally in World Editor Play and in my game. But if I put player to city, which is far from heightmap 0 position (its center), it runs normally in World Editor Play, but in game Players.elms() = 0. I don't know why. Here's my code:

Quote: Game::World.init();

Game::World.setObjType(Statics, OBJ_STATIC)
.setObjType(Trees, OBJ_TREE)
.setObjType(Players, OBJ_PLAYER)
.setObjType(Items, OBJ_ITEM)
.setObjType(Chrs, OBJ_CHR)
.setObjType(Fireballs, OBJ_FIREBALL)
.setObjType(Teleports1, OBJ_TELEPORT1)
.setObjType(Horses, OBJ_HORSE)
.setObjType(Destructs, OBJ_DESTRUCTIBLE)
.setObjType(Triggers, OBJ_TRIGGER)
.setObjType(Lights, OBJ_LIGHT_POINT);

//Game::World.New("World/hapgame.world");
SG.New("World/hapgame.world"); //Similiar code to Multiple Worlds tutorial (SaveGame.New())

Loader.start(); //World loader (from tutorial)

if(!Players.elms())Exit("Players.elms is 0 (after Loader.start()"); //debug code

I think that it's because world is loaded with streaming so if player is far away from update position it isn't loaded with world.

Ok, so what should I do? I can't turn off streaming and turn it on after loading, because my world is very very big.

well the only thing you have is that the player in only in memory... i don't think you can do much about the loading/unloading of areas.. or you want to render the entire world but i think that you dont want that.

So what you can do is to create the player in c++ so you know the player is active at the time the game starts. Or if you use 1 player only just make 1 object player and use that.

Maybe look to Esenthel RPG code where you load game. There should be a code to move camera to Player.

Dynad · 01-03-2011 09:42 PM

The player gets created at a starting waypoint like i said.... so thats maybe the only option you have atm

Yes, you need to reposition your camera (and thus center of action) to player position

you can use waypoint to access the initial position, further positions should be manually remembered

ok, i'll try do something with it

I changed code, loading world and player is the same as in Esenthel RPG2, but the effect is the same: Players.elms is 0.

My code

Code:

Game::World.init();

   Game::World.setObjType(Statics,    OBJ_STATIC)

            .setObjType(Trees,      OBJ_TREE)

            .setObjType(Players,    OBJ_PLAYER)

            .setObjType(Items,      OBJ_ITEM)

            .setObjType(Chrs,       OBJ_CHR)

            .setObjType(Fireballs,  OBJ_FIREBALL)

            .setObjType(Teleports1, OBJ_TELEPORT1)

            .setObjType(Horses,     OBJ_HORSE)

            .setObjType(Destructs,  OBJ_DESTRUCTIBLE)

            .setObjType(Triggers,   OBJ_TRIGGER)

            .setObjType(Lights,        OBJ_LIGHT_POINT);

   //Game::World.New("World/hapgame.world");

   SG.New("World/hapgame.world"); //SaveGame, same as in multiple worlds tutorial

 Game::ObjParamsPtr playerCharacter; playerCharacter.require("Obj/Chr/Warrior/0.obj");

 if(Game::Waypoint *waypoint=Game::World.getWaypoint("playerStart"))

 {

     if(waypoint->points())

     {

         Game::ObjParams obj;

         obj.base(playerCharacter);

         obj.type(true,"OBJ_PLAYER");

         Game::World.objCreate(obj,Matrix().setScalePos(obj.scale(),waypoint->point(0).pos));

                 LogN("OK.");

     }

     else LogN("Waypoint \"playerStart\" has 0 points");

 }

 else LogN("Waypoint \"playerStart\" not found");

//...

Bool UpdateGame()

{

   if(Loader.update()) return true; //BackgroundLoader update

//...

    if(!Game::World.updated())

    {

        Loader.start();

    }

    else

    {

        Game::World.update(Cam.at);

                //here players.elms is 0 too

    }

   return true;

}

My log.txt file shows only "OK."

Uptade your world not with Cam.at but at point 0 position of wypoint and then in update you can use update with Cam.at. Or move camera to point 0 before first update.

When you told me it, I did the same! smile

It works now!

It's working code:

Code:

//in Init()

Game::World.init();

   Game::World.setObjType(Statics,    OBJ_STATIC)

            .setObjType(Trees,      OBJ_TREE)

            .setObjType(Players,    OBJ_PLAYER)

            .setObjType(Items,      OBJ_ITEM)

            .setObjType(Chrs,       OBJ_CHR)

            .setObjType(Fireballs,  OBJ_FIREBALL)

            .setObjType(Teleports1, OBJ_TELEPORT1)

            .setObjType(Horses,     OBJ_HORSE)

            .setObjType(Destructs,  OBJ_DESTRUCTIBLE)

            .setObjType(Triggers,   OBJ_TRIGGER)

            .setObjType(Lights,        OBJ_LIGHT_POINT);

   Game::World.New("World/yourworld.world"); //normal version

   //SG.New("World/yourworld.world"); //multiple world tutorial version

 //Player params

 Game::ObjParamsPtr playerCharacter; playerCharacter.require("Obj/Chr/Warrior/0.obj");

 //checking for waypoint "playerStart"

 if(Game::Waypoint *waypoint=Game::World.getWaypoint("playerStart"))

 {

     if(waypoint->points())

     {

                 //creating player on waypoint position

         Game::ObjParams obj;

         obj.base(playerCharacter);

         obj.type(true,"OBJ_PLAYER");

         Game::World.objCreate(obj,Matrix().setScalePos(obj.scale(),waypoint->point(0).pos));

         Cam.setPosDir(waypoint->pos(0));  //set camera to player position

     }

 }

//in Update()

//at begin of Update() function

if(Loader.update()) return true;  //background loader start (from tutorial)

//at the end of Update() function (or somewhere in middle)

    if(!Game::World.updated()) // if current world hasn't yet been updated, it means it's a new or load game, so let background loader handle it

    {

        Loader.start();

    }

    else

    {

        Game::World.update(Cam.at);

        //set camera

        //update other things (clouds, water, mouse udpate

        //some other

    }

Using this code you have to add single waypoint in World Editor and name it "playerStart" there, where should be player start position. DON'T CREATE PLAYER OBJECT IN WORLD EDITOR. Just add only that waypoint there smile
