I have been digging through the PLSM Demo and there is a LOT there. Does anyone have a really basic example? I mean just like one terrain and movement?

try to modify Demo_Terrain from Ogre, making it using PLSM2 instead of TSM.
It should work out of the box.

right, just change the setWorldGeometry("terrain.cfg") to setWorldGeometry("paginglandscape2.cfg").

don't forget to include the library in the plugins.cfg and the correct datafiles in the correct path...

Sweet! I'll give this a shot! Thanks!

Ok, I gave this a shot, but it pops up and error that says

Error #: 7

Function: PagingLandScapeOptions::load

Description: You need to define a GroupName where to find the map definition file .

What does that mean?

means the the paginglandscape2.cfg in
setWorldGeometry("paginglandscape2.cfg").
may not be correct.

AH, ok, I still had it pointing to "terrain.cfg" Thanks!

Now I am trying to pull the simple terrain demo out of the c:\ogrenew\samples framework in to a project that I create and I am running into this error.

if I copy the executable into the ogrenew\samples\bin\debug directory it works fine, which leads me to believe that I am missing something.

did you copy paginglandscape2.cfg ?
does paginglandscape2.cfg has a DefaultMap config variable ?

CaseyB

yup and yup. Here is the source from the paginglandscape2.cfg



DefaultMap=Terrain_Scene_Manager_Terrain



puget_sound=ps_height_1k

#grand_canyon=gcanyon_height_4k2k

#terragen_generated=terragen16bits

#European_Alpes=Alpes

Terrain_Scene_Manager_Terrain=TsmTerrain

def=Default



# resource group name where to find map definition

GroupName=PLSM2



# Try forbidden textureformat combinations

TextureFormatDebug=no

I also modified the resources.cfg to include this



[PLSM2]

FileSystem=../Media/paginglandscape2



FileSystem=../Media/paginglandscape2/models

FileSystem=../Media/paginglandscape2/materials

FileSystem=../Media/paginglandscape2/materials/scripts

FileSystem=../Media/paginglandscape2/materials/textures

FileSystem=../Media/paginglandscape2/materials/programs



FileSystem=../Media/paginglandscape2/datasrcs

FileSystem=../Media/paginglandscape2/terrains

and added



Plugin=Plugin_PagingLandScapeSceneManager2

to the plugins.cfg

Strange.
plsm2 read file given on setWorldGeometry, opens it and search for DefaultMap in the file, and exception is raised if it doesn't exist.

So it along that line of action.

Does setWorldGeometry() has the good file as parameter ?

I was pointing it at the wrong file! Thank you very much and sorry for the trouble!!

Ok, so I have an app working using the Terrain demo, but now I am running into trouble when I try to pull out the ExampleApplication stuff. It dies on this line



void PagingLandScapeSceneManager::_updateSceneGraph(Camera * cam)

{

    // entry into here could come before setWorldGeometry 

    // got called which could be disastrous

    // so check for init

--->assert(mPageManager);

    if (isRenderQueueToBeProcessed(mPageManager->getPageRenderQueue()))

    {

it's line 283 in OgrePagingLandscapeSceneManager.cpp
Any ideas what I am setting up incorrectly?

you're starting to render frame before calling setWorldGeometry("...cfg") ?

You are a genius! Thank you, it was another STUPID mistake! :oops:
