Problem with Framework and LEO

[ArBuZ]

Hi! Ive tried to use framework directly that included in dll. Here is the simple code. When I try to move any camera of any layer the program gives an error.

#include "leo.h"
using namespace LEO ;

int WINAPI WinMain( HINSTANCE hInstance,
				HINSTANCE hPrevInstance,
				LPSTR lpCmdLine,
				int nShowCmd ) 
{
Engine engine( "Gma", 1024, 768) ;
Engine::SetAbstractPath( "C:/Gma/Gma" ) ;
Engine::SetFilters() ;


Framework fw;
fw.Create();

fw.renderer.SetBloom(false);
fw.renderer.SetHDR(false);

//THIS CAUSE ERROR!
fw.main.GetCamera().SetPosition(Vec3(0,0,-5));


Material material("abstract::cobblestones.mat") ;
Cube	 mesh( CREATENOW ) ;
mesh.Paint( material ) ;

Cube ground( CREATENOW ) ;
ground.SetScale( 10, 1, 10 );
ground.SetPosition( 0, -2, 0 );
ground.Paint( material ) ;

DirectionalLight light( CREATENOW ) ;
light.SetRotation( 45 , 45, 45 );

// Game loop
while( !Keyboard::I****() && !Engine::IsTerminated() )
{
	if( !Engine::IsSuspended() ) // We are not in focus!
	{
		// Rotate cube
		mesh.Turn( Vec3( 0.5f*AppSpeed() ) ) ;


		fw.Update();
		fw.Render();

		Engine::Flip(0) ;
	}
}

// Done
return engine.Free() ;
}

 

But if I use API (not LEO) everything goes well:

{

Engine::SetFilters() ;


Framework fw;
fw.Create();

fw.renderer.SetBloom(false);
fw.renderer.SetHDR(false);

//THIS CAUSES ERROR!
//fw.main.GetCamera().SetPosition(Vec3(0,0,-5));

       //THIS WORKS!!!!
PositionEntity(GetLayerCamera(fw.main),Vec3(0, 0, -3.5));


Material material("abstract::cobblestones.mat") ;
Cube	 mesh( CREATENOW ) ;
mesh.Paint( material ) ;

Cube ground( CREATENOW ) ;
ground.SetScale( 10, 1, 10 );
ground.SetPosition( 0, -2, 0 );
ground.Paint( material ) ;

DirectionalLight light( CREATENOW ) ;
light.SetRotation( 45 , 45, 45 );

// Game loop
while( !Keyboard::I****() && !Engine::IsTerminated() )
{
	if( !Engine::IsSuspended() ) // We are not in focus!
	{
		// Rotate cube
		mesh.Turn( Vec3( 0.5f*AppSpeed() ) ) ;


		fw.Update();
		fw.Render();

		Engine::Flip(0) ;
	}
}

// Done
return engine.Free() ;
}

 

This works too

Camera cam=GetLayerCamera(fw.main);
cam.SetPosition( 0, 0, -3.5 );

 

But this doesnt:

Camera cam=fw.main.GetCamera();
cam.SetPosition(0,0,-5);

 

 

Maybe Im doing somethig wrong. Sorry if this problem is allready discribed on the forum.

It works only in Release mode, in Debug mode I get also the error, and the camera entity is sometimes NULL and sometimes some lower value than the real camera value.

Seems rather like a bug in Visual Studio C++ to me, since how can something work in Release but not in Debug?

I'll try to find a hack which makes it work in Debug mode also.

Has LEO been updated to include functions for Framework?

Yes. You can see all details of LEO changes in CPP/LEO/changes.txt.

OK, I found a hack for leoLayer.h which makes it work in Debug mode also. Just need Josh to update it. The good thing is, it makes GetWorld() and GetCamera() functions a bit faster too, since they use now a pointer instead of calling framework functions each time.

 

It allows also more LUA/BlitzMax style coding now, since you can say now:

fw.main.camera.SetPosition(0,0,-5);

and of course the strict OOP syntax works also:

fw.GetMain().GetCamera().SetPosition(Vec3(0,0,-5));

Awesome Lumooja, thanks

More than likely Debug mode is catching problem that is going unnoticed in Release mode.

Thank you Lumooja.

Ive noticed also that sometimes entity of any class in LEO becomes NULL or badptr in some cases. I cant remeber now how did that happen. But I had to use API instead of LEO.

 

And by the way

fw.GetMain()

is absent in dll framework.

 

And everything works if I use framewerk.cpp (not DLL). I think that something wrong with LEO.
