Scene Loading Example

[macklebee]

The noise.dds is in the SDK now... not sure when it got added back in though but its in the materials/effects folder.

[Marleys Ghost]

Note the change: shaders.pak not textures.pak ... see told you I was full of beer

 

Again all complaints addressed in PM and sent to Macklebee .....

 

 

[AndiSenior]

still the same problem...

 

the noise.dds is in materials/effect folder

shaders.pak in the directory where the source code is

all engine related dll's are also in source directory

RegisterAbstractPath() points to the correct folder

 

no idea what the problem is....

 

copied the noise.dds to the source directory and it works!

but this cant be the way...

[macklebee]

does the noise.dds load now? the uniform variable warnings are normal and shouldn't cause a crash... if its still crashing it points to some other issue...

[Marleys Ghost]

still the same problem...

 

the noise.dds is in materials/effect folder

 

 

which is where? (the materials/effect folder that is)

[AndiSenior]

yes it loads the texture if I copy it to the source directory.

warnings: aosizereduce and ssaostrength does not exits.

but it works now.

no idea why I have to copy this texture....

can you post your abstractpath line?

[AndiSenior]

RegisterAbstractPath("D:\Program Files\Leadwerks Engine SDK");

[Marleys Ghost]

And "Leadwerks Engine SDK" is the install directory for 2.3 yes?

[AndiSenior]

sorry it's all working now without copying the texture.

slashes instead of backslashes in the abstract path registration did it

thanks anyway for your immediate support

hope you will forgive newbies

 

thanks

No problems at all Andi, am glad its all working now

[PcWizKid]

HMMM

[panoramix]

RegisterAbstractPath("D:\Program Files\Leadwerks Engine SDK");

 

glad to see you fixed it, in C it should be double backslashes (because backslash is a escape character)

RegisterAbstractPath("D:\\Program Files\\Leadwerks Engine SDK");

 

your solution works as well, but I'm not sure why...

RegisterAbstractPath("D:/Program Files/Leadwerks Engine SDK");

[ArBuZ]

Using VC++ 2008 Express

 

Use the 2.3 Project Wizard to create a new project

 

I simply called the example "sceneloading" (again ...)

 

Delete the generated example code in sceneloading.cpp

 

Replace with the following code:

 

 

#include "engine.h"

int main(int argc, char** argv)
{
Initialize();
RegisterAbstractPath("PATH TO YOUR SDK FOLDER");
Graphics(800,600);

AFilter() ;
TFilter() ;

TWorld world = CreateWorld() ;
if (!world) {
MessageBoxA(0,"Error","Failed to create world.",0);
return Terminate();
}

TFramework framework=CreateFramework();
TLayer layer = GetFrameworkLayer(0);
TCamera cam=GetLayerCamera(layer);
PositionEntity(cam,Vec3(0,0,0));

//Set Lua variable
BP L=GetLuaState();
lua_pushobject(L,framework);
lua_setglobal(L,"fw");
lua_pop(L,1);

// Setup Initial Post Processing FX
SetGodRays(1);
SetHDR(1);
SetSSAO(1);
SetBloom(1);
SetAntialias(1);
SetStats(2);

LoadScene("abstract::YOUR_SCENE.sbx");

// Setup spectator
TBody spectator=CreateBodySphere();
SetBodyMass(spectator,1);
SetBodyGravityMode(spectator,0);
SetBodyDamping(spectator,1.0);
EntityType(spectator,3);
SetBodyBuoyancyMode(spectator,0);
PositionEntity(spectator,Vec3(0,5,-10));

TVec3 camrotation=Vec3(0);
float mx=0;
float my=0;
float move=0;
float strafe=0;

HideMouse();
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);

// MAIN LOOP
while (!KeyHit(KEY_ESCAPE))
{

mx=Curve(MouseX()-GraphicsWidth()/2,mx,6);
my=Curve(MouseY()-GraphicsHeight()/2,my,6);
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);

camrotation.X=camrotation.X+my/10.0;
camrotation.Y=camrotation.Y-mx/10.0;
RotateEntity(cam,camrotation);

move=KeyDown(KEY_W)-KeyDown(KEY_S);
strafe=KeyDown(KEY_D)-KeyDown(KEY_A);
TVec3 force = Vec3(strafe*10.0,0,move*10.0);
force=TFormVector(force,cam,0);
AddBodyForce(spectator,force);

UpdateAppTime();
UpdateWorld(AppSpeed()) ; 

PositionEntity(cam,EntityPosition(spectator));

// Update timing and world
UpdateFramework();

// Render
RenderFramework();

// Send to screen
Flip(0) ;
}

return Terminate();
}

 

Copy to the sceneloading project folder

 

engine.dll

newton.dll

shaders.pak

Scripts folder

 

from your 2.3 SDK folder

 

 

Create a scene and save it in the maps folder in your SDK folder. Should work, but I am having a few beers so address all complaints to .. erm ... Macklebee

 

If I use LEO Framework, how can I pass framework to LUA?

This doesnt work:

Framework *fw1=new Framework();
fw1->Create();

BP L=GetLuaState();
lua_pushobject(L,(BP)fw1);
lua_setglobal(L,"fw");
lua_pop(L,1);

LoadScene("C:/test/deserthighway.sbx");

 

It gives me error "Access violation reading location 0x2f005800" on LoadScene function. Im doing something wrong?

you cannot do this. you must choose between full C++ framewerk or engine.dll included framework.

Lua expects a handle to the engine.dll framework, the C++ framewerk is not compatible.

 

i know this because i also hit this problem, one solution would be to extract framework from engine.dll and create a framework.dll with defined header ... this way we could create a compatible framework.dll in C++ and lua could call exported methods without knowing it's bmx or C++ compiled code. But i don't think Josh is headed this way now that framework is included in engine.dll.

 

Anyway, if you don't want to modifiy the framework code, solution 2 with the engine.dll integrated framewrok is the easyest solution.

It should work, since it works in gamelib too (and gamelib is using LEO Framework):

 

from gamelib.cpp:

	luat.Create();					// create the LuaTools object
luat.SetScriptObject("fw",scene.framewerk);	// set the Lua variable fw

// Structs

int LuaTools::GetStackSize()
{
return GetTop();
}

void LuaTools::SetStackSize( int size )
{
int currentsize = GetStackSize();
if( size<currentsize )
	Pop( currentsize-size );
}

void LuaTools::SetScriptObject( const std::string& name, BP o )
{
int size = GetStackSize();
PushObject( o );
SetGlobal( name );
SetStackSize( size );
}

 

from gamelib.h:

// Structs

class LuaTools : public Lua
{
public:
int GetStackSize();
void SetStackSize( int size );
void SetScriptObject( const std::string& name, BP o );
};

very interresting ... i'll have a closer look at LEO. Thanks

 

EDIT : Hmmm ... when i see this in LEO framework

 

   inline void Framework::Update() const
   {
	::leUpdateFramework();
   }

   inline void Framework::Render() const
   {
	::leRenderFramework();
   }

 

this makes me think LEO is calling the engine.dll framework methods ... and not the C++ framewerk renderer methods

 

not sure but probable

 

in that case it will work, but the C++ framewerk is not used

[Canardia]

Yes, LEO is using Framework, not Framewerk.

And ArBuZ is using LEO Framework also:

Framework *fw1=new Framework();

However, he seems to be passing **fw to Lua, and not *fw, that might be the problem.

Happy you found out Arbuz problem. If it's just a C++ coding issue than you're far better than me for sure.

 

What will happen with the old C++ framewerk. Totally deprecated or a come back is possible ?

[Canardia]

You can still use it for games which don't use Lua, also in LE 2.3.

You could also use it for games which use Lua, but then you need to customize a few entity scripts.

[Elmar]

How i can load this sky material, without the creating framewerk?

[diedir]

sorry to knock at this door again but i got trouble with LE 2.31

not working on compile project

 

Exception non gérée à 0x1014eec4 dans projetx6.exe : 0xC0000005: Violation d'accès lors de la lecture de l'emplacement 0x00000068

 

and stopping in engine.cpp at these lines:

 

inline void RenderFramework(void)

thank you for helping

[Marleys Ghost]

Compiles ok for me. Using the deserthighway.sbx

 

How have you set the project up?

[diedir]

i set it like other wiki C++ tutorials, exactly like josh video tutos

(was working with "camera controls" official tuto)

i think i am wrong somewhere here

 

general dir out : "..\$(ConfigurationName)"

 

debug working dir : "../.."

 

C++ with include dir "SDK_path/CPP"

 

link editor: "../../$(ProjectName).exe"

 

that's all i can see for my settings

 

thanks for help

[Marleys Ghost]

The LE Wizards much easier. but have you copied over the DLL's, shader.pak and scripts directory to your app dir. ?
