Falling down inside a SBX scene

[ZioRed]

I am trying to load the tunnels.sbx scene within the sample maps in LE SDK 2.31 and add a TController to navigate throught it, but it happens that the Controller falls down as if the collision between the scene and the controller didn't work. The same happens trying to load every map, both the samples (deserthighway.sbx, terrain_arctic.sbx) and my custom.

 

As you can see I have set both Collisions and Body Mass on the Controller, the code is the folling:

Initialize();

RegisterAbstractPath("C:/Leadwerks Engine SDK");
SetAppTitle( "SceneTest" ) ;
Graphics( 800, 600 ) ;
AFilter();
TFilter();

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

TBuffer gbuffer = CreateBuffer(GraphicsWidth(),GraphicsHeight(),BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);

TCamera cam = CreateCamera();
CameraClearColor(cam,Vec4(0,0,1,1));

TModel scene = LoadScene("abstract::tunnels.sbx");
EntityType(scene, 2);
Collisions(1, 2, true);

TController player=CreateController();
EntityType(player, 1);
SetBodyMass(player, 1);
SetBodyDamping(player,0.0);
SetWorldGravity(Vec3(0,-20,0));
PositionEntity(player, Vec3(-3.41, 1.78, -4.86));

float move=0.0, strafe=0.0;
TVec3 camrotation=Vec3(0);
float mx=0, my=0;

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

// Game loop
while( !KeyHit() && !AppTerminate() )
{
if( !AppSuspended() ) // We are not in focus!
{
	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 = 3 * (KeyDown(KEY_W) - KeyDown(KEY_S));
	strafe = 3 * (KeyDown(KEY_D) - KeyDown(KEY_A));

	//Jumping
	float jump=0.0;
	if (KeyHit(KEY_SPACE)) {
		if (!ControllerAirborne(player)) {
			jump=4.0;
		}
	}
	//Run
	if (KeyDown(KEY_LSHIFT)||KeyDown(KEY_RSHIFT)) {
		if (!ControllerAirborne(player)) {
			move*=2.0;
			strafe*=2.0;
		}
	}

	UpdateController(player, camrotation.Y, move, strafe, jump, 500.0f);

	// Update timing and world
	UpdateAppTime();
	UpdateWorld(AppSpeed()) ;

	//Position the camera
	TVec3 playerpos=EntityPosition(player);
	TVec3 camerapos=EntityPosition(cam);
	camerapos.Y=Curve(playerpos.Y+1.75,camerapos.Y,2.0);
	camerapos=Vec3(playerpos.X,camerapos.Y,playerpos.Z);
	camerapos=Vec3(playerpos.X,camerapos.Y,playerpos.Z);
	PositionEntity(cam,camerapos);

	// Render
	SetBuffer(gbuffer);
	RenderWorld();
	SetBuffer(BackBuffer());
	RenderLights(gbuffer);

	// Send to screen
	Flip(0) ;
}
}

Am I forgetting something in the code?

Try positioning the camera in the editor to a place inside the map thats above a surface then open the .sbx file in notepad and use the camerapositon co-ordinates to set the position of the controller , see if that helps.

Or as a test if you have not moved anything in the standard Tunnels.sbx :

 

Try:

 

PositionEntity(player, Vec3(29.3175259,3.12580490,-18.8330040));

You might also think about using Framework saves a lot of hassle and setup.

But after trying out your code it seems it was simply the position of the controller when spawned, it was half way through the floor.

Here I converted your code over to use Framewerk just make sure you point the Abstract path to your SDK folder and have the DLL's , shader.pak and scripts folder in your app folder:

 

 

#include "engine.h"

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

AFilter(4) ;
TFilter(1) ;

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);

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

// Setup Initial Post Processing FX
SetGodRays(0);
SetHDR(1);
SetSSAO(1);
SetBloom(1);
SetAntialias(1);
SetStats(2);

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

TController player=CreateController();
EntityType(player, 1);
SetBodyMass(player, 1);
SetBodyDamping(player,0.0);
SetWorldGravity(Vec3(0,-20,0));
PositionEntity(player, Vec3(38.9101448,6.67733288,1.72972393));

float move=0.0, strafe=0.0;
TVec3 camrotation=Vec3(0);
float mx=0, my=0;

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

// Game loop
while( !KeyHit() && !AppTerminate() )
{
       if( !AppSuspended() ) // We are not in focus!
       {
               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 = 3 * (KeyDown(KEY_W) - KeyDown(KEY_S));
               strafe = 3 * (KeyDown(KEY_D) - KeyDown(KEY_A));

               //Jumping
               float jump=0.0;
               if (KeyHit(KEY_SPACE)) {
                       if (!ControllerAirborne(player)) {
                               jump=4.0;
                       }
               }
               //Run
               if (KeyDown(KEY_LSHIFT)||KeyDown(KEY_RSHIFT)) {
                       if (!ControllerAirborne(player)) {
                               move*=2.0;
                               strafe*=2.0;
                       }
               }

               UpdateController(player, camrotation.Y, move, strafe, jump, 500.0f);

               //Position the camera
               TVec3 playerpos=EntityPosition(player);
               TVec3 camerapos=EntityPosition(cam);
               camerapos.Y=Curve(playerpos.Y+1.75,camerapos.Y,2.0);
               camerapos=Vec3(playerpos.X,camerapos.Y,playerpos.Z);
               camerapos=Vec3(playerpos.X,camerapos.Y,playerpos.Z);
               PositionEntity(cam,camerapos);

			UpdateFramework();
			RenderFramework();

               // Send to screen
               Flip(0) ;
       }
}
}

Thank you for reply, I solved just while you were writing the last post only copying shaders.pak and Scripts folder in the compiled directory (I believed that since was declared RegisterAbstractPath thingoid than it was not necessary to copy those files). Now I'm receiving an error "Null framewerk" when hitting ESCAPE to shut down the program, I'll investigate about it (may use the Framework API instead of C [i love OOP and coming from C# ]), may be it's used inside some lua script of that scene/models.
