Vehicle implementation

[ZeroByte]

Yes, thank's for that sample Josh.

[Canardia]

The default suspensionlength in the headers will be half of the tire radius, as suggested by Josh.

[ZeroByte]

Ok, thank's Lumooja, good to know.

[ZeroByte]

Do you guy's know if this will work with LEO in c++.

 

I just started using LEO, and i'm not sure if LEO needs

 

to be updated also, or if it can be ported to LEO ?

 

It's working great with C though, just not sure how to set it up in LEO.

 

Thank's for any info.

[Josh]

Should work just the same. The wiki has the C++ and C commands.

[ZeroByte]

Ok, thank's Josh, i'll try setting it up in LEO then.

Hi, here is a LEO vehicle example, if anyone is interested:

 

#include "leo.h"

using namespace LEO ;

float steerangle=0.0;

int main( int argn, char* argv[] )
{
Engine engine( "leocar", 1280, 800 ) ;
Engine::SetAbstractPath( "C:/Leadwerks Engine SDK" ) ;
Engine::SetFilters() ;

World world( CREATENOW ) ;
if( !world.IsValid() ) 
{
	MessageBoxA(0,"Error","Failed to create world.",MB_OK);
	return engine.Free() ;
}

Buffer gbuffer( Engine::GetWidth(), Engine::GetHeight() );

Camera camera( CREATENOW );
camera.SetPosition( 0, 0, -10 );

Material material("abstract::cement_asphaltscales-01_df_.mat") ;

//DebugPhysics();

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

SetWorldGravity(Vec3(0, -20, 0));
LEO::Collisions::Set(1,1,SLIDINGCOLLISION);

// Vehicle
Model chassis;
chassis.Load("abstract::impreza.gmf", 0); 
chassis.SetType(1);
chassis.SetMass(10);

Mesh tire[4];
tire[0].Load("abstract::vehicle_monstertruck_tire_left.gmf", 0);
tire[1].Load("abstract::vehicle_monstertruck_tire_right.gmf", 0);
tire[2].Load("abstract::vehicle_monstertruck_tire_left.gmf", 0);
tire[3].Load("abstract::vehicle_monstertruck_tire_right.gmf", 0);

RotateMesh(tire[0],Vec3(0,0,90));
   RotateMesh(tire[1],Vec3(0,0,90));
   RotateMesh(tire[2],Vec3(0,0,90));
   RotateMesh(tire[3],Vec3(0,0,90));

Vehicle veh;
veh.Create(chassis);

veh.AddTire(Vec3(-1.4,0,1.4),0.5,1.0,80,200);
veh.AddTire(Vec3(1.4,0,1.4),0.5,1.0,80,200);
veh.AddTire(Vec3(-1.4,0,-1.4),0.5,1.0,80,200);
veh.AddTire(Vec3(1.4,0,-1.4),0.5,1.0,80,200);

BodyBox groundbody( 100, 1, 100 ) ;
Cube ground( CREATENOW ) ;
ground.SetScale( 100, 1, 100 );
groundbody.SetParent( ground ) ;
ground.SetPosition( 0, -3, 0 );
ground.Paint( material ) ;
groundbody.SetType(1);

// Game loop
while( !Keyboard::I****() && !Engine::IsTerminated() )
{
	if( !Engine::IsSuspended() ) 
	{

		// Steering
		if (KeyDown(KEY_LEFT) && (steerangle<=40.0f)) {
			steerangle+=1.0f;
			SetSteerAngle(veh, steerangle, 0);
			SetSteerAngle(veh, steerangle, 1); }

		if (KeyDown(KEY_RIGHT) && (steerangle>=-40.0f)) {
			steerangle-=1.0f;
			SetSteerAngle(veh, steerangle, 0);
			SetSteerAngle(veh, steerangle, 1); }

		// Torque
		AddTireTorque(veh, 0, -1);
		if (KeyDown(KEY_UP)) AddTireTorque(veh, 10, -1); 
		if (KeyDown(KEY_DOWN)) AddTireTorque(veh, -10, -1); 

		if (KeyDown(KEY_SPACE)) AddBodyForce(chassis, Vec3(0,200,0), 1); // Lift car

		SetEntityMatrix(tire[0],veh.GetTireMatrix(0));
           SetEntityMatrix(tire[1],veh.GetTireMatrix(1));
           SetEntityMatrix(tire[2],veh.GetTireMatrix(2));
           SetEntityMatrix(tire[3],veh.GetTireMatrix(3));

		Engine::UpdateTime();
		World::Update( Engine::GetSpeed()) ;

		gbuffer.Set();
		World::Render() ;
		Engine::GetBackBuffer().Set() ;
		World::RenderLights(gbuffer);

		Engine::Flip() ;
	}
}

return engine.Free() ;
}

 

I used the monstertruck tires from LE 2.3 SDK, because i can't get the

 

wheel textures to show up on the car wheels.

 

I removed the engine.dll, newton.dll, and shaders.pak from release dir.

 

And i removed the engine.cpp, and leo.cpp from the project.

 

Link to leocar.zip project: http://66.244.240.14/

 

Link isn't always up.

[ZeroByte]

I forgot the cement_asphaltscales-01_df_.mat file,

 

but you can just add your own texture.

[ZeroByte]

You will need the recompiled engine.dll Josh posted on this thread.

Hi all,

 

Good job Josh, and thanks to all to gave me some light to vehicle implentation.

I've to try yet, but i've a problem, VS 2008, doesn't recognise some identifiers like Framework, some phy functions, etc... My question is, I'm missing something?(any dll, or whatever) I can't understand it. I do what the Video tutorial "Setting Up VS 2008 c++ Express Edition" tells.

 

Pls help.

[Canardia]

In LE 2.0 you need to use Framewerk, not Framework.
