heres an interesting error i don't understand even 1%. I decided to make my ship game pseudo 3d and reminiscent of Gradius. All well and good. Except im using 2 limbs. One to mark the position of the booster particle effect. (which will have another limb to help orient the direction to fire it). and another limb to orient the front for shooting. Now the problem is im getting strange conflicts with my ship object and its limbs. heres my source:

Main:

#include "DarkGDK.h"
#include "player.h"

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 60 );
	dbAutoCamOff();
	//initial player setup
	dbLoadObject("models/Rune_1.3ds",1);
	dbPositionCamera(-300,0,-200);
	dbPointCamera(dbObjectPositionX(1),dbObjectPositionY(1),dbObjectPositionZ(1));
	int pitch=dbObjectAngleX(1);
	int origin=dbObjectAngleX(1);
	int player_x=dbObjectPositionX(1);
	int player_y=dbObjectPositionY(1);
	int player_z=dbObjectPositionZ(1);
	//create particles for booster
	dbMakeObjectSphere(2,10);
	dbMakeMeshFromObject(2,2);
	dbDeleteObject(2);
	dbAddLimb(1,1,2);
	dbAddLimb(1,2,2);
	dbDeleteMesh(2);
	dbOffsetLimb(1,1,0,0,20);
	dbOffsetLimb(1,2,0,0,-20);
	dbColorObject(1,RGB(255,0,0));
	dbColorLimb(1,3,RGB(0,255,0));
	dbColorLimb(1,2,RGB(0,0,255));
	// our main loop
	while ( LoopGDK ( ) )
	{
		pitching(pitch,origin);//handles ship pitching
		v_move(player_x,player_y,player_z);//moves the ship up and down
		refresh(pitch,player_x,player_y,player_x);//draws the ship
		// update the screen
		dbSync ( );
	}

// return back to windows
	return;
}

+ Code Snippet

#include "DarkGDK.h"
#include "player.h"

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 60 );
	dbAutoCamOff();
	//initial player setup
	dbLoadObject("models/Rune_1.3ds",1);
	dbPositionCamera(-300,0,-200);
	dbPointCamera(dbObjectPositionX(1),dbObjectPositionY(1),dbObjectPositionZ(1));
	int pitch=dbObjectAngleX(1);
	int origin=dbObjectAngleX(1);
	int player_x=dbObjectPositionX(1);
	int player_y=dbObjectPositionY(1);
	int player_z=dbObjectPositionZ(1);
	//create particles for booster
	dbMakeObjectSphere(2,10);
	dbMakeMeshFromObject(2,2);
	dbDeleteObject(2);
	dbAddLimb(1,1,2);
	dbAddLimb(1,2,2);
	dbDeleteMesh(2);
	dbOffsetLimb(1,1,0,0,20);
	dbOffsetLimb(1,2,0,0,-20);
	dbColorObject(1,RGB(255,0,0));
	dbColorLimb(1,3,RGB(0,255,0));
	dbColorLimb(1,2,RGB(0,0,255));
	// our main loop
	while ( LoopGDK ( ) )
	{
		pitching(pitch,origin);//handles ship pitching
		v_move(player_x,player_y,player_z);//moves the ship up and down
		refresh(pitch,player_x,player_y,player_x);//draws the ship
		// update the screen
		dbSync ( );
	}

	// return back to windows
	return;
}

player.h:

+ Code Snippet

#include "pitching.h"
#include "refresh.h"
#include "v_move.h"

pitching.h:

+ Code Snippet

#define PITCHING

void pitching(int& pitch, int origin)
{
	if( dbUpKey() && pitch < (origin+30) )//check and handle the pitching of the ship
		{
			pitch++;
		}
		else
		{
			if( dbDownKey() && pitch > (origin-30) )
			{
				pitch--;
			}
			else
			{
				if(pitch>origin)
				{
					pitch--;
				}
				else
				{
					if(pitch<origin)
					{
						pitch++;
					}
				}
			}
		}
};

v_move.h:

+ Code Snippet

#define V_MOVE

void v_move(int& player_x,int& player_y, int& player_z)
{
	if(dbUpKey()&& player_y<200 )
		{
			player_y++;
		}
		else
		{
			if(dbDownKey()&& player_y>-200 )
			{
				player_y--;
			}
		}
}

refresh.h:

+ Code Snippet

#define REFRESH

void refresh(int& pitch, int& player_x, int& player_y, int& player_z)
{	
		dbRotateObject(1,pitch,0,0);
		dbPositionObject(1,player_x,player_y,player_x);
}

now it worked flawlessly...until i added those limbs. When I added the limbs, all of a sudden limb#1 was being treated as the root object. But limb number one was referring to both the root object(the ship) and the limb. Limb number 2 referred to the second limb. and number 3 refrerred to just the ship. I didnt even make a number 3!! i colored the limbs to check which was which and sure eneough the id's are all messed up. any ideas??

Hi Vesper103,

Here is some documented sample code:

#include "DarkGDK.h"

void DarkGDK ( void )
{
	dbSyncOn   ( );
	dbSyncRate ( 60 );
	dbAutoCamOff();

//make parent 
	dbMakeObjectSphere(1,20);//used ID numbers (1)

//make a generic limb and limb mesh
	dbMakeObjectSphere(2,10);//used ID numbers (1,2)
	dbMakeMeshFromObject(3,2);//used ID numbers (1,2,3)

//setup camera
	dbPositionCamera(-300,0,-200);
	dbPointCamera(dbObjectPositionX(1),dbObjectPositionY(1),dbObjectPositionZ(1));
	int pitch=dbObjectAngleX(1);
	int origin=dbObjectAngleX(1);
	int player_x=dbObjectPositionX(1);
	int player_y=dbObjectPositionY(1);
	int player_z=dbObjectPositionZ(1);
	//create particles for booster
	
	
	//attach  limbs to parent
	dbAddLimb(1,1,3);
	dbAddLimb(1,2,3);

//delete generic limb and limb mesh
	dbDeleteObject(2);//ID2 is freed up //used ID numbers (1,3)
	dbDeleteMesh(3);//ID3 is freed up //used ID numbers (1)

//position the limbs
	dbOffsetLimb(1,1,0,0,20);
	dbOffsetLimb(1,2,0,0,-20);

//color the model
	dbColorObject(1,RGB(255,0,0));
	dbColorLimb(1,1,RGB(0,255,0));
	dbColorLimb(1,2,RGB(0,0,255));

// our main loop
	while ( LoopGDK ( ) )
	{

dbSync ( );
	}

// return back to windows
	return;
}

#include "DarkGDK.h"


void DarkGDK ( void )

	dbSyncOn   ( );

Your problem is that you are not keeping track of already used ID numbers.

My first attempt at this also.....had me puzzled for a while

EDIT: and again I also forgot to include before exiting

//free up resources
dbDeleteObject(1)//ID1 is freed up//used ID numbers (NONE)

As you can see, I am a noob also.
