Here's a code of my loading screen..Its on the initialize function.
My loading screen doesn't work and i dont know why..

How do I make or implement a loading screen correctly?

#include "DarkGDK.h"

bool initialize();

void DarkGDK ( void )
{

dbSyncOn   ( );
	dbSyncRate ( 60 );

while ( LoopGDK ( ) )
	{
		if (!initialize()) dbText( 0, 0, "Initializing" );

dbXRotateCamera( dbCameraAngleX()+dbMouseMoveY()/5 );
		dbYRotateCamera( dbCameraAngleY()+dbMouseMoveX()/5 );
		if (dbUpKey()==1) dbMoveCamera( 10 );
		if (dbDownKey()==1) dbMoveCamera(-10 );
		//if (dbLeftKey()==1) dbMoveCameraLeft( 10 );
		//if (dbRightKey()==1) dbMoveCameraRight( 10 );
		dbPositionMouse( 200, 200 );
		
		dbCenterText ( 200,400,"Loading was successful." );
		char msg[250];
		sprintf_s( msg, "Triangle Count: %d", dbStatistic(1) );dbCenterText ( 200,200, msg );
		sprintf_s( msg, "Camera X: %.3f", dbCameraPositionX() );dbCenterText ( 200,220, msg );
		sprintf_s( msg, "Camera Y: %.3f", dbCameraPositionY() );dbCenterText ( 200,240, msg );
		sprintf_s( msg, "Camera Z: %.3f", dbCameraPositionZ() );dbCenterText ( 200,260, msg );

dbSync ( );
	}

return;
}

bool initialize(){
	static bool init_finished=false;
	if (!init_finished){
	dbLoadBitmap( "Cement.png",1);
	dbPrint( "Now Loading..." );
	dbHideMouse();
	//dbMakeCamera(1);
	//dbSetCurrentCamera(1);
	
	dbLoadObject( "meow.x",1 );
	dbSetCurrentBitmap(0);
		init_finished=true;}
	else 
		return true;
}

+ Code Snippet

#include "DarkGDK.h"

bool initialize();


void DarkGDK ( void )
{	

	dbSyncOn   ( );
	dbSyncRate ( 60 );

	
	while ( LoopGDK ( ) )

		//if (dbLeftKey()==1) dbMoveCameraLeft( 10 );
		//if (dbRightKey()==1) dbMoveCameraRight( 10 );
		dbPositionMouse( 200, 200 );
		
		dbCenterText ( 200,400,"Loading was successful." );

		sprintf_s( msg, "Camera X: %.3f", dbCameraPositionX() );dbCenterText ( 200,220, msg );
		sprintf_s( msg, "Camera Y: %.3f", dbCameraPositionY() );dbCenterText ( 200,240, msg );
		sprintf_s( msg, "Camera Z: %.3f", dbCameraPositionZ() );dbCenterText ( 200,260, msg );
		

		dbSync ( );

[First part wrong]

Why don't you do something like this:

#include "DarkGDK.h"

void initialize();

void DarkGDK ( void )
{

dbSyncOn   ( );
	dbSyncRate ( 60 );

initialize(); // Loads everything once.
	
	while ( LoopGDK ( ) )
	{
		dbXRotateCamera( dbCameraAngleX()+dbMouseMoveY()/5 );
		dbYRotateCamera( dbCameraAngleY()+dbMouseMoveX()/5 );
		if (dbUpKey()==1) dbMoveCamera( 10 );
		if (dbDownKey()==1) dbMoveCamera(-10 );
		//if (dbLeftKey()==1) dbMoveCameraLeft( 10 );
		//if (dbRightKey()==1) dbMoveCameraRight( 10 );
		dbPositionMouse( 200, 200 );
		
		dbCenterText ( 200,400,"Loading was successful." );
		char msg[250];
		sprintf_s( msg, "Triangle Count: %d", dbStatistic(1) );dbCenterText ( 200,200, msg );
		sprintf_s( msg, "Camera X: %.3f", dbCameraPositionX() );dbCenterText ( 200,220, msg );
		sprintf_s( msg, "Camera Y: %.3f", dbCameraPositionY() );dbCenterText ( 200,240, msg );
		sprintf_s( msg, "Camera Z: %.3f", dbCameraPositionZ() );dbCenterText ( 200,260, msg );

dbSync ( );
                dbCLS(dbRGB(0, 0, 0)); // Clears screen with black
	}

return;
}

void initialize(){
	dbPrint( "Now Loading..." );
	dbLoadBitmap( "Cement.png",1);
	dbHideMouse();
	//dbMakeCamera(1);
	//dbSetCurrentCamera(1);
	dbLoadObject( "meow.x",1 );
	dbSetCurrentBitmap(0);
        dbSync();
}

+ Code Snippet

#include "DarkGDK.h"

void initialize();

void DarkGDK ( void )
{	

	dbSyncOn   ( );
	dbSyncRate ( 60 );

        initialize(); // Loads everything once.
	
	while ( LoopGDK ( ) )
	{
		dbXRotateCamera( dbCameraAngleX()+dbMouseMoveY()/5 );
		dbYRotateCamera( dbCameraAngleY()+dbMouseMoveX()/5 );
		if (dbUpKey()==1) dbMoveCamera( 10 );
		if (dbDownKey()==1) dbMoveCamera(-10 );
		//if (dbLeftKey()==1) dbMoveCameraLeft( 10 );
		//if (dbRightKey()==1) dbMoveCameraRight( 10 );
		dbPositionMouse( 200, 200 );
		
		dbCenterText ( 200,400,"Loading was successful." );
		char msg[250];
		sprintf_s( msg, "Triangle Count: %d", dbStatistic(1) );dbCenterText ( 200,200, msg );
		sprintf_s( msg, "Camera X: %.3f", dbCameraPositionX() );dbCenterText ( 200,220, msg );
		sprintf_s( msg, "Camera Y: %.3f", dbCameraPositionY() );dbCenterText ( 200,240, msg );
		sprintf_s( msg, "Camera Z: %.3f", dbCameraPositionZ() );dbCenterText ( 200,260, msg );
		

		dbSync ( );
                dbCLS(dbRGB(0, 0, 0)); // Clears screen with black
	}


	return;
}

void initialize(){
	dbPrint( "Now Loading..." );
	dbLoadBitmap( "Cement.png",1);
	dbHideMouse();
	//dbMakeCamera(1);
	//dbSetCurrentCamera(1);
	dbLoadObject( "meow.x",1 );
	dbSetCurrentBitmap(0);
        dbSync();
}

And by the way, if you're only loading a couple of small files like this, it's likely that you won't really see the loading screen because it won't take that much time to load.

Static means it only declares it once, but I don't know if you can only use a variable in a function for one call, or if static keeps it there. If you have a loop and do this:

+ Code Snippet

for(int i = 0; i < 1000; i++)
{
 static int value = 1000;
 value--;
 dbText(0,i*20,dbStr(value));
}

you would not get 999 repeated lots of times, but 999 all the way down to 1

But won't the boolean just reset once it goes out of scope?
And be set to false again? I tested it and it was always false.

Edit: Ahhh you're right. Well, you learn something new everyday.

If I remember correctly, one had to call dbSync twice for the loading screen to show up, because the first call doesn't display, only sets it up.

Ah so it does.. I just checked my code, and sure enough, there is 2 dbSync();

The initialiize() function is a bit dodgy - you are not returning anything on the first call. You should have a return statement inside the if statement.

If you only need to call it once then why put it in the main loop where it will constantly be called? Your best bet would be to call it once before you enter the loop.

+ Code Snippet


void initilize(void);

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

  initialize();

  while ( LoopGDK ( ) )
  {

     etc ..

Of all the things I've lost .. I miss my marbles most of all.

Thank you for the help...

Yeah you're right.hehe

I was thinking ahead of myself. I was thinking of many different initializations for my map levels(as if I have that many..hahaha).

I'm still not sure how to implement initializations of different map levels or areas during gameplay. Thanks.

Thanks for the help guys ^__^
