So I've embarked on my second program with the Dark GDK. It's been going great so far. What I've got now is a screen with a background, and clouds floating by. The problem is that when I add a animated sprite one of the clouds just stays at one point. When I take the code for the animated Sprite out, everything works fine.

Before animated sprite code:

+ Code Snippet

 #include "DarkGDK.h"


void DarkGDK ( void )
{
	int k = -1150; // I is the x Coordinate used below
	int a = -1200;
	int b = -800;
	int c = -300;

	
	dbSyncOn   ( );
	dbSyncRate ( 60 );

dbSetImageColorKey ( 255, 0, 255 );

	dbLoadImage ( "fishbackgroundfinal2.bmp", 1);
	dbLoadImage ( "land.bmp", 6);
	dbLoadImage ( "cloud.bmp", 7);
	dbLoadImage ( "cloud2.bmp", 3);
	dbLoadImage ( "cloud3.bmp", 4);
	dbLoadImage ( "cloud4.bmp", 5);

	while ( LoopGDK ( ) )
	{
		dbSprite (1, 0, 0, 1);
		
		//water Start 
//nothing to see here 
//water End

//Cloud Start

		dbSprite (7, k, 25, 7);
		k++;
	if(k == 700)
		{
			k = -550;
		}

		dbSprite (3, a, 7, 3);
		a++;
		a++;
	if (a == 1500)
	{
		a = -500;
	}

dbSprite(4, b, 35, 4); 
b++;
if (b == 900)
{
	b = -300;
}
dbSprite(5, c, 30, 5);
c++;
if (c == 650)
{
	c = -350;
}

//Cloud End



dbSprite (6, 0, 180, 6);

		dbSync ( );
	}

	
	return;
}

With animated Sprite code:

+ Code Snippet

#include "DarkGDK.h"


void DarkGDK ( void )
{
	int k = -1150; // I is the x Coordinate used below
	int a = -1200;
	int b = -800;
	int c = -300;

	
	dbSyncOn   ( );
	dbSyncRate ( 60 );

dbSetImageColorKey ( 255, 0, 255 );

	dbLoadImage ( "fishbackgroundfinal2.bmp", 1);
	dbLoadImage ( "land.bmp", 6);
	dbLoadImage ( "cloud.bmp", 7);
	dbLoadImage ( "cloud2.bmp", 3);
	dbLoadImage ( "cloud3.bmp", 4);
	dbLoadImage ( "cloud4.bmp", 5);

	while ( LoopGDK ( ) )
	{
		dbSprite (1, 0, 0, 1);
		
		//water Start 
dbCreateAnimatedSprite(10, "water1.bmp", 1, 6, 10);
dbSprite(10, 265, 380, 10);
dbPlaySprite(10, 1, 6, 300);
//water End

//Cloud Start

		dbSprite (7, k, 25, 7);
		k++;
	if(k == 700)
		{
			k = -550;
		}

		dbSprite (3, a, 7, 3);
		a++;
		a++;
	if (a == 1500)
	{
		a = -500;
	}

dbSprite(4, b, 35, 4); 
b++;
if (b == 900)
{
	b = -300;
}
dbSprite(5, c, 30, 5);
c++;
if (c == 650)
{
	c = -350;
}

//Cloud End



dbSprite (6, 0, 180, 6);

		dbSync ( );
	}

	
	return;
}

Any help? Thanks!

there are a couple of things wrong with this.
first off, create your animated sprite outside of LoopGDK. this is basically loading the sprite every cycle, and is not good practice. when you play the sprite, it has an incredibly high delay, so lower that to say, less than 25. also, this wouldn't create problems for the program, but its better to use words than single characters for variable names. it would be even better if you had them in an array.
for example, replace k,a,b,c with "int CloudX[4] = {-1150, -1200, -800, -300};", and access it with "CloudX[/*number here*/]" with k's number being 0, a's 1, b's 2, and c's 3. also, you do not need to use dbSprite inside the while loop. if the object is not moving.

-to the optimist, the glass is half full. to the pessimist, it is half empty, to the engineer, it is twice as big as it needs to be.

Thanks for your response bloodmage. I have, in fact, fixed my problem. I have my animated sprite over a moving background. At this point I have run into a new problem. It would be great if you could check it out here. Hopefully you'll have some advice.

Thanks for everything!
