Thanks for last time, everybody. Now, I have been able to compile a Hello World! Anyway, after I tried creating a new project, it's not working, but giving me different errors...

You have one level Right? 2 thru whatever don't exsist yet... comment out the code that references those until you are ready to fill in the blanks.

that's my first stab based on recalling your posts elsewhere and the linker message.

Ah yes! Thanks for saying that.... I didn't notice. Thanks again jason!

By the way, is there any DGDK function that moves the sprite's X or Y?

Just wondering...

To the best of my knowledge you just enter the dbSprite function again with the new coordinates and referencing the same image.

Another option is to rotate the sprite and then issue a move command

Quote: "
This command will move the sprite a specified distance. Used in combination with the dbRotateSprite command a very simple top-down player character can be achieved very easily.

Syntax
void dbMoveSprite ( int iNUmber, float fVelocity )

@Lilith: Thanks, I'll try that!
@Codger: as I couldn't find any iNUmber references on the sprites page, I assumed it was for 3d sprites...

@Charles Black

The iNumber simply repesent the integer value of the sprite. I posted this code earlier for lilith hopefully it will clarify sprites a little

+ Code Snippet

#include "DarkGDK.h"
float angle;
// the main entry point for the application is this function
void DarkGDK ( void ){ 
  dbSyncOn();
  dbInk(dbRGB(255,0,0),dbRGB(0,0,0));
  dbBox(0,0,100,100);
  dbInk(dbRGB(255,255,255),0);
  dbBox(10,10,90,90);
  dbSync(); dbSync();
  dbGetImage(1,0,0,100,100);
  dbSprite(1,200,200,1);
  dbCLS();
  while ( LoopGDK ( ) ){
	  dbMoveSprite(1,5);
	  dbRotateSprite(1,angle++);
    dbSync();
  };
};
