How does this command work?
It does not do what i expect it to.
does it take into account the orrigional position of the sprite.
why do positive numbers display the sprite off screen, while negative x and y offset it on screen but not by the values you set.
how do you use this command?

Some days the cascading moments which constitute my experience dissolve to reveal a sense of clarity which transcends reasoning.
And then there are days like today.

read the help:
Quote: "
dbOffsetSprite
This command will shift the position of the drawn image without affecting the coordinate of the specified sprite. You can use this command to change the visible sprite in relation to the coordinates you use to position it.

Syntax
void dbOffsetSprite ( int iSprite, int iX, int iY )

edit: or did you know that already?

Has anyone used this command before?
Well its wack.

I just figured out that i should use dbSprite to position sprites so i guess i didnt need it anyway.

Thanks though.

I never used it but I think it works this way:

-you position your sprite at 10, 10
-It will show at 10, 10

-you set dbOffsetSprite 1,1
-you position your sprite at 10, 10
-It will show at 11, 11

May this helps, though, I didnt tried that commands...

Smithy you are pretty much right

dbOffsetSprite is so that you can set the "anchor point" of the sprite for like rotations and stuff.

int deg=0;
dbOffsetSprite (1, dbSpriteWidth()/2, dbSpriteHeight/2);
dbRotateSprite(1,++deg);

and now it will spin around the center instead of around the top left corner.

That's useful, another peice of information. I remeber writing a rotating "missile" in DBpro I had not got around to figuring out how to change it's offset. This will help me out allot thanks!
