I am looking for a way to rotate a sprite around the center of the sprite 360 degrees.

I know there is a rotate sprite command, but it rotates around the top left.

Any help would be appreciated.

Later all, and thanks.

wow this is an easy one..

just get the size of your sprite and when you rotate it offset it by half that on the x and y.

Use 'dbOffsetSprite()' to offset it by half its size, that'll change the origin to the center.

dbOffsetSprite(spritenum, dbSpriteWidth(spritenum)/2, dbSpriteHeight(spritenum)/2);

OMG, that works, but I swear that I tried that before!!! oh well.

So first you dbOffsetSprite (etc)
then you dbRotateSprite ( etc )!!!

and you have to keep track of the rotation and keep advancing it, because the sprite itself does not have that as an internal variable.

So, the call the dbRotateSprite ( spritenum, rotation );

and rotation is a float.

thanks guys, this is getting better and better.

more later,

jeff
