Twice in one night. Ok I am haing a problem with dbSprite.



The sprite appears in the right place it is just streatched really large. I am scratching my head trying to figure out why placing my sprite is causing it to streatch.

Could spos be getting calculated to be out of bounds of the current screen area ? do sprites "wrap" around if you do that with their co-ords ?

I mean, provide 1 co-ord that is inside screen area, and one that is outside(ie negative) ... could that be the cause of your sprite warping ?

I havent done alot with sprites so im not 100% sure of their behaviour in that kind of situation, but the sprite command doesnt look like alot can go wrong with it really, a sprite number, 2 co-ords and an image number...

Your image isnt being corrupted at all somewhere along the line ?

just thinking out loud... good luck, thats a strange one for sure lol

If it ain't broke.... DONT FIX IT !!!

Yeah I am not sure...

Well I think it has something to do with the create animated sprite function. I am using an image 800x1580, 1x20 frames. When I call dbSprite it sets the sprite to frame one and scales it to the size of the image (800x1580)

ahhh yep that would be correct, I think with sprites you can change their UV co-ords can you ? if you want to use jsut a part of an image for the sprite...



Also, you can use dbPasteSprite, to paste an existing sprite to a new position, rather than create a new one which is what dbSprite does.

Have a look through the DarkSDKSprites.h header files, there are a few interesting commands in there.

EDIT : you would need to call that command 4 times to keep the sprite square, a sprite has 4 vertices.... top left, top right, bottom left and bottom right....

If it ain't broke.... DONT FIX IT !!!

I am just setting the sprite up right now. I hate the fact that the documentation is so vague about everything.
