I seem to be having problems displaying a large sprite.
The size is 256x2085. I am then scaling 2*Width before displaying but all I seem to get is a white sprite. Any ideas?



The sprite png is definitely in the asset folder and named correctly, I tested it with a smaller 128*128 pixel sprite and it works correctly then..

Sprites can be just about any size I think but your images should be no larger than 2048 for some platforms and 1024 for others, otherwise you get this problem.

Due to the limits of mobile devices (and depending on the graphics chip) any image with either dimension greater than 1024 has a chance of becoming a 'white' sprite (it might display correctly on some devices). So, to be on the safe side, keep your images below or equal to 1024x1024.

Thanks baxslash and Hodgey,

Looks like I'll have to think again about my map layout for this PB game, grrr,

Aha, what would be handy is a command to link sprites, so that wherever the first sprite is moved to then the second would be moved next to it (offset). I'm sure I can knock up a quick little routine to mimic it,

EDIT: Just tested and 2048px in height seems to be ok, so I'll just stitch three sprites together to get a nice and high 512*6144 level,

You could link sprites easily using an array:

Ahh, nice baxslash, saves me writing it, it's easy enough to convert to c++,

No problem. Might need some adjustment to suit your needs
