correct, but i guess i don't see why you'd have to hide a bitmap when you don't see a bitmap? how can you hide something that you can't see? the only bitmap you see is bitmap 0 . bitmaps are the canvas and not the diplay (other than bitmap 0) you only see the image taken from a bitmap, so if you want to hide an image until you want to see it, load it at the begining and then just plug in the conditions that you want to see the image to the code i wrote earier. if you don't want to load the image at the begining, then load it later, but it will cause a delay. if you are seeking sprite priority so that one sprite will be dispalyed over another sprite, there is another post on the board that talks about priority of sprites.
you can delete the spires or images if you will no longer need them or create new sprites any time you want on images already loaded
other than that someone else will have to help ya, unless you post some code or give a more exact discription of what info you are seeking
hope it helps
