actually what i think you mean is can you hide an image
you can only have 30 or 31 bitmaps, but you can have almost limitless images (the more you have the slower it goes)
a bitmap is like a pallet or canvas that you paint on an image is something you display
i don't think you can hide an image but you can hide a sprite
well i created a basic room with objects and a dude walkin around in about 3hrs so it has the power and its pretty easy to use the basics, its just...... well its hard to get it to look as good as those people who are really good and then art work is always a prob, but half the fun of it is the quest. i can buy an adventure or i can live one and maybe even some day make one
My advice is free -
unfortunately you get what you pay for (-:
