[Resolved]Help with Windows, Viewports and Bitmaps

[Zymgo]

Ok, I pretty much understand Scenes and Windows. What I am trying to do is create an area in my scene (in a window? or is it a window itself?) that is 100 x 100 pixels, that i can show a piece of a 100 x 500 image. The position of the 100x100 will change vertically (scroll) in the larger image as necessary (does that make sense?).

Im just not sure how to accomplish this. Do I use a viewport here? I dont really understand viewports. Do I create a window 100x100 and copy a 100x100 section from the big image? Im not familiar enough with RGSS yet to know how to do this. Im using the SDK and MACL. I notice in the MACL there is a method crop_blt for the bitmap class, is that what Im looking for??

Many Thanks

Use the plane class. The plane class is like Sprite, but you initialize a viewport and it tiles the bitmap there.

object = Plane.new(Viewport.new(x, y, width, height))
object.bitmap = BITMAP

In your update method, use

object.ox   +-*/%=   x
# and / or
object.oy   +-*/%=   x

Replace the x, y, width, height with the area you want it to be displayed on, BITMAP with a loaded bitmap (such as RPG::Cache.picture('filename'))

Then just replace +-*/%= with something like += 5
