"Jumpy" Plane rewrites

[Taylor]

So I'm using a script to alter the resolution of one of my games to be 853x480. A 16:9 equivalent to 640x480. However it seems that Plane is bound to 640x480, so I go looking for Plane rewrites.

All the version I've found make my planes either "jumpy" or too fast. I use a timer to slow down the fog effect on my title screen (update_fog1 if @fogup == 3), but this makes the panning clearly pausing between updates. Removing it makes them pan far too fast.

I am currently using this rewrite by Selwyn

PHP Code:

   if @sprite.bitmap != nil

 @sprite.bitmap.dispose

   end

   @sprite.bitmap = Bitmap.new(w * 2, h * 2)

 

   max_x = w / @bitmap.width

   max_y = h / @bitmap.height

   for x in 0..max_x

 for y in 0..max_y

   @sprite.bitmap.blt(x * @bitmap.width, y * @bitmap.height,

    @bitmap, Rect.new(0, 0, @bitmap.width, @bitmap.height))

 end

   end

   for i in 1...4

 x = i % 2 * w

 y = i / 2 * h

 @sprite.bitmap.blt(x, y, @sprite.bitmap, Rect.new(0, 0, w, h))

   end

 end
