Scroll Down Logic Problem

[junkatana]

I have some problem when set scroll to Down, because start at the end of map. I know that's the problem can be my logic, so, what is the best way approach to user scroll DOWN?

My code bellow:



Dim FullMap(39, 55) as Integer

pallettes map_color, 1, 0, 16
´load pallette from map_color
loadtiles map_tile, 139, 273
´load from map tiles

reload map ´tilemap

for mY=0 to 55

for mX=0 to 39

readint FullMap(mX, mY)

next mX

next mY



for mY=0 to 55

for mX=0 to 39

drawtile FullMap(mX, mY)+pallette(1)+273,mX, mY

next mX

next mY



setscrollmode HSCROLL_OVERALL, VSCROLL_OVERALL

       do
       scroll DOWN, 1
       loop

Kind of hard to troubleshoot when you don't really say what the problem is

First, you don't need 2 sets of loops. Just draw the tile to the plane in the same loop since you already pulled the value with ReadInt.

Second, you don't need to set the scroll mode to overall on either the horizontal or vertical scroll, unless you had changed it previously, as that's the default scroll mode.

Next, try putting "Sleep 1" after the scroll command.

Then, tell us what issue you're having, or toss up the entire source so we can see exactly what you're seeing (I didn't see any tile data in your post, but that could be my phones fault).

Sorry about that and thanks for tips. So the big problem is, when the map scroll down, start at the end of my scene. I need start at the bottom, where is my start scene. Sorry about my english. Can you understand me?

I think I get what you're saying. You want the screen to start at the very bottom?


   scroll2 down, 224 ' 240 if you're in PAL mode


What Scroll2 does is scrolls the plane to that location. You could also do: Scroll down,224 (not in a loop) and this will scroll the plane by 224 pixels in 1 jump, relative to where the position currently is (ie, if you scrolled down 6, then did a 224, the plane would be at x = 224). Scroll2 puts the plane at that exact location, regardless of its current position, so Scroll2 puts the plane at x = 224, even if it were previously at x = 50.

You'll want to scroll "up" with a loop if you want it to scroll on screen.

I hope that helps!

Help so much elusive, thank you.
