Day 5: Areas/filters/furre present
So, you're hopefully itching to do more advanced
stuff. Cause you get to do powerful things today: Areas, filters,
and moving furres present. This is where the true mind of the
programmer comes in. Ok, now add this to your map outside:

Make sure that when you select the water floor, it says "walk:y" below
the floor. If not, it won't work.
Ok, now put this in your ds.
River
(0:100) When 1 seconds
have passed, offset by 1,
(3:4) within the rectangle (12,14) - (16,21),
(4:8) only where there
are no objects,
(5:81) move any furre present 1
step(s) southeast (down and right) if there's nobody already there.
Now, be sure to set the first position in the rectangle to the
top-left corner in the river and the second to the bottom-right.
If you did it right, people should be able to sit on the rock without
"drifting".
Ok, that's all for today.
