here's my solution to region problems, I made the format accept regular numbers, as well as coords, it's reverse compatable with the old version

Format:
asss region file version 2
;use TILES not pixels

name: MyRegion
;load a rectangle with x=50, y=65, w=90, h=90 TILES
50, 100, 90, 90
; load a coordinate with x=512 y=512
512, 512
isbase

name: YourRegion
50,50
90,50
63,123,4,5

i don't think grel wants it to be official because he thinks using a sparse array for regions would work better... I say that just prevents overlapping regions

The region file I will be converting has some 45 degree walls in it, so there is no way I can really do the file by hand, no matter the format.

Getting off topic here. Perhaps split this off into a new post?

Perhaps a polygon type object would be better... and you could define a series of points like

54,13:15,28:600,512:54,10

and it would make a polygon like that and then check for containment appropriately (draw a ray from your point in any direction, odd number of line intersections = inside polygon, even number of line intersections = outside polygon)

The best way is to have an LVL editor where you can indicate regions visually and save them to a file that ASSS can load. Trying to have users define polygonal or curved regions would cause all kinds of problems with "aliasing".

Best way aside, I need to make a region file. We can talk about what's nice all day long, but the fact of the matter is that I'll have to make a BMP converter.

Polygons also add ambiguity. Don't know for sure if the tiles right on the edge are inside or out. Rectangles you always know.

you just said you wanted 45 degree angles. Wouldn't that add the same ambiguity?

Maybe you could make up a region from horizontal lines, and use some RLE method for the y axis:
; rectangle (5,10) (20,15)
;<how many times to repeat/increment y-coord>:<start y>,<start x>,<end x>
5:10,5,20

No, I said that because of the map's 45 degree angles, I can't make the file by hand. Far too tedious and prone to error.

If I were to only make the file once, I would use Excel to do it, but because there are always changes and additions needed, I will make the conveter sometime this or next week.
