[VN Boards Archive]

Welcome to the Vault Network forum archive.

This is not a complete archive, time didn't allot us the opportunity to properly backup the majority of the boards deemed "expendable". Most boards on this list have at least 20-40 pages archived (non-logged in pages, 15 topics per page).

Popular boards may have as many as 250 pages archived at 50 topics per page, while others deemed of historical signifigance may be archived in their entirety.

We may not agree with how the board shutdown was managed, but we've done what we could to preserve some of its history in lieu of that.

Please enjoy the archive.

Topic: Distance in AC

	Old question, but how to calculate distance in AC across landblock boundaries? These formules give heading & distance WITHIN a landblock: EW1 = (Target EW) - (my EW loc) NS1 = (Target NS) - (my NS loc) distance = sqrt(sqr(NS1) + sqr(EW1)) Heading = ARCTAN(EW1/ NS1) * ( 180 / PI ) (ElgarL) But if the start and end locations are in two different landblocks, how does one navigate? Do you first do a calc to the target landblock, and then switch to X,Y coordinates to navigate to the desired location? Or is there a trig formula that will give a heading and distance? The map in AC is made up as follows: - landblocks are 88 squares - squares are 2424 units - world is 255255 landblocks (20402040 squares) - center (in squares) is at 1020,1020 - the divide by 10 was a nice scaling factor which seems to give the right results (matches ac's map coords after rounding to one decimal place) - For outdoors, the lower 7 bits of the landblock value represent which of the 64 squares within the landblock you are standing on. The value is 1 in the south west corner of the landblock, 8 in the north west corner, 57 in the south east corner and 64 in the north east corner (ie. count each column south to north). Not sure why they didn't have the south west corner as zero, could have saved a bit. (antishreth) -----signature----- Chazcon - Aluvian swordsman You say, "FOR THE VITAE!" Ru tells you, "CHAZ!"

	WorldFilter has a method that will take two different objects and calculate the distance between them. IIRC correctly, it has a method you can give coords to as well. That is easiest/best way. -----signature-----
