First dot the point vector with the line direction, this gives you a scalar, then multiply that scalar with the normalized line direction to get the projected point.

Code:
Global point pos: P
Line point 1: L1
Line point 2: L2

Projected point: pP = dot( P - (L2-L1), normalizecpy( L2-L1 ) ) * normalizecpy( L2-L1 )
Distance = length( pP - P )

At least I THINK that's how it went Sad I suck at vector math
Thanks given by:
Yeah, but I mean line as only between two points, so it's either the distance to the straight line, or to the edge points, whichever is closer. Not to mention I need to interpolate a few parameters based on the projected point's position on the line segment... I need to draw this on a paper, which is kinda tricky now, normally one doesn't bring a lot of paper to a vacation travelTongue Especially when backpacking.

STR, yeah, the gens branch isn't meant to be in top condition and may not compile; I have had already some more changes when I was committing it, so it might be uncompilable as it is in svn. It's more or less just a backup, so that I don't lose the work if, god forbid, my laptop dies.

Gens branch in rev 1154 compiles fine for me, what error message are you getting?
Note that sometimes VS gets confused if you switch to a different branch, you need to rebuild the whole solution.
Thanks given by:
Added yet another generator in rev 1155; still work in progress, still it generates only height and only very crude. Not worth checking out, really. On the positive side, though, I think it could be integrated later into the Composable generator scheme, simply as a height generator for Extreme hills.

it doesn't compile in release mode. with a .bat file i made a log:

Fixed.

The RoughHillsGenerator isn't going as good as I hoped for, I'm feeling a bit like giving it up altogether. I cannot make the hills any other shapes than "rooftops". If I try any kind of rounding, it produces funky shapes when interpolating:

Looks good for teletubby landscapeBig Grin

Trying to finish Trady. Currently it needs tiny bit of love with "no chest, correct sign" case and not-creating/deleting shop data in case of chest/sign being broken.
Also, awaiting for this to be fixed
