[FakeTruth]

I now need to do a "distance fro a point to a line" and I'm kinda rusty. Shame on me, really.

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 I suck at vector math

[xoft]

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 travel 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.

[xoft]

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.

[xoft]

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.

[NiLSPACE]

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:
   

[FakeTruth]

Looks good for teletubby landscape

[Taugeshtu]

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

One more day in new zealand, then two more days in south korea. And then finally back home.
