Rules Discussion / Re: Steep Hill + wall and LoS
« on: November 16, 2017, 12:09:26 AM »If we cross 2 zone borders, steep hill blocks our LoS. We now check our way-set and look for points that meet at least one of 4 criterias:
-its coordinates are (i,x)
-its coordinates are (i+1,x)
-its coordinates are (x,j)
-its coordinates are (x,j+1),
where x doesn't matter.
We find 0, 1 or 2 of those points.
This is how many Zone borders we cross.
0 Zone Borders: LoS doesn't cross Steep hill. Stee Hill doesn't block LoS.
1: LoS goes into the zone with Steep Hill. Steep Hill doesn't block LoS.
OR 1: LoS crosses a corner of the Steep Hill zone. WIll come to this in a second.
2: LoS crosses the Steep Hill zone and Steep Hill blocks LoS.
So, this is where I messed things up.
I totally forgot what the original question was. We want to track LoS to the Zone border itself.
The above number of points does not show hw many Zone borders we cross, it shows how many zone borders we meet. If we stop drawing the line once we meet a zone border, we stilll add one of the above points to our way-set. We do not add any points to our way-set that do belong to another zone.
What does it mean if LoS
Let's count the points again from my quote again, shall we?
0: Stays at it is. No steep hill involved.
1: Stays at it is. Both cases. While the second one still is interesting, it does not answer the original post's question.
(Steep Hill doesn' block LoS to a wall between itself and you either. )
2: Now things get a little more complicated. Finding 2 of those points does for itself not mean passing through two sides of steep hill's zone. To accomplish this you need to find points of at least three zones: Steep hill's zone and two adjacent zones.
If you pass through something, you start at one side of it and end up on the other side.
If you start or end tracking LoS at a zone border, LoS does not pass through it.
To finally answer the question:
Our way-set does not contain points from the zone "behind the wall", therefore LoS does not pass through two sides of Steep Hill's zone. This means the paladin does have LoS to all three walls.
