Rooftop LOS question

[bendizoid]

Me and Paul are playing Hueishan Docks and Rooftops are in play. Can a unit on a rooftop in a building with ground and first level see over single story houses or woods and shoot units on ground level?

 

[Mr Incredible]

"Rooftops are treated the same as another building floor level at the next higher half-level elevation........."

So that half level allows you to see over single storey houses (One level obstacles) but not two storey houses that are 1.5 level obstacles with their pesky roof pitches in the way.

 

[bendizoid]

I say you can't see over 1st level obstacles from a 1st level rooftop. Paul thinks you can. I can't find the rule. Been reading the f***ing rulebook for an hour now and I can't find it.

The Level of the rooftop on a building with a Ground and Level 1 is at Level 1.5 and can thusly see over Level 1 obstacles.

A building with only a ground level has a rooftop at ½ level above its highest level (level zero), i.e. at level ½. This would be a problem (of sorts), but per SSR 1 only multi-hex buildings have rooftops. A multi-hex building without a stairwell has level zero and level one locations, which puts the rooftop (and units on it) at level one-and-one-half. A multi-hex building with stairwells has level zero, one and two locations, which means the rooftop in them is at level two-and-one-half. You should have no 1st level rooftops, i.e. rooftops at level one.

Per A6.4 a unit that is any amount higher than a full-level obstacle can see past that obstacle to a lower level but with a certain number of blind hexes. A unit at level one-and-one-half (on a rooftop of a multi-hex building without a stairwell) can see past a level one obstacle (a single-story house, a woods, etc) to ground level with one blind hex when the obstacle is at range 1-4.

There is a building with two hexes. It has a ground level , a 1st level and a rooftop. Can a unit on a rooftop there see over a 1 level woods?




The rooftop is at level 1 1/2. Can it see over a level one obstacle to ground level?

 

[jrv]

Omg, there is a building with two hexs. It has a ground, 1st level and a rooftop. Can a unit on a rooftop there see over a 1 level woods?

A unit on the rooftop is at level one-and-one-half. It is higher than any level one obstacle and may see over such an obstacle to a lower-level location as long as that lower-level location is not in a blind hex.

Thank you very much, that changes everything.

 

[Mister T]

Learnt that when playing RB twenty years ago, very useful in that specific context.

I just checked my car. The oil still needs changing. Is "everything" in this context metaphorical?

I played RB twenty years ago and thought the opposite. We thought you needed a full level to see over.

 

[clubby]

Needing a full level would really put a spike in slopes.

JR

No.

If there weren't a LOS from the Rooftop in the described situation, the oil of your car would already have been changed by now.

[MajorDomo]

Yep, it can see over.

Another ASL oddity occurs with 2 1/2 level rooftops.
A unit in the second floor of a building has the same number of blind hexes as a unit on the roof of the same building when looking over a single story building.

Fixing a roof tile on my friend's roof last week made this laughable.

Blind half hexes would be complicated to apply.

That might be correct for a Two Storey House (B23.22), which is a 1.5 level obstacle, but not a Single Storey House (B23.21) which is a 1 level obstacle.

I'm not sure what you think is incorrect. Per the SSR only multi-hex buildings have rooftops. Per the rules, multi-hex buildings are never single-storey houses [B23.21]. No single-storey building has a rooftop in this scenario by SSR. Also per B23.8, no single-storey house has a rooftop in general. You cannot be on a rooftop on a single-storey house. The lowest you can be on a rooftop is in a two-storey house, and that puts you at level 1.5. Which part do you think is wrong?

Would it have the same number of blind hexes as a unit at rooftop 1 1/2?

 

[Eagle4ty]

Yes, the half level is ignored for the calculation (A6.21 & A6.4).

 

[clubby]

Yes, the half level is ignored for the calculation (A6.21 & A6.4).

Compared to your example, wouldn't a unit on the 1 1/2 level rooftop have one more blind hex than the unit on the 2 1/2 level rooftop?
