Description

Let's say there's a monster in some trap sector that is raised up. The floor of this trap sector is set to the same height as the ceiling of the surrounding sector. Player can't see the monster and neither should the monster see player. But the monster is able to see player. Then the monster starts attacking player.

The same happens if it was player that was in a similar sector, like in Plutonia Map 04: Caged.

Monsters don't see through doors, so it's not like they see through every 2 sided line...

History

#1 Updated by danij over 12 years ago

Fixed for 1.9.0-beta6.8

#2 Updated by eklipse2009 over 12 years ago

Same for me, also in Heretic in all the maps.

#3 Updated by vermil over 12 years ago

I would like to request that this report be re-opened as the bug still exists to at least some degree.

For instance, in Doom E3M1 the Imp's in the start area wake up as soon as the map starts and proceed to try to attack you through the ground.

You are indeed correct, the following case was not handled correctly:

LOS from src to dest intersects a linedef bisecting two sectors where the floor on the src side is greater than that on the backside

The in-range test was done vs the back floor rather than the front.

Fixed for 1.9.0-beta6.9
