Impassable obstacle

[HobbesACW]

Hi chaps, I'm confused by areas of terrain that show a tooltip of impassable obstacle. Apparently it blocks movement but it doesn't. I moved into the hex shown.
Screenshot from the Battle of Pavia. I've tried a few tests and I can always move into these locations in this scenario. + why would it say an assault would be risky if you can't fire or move into the hex - an assault would be impossible. Is shooting blocked as the tooltip states?
I'm sure I played one scenario where I couldn't move a unit that was surrounded by this type of terrain but it doesn't seem to be the case here.
Thanks for any clarification.

This is Paul59's Pavia not the vanilla one? Heavy fortifications cannot be impassable to foot otherwise they could not be attacked. In the vanilla Pavia, an impassable moat was used to stop most of the walls being accessible.

The tooltip only reports the worst obstacle on the tile. An impassable object only prevent access to the tile across the tile edge it occupies.

There is a "high wall" object that counts as impassable. Heavy forts don't for the above reason. I suspect there may be a high wall object on that tile, perhaps superimposed by a heavy fort object so it cannot be seen.

Yes it is Pauls version.

Thanks,

I have noticed this tool tip appear several times. I am not really sure why it appears, although obviously it is something to do with walls of all types. Although strangely it does not appear in all cases. Here is a screenshot of it next to High and low walls. The battle is Warlord's Fleurus scenario;



Here is a screenshot of a another wall bounded square of my Pavia battlefield that shows a different tool tip, no mention of impassable or blocking;



I have noticed that these impassable squares do block firing through them, at least in some circumstances.

So what is going on here, what are the circumstances in which this tool tip appears?

*Edit- Sorry Richard, you seem to have edited your post above, and it now answers my question.

As I say, it is exclusively the "HighWall" linear object that is impassable. (See line 146ff of ObstacleTools.bsf)

This was put in specifically to represent the estate wall at Pavia, which apparently could not be crossed except where the Imperialists broke through it.

The tooltip will report impassable object for any tile that has one or more sides with a high wall.

Heavy Fortifications, paradoxically, though obviously much larger, do not show that tooltip because they have to be passable in order to be assaultable. That can be made impossible by putting an impassable water-filled moat in front of them.

Sorry Richard, it took me a long time to write my last post (I was interrupted several times), and meanwhile you seem to have edited your first post and answered my question!

One thing still puzzles me though, you say that the High Wall object makes the square impassable across that side, yet I am sure that I have seen units cross High walls. When I get a chance I will create a quick test scenario to confirm this.

I have modified my Knockdoe scenario to test the High walls.

In this first screenshot you can see an Irish infantry unit, and the overlay indicates that it can move into the walled square, even though the tool tip says that it is impassable;



This next shot shows the same thing for a cavalry unit;



The last shot shows both units occupying the walled squares after moving into them;

Hmm. I have a feeling that something may have been changed at some point so that blocking objects block LOS but not movement.

The easiest way to avoid these issues is not to use the high wall object!
