What would be used as a visual indicator of such walls?
Hmm. This is a tough one.
My initial instinct is some sort of crossed-out bomb graphic which flashes on and off (dotted across the field in place of OWW arrows). I'd look at designing such a graphic in low-res first, to make sure it looks good with less pixels before beefing it up for high-res.
Another idea could be a 4-frame animation of an explosion (again, dotted across the field where the arrows of a OWW would usually be), but this could be potentially confusing, implying that
only Bombers/Bombs can destroy the wall.
One to brainstorm, I think.
Do we want a "flavourful" depiction, like with steel (in-game reason why it can't be destroyed)
Interesting, I hadn't thought of that at first. But sure, another in-game material with a distinctive look could work. I'd suggest it be some sort of soft and gooey stuff, like plasticine. It would repel a blast from a Bomber, but other destructive skills could conceivably work their way through it.
The obvious problem is the sheer number of ways it could be depicted. If terrain could be animated, maybe making it look liquidy could work...?
THOUGHT: There is a waxy graphic in Lix which could work really well for this, actually:
If these would indeed work like a 5th type of one-way wall, I'm leaning towards a game-mechanical indicator, like the Bomber's explosion animation ("star-shaped") with a crossed-out symbol on top of it or so
Well, that's two mentions for this, so maybe it's the obvious way to go.
if we get bombs/detonators (I personally hear about them for the first time now), they should work the same way as bombers
+1, absolutely agree with this.
