element pressure blocking abilities?
-
Ive been wondering what different elements pressure blocking abilities are. obviously, titanium has the highest, but of the solids what has the lowest? of the liquids what has the highest/lowest? of the gases what has the highest/lowest? It frustrates me slightly because each element has an "Acid desolve rate" but not a "pressure blocking" or "air resistance" (if air resistance is even the right term...) and I keep building stuff that needs a solid wall that blocks particles but lets as much air through as possible, and I dont like using the "walls" tab because they are indestructable and less precise. I would be nice if it was included on the wiki, but I understand if its too complicated.

I just checked the code on github, as far as I can see TTAN is the only element that updates two special arrays in the simulation called map_blockair[y][x] and map_blockairh[y][x], so the pressure blocking is a hand-coded property of TTAN that no other element has.

I did some experementing on my own and it seems some solids have better pressure blocking than others, an example is that shield lets through more air than wood. I dont know the exact rates, but I can tell there is a difference. this difference is mainly what im talking about

Ah okay, that's the AirLoss element property, it sets how much a particle of that element slows down moving air it touches. You can look those up in the console:
elements.property(tpt.element("<element name>"), "AirLoss")
where <element name> is something like WOOD or SHLD.
The returned value is between 0 and 1, 1 means no slowdown, 0 means maximal slowdown.
elements.property(tpt.element("WOOD"), "AirLoss") 0.89999997615814
elements.property(tpt.element("SHLD"), "AirLoss") 1
