Can all seige shoot through walls

[Cynn Thfkn Ninja]

Title, not sure if they do or not, it feels like they do whether friendly or enemy walls/gates.

[Falaris]

All shoot past palisades just fine.
Trebuchets and mangonels shoot past stone walls, but not springalds and cannons.

(This is what I have seen so far, but I may be wrong.).

[General Oliver]

mangonels can shoot over walls, just dont place them to close, because the projectile will it the wall. springalds and cannons can shoot through gates. but i don't think enemy cannons and springalds can shoot back, haven't seen it and plan on testing it this weekend. not sure on palisades, but cannons cant shoot through fortified palisades.

[Heimdall313]

Low trajectory can't shoot over stone walls. Cannons and springald.
Trebs and mangonels can shoot high angles, over walls.

I haven't taken cannons to Palisades but I imagine they blow down wooden fences pretty easy
