So, I had this idea of a gun that creates walls, is it possible to make one? and is it possible to make the walls settle as not-scrap?

First part, yes you can make walls. Second part, not at this time. Or at least, not to my knowledge. I tried it but it did not work.
You can, however, make a MOSRotating that doesn't settle for a wall. Actors won't like being crushed against it and may wig out, but it works just fine on projectiles.

OK I managed to make a throwable wall, the only drawback is that it settles to scrap :S And I want it to settle to something more reliable than that

-snip-

just creative thinking wouldn't it be possible to make something like the old and dusty concrete thrower only it sprays at a much more rapid rate, or it would lauch blocks or walls because I dont know about a gun shooting walls maybe a tool would be better suited. I've seen a debris ssprayer and its the stronger type not the wimpy type.

Have the material be concrete and it should work fine. (I hope)

I actually made a throwable block that becomes a wall upon contact, it still settles scrap, you can find it in my FC mini-faction around this section.

@numgun - still scrap

What, exactly, is so horrible about a wall settling into terrain?

This part, specifically settling into a scrap material. Shoot into it, and all along your line for 12 pixels above the rest of the scrap terrain is destroyed.

the problem is that IsScrap = 0 only works if there is background behind the object. im thinking of making a proper wall gun with emitters, MOSRs as a base and MOSPs for some deviation. i'll probably make it with ice sprites.. i'd be tempted to make the things with attachables so it would gib and fall over and it would be cool and all but i cant be assed at the moment
