are adaptable items possible?

[bab-cat-OWO]

what I mean are items that change depending on the environment.
simular to the old cutout, goop or vactubes witch change depending on the items/blocks around them?

Depends on what you mean exactly, because this could be almost anything. There's condition flags for orientation, measuring which voxels are occupied, and also the 'marker' mechanism for detecting other items. But the ones you mentioned are all special cased in the compiler. For that sort of thing, I do try to keep the functionality reusable, so you could define your own vactube item, but it'd mostly behave the same as the original. But if you have an idea for a different variant or something, definitely open to adding the options necessary.

ah ok how dose the 'marker' mechanism work along with the condition flags?
