Is it possible to create a wall-embedded object that actually makes a passage through the wall?
What I mean is an element that you embed in the wall and which actually removes the voxel it is embedded into.
I tried it a bit, but I couldn't figure out how to 1. have the puzzlemaker not create metal embed-walls inside the embedding square and 2. remove the back wall surface.
As for changing antline attachments without changing the element, I tried altering the antline coordinates and positions a bit, but the best I could make is signages that are "floating" up in air beside the door, but they are still facing up as if they were on the floor. Looks like the editor doesn't support changing the plane of signages.
Yes, one solution (that I really often use) is to put Ben's Logic AND elements on the walls right inside the same square where the door is standing, and connect the antlines into those AND elements. However, when you want to have some antlines going to the front, some to the left, some to the right, there is inconsistency, if some of them don't include "X" symbol that comes only when multiple antlines connect to the same target. If you have four connections, one going to the left side (AND element), one to the right side (another AND element), and two going to the front (door itself), you get X'es on the two going to the front, but not on the ones going to the sides.
Hmm... What if there was an invisible logic connection element that could be placed next to the door, i.e. on its left side or its right side, which would be "embedded" on the wall on the side of the door, standing on the wall surface much like the Portal Magnet or the Flip Panel, but instead of rendering its signages around the element itself, the signages would be offset by one wall-unit, i.e. it would render its signages around the next element -- around the door? Could this work?
Or does the editor have a restriction that the signages cannot be offseted too far off? Earlier I tried making six parallel signage points in front of the door on the floor, but any signages I tried placing on the floor that were not directly in front of the door (i.e. they were diagonally ahead from the door), caused the editor to crash...
