We're using a normal wooden side texture to draw the sides
of trapdoors. But the side textures have only 2 edges that
have a nice texture for the 2px wide trapdoor. We can
either repaint the textures, or just rotate the texture
properly for the two sides that need it.
Because the side texture for wooden doors was just a default:wood
texture, it clashes with the colors in the trapdoor, and so
we add a wooden trapdoor-matching tile side texture as well.
This also improves the steel trapdoor side, but without a
texture change there since that was already a specially
drawn texture for that node.
We also increase the thickness of the trapdoor to 2px. Right
now the model is 0.4 large, but this causes the side textures
to look odd as there's a mismatch in pixel size. By scaling the
trapdoor side up to exactly 2px, the sides look natural.
Thanks to @kilbith for the suggestion.
There really is no reason to prevent rotation in trapdoors, I
expect this to be an oversight.
Trapdoors work perfectly well sideways, upside down and can
work like fences, gates and more. Most commonly, people will
want to put them in the top half of the node so they remain
flush with a floor.
In oversight, I added this recipe not verifying that it was already
taken.
We change this to a 2x2 iron bar recipe. The shape and amount are
reasonable (reduced to output 1 steel trapdoor), and I verified that
it wasn't in use.
Fixes #779
Adds a steel trapdoor. Textures were painted from scratch, and
inspired by the current Steel Door. Ownership on the trapdoor
works as expected, and so does the crafting recipe.
Mirror the setup of a door placed next to any door, not just next to
a door of the same type. This is particularly useful where there are
multiple door types that have the same appearance, but one wants the
doors of a pair to have different behaviour in some other respect.
When a trapdoor is mounted upside down, to make its top surface flush
with the floor above when closed, it is necessary to have some way to
climb through the trapdoor node when it's open. Making it climbable
like a ladder satisfies this need. It is somewhat realistic, as a real
trapdoor can have a ladder segment mounted on one face. When the trapdoor
is mounted in its default orientation, making the bottom surface flush
with the ceiling below when closed, the climbability when open is not
strictly necessary, but is still a convenience.
