Node boxes
|
||||
-----------
|
||||
Node selection boxes are defined using "node boxes"
|
||||
|
||||
The "nodebox" node drawtype allows defining visual of nodes consisting of
|
||||
arbitrary number of boxes. It allows defining stuff like stairs. Only the
|
||||
"fixed" box type is supported for these.
|
||||
^ Please note that this is still experimental, and may be incompatibly
|
||||
changed in the future.
|
||||
|
||||
A nodebox is defined as any of:
|
||||
{
|
||||
-- A normal cube; the default in most things
|
||||
type = "regular"
|
||||
}
|
||||
{
|
||||
-- A fixed box (facedir param2 is used, if applicable)
|
||||
type = "fixed",
|
||||
fixed = box OR {box1, box2, ...}
|
||||
}
|
||||
{
|
||||
-- A box like the selection box for torches
|
||||
-- (wallmounted param2 is used, if applicable)
|
||||
type = "wallmounted",
|
||||
wall_top = box,
|
||||
wall_bottom = box,
|
||||
wall_side = box
|
||||
}
|
||||
|
||||
A box is defined as:
|
||||
{x1, y1, z1, x2, y2, z2}
|
||||
A box of a regular node would look like:
|
||||
{-0.5, -0.5, -0.5, 0.5, 0.5, 0.5},
