If a player wants to make a path when there is no dirt with grass on the
ground it means they need to either have silk touch to collect dirt with
grass or place dirt beside dirt with grass and wait for the grass cover
to spread before they can create the new paths …
Since the former is not possible early in the game and the latter is not
easy, this patch imitates Minecraft 1.17 behaviour; the following nodes
can now be turned into path nodes by right-clicking them with a shovel:
• Dirt (mcl_core:dirt)
• Coarse Dirt (mcl_core:coarse_dirt)
• Dirt with Grass (mcl_core:dirt_with_grass)
• Mycelium (mcl_core:mycelium)
• Podzol (mcl_core:podzol)
A group “path_creation_possible” has been added to mark nodes that can
be turned into a dirt path with a shovel. One obvious objection to that
addition might be that the “dirt” group already exists. Even though all
existing nodes that can be turned into a dirt path do indeed belong to
the “dirt” group, it is not a good idea: Changing what “dirt” means to
“any node that can be turned into a dirt path” would make it harder to
maintain the code.
The code for shearing a pumpkin used minetest.swap_node() to replace a
faceless pumpkin with a carved pumpkin. This did not trigger the node
callbacks of the carved pumpkin, which meant that shearing a pumpkin
would not check for the snow golem or iron golem spawn conditions.
This patch replaces minetest.swap_node() in the code for shearing a
pumpkin with minetest.set_node(), which does trigger the callbacks;
therefore snow and iron golems can now spawn as a pumpkin is carved.
Group levels are now specified as a list of names when registering a
digging group. Digging groups which do not have specified levels will
support tools having two levels, 0 and 1 where 0 means the tool can dig
but not harvest the node and 1 means it can also harvest the node. If
more levels are required one has to specifiy them when registering the
digging group.
Added the API function mcl_autogroup.get_wear which is used to get the
tool wear for digging a node of a group. This is used by mcl_tools to
compute the wear of shovels and shears when rightclicking to create
grass paths and carve pumpkins.
