This mod makes soil and soil-like nodes capable of holding temporary "footprint" impressions, and if they're walked on repeatedly turning into hard-packed trails.
It also allows players to flatten plants by walking on them.
It includes definitions for footprint-capable nodes in the "default" mod, and has an API for allowing nodes in other mods to use the same system.
New trampled nodes can be registered with this API:
footprints.register_trample_node(trampleable_node_name, trample_def)
trample_def:
{
trampled_node_name = , -- If this is not defined it defaults to the
-- trampleable node name with "_trampled" appended.
trampled_node_def_override = {}, -- If trampled_node_name doesn't exist a new
-- node will be registered based on the definition of
-- trampleable_node_name. Any properties in this table
-- will be used to override properties. Ignored if
-- trampled_node_name is a node that already exists.
probability = 1, -- chance that stepping on this node will cause it to turn
-- into the trampled version (range is 0.0 to 1.0)
trample_count = 1, -- The number of times this node needs to be stepped on
-- (and pass the probability check) to transition to
-- the trampled state
randomize_trampled_param2 = nil, -- if true, sets param2 of trampled node to math.random(0,3)
-- This is used for trampled wheat, for example, to randomize the thatch's
-- direction.
erodes = true, -- sets the trampled node to erode back into the non-trampled
-- version over time, if erosion is enabled in this mod's settings.
-- Ignored if trampled_node_name is a node that already
-- exists, since that may already have an erosion target established.
add_footprint_overlay = true, -- Applies the footprint texture over the +Y tile of the
-- trampleable node. ignored if trampled_node_name is a node that already exists
footprint_overlay_texture = "footprints_footprint.png",
footprint_opacity = 64, -- defaults to 64 (0 is transparent, 255 is fully opaque)
hard_pack_node_name = nil, -- If the trampled node is walked on again this is the
-- node that it can get further packed down into. ignored if
-- trampled_node_name is a node that already exists, since
-- it's expected this has already been established
hard_pack_probability = 0.9, -- The probability that walking on a trampled node
-- will turn it into the hard-packed node (0.0 to 1.0).
-- ignored if trampled_node_name is a node that already exists
hard_pack_count = 10, -- The number of times the trampled node needs to be stepped on
-- (and pass the probability check) to turn to the hard packed state
}
Note that all of the parameters in trample_def have default values, so if you want you can just pass in nil and the footprints mod will create a footstep-marked version of the node and set it all up for you with no further information needed. "footprints.register_trample_node("modname:dirt")" will work.
If you've defined a hard_pack_node and want to have it able to erode back to base soil, you can use this callback to manually add it to the erosion system:
footprints.register_erosion(starting_node_name, restored_node_name)
Note that the source_node should be in group footprints_erodes or an error will be thrown.
If you've got the farming mod installed you can allow hardpack nodes to be restored back to soil using a hoe with the following function:
footprints.register_hoe_converts(starting_node_name, restored_node_name)
