This was implemented because placing floors near water would mess up the terrain.
but if you go into your factorio folder -> Factorio\data\base\prototypes\item and open demo-item.lua.
in here (in version 12.33) you'll see right at the top:
Code: Select all
{
type = "item",
name = "stone-brick",
icon = "__base__/graphics/icons/stone-brick.png",
flags = {"goes-to-main-inventory"},
subgroup = "terrain",
order = "a[stone-brick]",
stack_size = 100,
place_as_tile =
{
result = "stone-path",
condition_size = 4,
condition = { "water-tile" }
}
},
You want to set condition_size to 2 if you want to build right up to the water, to 1 if you want to include the coast tiles and 0 if you want to build on the water.
Now open item.lua and right at the bottom you'll see:
Code: Select all
{
type = "item",
name = "concrete",
icon = "__base__/graphics/icons/concrete.png",
flags = {"goes-to-main-inventory"},
subgroup = "terrain",
order = "b[concrete]",
stack_size = 100,
place_as_tile =
{
result = "concrete",
condition_size = 4,
condition = { "water-tile" }
}
}
Again edit the condition_size but this time for concrete.
