Set tiles

[vtx]

It's said to use this function as a batch. How the right way to do it ?

Code: Select all

set_tiles({"grass",{1,1}},{"grass",{2,2}},{"grass",{3,3}})

[prg]

LuaSurface::set_tiles

Code: Select all

set_tiles{{name="grass",position={1,1}},{name="grass",position={2,2}},{name="grass",position={3,3}}}

I check the lua api I was thinking it's working same as position.

Both are valid : {1,1} or {x = 1, y = 1}

Explicit specification are required and no shorthand allowed for that function.

Thanks for clarification.

I think it can be short, but with wrong position in table.

Emmm...
using them in cycle will not work?

Code: Select all

for x = 1,10 do
    for y = 1,10 do
        set_tiles({"grass",{x,y}})
    end
end

[prg]

end

From LuaSurface::set_tiles:

Note: It is recommended to call this method once for all the tiles you want to change rather than calling it individually for every tile. As the tile correction is used after every step, calling it one by one could cause the tile correction logic to redo some of the changes, and it is also much performance heavy.

Code: Select all

local tiles = {}
for x = 1,10 do
    for y = 1,10 do
      table.insert(tiles, {"grass",{x,y}}
    end
end
set_tiles(tiles)

[prg]

Code: Select all

local tiles = {}
for x = 1,10 do
    for y = 1,10 do
      table.insert(tiles, {"grass",{x,y}}
    end
end
set_tiles(tiles)

That still won't work without "name" and "position" as keys.

Are you sure about that ?
There are 2 different type of function in lua api.

Code: Select all

can_place_entity{name=…, position=…, direction=…, force=…}

"=..." seem to be where you MUST use explicit specification

Code: Select all

find_entity(entity, position)

without "=..." seem to accept shorthand.

without "=..." seem to accept shorthand.

If it have right position.

[prg]

Are you sure about that ?

Code: Select all

/c game.player.surface.set_tiles{{name="grass", position={1,1}}}

Works.

Code: Select all

/c game.player.surface.set_tiles{{"grass", {1,1}}}

"Expected field name in tile set item."

Code: Select all

can_place_entity{name=…, position=…, direction=…, force=…}

is just short for

Code: Select all

can_place_entity({name=…, position=…, direction=…, force=…})

passing the table as the first argument. That's how "named" arguments are done in Lua. Now set_tiles expects a table of tables containing tile descriptions as its first argument. Those tables with tile descriptions apparently are required to contain "name" and "position" as keys.
