invisible floor with movement speed modifier?

[ownlyme]

when i replace all the graphics with invisible ones, something like a black hole is created, it uses whatever has been displayed there before.
I even tried it with the vanilla prototype by making all the concrete graphics transparent, but didn't help.

background:
i'm working on a powered floor mod, the floor is the size of 2x2 tiles, they have 8 edges so a fraction of the texture is transparent
if someone can help me decrease the amount of entities i need per tile, that would be helpful too..
i need:
- power pole (power an area of 4x4)
- turbine (gets steam via script)
- lamp (glow at night)
- movement speed modifier
- displayed floor tile (none of the above have a render_layer property -_-)

thank you for reading.

Tiles do not stack and are are always rendered as the lowest layer. If you want to make something that looks like a tile but still be able to see the "ground" beneath it, then you have to use something that's not a tile. Tiles also don't allow layering so that's not an option either.

Also i don't get what the steam is for, are they not connected to the electricity network? (As far as i know you can hide power wires per entity in the current version if they look ugly.)

oh i really can hide power wires? i thought that was impossible...
thanks, gonna try that out.
the problem with the tiles is that i need some kind of movement speed modifier, but basically you should still be able to see what ever is below it

Not gonna happen. There can never be anything "below" a tile.

[ownlyme]

i saw a movement speed modifier on some trivial smoke prototypes, but it probably won't affect vehicles.
does that even work? i tried spawning one of them and either they are invisible or dont work..

How would you do that? i just found a hack that involves spawning them on another surface

Added optional Electric pole prototype "draw_copper_wires" and "draw_circuit_wires".

okay cool,
about my hidden concrete question:
i found this:
find_tiles_filtered{…, has_hidden_tile=…
what's this hidden tile? would that be the solution to my problem?

btw: if a prototype has some unusual properties, why not put them into the factorio-data-master on github?

Wild speculation: The engine does store what tile was "originally" there if you build concrete etc, so that it can place it back when you remove the concrete. That might be a "hidden tile". But as you can see the api doesn't even tell you the name of that tile, it only tells wheather it exists. And regardless, this has no effect on rendering. There is no "solution" to your problem unless you can find something else to give the movement bonus (i remember seeing an odd mod that had movement bonus on...something, but i can't remember what it was). Or you could script the movement bonus.

Got a link?

but i dunno why you would use that now that there is a wire hiding property

i assume by scripting you mean comparing the player position with all the positions of my tiles?
unless i can merge those zones that would be quite heavy,
i think using a find-entities-in-area check every 3 ticks would be even heavier...

That post is from 2016. Cross-surface connecting has been removed quite some time ago.

Yes. Something using on_player_changed_position and a truth map of all tile positions. I.e.

Code: Select all

local pos = player.position
if tiles[pos.x] and tiles[pos.x][pos.y] then
  --dostuff
  end

Is that a nice solution? No. It's just "a" solution. And if you do it wrong every other mod author accessing player speed will be waiting with a pitchfork at your doorstep :p.

Imho: Just give up on the idea that you can see "below" the floor. Just pretend it's all concrete below. And voila you only need one texture and it works fine...

SOLUTION:
i just copied all the vanilla tiles and replace them upon building

but i had to copy them manually because iterating through data.raw["tile"] caused suuuuper weird error messages

Code: Select all

local extend = {}
for name, tile in pairs(data.raw["tile"]) do
if tile.map_color and name ~="out-of-map" then --tried different filters, these were just the last ones i tried, so yes it also happens with non-water tiles
	local newtile = {}
	newtile.name = "power-"..name
	newtile.type = "tile"
	local temptile = table.deepcopy(tile) --this weird approach was also just my last attempt trying to sort the table manually..
	for key, entry in pairs(temptile) do
		if key~="name" and key ~="type"then
			newtile[key] = entry
		end
	end
	newtile.autoplace = nil
	newtile.walking_speed_modifier = 1.8
	newtile.vehicle_friction_modifier =0.65
	table.insert(extend,newtile)
	break
end
end
data:extend({extend})
