Add graphics support for building-hacks #4380

warmist · 2024-03-17T15:40:43Z

This intends to reenable building-hacks namely machine workshops with animations.

Things to consider:

general "is this useful to anyone else"?
doc update not done yet
(?) redo the api as it sucks. Lua part simplifies the api a little...
how do you get tile ids (ala raws) in lua (i.e. how to make the api work?)
getImpassableOccupancy fix still needed?
canBeRoomSubset thingy for interesting room manipulations, but not sure about usecases
not very kosher use of random reference for machine power tracking...
updateAction - probably could be removed and replaced with a lua on tick update or sth...

Edit: less theoretical musings, more "works for now" logic.

~~make stuff automagically work from raws~~ moved to a lua only module (different pull req later)

plugins/building-hacks.cpp

myk002 · 2024-03-17T16:37:21Z

Can the plugin automatically enable itself if it detects that it is used in the raws, the same way that add-spatter does? That way the player won't have to manually enable it to get things working.

general "is this useful to anyone else"?

as useful as add-spatter, which I'm also happy to include

how do you get tile ids (ala raws) in lua (i.e. how to make the api work?)

it depends which tile ids you're getting. will it be a vanilla texpos or one added by DFHack?

Can the plugin automatically enable itself if it detects that it is used in the raws, the same way that add-spatter does? That way the player won't have to manually enable it to get things working.

It depends: for basic functionality it should be possible. It can be split in a few different things that this plugin does:

Impassable fix - this might be already in df? Need to check. Basically fixes that workshop impassible tiles would allow water through.
Generate power - unlikely that it's useful. Usually need some sort of "when fuel exists/etc" and probably used from lua
Consume power - probably useful straight from raws, but it needs an argument (i.e. how much power do you need)
animation - have no idea how to do it from raws
canBeRoomSubset - ugh...

how do you get tile ids (ala raws) in lua (i.e. how to make the api work?)

it depends which tile ids you're getting. will it be a vanilla texpos or one added by DFHack?

It's vanilla texpos but e.g. you do:

graphics_dragon_engine

[OBJECT:GRAPHICS]

[TILE_GRAPHICS:DRAGON_ENGINE_TILES:0:0:WORKSHOP_CUSTOM:DRAGON_ENGINE_N:3:0:0]
[TILE_GRAPHICS:DRAGON_ENGINE_TILES:0:1:WORKSHOP_CUSTOM:DRAGON_ENGINE_N:3:0:1]
[TILE_GRAPHICS:DRAGON_ENGINE_TILES:0:2:WORKSHOP_CUSTOM:DRAGON_ENGINE_N:3:0:2]
[TILE_GRAPHICS:DRAGON_ENGINE_TILES:0:3:WORKSHOP_CUSTOM:DRAGON_ENGINE_N:3:0:3]
[TILE_GRAPHICS:DRAGON_ENGINE_TILES:0:4:WORKSHOP_CUSTOM:DRAGON_ENGINE_N:3:0:4]

and then you need yet another tile for animated part. Or you need to do something similar in the lua part.

myk002 · 2024-03-17T17:47:57Z

add_spatter looks for SPATTER_ADD_ in any reaction. Could this look for a similar token prefix across the loaded building raws?

for looking up the graphics tile from a loaded page, I think you'd use dfhack.screen.findGraphicsTile(pagename,x,y)
that's slow, though, so you'd probably want to cache it and wipe your cache on a map load event.

warmist · 2024-03-18T19:47:40Z

So api is still terrible but less so. The rest of stuff doesn't matter that much, so i think i'll add (or at least try to add) automagical way of this loading stuff from raws and auto-enabling itself. In perfect case having a line [DFHACK_MACHINE:25] would make any workshop to have power drain of 25 to work. This ofc is not perfect (e.g. how about interface, what if you want to provide power, etc...) but it would lower cost of entry for a lot of modders.

Another issue that plagues this module for many years: buildings need to built in specific order to connect to machines...

plugins/building-hacks.cpp

plugins/lua/building-hacks.lua

warmist · 2024-03-24T14:45:12Z

This is now relatively done. Needs more testing.

The "make it work from raws" is a separate project and probably lua only.

warmist · 2024-03-29T09:23:52Z

~~Ok, this is as done as I currently can make it be.~~
~~Spoke too soon. Some issue remains with 0 or 1 based building tile indexing?~~
Ok NOW it's done 👯

myk002

reviewed docs and lifecycle code; will review business logic once some questions are answered.

could you add a changelog entry for the update?
could you update docs/plugins/building-hacks.rst and replace the "unavailable" tag with "fort gameplay buildings". Maybe "adventure fort gameplay buildings" if it's intended to work in adventure mode too.
we need a full example of the RAWs and scripts for how to make this all work. It could be added to the modding guide as a case study. You could link to the modding guide from both the Lua API docs and buiding-hacks.rst.

is this for overriding the default gear graphics? If so, that should be communicated.

+------
+
+This module exports two events. However only one is documented here and is intended to be used directly. To use
+``onUpdateAction`` instead call ``setOnUpdate`` function.


why does onUpdateAction exist as a Lua event, then?

The plugin lua part still uses that event (i.e. setOnUpdate function)

I'm not convinced this is sufficient reasoning. Why do you need a lua event to communicate with your own Lua layer? Why can't you call the Lua functions directly?

myk002

needs changelog entry

I added some code examples in my comments to show what my understanding is of how these functions are to be used. If the examples are wrong, then I didn't understand something important.

Would it be a good idea to always allow the building to be ownable? If in zone, and zone owned, then building owned?

world.

Dynamically sets current power production and consumption for a specific workshop

(which must be of a type registered with building-hacks).

I note that the order of consumed and produced power is in the opposite order compared to setPower. They should match.
