How can I create a new entity in DFHack? When I try
Code: [Select]
df.global.world.entities.all:insert(0, {new=true, type=1, id=df.global.entity_next_id})DF crashes when saving the world. When I add
Code: [Select]
entity_raw=another_entity.entity_rawto the new entity, it saves, but DF crashes when gets to the "Loading civilized populations" part of loading the world.

I think the request was some way to automatically hoover up on-load scripts that come with mods, so the player doesn't need to stitch them together manually.  This might simplify mod merging.

I'm picturing this as a standard bit in DFHack's onload script that runs every file in the raw/scripts folder that matches a specific filename pattern, maybe onload_*.lua|onload_*.rb.  It should be deterministically before or after the onload.init script at the root of raw.  Or put it in the raw/onload.init file, but I think the feature would be more user-proof if it functioned with the main file missing.

I'll add it to the list.

Is the goal to make it easier for homebrewed combinations of mods?

One problem is it looks like you aren't updating entity_next_id.

If I understand what you're doing then it probably can't be done. Certain things get read from raw files every time the game loads so it will almost definitely crash if it loads all the raw entities and then sees a reference to an entity that doesn't exist yet because it was created at runtime before it was saved. My guess is that the save code does some sort of check which catches this and crashes as a sanity check because it can't happen in vanilla DF.


Creating a new civilization/group should be possible but I think that's a different struct.

edit: Never mind. entity_raw is probably the one you can't create more of and making new entities is fine.

A starter pack's mod manager could in principle merge the scripts together, so yes this would be aimed at players throwing random and/or homebrewed mods together.  But it would also make the mod manager's job easier.

Now I do update df.global.entity_next_id, but it still has the same problem. I tried making a new population and adding its id to the new entity’s populations, but that didn’t work either.

Are there any scripts that successfully create entities that I can use as examples?

I'm trying to add announcements and combat log text to my scripts, I looked through the API and found
Code: [Select]
dfhack.gui.makeAnnouncement(type,flags,pos,text,color[,is_bright])and
Code: [Select]
dfhack.gui.addCombatReport(unit,slot,report_index)
But I am unsure what the type, flags, and slot should all be for a given announcement (also pos?). Anyone have any examples or a list of what the valid entries are?

EDIT: Also
Code: [Select]
dfhack.run_script('unit/body-change -unit 3399 -temperature fire -all')Is not working, it says
Code: [Select]
C:\Users\Miles\Desktop\My_DF2\hack\lua\dfhack.lua:410: Could not find script uni
t/body-change -unit 3399 -temperature fire -all
stack traceback:
        [C]: in function 'error'
        C:\Users\Miles\Desktop\My_DF2\hack\lua\dfhack.lua:410: in function 'run_
script'
        (interactive):1: in main chunk
        [C]: in function 'safecall'

rpreter'
        C:\Users\Miles\Desktop\My_DF2\hack\scripts/lua.lua:47: in main chunk
        (...tail calls...)
Note that putting that exact string into the command line works fine.

EDIT2: @Gorobay, I'm pretty sure its because you have a lot of fields that are left undefined if you just make a new one with type and id. Try instead
Code: [Select]
old = df.global.world.entities.all[0]
new = old:new()
new.id = entity_next_id
new.type = 1
blah
blah
blah

Roses, I found the Announcement command from Rubble (probably several versions old by now) that is much easier to use.

After all of the preparatory work is done building your string, it basically comes down to

dfhack.gui.showAnnouncement("Hello world!", _G["COLOR_RED"])

At the time I lifted the script, milo was manually echoing the announcement into the game's logfile, but the showAnnouncement method now seems to do that by itself.

Of course, this doesn't have as many ways to customize as the code you showed above.  For example, the snippet here has no location, so there's no way for the player to zoom to the location.

Edit: Here is the documentation for showAnnouncement and makeAnnouncement.  Probably just need to experiment with the flags or find a script somewhere that uses it.

Well, personally, I'm doing it so that others can do that more easily. I ended up going with a dfhack.run_command in my init.d/fortbent.lua file:

Code: [Select]
dfhack.run_command('script',SAVE_PATH..'/raw/fortbent_onload.init')

I wrote the following script as a test:
Code: [Select]
local old = df.global.world.entities.all[0]
local new = old:new()
new.id = df.global.entity_next_id
new.type = 1
df.global.world.entities.all:insert('#', new)
The game crashes when I exit the current mode and offload the world.

I have found reading the source code helpful for determining what the GUI functions do. The slot parameter of addCombatReport must be 0, 1, or 2 for combat, hunting, or sparring.

Is there any simple way of getting the products of a reaction that is linked to a LUA_HOOK function?  The example function includes output_items as a parameter, but as far as I can tell it is always empty

You might also have to change the value of save_file_id. Also I'm not sure if its going to freak out over having duplicate events and such.

reaction.products

Not that, that's the data from the reaction's object.  I want the actual items produced from the reaction.

I'm trying to make a function that runs after a particular reaction that produces a tool.  I want the function to run some script and then set the 'maker' field of the tool to a certain number based on that script.  How would I go about doing that?

Ah, I see what you mean. I misunderstood. As far as I know output_items should be what you want. If it isn't then I am of no help.
