Hi everybody,

I'm just thinking about configuration of a prefilled warehouse for the empire tribe. Meaning: if it's finished builded, it instantly has a number of stones/wood/workers/etc.

How can this be solved? Are there any existing parameters for the lua files where this idea could be added? Or is there another way to solve this topic as an non-developer?

Thanks for developing this really nice game - much appreciate this so far... face-smile.png

Hi WidelandMonkey,
welcome to our forums.
you might have a look at our scripting references. (Here)[https://www.widelands.org/documentation/autogen_map_object_programs/] you find how to call a script with an immovable Program. In this script you could use the lua function set_wares().
Not tested if this works, but it might be worth a try.

Does exists something like a trigger/event "finished building warehouse"? In case, this could be an opportunity to start the script "fill-up warehouse"... Didn't find anything like this...

Unfortunately no. You can only do that by starting a coroutine that regularly checks the player's warehouses.

Re @hessenfarmer's post: I don't think immovable programs are run for warehouses.

Seems to be more complex than expected - as nearly always in development... face-grin.png Maybe I have to learn more about coding, especially with lua & co...

If i am not mistaken a new warehouse sends a message to the inbox of a player. You may can check the players inbox for a corresponding message. The message contains the field (x/y coordinate) and with this information you can get access to the warehouse and use set_wares(), like hessenfarmer said.

In the future this might be easier if signals will be implemented.
