[unsolvable] Access event content

[ZombieKnight]

Hi,
How to access event content via Lua?

[Celtic_Minstrel]

There's no official way. If wesnoth.scenario.__cfg exists, you might be able to get them from there.

Double checked I can't do it.

It probably does not catch everything, but you can overwrite wesnoth.wml_actions.event to save what is given to it.

True... but how to notice when it's fired?

[Celtic_Minstrel]

Maybe queue a second event with the exact same conditions? Or insert extra code at the start of the event that does whatever you need it to do?

I'm pretty sure I don't understand what you are asking, but if you mean you want to access (read) events you've written in WML from lua, could the answer be as simple as just writing them in lua in the first place?

Or some combination of wesnoth.game_events.on_event and wesnoth.current.event_context ?

[ZombieKnight]

... hmm not sure
Can I use wesnoth.game_events.on_event and wesnoth.current.event_context to re-create all those events (right after I erase them)?

I don't know, I've never used them. But for those I was thinking about your question about 'how to notice when it's fired'.

If you want to erase them (the events) and recreate them, you could:

1) Since you want to do this from lua, just write them in lua in the first place, save them as variables, and delete (fire remove_event) and re-create them as you please.

2) Just have all of your events check a variable $disable_all_events (or something) so you don't delete them, just disable them.

3) If you want to write the events in WML, use Ravana's neat trick to keep them in a separate file so you can (re-)load them from lua. I think it's just a tiny bit more complicated than I have described, since you'd need to load an action which creates them (you want to create them, not execute them), but I doubt that's too tricky.

Now, if you don't know the id's (I assume you'll have to have id's on all your events) ahead of time for some reason, you'd have to be able to get a list of them dynamically. No idea there.

Hmm
... I see
I wanted to save and load anything at any time.
