How Do Events Work

Hey Rappelz Community

I am trying to figure out how Events work and not entirely sure what the best way is to enable them.

I suspect it just a matter of adding the event items to the drop table for the monsters and then setting up an appropriate NPC to do the exchange (if applicable).

Though if I look at the database I can see a number of tables related to Events:

• Arcadia.dbo.EventAreaResource
• Arcadia.dbo.NPCEventPeriodResource
• Telcaster.dbo.EventAreaEnterCount
• Telcaster.dbo.EventDungeonDropRate
• Telcaster.dbo.EventGiftItemAcquiredUser
• Telcaster.dbo.EventInfo
• Telcaster.dbo.EventItemDropInfo
• Telcaster.dbo.EventItemSupplyInfo
• Telcaster.dbo.EventLogin

So I am not sure if there is a more specific way to enable or add events?

I know there are tools out there but I more want to understand how events work.

Anyone care to shed some light, please?

you just code event in lua, no need to use any of those tables tbh

Thanks yosiemelo, I understand that I can just use the Lua to programmatically add/remove event drops/NPC's.

Though I am interested in understanding how these tables were used for events. For instance lua is a single threaded language so how would I write a script to keep running in the background to check if the event should have ended already to remove event items from the drop table without binding up the thread. I am not sure if this is possible. Of course since I am not running a production service, I will just do the check during server init and check against a hard coded dates and if so it will either enable an event or disable it.

Of course I would prefer to do this via the database (if it possible) that way things can remain tidy. Again nothing more than a curiosity to learn more at this point in time.

Sure — you can do that. In fact most events are time-based and they ARE checked dynamically, just not in the “run a Lua background thread forever” way.

The tables you posted are mainly there to store data that you already add/configure from Lua anyway. They don’t really “create” the event logic.

For example:

Telcaster.dbo.EventItemDropInfo
Telcaster.dbo.EventItemSupplyInfo

Those are basically persistence tables. They exist so the server can remember that an event was enabled + what drops it had, so if the server crashes or restarts it can restore the state instead of losing it.

And honestly, personally I don’t think making events in the database makes any sense here. There are too many limitations and it works in a very clunky way. It’s really not worth going deep into that topic when Lua events are cleaner and more flexible.

If you want, I can explain how I write events in Lua the proper/clean/optimal way on Discord. Just come with any example event idea and I’ll give you pseudocode that shows the whole mechanism and the intended structure. You’ll probably also pick up a few tricks I use.
