MTTH is the possibility to happen. If an event has
months = 1 as MTTH, the event will fire once pro month. In my experience, events with MTTH under months = 1000 trigger very often, since the AI checks the MTTH every day in game.
0.3 or 2 means 30% or 200%. In the above case, the event will fire once in 450 months (1500x0.3) when the character has no trait (
Not = { x } means the condition x is not fullfied). Other than these two points, you have correctly understood. The modding is not SO difficult, isn't it?
Close, but not quite. MTTH means there's a 50% chance that the event will happen after the time stated, not a 100% chance - there's never a 100% chance an event will fire.
So, if you have a province event with a MTTH of 500, then after 500 months there's a 50% chance it will have fired. After 1000 months, there is a 75% chance it will have fired. After 1500 months, there's an 87.5% chance... etc etc. It checks every province in the game for whether the event fires, so in this case you have what, 250ish provinces with a 50% chance of having fired by month 500 - so in practice, it'll probably fire somewhere on day 15 or so.
The event you're refering to is a character event, and there's like 15 characters per court, and about 100 courts in the game at any given time. So the game is making 1500 checks per day, meaning that even with only a 1% chance or so on day 1 15 characters are likely to get it.
There's also letter events, which refer to letters - which are comparitively rare, so a MTTH measured in 10s is appropriate for them. I haven't seen any sign of country events in Sengoku.
So, just to recap:
Letter events require another event to set them up, and should probably have MTTHs in multiples of 10 - like 50 or so.
Province events are usually available to all provinces, so should have MTTHs in multiples of 100 or greater; probably 1000-2000ish. Unless they have very stringent requirements, like 'must have event modifier X AND a level 8 village or greater', in which case the MTTH can be relatively low, like 200 or less.
Character events are going to fire all over the shop, and should have MTTHs measured in 1000s at least.
No event is ever certain to happen, as it will only increase by 50% of the previous increase each time. There's never a 100% chance.
I generally mod V2, myself, but the coding is pretty similar and I've been working with it for a long time now, so feel free to PM me if you have any queries on stuff - I have probably encountered the problem myself somewhere along the line and know either a fix or a workaround. KPJ can probably vouch for that
