Loggy's Random Events reverse engineering notes

Generating Random Events

• Events are considered on a nation-by-nation basis, for every nation that is in the game.
• Each nation in the game gets a total of four checks.
  • Check 1 has a base event rate of 15.
  • Check 2 has a base event rate of (owned provinces*3)+2.
  • Check 3 has a base event rate of (owned provinces*2)+2.
  • Check 4 has a base event rate of (owned provinces) + 2.
• The event rate is then calculated as:
  • base event rate + (turmoil's modifier) + (luck's modifier).
  • The scales are considered in the nation's cap only for this check.
• If the event rate is less than 3, it is set to 3.
• Then min(calculated event rate and (current turn number * 5)) is used as the final event rate.
  • The event rate is divided by 2 if random events are rare.
  • If this is check 4, divide the event rate by 2. Both these divisions can happen after each other.
• If (random number 0-99) < calculated event rate, generate an event.
• The game then determines:
  • If the event is good or bad.
  • A random province where the event occurs.
• If the event is bad, the game checks every unit on the map to see if any are in the targeted province and have a fortune teller ability
  • If yes, the game then rolls for this ability.
• The event is then triggered.
• If this was check 1-3, the game rolls again, checking the next consecutive number.
• If this was check 4, random event rolls are completed.

Determining Good or Bad Events

• Whether an event is good or bad depends on the following calculation:
  • Luck scale in a province * the global luck "event is good" value.
    • Note: If the province is not under friendly dominion, any positive luck scales are ignored and 0 is used instead.
  • If (random number 0-99) < 50 + the "event is good" %, the event is good.
    • IE: neutral scales is 50/50, misfortune 3 is 80% bad and 20% good
