I have been trying to create a series of events that can count odd and even days. After using some mathematical logic, I came up with a series of three events that can turn a flag on and off every other day to signal even and odd without having to have the current day as a condition. This would be useful if you want something on your map to happen every other day. FOR example Advanced Wars Laser cannons that charge on odd turns and shoot on even ones. Prior the only way to do it is if you signify which days 2, 4, 6, 8, 10, etc. for an event to happen. The events have to be sequenced in this specific order in your trigger page, since triggers are executed top to bottom. This prevents us from having 2 events that say (if flag off turn flag on), and (if flag on turn flag off.) The flag will always resort to which ever event is listed last. Here are the three events. You also need two flags. Flags: Even default true Turn default true Trigger Name: 1 When: Repeat Players: Player 1 Conditions: -At the end of the turn. -Is it Player 1's turn? -Is map flag Even true? -Is map flag Turn true? Actions: Set Map Flag Even to false. Set Map Flag Turn to false. Trigger Name: 2 When: Repeat Players: Player 1 Conditions: -At the end of the turn. -Is it Player 1's turn? -Is map flag Even false? -Is map flag Turn true? Actions: Set Map Flag Even to true. Trigger Name: 3 When: Repeat Players: Player 1 Conditions: -At the end of the turn. -Is it Player 1's turn? -Is map flag Even false? Actions: Set Map Flag Turn to true. After these three events, you can create any event with the Is Map Flag Even true/false as a condition. On even days that event can happen and on odd it can't. (And vice versa) (All other events will not matter where they fall in the sequence of triggers as long as these 3 are one after the other in order.) Also, you can use this to trigger things every other time something happens. Unit lost, Unit end turn, player end turn, etc... You just have to figure out what conditions you want to change. If you want to do the math to figure out why it works, I suggest you do! My next challenge will be to create events that happen every 3 or 4 or n days at a time.
