I am afraid my scripting is based on m2tw. This is a really basic script command and I had expected it to be present in RTW as well.
If the event_counter condition doesn't work then the 'regular' counter will, notice the additional declaration of the counter and the altered SeasonCount lines:
declare_counter SeasonCount
console_command date -270
console_command season summer
advance_advice_thread Turn_0_Year_270_BC_Season_1_Thread
set_counter SeasonCount 1 ; <--- the counter for reference in trigger
while I_TurnNumber = 0
suspend_unscripted_advice true
end_while
console_command date -270
console_command season summer
advance_advice_thread Turn_1_Year_270_BC_Season_2_Thread
set_counter SeasonCount 2
while I_TurnNumber = 1
suspend_unscripted_advice true
end_while
console_command date -270
console_command season summer
advance_advice_thread Turn_2_Year_270_BC_Season_3_Thread
set_counter SeasonCount 3
while I_TurnNumber = 2
suspend_unscripted_advice true
end_while
console_command date -270
console_command season summer
advance_advice_thread Turn_3_Year_270_BC_Season_4_Thread
set_counter SeasonCount 4
while I_TurnNumber = 3
suspend_unscripted_advice true
end_while
console_command date -270
console_command season winter
advance_advice_thread Turn_4_Year_270_BC_Season_5_Thread
set_counter SeasonCount 5
while I_TurnNumber = 4
suspend_unscripted_advice true
end_while
console_command date -270
console_command season winter
advance_advice_thread Turn_5_Year_270_BC_Season_6_Thread
set_counter SeasonCount 6
while I_TurnNumber = 5
suspend_unscripted_advice true
end_while
console_command date -269
console_command season winter
advance_advice_thread Turn_6_Year_269_BC_Season_1_Thread
set_counter SeasonCount 1
while I_TurnNumber = 6
suspend_unscripted_advice true
end_while
The trigger will then change slightly as well, again check the SeasonCount line:
Trigger summer_calibration_turn_1
WhenToTest CharacterTurnStart
Condition I_CompareCounter SeasonCount = 1
and Trait Season < 2
Affects Season 1 Chance 100
Big note: I found
the docudemons for BI, they contain the scripting events, commands and conditions as well as console commands. As ALX got released after BI I am assuming that they will work for us.
