Follow-up Comment #2, bug #23721 (project wesnoth):
While this sounds like a useful feature i currently dont know how to implement
this, the problem is, that crrently the code which adds those events doesn't
know whether we currently have the first scenario.
> Currently coders can only "create such event" via [filter_condition], wich
has as drawback that event is still loaded but not executed in all scenarios.
You can also remove such events using event ids, you can also have a marco
like this (untested) which makes it easier:
#define FIRST_SCENARIO_EVENT ID CODE
[event]
name = preload
first_time_only = yes
[if]
[filter_condition]
[variable]
name = is_not_first_scenario
equals = yes
[/variable]
[/filter_condition]
[then]
[remove_event]
id = {ID}
[/remove_event]
[/then]
[/if]
[/event]
[event]
name = prestart
first_time_only = yes
id = set_is_first_scenario
[set_variable]
name = is_not_first_scenario
value = yes
[/set_variable]
[/event]
[event]
id = {ID}
{CODE}
[/event]
#enddef
