I learnt that the Wwise audiokinetic system allow program to call “Event” in game, such as “Play_Flare” (or maybe there is a “Stop_Flare” ?), “Pause_all”, “Resume_all”…
If it can be used in custom campaigns, that would be amazing!
So I tried to make a “BGM_549CAA69.wem” with two Events named: “Play_BGM_JinZhang” and “Stop_BGM_JinZhang”, and their target is rightly the file “BGM_JinZhang.wav” (by Wwise 2019.1.5, Vorbis, Quality=4, SR=44100, Channels=2.0-stereo, language=SFX).
After that I put this .wem into my local mod folder (C:\Users\acer\Games\Age of Empires 2 DE\76561199002600352\mods\local\LianYouGuo\resources_common\drs\sounds), and restart the AoE2DE.exe.
Then I create a function in edtior: “Play Sound” with [Sound (Event) Name] of “Play_BGM_JinZhang”. When testing, NOT-THING played;
Then I changed the [Sound (Event) Name] to “BGM_549CAA69”, and it played normally. (←This method is from StepS’s guide)
So… Are there any points I missed or did wrong? Or is it indeed imposible for custom Events to work in scenario during current edition?
