Bind on BPFunction on BPW Boom Box Player widget blueprint and in its PreConstruct event i subscribed to OnVolumeChanged event. It works and when i move volume slider i receive float values from 0 to 1.SetRTPC node that accepts some Ak object. Is Ak a play event? But i don't manage play events directly, boombox does, i only placed references to my play events in the tape blueprint. And i don't see Set RTPCValue node, i have Set Global RTPC Value and Set Actor RTPC Value. I tried using Set Global RTPC Value (first attached image), but that didn't work.
