How do you use the Activate Custom Random Event Group in the Randomizer Object? Let's say you had groups called A, B, C, and D. What would you put in the first field? And what is the Total Percent number (what does 0 do and what does 100 do)?
In the first field I've tried numerous things, like: "A, B, C, D" and "A","B","C","D"
PS: Within each of those Event Groups is a single Event: At the start of frame, play a sample. That's the only way I could think of to have random music. Is there a better way (iOS and, eventually, Android compatible)?
