Randomizing voice audio files

[Vielfalt]

Hi,

In my game, a character greets the player when he passes by, via bark dialogue, which works well. I'd like to randomly shuffle the voice audio files, to prevent the player from hearing the same intonation all the time. So I added this Sequence, but it always plays the first file:

Code: Select all

RandomizeNextEntry(true);
AudioWait(Voice/Receptionist - Good day sir 1);
AudioWait(Voice/Receptionist - Good day sir 2)

I probably misunderstood how RandomizeNextEntry works...?

Furthermore, I'd like there to be a minimum interval between this specific bark, so that the player isn't greeted more often than once per minute for example. What's the simplest way to implement this? Can it be done with a variable (lastBarkTime) and Lua script in Dialogue System, or do I need to write C# scripts?

Hi,

If you wanted to randomly choose between 2 voice files, you could use a sequencer command like this:

Code: Select all

AudioWait(Voice/Receptionist - Good day sir [lua(RandomElement("1|2"))])

It uses the RandomElement() Lua function to randomly choose between "1" and "2".

However, if you have the added restriction of not playing a voice file if less than a minute has passed, it's probably best to write a custom sequencer command. Please see part 6 of Cutscene Sequence Tutorials.

Thanks a lot, RandomElement() works like a charm here!

Regarding the minimum time interval between barks, I managed to implement it with Lua in the Dialogue System Trigger:

• Lua condition:

  Code: Select all

  os.clock() > Variable["PrevGreetingTime"] + 60

• Actions / Run Lua code:

  Code: Select all

  Variable["PrevGreetingTime"] = os.clock()

Coming from C++ and Swift, Lua is new to me, but I'm starting to like it

Glad to help! Nice solution for the bark timer.
