Thank you!
and yes, it's possible. In the game option.rpy write: define config.has_voice = True
then in the game script you can code like this:
label start:
stop music fadeout 0.9
play music "music/music1.mp3" ###if you put the audio file in a different folder inside the game folder, write the path, like -> "music_folder_name/music1.mp3"
voice "voice1.mp3" ###same as above, if you have a different folder write the path -> "voice_folder_name/voice1.mp3"
m "Hello!"
p "(. . .)"
voice "voice2.mp3"
p "Who are you?"
stop music fadeout 1
return
also, if you download this other game you will have a wonderful example on how to do it: https://via01.itch.io/dont-open-your-eyes the scripts are uncrypted, so you can learn a lot on the process by examine the game files (and the game itself is very, very good! One of my favorites)
If you don't have an artist, you can ask to collaborate with someone by writing here for a free project: https://lemmasoft.renai.us/forums/viewforum.php?f=59
or if you want to do everything for yourself, you could always use pre-made, cc free assets (this link is just an example, but if you search "free assets renpy" you'll find a lot more): https://lemmasoft.renai.us/forums/viewtopic.php?f=52&t=56612&p=517667&hilit=free+assets#p517667
Again, I encourage you to read the cookbook because it's a life changer (XD) and also the people on the forum are very helpful and nice, they always answer all of your doubts on coding and stuff.
I appreciate the offer for a translation, it's always so awesome to have my game in other languages :D but right now I am abroad and I don't have the project on my pc, so I can't generate a translation script for you. If you want you can leave me your email so that I can contact you when I come back, or email me at schiva.games@gmail.com.
I thank you again for playing my game, and I will gladly play yours when it's done! Don't give up!
Have a wonderful day (and btw, your english is perfect )
