This is a really interesting feature if we can make it happen. Sadly, Unity has a very limited capability dealing with sound. :( Well, this is expected as Unity is a game engine for game not for multimedia.
So far I got the pitch increased/slowed down based on the character speed and altered the volume based on the character position. Yes, this is not what we originally wanted. We want the audio is switched to LL audio as the character moved toward left and RR when the character moved toward right. However, as I check in the Unity documentation and script reference, there is no way to change the audio into LL/LR/RR. The only option I saw is to play it as mono sound. Well, I might as well find a new library for Unity like the iTween we used for the grinding or change the music playback mode on the left-right movement.
Btw, this Thursday we had more discussion about our game while having lunch together in Crimson View. We discussed what feature to be added into our game to engage player into the game. Craig pointed a really good question: what make it a playable game for more than 2 minutes? We want the player lose track of time as they experience music through our game. Nevertheless is our mechanics enough to engage them?
So far, we haven't come up with a really good idea. We still stick on the 'sliding' mechanics on the half pipe and the altered music playback based on the character movement. We had also stick on the static obstacle on the pipe where the player must avoid. These obstacle will either reduce the score, change the character speed or pushed toward the left/right.
Today we came up with some new ideas which, sadly, requires help from people from with experience in audio nor requires more time to accomplish. Those idea are
- when the game started, the music played is a music coming from only a musical instrument, as player hit/grab specific icon, additional music instrument will be added to the music.
- particle visual effect that changing based on the sound frequency like the sound wave in this YouTube: http://www.youtube.com/watch?v=s9GBf8y0lY0
- player started with white colour and as the music changed/player hit specific item that trigger musics, the colour will be added to the player - the colour of music
Well, for the prototype and with such a limited time, I believe this doesn't make sense to spend more time in doing the audio research. However, this can be added into the future plan of the game.
