Detecting Sound Radius

TouchTiltGames

Hey guys, I am looking for a tutorial or video tutorial or..template on sound radius.
As you get closer to an actor the sound gets louder, as you move farther away it gets quieter.
Cheers!

Create an attribute called game.soundDistance (real). Create two integer attributes (soundSourceX and soundsourceY). Constrain these to the x and y of the source of the sound. In the moving character constrain game.SoundDistance to magnitude(self.positionX-game.soundsourceX, self.positionY-game.soundsourceY).

Now you can put game.SoundDistance in the expression editor of the play sound behavior. If you just set the volume to that attribute it will be the opposite of what you want (i.e. louder the farther away you are) so you will need to have some number (experiment with it) divided by game.sounddistance.

good luck! Sounds very interesting!

Cheers Sci! I will give this a go!

"so you will need to have some number (experiment with it) divided by game.sounddistance."
How would I write this? I have game.soundDistance /2
Is that correct?

TouchTiltGames

Yeah I think this is a bit beyond me...

On my actor that plays the sound I have:
Game.soundSourceX to: self.positionX
Game.soundSourcey to: self.positionY

In the PlaySound behaivor I have Game.SoundDistance in the Volume.

In the moving actor I have:
Constrain: Game.soundDistance to: magnitude(self.positionX-game.soundsourceX, self.positionY-game.soundsourceY)

Not sure this is working properly..hehe.

made a demo for you

Ok so how does one download templates now on the new site? I havent downloaded any since the ol' days of right clicking on the link and saving as...
