eval? (at least, that was it in flash)
« on: Apr 22nd, 2004, 7:41pm » |

Hey all,
I've got a little problem. I've made some sonia samples, named a,w,s and d. The idea is to link em to the keys.
So when i press a, i want to hear sample a.
I'd prefer to do this dynamicly instead of writing an if statement for each key.
something like [key].setVolume(1)
any ideas?
Thanks,Tim

You can't do it that specific way in Java.
One way to do it would to be to create an array of samples, say 128 of them:
(I don't know the sonia keywords, so I'm guessing here)
SoniaSample[] Sounds=new SoniaSample[128];
Sounds['a']=LoadSound("whatever");
Sounds['w']=...
etc
Then have:
if(keypressed)
{
Sounds[key].setVolume(1);
}
In this way the key you press is used as the index into the array of sounds, which works because you can use "key" as an int.
However, this method isn't very efficient, you have 124 unused samples sitting around.

I managed to do it without eval 
I made a few arrays, one with the keycodes of the keys i want to use, and i combined that with an array that checks if a key is toggled.
Great my first real processing thing is done 
Cant show you alas, its on my internetless laptop at the moment.
And it really aint that spectacular either
Thanks
Tim
