Playing with Dynamic Array |
  |
|
As I'm getting very interested in using the new ChucK 1.2.1.2's dynamic array feature especially for building more complex data structures,
I've started this topic so we can share about this feature.
Today, I'm try adding array members:
| Code: | int a[0][0]; // start with a blank a[][]
<<< "int a[0][0];", "" >>>;
a << [1] << [2, 3]; // add [1] and [2, 3] to a
<<< "a << [1] << [2];", "" >>>;
a[1] << 4; // add 4 to a[1][1]
<<< "a[1][1] << 4;", "" >>>;
<<< "a.size(): ", a.size() >>>;
<<< "a[0].size(): ", a[0].size(), " a[1].size(): ", a[1].size() >>>;
<<< "a[0][0]:", a[0][0] >>>;
<<< "a[1][0]:", a[1][0] >>>;
<<< "a[1][1]:", a[1][1] >>>;
<<< "a[1][2]:", a[1][2] >>>; |
From the code, we start with a[0][0]
and after adding [1] and [2, 3] to a
we have a[0] and a[1] that each has different size,
so actually we have just grown a tree with different number of leaves between different branches.
This is such a nice thing we can do in ChucK!
. . .
Feel free to share more about arrays. |

I don't know if it is normal, but on Windows I can't run this code inside MiniAudicle. I get this error:
[unnamed1]:line(4): cannot resolve operator '<<' on types 'int[][]' and 'int[]'
Anyway, it works fine from the shell.

Oh.. the operator << (add new member to the array, thus increase that array size by 1) ..
is a new feature in ChucK 1.2.1.2..
but current miniAudicle on the website has ChucK 1.2.1.1.
I was compiling miniAudicle but replacing the whole chuck source code with 1.2.1.2 so I can run 1.2.1.2-compatible code in miniAudicle.
So I guess, for you, if you still don't compile miniAudicle for windows,
you might have to try this with command-line 1.2.1.2 ChucK for now.
I hope we'll have the new miniAudicle executable up at ChucK's web soon. |

Yes. It simply works right away. I was compiling in Linux.
First, I extracted miniAudicle source,
then delete all files in chuck-1.2.1.1,
and repleace with ones from chuck-1.2.1.2's sourcecode package,
then compile.
THe Help -> About also shows the correct ChucK version. |

This is one thing I tried with dynamic array:
It might become quite useful and easy.
It's adding members to 2D array,
and the good thing is that...
for example if we have int A[4][0];
each A[i] is independently sizable.
so by this, we can create more flexible tree structure array.
an easy example:
| Code: | int melody[0][0]; // new melody buffer
for(int i; i < 10; i++)
{
melody << [0];
// increase melody size for a set of new members
// add more members
for(int j; j < Std.rand2(3, 12); j++)
{
melody[i] << Std.rand2(0, 12); // add new note
}
}
Flute s => dac;
for(int i; i < 10; i++)
{
for(1 => int j; j < melody[i].size(); j++) // skip the first member '0'
{
melody[i][j] + 60 => Std.mtof => s.freq;
.2 => s.noteOn;
150::ms => now;
.2 => s.noteOff;
}
second => now;
} |

I have not yet found a need for this feature but I like the fact that we can make tree structures out of arrays. I'm sure there are fascinating things that we can do now that were not possible or practical before.
