[chuck-users] how do I assign a Blit array with a BlitSquare array?

[Casper Schipper]

Hello George,

You have an interesting point there. I wanted to suggest to you that you wrap your BlitSaw in an extension of a Chubgraph class, but that also doesn't work!
It appears to me that Chuck in general doesn't let you assign arrays from subclasses to superclasses: a bit of a surprise indeed!

For example :
class ClassA {
    float v;
    fun float value() {
        return v;
    }
}

class ClassB extends ClassA {	
    fun float value() {
        return v * 2;
    }
}

ClassA myObjectA;
ClassB myObjectB;

//ChucK allows: 

myObjectB @=> myObjectA;

//but does not for arrays :-(

ClassA myObjectArrayA[10];
ClassB myObjectArrayB[10];

myObjectArrayB @=> myObjectArrayA; // gives error 

Of course there are less pretty ways of achieving what you need, probably by just switching the routing of the UGens :
BlitSaw blitSaw[10];
BlitSquare blitSquare[10];

Gain output; // => or the rest of your patch

for (int i;i<blitSaw.size();i++) {
	blitSquare[i] !=> output;
	blitSaw[i] => output;
}

for (int i;i<blitSaw.size();i++) {
	blitSaw[i] => output;
        blitSquare[i] => output;
}

Happy chucking!
Casper
