In the attached folder, "help me.pd" contains four instances of the abstraction "block-creator" which uses bangs to create and destroy instances of "block0" "block1" "block2" etc. in a unique subpatch called $0-vblock.
The important part is that the subpatch $0-vblock is unique in each instance of "block-creator". So creating and destroying the "blockn" abstractions in one instance doesn't affect the others.

It took me a long time to work out a way to get this to work using [f $0] and banging it into messages. I'd just like to know if there's a simpler way to do this that I've missed.helpme.zip

@nuromantix A little bit simpler is to use $0 in objects, in this case [send].

You can do it like that:

[2\
|
[obj 50 50 block$1(
|
[s pd-$0-vblock ]

Another way to simplify is to send multiple messages in one go. This can get more confusing, but takes less objects.

block-creator.pd (updated)

Thanks. I forgot you could bang a message into a SEND to create objects. Also I never would have figured out you need a - between pd and $0-vblock in the SEND object!!

@nuromantix Right, this is not intuitive. But [send xy] and [; xy( are actually just two ways of the same thing
