Re: [PD] Data Structures - Delete specific scalar?

[João Pais]

Hi,

I looked at your sequencer. I didn't play around with it, but I wonder if  
you are better off using an array instead of X scalars? As I suggested  
before, you can use a variable to decide if the data is active or not,  
it's not really necessary to erase it from the patch. Also on the  
graphical side, it should be possible to hide individual array elements  
using the -v command (or not? I didn't try yet, but it works with  
individual scalars).


João


Is there any message based way to delete a scalar?

As I presume what people usually do is select the graphic in the  
datawindow and

delete it this way. I need to do this without the graphical selection.

I'm currently using data structures just as a multi-dimensional storage  
object

(the graphical side doesn't concern me). I've developed [data/drip] and
[data/filter] patches akin to [list-drip] and [list-filter]. I'm now  
looking to
create an object where I can remove specific scalars based on whether or  
not

their value fields match a certain condition (via [data/filter]).


Thanks in advance as always,
John.

Thanks João,

I'm looking into a brute force workaround whereupon I drip the data structure 
and copy it to a buffer structure but with the scalars that I want to delete 
filtered out - then I clone this buffer back to the original thus deleting 
certain scalars. This should work for my needs.

Also as an aside, I'm just reading Frank's data structure tutorial patches (I'm 
a beginner to this topic!). I really think that these should be added to the 
official vanilla documentation.

Cheers, John.
