automate selection of media from library on hardrive

Apr 24 2009 | 12:33 pm

hi –

How do i randomly automate the opening/reading of data (images, video, music) from a file on my hardrive?

i.e i have a movie object and on command, the read function will look to a file on my hardrive with many video’s in it, and on account of some random number select a video and open it.

Something like this will let you select a random file from a folder:

here is another way of doing it, based on the same idea. but here you can see the data and choose it manually or randomly (if you hook up your random number generator to a [send selCell] object or the right inlet of the bpatcher).

happy patching Smile

Open the umenu inspector, Files tab, look at "File types". For the moment, umenu is filtering, and accepting only .mov files. Erase to accept all files in a folder, regardless of type.
