[Playerstage-users] blob_count does not reset to zero

[Adam R. <ra...@au...>]

I am using the Blobfinder Proxy in a Stage simulation (player version
1.6.4 and stage 1.6.2) and whenever all of the "blobs" leave the
camera's field of view, the blob_count does not reset to zero, but
remains at 1 (or 2 if two blobs left the field of view at the same
time).  And when I access the attributes of the non-existant blob[0],
they are not reset either but are stuck on the last updated blob
information.  So how should a robot know if there are no blobs in the
field of view?

I wrote a small program (assuming that all blobs are in constant
motion) that will ignore a blob if the blob's attributes are not
changing.  But there must be a better way.

Any suggestions?  Thanks,

Adam
