thanks! But what I mean is to change an attribute if the selfposition was NOT changed after 5 seconds.

Well I guess Im completely missing your issue here. The project you uploaded works just fine. I even changed the loading attributes around using the same key and still it worked. Yes I changed the att

For attribute A , the reason to save in key B and C is that I consider A as some kind of "constant"
