hey it is simple make the blade have heterocollide := true make the target have the same, than make a ball some where on the blade go to script menu and write (in oncollide)

e.this.density= +inf that will do it but it wont make it follow the thing if moving it then you have to spawn some hinges or so but that is a bit harder to make them hit the right place that will need some self made variables hope it helped if not add me on skype my name is casper418161

and if you am going to give someone credits for the script/idea give it to raydeg/rideg he made it first I think there is a link to his scene in some of the alike scenes
