I was trying to build a character like a ghost follower dude that hovers around my player and follows him as he moves through the level. I wanted sorta random hovering movement around the 2d sprite...I thought a spring joint 2d would be good place to start but it seems that the fact it needs a rigid body it really wonks with the other character as he moves (and changes his behavior and physics and forces a lot)...I even set the mass of the follower around to 0 on the rigid body ... no go. So is the wrong tree to bark up? Think of a fairy hovering around the head of the player ..that is basically what i want (with it having semi random movement or movement that is reactive to what the player is doing). As I type this, sounds like I am going to have to script this myself and I have no idea where to start.
