I seperated the two objects by moving the Body along the X axis with the appropriate dial. The target was at 0, the follower at... possibly not enough? Let me try again and increase the seperation to make them several bodies apart (I'll do this later). The aim was for swimming, actually - I have a "swim cycle" that I want to make, but I need to fine-tune how I'm going to be able to apply it. This script should be significantly better for my purposes than Walk Designer, but I need to make sure that I can make it work first :( I'll report back, hopefully tonight. Cheers, Cliff
