Custom goal to snap beyond a collision particle

by Ramon van der Heijden

Dec 20, 2016

Hi.

I have a simple problem that I can't seem to get to work. I need 2 points to maintain a minimum distance from each other, and move only on the Y-axis. One point should be fixed and one point can move.
However, the trick is: if the floating point is within the critical distance to the fixed point, it should always move down, beyond the fixed point and then aim for the minimum clearance. <edit> See the illustration below.
The last part, I cannot figure out, even with a custom goal.


Any suggestions?

    1. fix the point to remain fixed

    2. rest length = r+r distance. 

    you need to explain further, like what approach your using, what components your using. I am assuming your using kangaroo ?
