View Full Version : Nurb Curve to have a Locator as a goal

Any ideas on how to get my "controller curve" for my rig to have a simple goal?

I tried parenting the controller curve to a shape, turned shape active rigid, and gave it a newton field. This works ok, but it lets the object rotate, which I don't want. I want it to simply "ease towards" the destination.

Much like creating two particles and giving one a goal, and goal weighting to the other...
// Create particle systems
particle -p 5 0 -5 -n partOne;
particle -p -5 0 5 -n partTwo;

// Set rendering type to sphere
setAttr partOne.prt 4;
setAttr partTwo.prt 4;

// Add goals to each set of particles: 1 to 2, 2 to 1
goal -g partTwo -w 0.2 partOne;
goal -g partOne -w 0.2 partTwo;

// Set goal smoothness for each goal to create 'curved' transition (easing)
setAttr partOneShape.goalSmoothness 4.0;
setAttr partTwoShape.goalSmoothness 4.0;

Hey Mleep.

Why dont you just point constrain your controller to your rigid object? That way you get the translations, and ignore rotations.

Good Luck,

I need the particle and goal behavior, point constraints, etc do not provide easing and goal weighting behavior.

OK, You may want to explain yourself better. Because from the looks of this quote, it seems that you tried parenting a curve to a rigid body and were overall happy aside from the rotation.

Ok...So to solve your problem.
Create a single particle using the particle tool. In the connection editor, connect the particle's center to the controller's translate. Then set a goal for that particle.
