Floor Constraint?

Hey guys, I was intending to brush up on the floor constraint, but I can’t find the documentation. Anyone remember what release it came out in, or where the documentation is? Thanks in advance.

It was introduced with 2.40

The way it works:

  1. Apply constraint to object (or bone).
  2. Choose target.
  3. Choose: X,Y,Z,-X,-Y,-Z. Default is Z.

Z will not allow the constrained object to pass below the target object.
-Z will not allow it to go above the target.
X,-X,Y and -Y will do the respective actions on the global X and Y axes.

Useful for placing a “floor” or “walls” for objects and armatures. Apply to armature foot bones to prevent them from slipping below the floor.

Note for bones: Like other constaints that affect position, this constraint will only change the translations of translatable bones, i.e. root bones. Non-root bones which are part of an IK chain will not be affected directly, although they will of adjust themselves if the constraint is applied to the target of their IK chain

New features added: offest and sticky. “Offset” makes the constraint take effect at “offset” distance from the target, useful for setting heel thickness, etc., without adjusting skinning or rig. “Sticky” toggle make the constrained object stop moving entirely at the point where it passes the floor object, remaining “stuck” until it is unconstrained again.

thanks for the informative reply, everything is working as it should now.
