RB Constraint Linear movement

[afx]

How can you stop and/or limit movement of a KActor using an RBConstraint?

What I mean by limit movement is a way to specify bounds in which the KActor cannot move past. If the KActor reaches these bounds, all movement should stop immediately.

I'm using the PhysicsGun with a KActor constrained to a HingeActor that can only move on the Y-axis, and I want to constrain this KActor not to past Y=128 units.

Thanks!

Ok well I found out that you can restrain movement within a radius by setting bLimit to 1 and LimitSize to a number. The affected KActor won't move out of this radius. However, I don't want the KActor to be able to move forward/backward in its starting place, but only forward to the LimitSize number and then be able to go backwards to its starting position. I hope that made sense..

I look at the RB_ConstraintSetup.uc and found where it's assigning the LimitSize numbers. It says it can be shifted by "fiddling Pos1/2". I have no idea what this means.

struct native LinearDOFSetup
{
	/** Whether this DOF has any limit on it. */
	var() byte			bLimited;

	/** 
	 *	'Half-length' of limit gap. Can shift it by fiddling Pos1/2.
	 *	A size of 0.0 results in 'locking' the linear DOF.
	 */
	var() float			LimitSize; 

	structdefaultproperties
	{
		bLimited=1
		LimitSize=0.0
	}
};

I found Pos1/2 in the defaultproperties:

defaultproperties
{
	Pos1=(X=0,Y=0,Z=0)
	PriAxis1=(X=1,Y=0,Z=0)
	SecAxis1=(X=0,Y=1,Z=0)

	Pos2=(X=0,Y=0,Z=0)
	PriAxis2=(X=1,Y=0,Z=0)
	SecAxis2=(X=0,Y=1,Z=0)

	LinearBreakThreshold=300.0
	AngularBreakThreshold=500.0
	
	PulleyRatio=1.0
}

But any value I put in for them has no effect on the LimitSize radius.

A picture since this is kinda hard to explain.


I only want LimitSize to go in one direction, not in both.

Thanks.
