The upper range of the constraint.

By setting this value, you are disabling the use of the restLength property, so it's good practice to set both the min and max values at the same time.
Note that valid values are always positive values.
In order to disable the maximum bound, set this property to a negative value.

The lower range of the constraint.

By setting this value, you are disabling the use of the restLength property, so it's good practice to set both the min and max values at the same time.
Note that valid values are always positive values.
In order to disable the minimum bound, set this property to a negative value.

The length that the constraint will attempt to maintain.

For spring and stick constraints, this represents a pixel distance
For angular constraints, this represents a degree value between 0 and 360.
For more information about angle measures in angular constraints, see the documentation for the AngularConstraint class

Note that by setting this value you disable the use of min/max values (in other words, the constraint is no longer bound to a range, but only one value)

Creates a SpringConstraint object.

A static method for quickly constraining a list of objects to eachother.

   var box:FisixObject = new FisixObject()
   var p1:CircleParticle = box.newCircleParticle(0,0,20)
   var p2:CircleParticle = box.newCircleParticle(20,0,20)
   var p3:CircleParticle = box.newCircleParticle(20,20,20)
   var p4:CircleParticle = box.newCircleParticle(0,20,20)
   
   //you can constraint all these particles like so:
   SpringConstraint.constraintAll(box.particles)
   //or like so
   //SpringConstraint.constraintAll([p1,p2,p3,p4])
   

A static method for quickly constraining a list of objects in a chain. The first particle will be constrained to the second particle, which will be constrained to the third particle, and so on...

   var box:FisixObject = new FisixObject()
   var p1:CircleParticle = box.newCircleParticle(0,0,20)
   var p2:CircleParticle = box.newCircleParticle(20,0,20)
   var p3:CircleParticle = box.newCircleParticle(20,20,20)
   var p4:CircleParticle = box.newCircleParticle(0,20,20)
   
   //you can constraint all these particles like so:
   SpringConstraint.constraintChain(box.particles)
   //or like so
   //SpringConstraint.constraintChain([p1,p2,p3,p4])
   

A static method for quickly constraining two lists of of objects to eachother. All the objects in the first list will be constrained to all the objects in the second list.

   var box:FisixObject = new FisixObject()
   var p1:CircleParticle = box.newCircleParticle(0,0,20)
   var p2:CircleParticle = box.newCircleParticle(20,0,20)
   var p3:CircleParticle = box.newCircleParticle(20,20,20)
   var p4:CircleParticle = box.newCircleParticle(0,20,20)
   
   SpringConstraint.constraintTwoLists([p1,p2],[p3,p4])
   //note that p1 and p2 will be constrained to p3 and p4
   //but p1 won't be constrained to p2, and neither will p3 be to p4
