How to make a rigid line with more than 3 particle?

[iiley Chen]

Hi guys,

I'm trying to make a game with APE, now i have to make a rigid body
with more than 3 particle, you can assume i want to make a wand, and i
may give force to some point of this wand, so i need to create it with
particles and connected with constraints. But APE just provide
SpringConstraint, it is soft, make my wand just like a rope. Is there
some right way to achieve this?

Thanks in advance!!

My problem seems to be easier than that! I cannot for the life of me
create a chain of multiple groups tied together with springs. At
first it works, but after a few, the weight seems to be so much that
the spring's length grows tremendously, even when the stiffness is set
to 1. What am I doing wrong? Should I be using something else
instead of springs?

Thanks!!

Make sure your particles are set fixed = true.

So if you have circle particles.
CircleParticle(x, y, radius, fixed, mass, elasticity, friction)
the 4th param should be true.
