ParticleString2D missing constructor? #23

Closed aunruh closed 11 years ago

aunruh commented 11 years ago

Hi! When I initialize a ParticleString2D this way: ParticleString2D(VerletPhysics2D physics, java.util.List<VerletParticle2D> plist, float strength)

Then println(physics.particles.length); or println(physics.springs.length); returns 0. Is the constructor not yet implemented or am I doing something wrong?

The other way works perfectly: ParticleString2D(VerletPhysics2D physics, toxi.geom.Vec2D pos, toxi.geom.Vec2D step, int num, float mass, float strength)

Why do I want to use this constructor? The particles in java.util.List<VerletParticle2D> plist have specific coordinates. This way i'm not constricted to using toxi.geom.Vec2D step and toxi.geom.Vec2D pos for the positioning of the particles.

Cheers

Ok it works! I just added my particles and springs directly to the VerletPhysics object. Instead of making a ParticleString object. :)

This unit test for the constructor passes. The array of particles, and the created springs end up in the physics object correctly:

Are you using this within Processing.js with the Processing/Java syntax? If so, maybe you are passing it a java collection? toxiclibs.js always wants a normal Array.

Oh, yeah that must have been the problem. Didn't use the proper array. Thanks!
