behavior - change color of a colorCube from dynamic inputs in java3D -

i'm able alter color of cube @ beginning. want alter according changing value dynamically if run next code color of cube greenish , not alter 1 time again since run 1 time. wondering if there's way alter colors few times using class extends behavior. please allow me know i'm missing. thanx in advance.

protected branchgroup getcube() { branchgroup bg = new branchgroup(); boundingsphere bounds = new boundingsphere(new point3d(0.0, 0.0, 0.0), 10000.0); tg = new transformgroup(); t3d = new transform3d(); t3d.settranslation(new vector3d(-35.0f, -15.0f, 40.0f)); tg.settransform(t3d); cc = new colorcube(3.0); simplebehavior4d3 b = new simplebehavior4d3(tg, gui);//changes position of cube b.setschedulingbounds(bounds); b.setenable(true); tg.addchild(b); quadarray cube = new quadarray(24, quadarray.coordinates | quadarray.color_3); cube = (quadarray) cc.getgeometry(); cube.setcolors(0, creategreen()); if (b.liftcapacitystat().equals("full")) { cube.setcolors(0, createred()); } else if (b.liftcapacitystat().equals("half")) { quadarray cube1 = new quadarray(24, quadarray.coordinates | quadarray.color_3); cube1 = (quadarray) cc.getgeometry(); cube1.setcolors(0, createyellow()); } tg.addchild(cc); bg.addchild(tg); bg.setuserdata("cube"); homecoming bg; }

here code:

(note snippet

final geometryarray geometryarray = gi.getgeometryarray(); { geometryarray.setcapability(geometryarray.allow_color_read); geometryarray.setcapability(geometryarray.allow_color_write); }

and part interpolator defined

final interpolator colchange = new interpolator() { ....
