sprite - How to set position of a dynamic body in andengine? -

-

i'm developing game using box2d. have move ball according accelerometer. have created body n connected ballsprite it. i'm moving body using setlinearvelocity(). once ball reaches boundaries of screen,i want stop movement of ball @ edge of screen. how do this?

public void onaccelerationchanged(accelerationdata arg0) {     ballbody.setlinearvelocity(arg0.getx(), 0);    }

you can set body velocity 0 when reach boundaries.place condition in update handler , place below statement

 body.setlinearvelocity(0, 0);

(or) can make the body type static 

  body.settype(bodytype.static);

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
