Hi everybody, I have a problem using TVector2. In the attached program I want the value of the vector 'v1' to change after have used the operator '-=', but as u can see if you run the program nothing happens. Ofcourse this is just a stupid pointer-referens misstake made by me, but all other ways with the pointers and references I've tried have just given me the error message *** Break *** segmentation violation or something similar. If anyone could found out the correct way to use TVector2 in my program I would be very glad. Cheers / Christian Hansen # include <math.h> # include <iostream.h> gSystem->Load("libPhysics"); void test() { TVector2 *v1 = new TVector2(4, 2); TVector2 *vunit1 = new TVector2(0,0); *vunit1 = v1->Unit(); cout << "Before Vx = " << v1->X() << endl; &v1 -= &vunit1; cout << "After Vx = " << v1->X() << endl; }
