For pion masses ranging from $m_\\pi=265$ MeV to $m_\\pi=437$ MeV, we determine the energy spectrum in the centre-of-mass frame and in three moving frames. We obtain the scattering phase shifts using L\\\"uscher's finite-volume quantisation condition. Fitting the dependence of the phase shifts on the scattering momentum to a Breit-Wigner form allows us to determine the resonance parameters $m_\\rho$ and $g_{\\rho\\pi\\pi}$.
