We discretize the wave equation with cubic nonlinearity along one of the two light-cone coordinates. The resultant semi-discrete equation exhibits discontinuous solutions in addition to the usual solitons. We interprete these as envelope solitons. We also discretize a complex wave equation with cubic nonlinearity and give its soliton solutions.
