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