Current coordinate) * A slow constant (0 For example:There is a video clip on the stage. The instance name is mc and it is moved to the position x = 400, y = 300.Mc. Tox = 400;MCS. Toy = 300;Mc. onEnterFrame = function (){This. _ x + = (this. Tox-this. _ x) x 0.3;This. _ y + = (this. Toy-this. _ y) * 0.3;// Update the coordinates of each instance,
