The embodiment of the invention provides an operation control method and device for a target object. The method comprises the steps that after the target object in a scene is displayed on an interactive interface, touch operation by a user on a first point of the interactive interface is detected; according to a first movement track of a touch point on the interactive interface, a second movementtrack of the target object in the scene is determined; the starting point of the first movement track is the first point; and movement of the target object along the second movement track is displayedon the interactive interface, wherein the first movement track and the second movement track are not completely overlapped on the interactive interface.
