Information processing device, control method for information processing device, program, and information storage medium for determining collision between objects on a display screen

Abstract

To provide an information processing device capable of ensuring not to execute processing not intended by a user in a case of stopping the ongoing operation after selecting an object (for example, in selecting again an object other than the object already selected, or the like). In a case where one of a user's designated position is included in a determination area based on the position of one of the plurality of objects displayed in a screen, an object moving unit () moves the one object based on the one designated position. In a case where the object moving unit () moves first and second objects, a collision determination unit () determines whether or not the first and second objects have collided. A processing executing unit () executes processing relevant to the first and second objects based on a result of determination by the collision determination unit ().
