Fixed path transitions in a virtual universe environment are provided. In one embodiment, tracking data that identifies a location of an avatar in relation to a range of an object in a virtual universe is received. The range comprises a viewable field. In response to the tracking data indicating an occurrence of a trigger condition associated with a fixed path rule, a fixed path defined by the fixed path rule is identified. A speed of movement and an orientation of the object associated with the fixed path rule is identified. Movement of the object along the fixed path defined by the fixed path rule is initiated. The object then moves along the fixed path at the identified speed and with the orientation associated with the fixed path rule.
