The method includes: displaying a virtual scene interface, the virtual scene interface including a first virtual object, second virtual objects, and ability controls; determining, in response to a first trigger operation on a first ability control, a target virtual object from the second virtual objects and according to the first trigger operation, and controlling the first virtual object to cast a first ability on the target virtual object; determining the target virtual object as an ability casting target corresponding to a second ability when a second trigger operation on a second ability control meets an ability continuous casting condition, the second trigger operation being triggered during ability casting of the first ability; and controlling the first virtual object to cast the second ability on the target virtual object.

Virtual object control method and apparatus, terminal, and storage medium

Provided are a virtual object selection method and apparatus, a terminal, and a storage medium, belonging to the field of computer and Internet technologies. When a client controls a first virtual object to perform a first operation, and a plurality of second virtual objects are distributed densely in an execution range of the first operation, the client offsets logical positions of the plurality of second virtual objects to ensure that the plurality of second virtual objects may be distinguished and a target virtual object is selected from the plurality of second virtual objects based on offset logical positions. Accordingly, a user is prevented from spending much time to select the target virtual object from the execution range of the first operation, thereby reducing operation time costs of the user and improving the operation efficiency.
