Abstract: In a data processing method, a query distance range is determined based on current position information of a character controlled by a user in a virtual scene. Data for a plurality of non-player characters (NPCs) from a database is determined based on NPCs to be placed in the query distance range. The data includes a plurality of attributes respectively corresponding to each of the plurality of the NPCs. Weights are determined for each of the plurality of NPCs. A first number of NPCs is generated based on a descending order of the weights for each of the plurality of NPCs. The first number of NPCs is a subset of the plurality of NPCs. The generated first number of NPCs are transmitted to a client controlling the player-controlled character to cause the client to display, in the query distance range, virtual images corresponding to the first number of NPCs.
