Skill measurement systems and methods include interaction pairs and an interaction uncertainty. The interaction pairs are pairwise matches corresponding to instances of interactions between players. The interaction uncertainty variable corresponds to the instance of interaction and is based in part on the uncertainties of a player, player team, and/or gameplay aspects. The interaction pairs and interaction uncertainty are used to more accurately determine a skill rating of a player based in part on interaction data among gameplay data from a gameplay session of a video game.

This application discloses a method and apparatus for rendering weather in a virtual environment, a device, a medium and a program, belonging to the art of image processing. The method includes the following steps: acquiring at least one weather map of a weather scene in a virtual environment (201); removing a first weather map from the at least one weather map to obtain a remaining second weather map (202); and rendering the weather scene in the virtual environment according to the second weather map (203). This method reduces the frequency of map sampling by reducing the number of weather maps, and improves the performance of a terminal when running an application program supporting the virtual environment.

This application provides a method and apparatus for using a virtual item, a device, and a storage medium, and belongs to the field of application programs that support a virtual chessboard. The method includes displaying a virtual chessboard and a virtual item bar in a user interface, a virtual chess piece located on the virtual chessboard and being a virtual character having permission to use a first virtual item, and the first virtual item being displayed in the virtual item bar; moving the first virtual item on the user interface following a drag operation, the drag operation being on the first virtual item; and assembling the first virtual item to the virtual chess piece and performing a first vibration reminder in response to the drag operation being stopped in a display range corresponding to the virtual chess piece.
