Abstract: In a method for synchronizing character display, motion data of a first character over a time period is obtained. A first phase parameter for the first character at an end of the time period is determined based on the motion data and a standard action cycle for a current action that is performed by the first character. A second phase parameter from the second terminal is received. The first phase parameter is adjusted based on the second phase parameter to obtain a third phase parameter. Updated motion data for the first character is generated based on the third phase parameter. The first character is displayed based on the updated motion data.

A database system receives a user application and identifies, via hardware processors, multiple package dependencies required by the application, including at least a first and a second package dependency. Upon receiving a database statement from a user that invokes these dependencies, the system retrieves the necessary packages from a repository. It then creates a first execution environment incorporating the first package dependency and a second execution environment with the second package dependency. Utilizing the multiple execution environments, the system generates results data in response to the database statement, effectively managing and executing user-defined functions that rely on different versions or types of package dependencies within a unified database framework.
