Abstract: A navigation path determining method and apparatus, a device, a storage medium, and a program product are provided. A navigation grid map is obtained corresponding to an application. The navigation grid map is marked with a primary region and a secondary region. A passage level of the primary region allows passage of virtual objects under volume levels. The secondary region includes a plurality of sub-secondary regions at different passage levels. The passage levels of the sub-secondary regions correspond to different maximum volume levels. At least one guide grid corresponding to the target grid is obtained for a target grid corresponding to a target virtual object. The target grid is located in the secondary region. Based on the guide grid, a navigation path of the target virtual object between the target grid and the primary region is determined. The present subject matter can ensure non-clipping of virtual objects.
