Optionally, the above-mentioned landmark information may be a 3D virtual model used to represent the sub-map entrance. When the player is playing the game, the marker information can enter the corresponding sub-map in response to the game player's operation instructions.

It should be noted that in related technologies, there is usually a world map that provides map guidance for players. Figure 4A is a two-dimensional world map in related technologies. As shown in Figure 4A, the world map is usually a two-dimensional flat map. Figure 4B is a two-dimensional world map with a three-dimensional concept in related technologies.

However, this display method guides the map, which is difficult to stimulate the player's desire to explore and affects the user's gaming experience.

However, in the embodiment of the present disclosure, although the above-mentioned landmark information is used to represent a sub-map entrance, the landmark information does not prompt the user that this is a sub-map entrance like a traditional guidance map. For example, when the user will When the mouse or finger selects the submap entrance, the model here will become larger, or special marking symbols, such as circular buttons and related text descriptions, are set at the submap entrance. Therefore, in the embodiment of the present disclosure, the landmark information and the target virtual model are visually integrated.

For example, the three-dimensional guidance map may include complete geological information of the mountain surface, and a specific internal map of the mountain may It is in a certain sub-map, which can include elements such as hot springs and fire.

In order to save energy consumption, when the above-mentioned three-dimensional guidance map is used on a mobile terminal, it only retains the characteristics of the geographical environment and does not include elements unrelated to guidance, including specific features such as the storyline of the game, buildings, vegetation and props. For example, it can be represented by green Vegetation, but do not draw specific trees and grass. If you need to draw landforms such as volcanoes, deserts, and neighbors, you can represent volcanoes through burnt land and lava, and deserts through yellow and hills.
