Simulation global small map dynamic generation method based on UE

The invention provides a simulation global small map dynamic generation method based on UE, which comprises the following steps: establishing an information storage library, establishing a map information setting interface for external calling in UE, inputting data in the information storage library to the map information setting interface, and establishing an interface which is externally called and is used for displaying the marking picture of the combat unit in the scene in the small map in the UE, and updating the position of the combat unit in the small map. Small map pictures and pixel information of different scenes are stored in an array, a set of complete small map display interface is manufactured, and calculation such as small map picture loading and small map scaling in the interface is opened to the outside in an interface mode. When different scene maps are loaded, only corresponding different scene map information needs to be provided for the interface, and small maps do not need to be drawn in
