Unreal engine developing.

Hello If you don't have unreal C++ developing result, Don't bid. If you know unreal engine and you have C++ previous developing result, please bid. The spec is as following: First, data 1, support the terrain data, texture data block dynamic loading scene or delete from the scene, the data source for the TIF or the corresponding format of the binary data; 2, the height of the terrain is divided into the absolute height and relative height, relative height refers to the relative height, the absolute height refers to the relative height of the world coordinate system, all models should be highly model attributes, can set the height model. 3, can get a point of the ground height and the height of the ground model Two, resource management 1, all resources can be imported from outside, not in advance. 2, model resources can only support FBX 3, the model is divided into two kinds of mobile and can not move, the default is to move Three, interactive data 1, all the features of the scene are able to remote operations, including mobile, switch lenses, mobile scene model, etc. A, the camera to move the model includes four kinds: free cruise, lock the target, positioning. The corresponding JSON statement is: { "Manipulator": { "Type": "freeCruise" } }; B, when the cruise mode is to lock the target, the additional parameters for the target model ID, distance (unit m), the relative target of the pitch angle and azimuth angle. Moving target, the relative position of the lens will not change, it will follow the move. The corresponding JSON statement is: { "Manipulator": { "Type": "freeCruise", "Args": { "Id": "id1", "Distance": 100, "Pitch": 90, "Azimuth": 0 } } }; C, when the cruise mode for positioning, the corresponding parameters for the lens center corresponding to the position (x, y, H), the relative position of the distance (unit: m), the relative position of the pitch angle, the relative position of the azimuth angle. The corresponding JSON statement is: { "Manipulator": { "Type": "freeCruise", "Args": { "POS": "15,50,50"" "Distance": 100, "Pitch": 90, "Azimuth": 0 } } }; D, model attribute settings { "ModelProperty": { "Id": "modelId", "POS": "x, y, z", "Rotate": "x, y, z", "Selectable": "false", "Movable": "true", "Scale": "1", "ModelFile": "c:/[login to view URL]", "LOD": 100010000", "Type": "ship"" } } Model types (type) are mainly ship, helicopter, plane, car. E, set the environment, rain, snow, cloud maximum value is 100, the minimum value is 0, corresponding to the JSON statement: { "Environment": { "Rain": 5, "Snow": 30, "Cloud": 15, "Time": "17:05" } } All of the above properties range is 0--100. F, model combination { "CreateGroup": { "Id": "groupId", "Chieldren": "modelId1, modelId2" } } { "DeleteGroup": { "Id": "groupId" } } The combined model of the model is consistent with the basic properties of the common model, and the method is the same; G, some of the basic functions of the call for example: { "FunctionName": { "ArgName1": "groupId", "ArgName2": "modelId1, modelId2" } } 2, support the mouse to drag and drop the part of the model in the scene. The model will have the corresponding parameters (canMouseMove) that the model does not support the mouse to drag and drop, to support the true. To support the movement of the model only need to ctrl+ the left mouse button to move the model; 3, support model selection, left click on the mouse model for selecting a single model, the left mouse button to choose shift+. And the model texture of the overall color, corresponding to the JSON format is as follows (where the color can be used R, G, B, a, can also be expressed with an integer): { "TranslateColor": { "Id": "modelID", "Color": "200200200100", "Color": 3368601700 } } 4, the function call is divided into two ways, one is the network data, the basic format is JSON; the second is the C++ interface, C++ interface is the analysis of the JSON interface.
