For everybody who just want to know how to make a request to control the application via Postman here you have the right PUT for your Postman-Collection (Body/Raw/Json):
http://localhost:30010/remote/object/call
{
“objectPath” : “/Game/Scene_Folder/Scene_Level.Scene_Level:PersistentLevel.Actor_Name_2”,
“functionName” : “Function_Set_Values”,
“parameters”: {
"Light_Red_Strenght": "2.5",
"Light_Green_Strength": "4.3",
"Light_Blue_Strength": "50",
}
}
IMPORTANT:
The Backend REST API works in unreal only with functions. So don’t use Custom Events.
If you want that others IP-Devices from a network can access your application you need add this to the DefaultEngine.ini
DefaultBindAddress
[HTTPServer.Listeners]
DefaultBindAddress=0.0.0.0
