How to verify the rosbridge-UE4 connection: Make sure UE4 is configured to use the ROSIntegrationGameInstance (see below) and set the connection parameters. Report Save. Since network projects differ in their development and performance requirements, it is often necessary to work with simpler objects, such as UObject classes, but their functionality is initially truncated, which can create a strong framework.
