AirSim Code Flow

The goal of this page is to document the different entry points to the AirSim plugin from Unreal Engine.

AirSim Code Flow

Need to figure out how to instantiate the API from within the Unreal environment. This will allow us to embed DroneBlocks directly into the game and send commands without having to go through the RPC server. Not sure if this is possible.

This is the entry point into the AirSim Game Mode:
