Turtle Rock Studios, known for games like "Left 4 Dead," "Evolve," and the "Counter-Strike" series, has also ventured into virtual reality (VR) development. The studio has brought popular VR games like "Journey of the Gods" and "Face Your Fears 2" to the VR community. Recently, Brock Heinz from Turtle Rock Studios shared a series of suggestions for developing VR applications using the Unreal Engine 4. These suggestions include using the Android Debug Bridge (ADB) command-line tool for device control, retrieving logs and screenshots from the device, installing and uninstalling applications, starting and stopping applications, real-time log retrieval using tools like ADB and Android Device Monitor, sending console commands, diagnosing crashes, sending command line switches, and enabling logging in release versions. These tips provide valuable insights for developers who are new to developing VR applications with Unreal Engine 4.
