VR interactive game design based on unity3d engine

In order to enable users to get an immersive experience in the game environment, a VR interactive game design method based on Unity3D engine is proposed. According to the VR game design process and the interactive methods in the game, analyze the VR interactive game design concept, according to the data structure of the VR interactive game, combined with the state space search method to traverse, use the gravity acceleration component of the multi-axis acceleration sensor to calculate the pitch of the VR device Angle, according to the user's pitch angle, acceleration and gravity sensing information, real-time positioning of the user's head movement, controlling the position of the VR device in the game engine, and optimizing the rendering result of the VR game space structure, completing the Unity3D engine-based VR interactive game design. The experimental results show that the experience satisfaction of the VR interactive game design is higher than that of the traditional VR interactive game design, and it fulfills the requirements of obtaining an immersive experience in a virtual reality game environment.
