AI-generated summary

The document outlines the implementation of an asynchronous scene transition with a progress bar using a Slider UI component in Unity. It involves three scenes: Menu, Loading, and VRsubway. The SceneManager.LoadSceneAsync method is used for asynchronous loading, while the AsyncOperation class tracks the loading progress displayed by the Slider component. A Loading script is created to manage the process, but the author notes that the loading experience is not smooth and seeks further optimization tips.

Asynchronous Scene Switching with Progress Bar#

Working on it, I want to implement a scene switching feature with a progress bar: here we use the UI component Slider to complete it

Specific Implementation:#

Three scenes are needed: 【Menu】——【Loading】——【VRsubway】
The SceneManager.LoadSceneAsync method can achieve asynchronous loading, meaning the current scene remains unchanged during loading.
Use the AsyncOperation class to get the loading progress.
Use the Slider component to display the progress.

Simple Setup for the 【Loading】 Scene#

Summary#

I don't fully understand this yet; the functionality seems to be implemented, but the effect may not be very satisfactory. There is a stutter during loading, and I can't figure out the reason for it at the moment. I will explain it later when I learn optimization methods. Any guidance is welcome!!!
