Level Select

Menu Buttons

Uses the player's raycast object to click a button. When a button is clicked, the respective Load<"Scene">Async() function will be run.

Functionality

Every Load<"Scene">Async() function will set a string variable located in the UserManager called "nextSceneToLoad", then loads the "Loading scene".

• Example For Loading Office Scene

1. When a button is clicked to load the "Office", the function LoadOfficeAsync() is executed
2. The variable, "nextSceneToLoad", in the UserManager is set to "Office"
3. The Scene is switched to the "Loading scene"
4. The variable "nextSceneToLoad" is passed to the LoadSceneAsync() function and the Office scene begins to load asynchronously
