Welcome to the Standard (Built-in Engine) version of SMARC Unity. This project has all of the dependencies configured and installed in order to showcase the SMARC Unity Assets package with minimal effort.
If you have not used unity before I suggest trying out a few tutorials from https://learn.unity.com/
To get started, I suggest you familiarize yourself with the editor from: https://learn.unity.com/tutorial/explore-the-unity-editor-1#
If you want to jump in quickly to see the sim, follow the next few steps.
- In the Project Window (tab at the bottom) open: Scenes/WaterSimulation.Unity
- In the central panel, click on Scene. This is the "Editor" window. The "Game" window is simply a camera that has been set up into the scene.
- In the Hierarchy (panel on the left side), double click on SAM to pan to it.
- Click the Play button
From here you should be able to move SAM around using the arrow keys and WASD. You might want to drag and drop the Game window (you can split the view), so you can see both the Scene and Game windows in parallel.
