Unity excavator

This project is an achivement of my self-study on digital twin in my spare time.

Demo

WebGL-version

• Basic classical Physics
• Pneumatic Caisson
• Total station
• AGV

YouTube

• Excavator
• Pneumatic Caisson
• Pendulum
• Friction
• Solar system
• Total station
• Render Streaming

Requirements

• Unity 2019.4 LTS ... I have been upgrading some of these projects with Unity 2022.1
• Standard Assets
• Optional: Logicool Gamepad F310

Android support

I have confirmed that the project names with bold fonts run on my Google Pixel4.

Coping with this error where Standard Assets are used with Unity 2019.4

Assets\Standard Assets\Utility\SimpleActivatorMenu.cs(11,16): error CS0619: 'GUIText' is obsolete: 'GUIText has been removed. Use UI.Text instead.'

Just remove "Assets\Utility\ForcedReset.cs" and "Assets\Utility\SimpleActivatorMenu.cs".
