DOTween is one of the most commonly used animation plug-ins, which is much more convenient than using Unity's own script to write animations.

Import and setup
DOTween needs to be set up for the first use. After importing, the following window will pop up, just click the button.
Then click the green "Setup DOTween" button to set it up. The cyan button below is to generate an ASMDEF file, so that you don't have to encode the content of DOTween every time when writing the script, and improve the speed of switching after writing the code.
This window can be opened again through the menu Tools/Demigiant/DOTween Utility Panel. It is very convenient to visit the official website to view documents through here.
Click the button to display this interface, select all by default, and then select the Apply button.
