transform

Not only controls the rotation, position, and scaling of components, but also controls the parent-child relationship between components

video player

It’s not difficult to make a function of watching TV in the game. Let’s talk about the
plane model used for the screen, and paste it directly in front of the TV.
The video can be directly placed on the video player component on the plane, and the script is also hung on the plane.
