Getting started with Unity3D

Drag shortcut

First look at the Scene interface, where we basically complete the layout of the game objects in the game scene

• Press and hold the mouse wheel key: the plane can be dragged without moving the object
• Press and hold the right mouse button: we can rotate the viewing angle of our observation interface without moving the object; at the same time, we can use wasd to move
• Left mouse button: operation object (toolbar on the left side of the Scene interface)
  • The first View Tool: Drag and drop the plane, similar to holding down the scroll wheel with a mouse
  • The second Move Tool: move the position of the object
  • The third Rotate Tool: rotate the object
  • The fourth Scale Tool: scaling objects
  • The fifth Rect Tool: equivalent to the two-dimensional Scale Tool
  • The sixth Transform Tool: equivalent to the above four sets

resource store

When you need any resources you lack, and you can't draw or build these resources by yourself, you can consider using existing resources to realize that the unity resource store can almost meet your basic needs for
learning unity3D

Just select the required resources and put them in My Resources, click Window on the upper toolbar in Unity, and select Package Management again to
find My Assets, and select the corresponding resource Download&Import
