"Unity notes" traps for static collisions

Concept

Static Collider: objects are checked for static statics, with Collider components and no rigidbody components.

The trap of the static collision body

When the game is initialized, unity merges all the static collisions into a large collider,unity that the objects cannot be moved in the game. But if you accidentally move the positions of these static collisions (which can be moved) in the game, it can cause a serious performance problem, and all the other static collisions that merge with the moved Static collider are recalculated.

So in the game do not move the static collision body, disable disabled, turn on enabled, change the zoom scale and other operations.
