Box Collider 2D (Прямоугольный коллайдер)

The Box Collider 2D component is a Collider for use with 2D physics. Its shape is a rectangle with a defined position, width and height in the local coordinate space of a Sprite. Note that the rectangle is axis-aligned - that is, its edges are parallel to the X or Y axes of local space.

Property Function
Material Физический материал, который определяет свойства столкновений, такие как трение и отскок.
Is Trigger Является ли коллайдер триггером?
Used by Effector Check this box if you want the Box Collider 2D to be used by an attached Effector 2D component.
Used by Composite Tick this checkbox if you want this Collider to be used by an attached Composite Collider 2D.

When you enable Used by Composite, other properties disappear from the Box Collider 2D component, because they are now controlled by the attached Composite Collider 2D. The properties that disappear from the Box Collider 2D are Material, Is Trigger, Used By Effector, and Edge Radius.
Auto Tiling Tick this checkbox if the Sprite Renderer component for the selected Sprite has the Draw Mode set to Tiled. This enables automatic updates to the shape of the Collider 2D, meaning that the shape is automatically readjusted when the Sprite’s dimensions change. If you don’t enable Auto Tiling, the Collider 2D geometry doesn’t automatically repeat.
Offset Set the local offset of the Collider 2D geometry.
Size Ширина и высота прямоугольника в единицах местного пространства.
Edge Radius Controls a radius around edges, so that vertices are circular. This results in a larger Collider 2D with rounded convex corners. The default value for this setting is 0 (no radius).
