Box Collider 2D

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

プロパティ 機能
Material 摩擦や弾性など衝突の種類を定義する Physics マテリアル。
Is Trigger このボックスをチェックすると、Box Collider 2D はトリガーになります。
Used by Effector このボックスをチェックすると、Box Collider 2D はアタッチした Effector 2D コンポーネントによって使用されます。
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 Collider 2D ジオメトリのローカルのオフセットを設定します。
Size ローカル空間でのボックスのサイズを設定します。
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).
