타일맵 콜라이더 2D

The Tilemap Collider 2D component generates Collider shapes for Tiles on a Tilemap component on the same GameObject. When you add or remove Tiles on the Tilemap component, the Tilemap Collider 2D updates the Collider shapes during LateUpdate. It batches multiple Tile changes together to ensure minimal impact on performance.

Tilemap Collider 2D 프로퍼티

프로퍼티	기능
Max Tile Change Count	Set the maximum number of Tile changes (such as adding/removing Tiles to the Tilemap) to accumulate before doing a full Collider rebuild instead of an incremental rebuild. Note: A high number of accumulated changes can cause the incremental rebuild of the Tilemap Collider 2D to be slower than a full rebuild. Decrease this value to resolve this issue.
Extrusion Factor	Set the amount (in Unity world space units) to extrude the Collider shape of each Tile. This minimizes the gaps between the Collider shapes of neighboring Tiles and brings them to within the minimum Vertex Distance set in the Composite Collider 2D, which can then compose the Tile Colliders together. Note: This property isn’t available by default. It becomes available when you enable Used by Composite, and attach a Composite Collider 2D to the same GameObject.
Material	Select the Physics Material 2D that determines properties of collisions, such as friction and bounce.
Is Trigger	Enable this if you want this Collider 2D to behave as a trigger. The physics system ignores this Collider when this is enabled.
Used by Effector	Enable this if you want the Collider 2D to be used by an attached Effector 2D.
Used by Composite	Enable this to use this Collider with an attached Composite Collider 2D. When you enable Used by Composite, all properties except Offset will no longer be available in the Tilemap Collider 2D component and the attached Composite Collider 2D component controls the Collider properties instead.
Offset	콜라이더 2D 지오메트리의 로컬 오프셋 값을 설정합니다.
Layer Overrides	Expand for the Layer override settings.
	Layer Override Priority	Assign the decision priority that this Collider2D uses when resolving conflicting decisions on whether a contact between itself and another Collision2D should happen or not. Refer to its API page for more information.
	Include Layers	Select the additional Layers that this Collider 2D should include when deciding if a contact with another Collider2D should happen or not. Refer to its API documentation for more information.
	Exclude Layers	Select the additional Layers that this Collider 2D should exclude when deciding if a contact with another Collider2D should happen or not. Refer to its API documentation for more information.
	Force Send Layers	Select the Layers that this Collider 2D is allowed to send forces to during a Collision contact with another Collider2D. Refer to its API documentation for more information.
	Force Receive Layers	Select the Layers that this Collider 2D can receive forces from during a Collision contact with another Collider2D. Refer to its API documentation for more information.
	Contract Capture Layers	Select the Layers of other Collider 2D, involved in contacts with this Collider2D, that will be captured. Refer to its API documentation for more information.
	Callback Layers	Select the Layers that this Collider 2D, during a contact with another Collider2D, will report collision or trigger callbacks for. Refer to its API documentation for more information.

Collider Type’s effect on Collider generation

The Collider shapes generated for each Tile in the Tilemap depend on the desired Collider type set in the Tile Asset’s properties. The component’s shape generation behavior corresponds to the Collider Types in the following ways:

콜라이더 타입	기능
없음	Tilemap Collider 2D 컴포넌트는 이 타일에 대한 콜라이더 모양을 생성하지 않습니다.
Sprite	The Tilemap Collider 2D component generates a Collider shape based on the Sprite assigned to the Tile. The Collider shape is based on the Custom Physics Shape set for the Sprite.
Grid	Tilemap Collider 2D 컴포넌트는 선택한 Grid 컴포넌트의 셀 레이아웃에 의해 결정되는 그리드 셀의 모양에 기반하여 콜라이더 모양을 생성합니다.

타일맵 및 합성 콜라이더

You can use the Tilemap Collider 2D component together with the Composite Collider 2D component. When you add both components to the same Tilemap, Unity composites the Collider shapes of neighboring Tiles together. This smoothens the corners and edges between Collider shapes in neighboring Tiles.

두 컴포넌트를 함께 사용하면 물리 업데이트에 필요한 개별 콜라이더 모양 수가 감소하므로 필요한 계산량이 줄어들고 성능에 미치는 영향이 최소화됩니다.

스크립팅 API 팁

If you require immediate changes to happen to the Collider, use Tilemaps.TilemapCollider2D.ProcessTilemapChanges to process them immediately. You can use Tilemaps.TilemapCollider2D-hasTilemapChanges to check if any processing is required.
