설명

Parent class for collider types used with 2D gameplay.

변수

attachedRigidbodyThe Rigidbody2D attached to the Collider2D.
bouncinessGet the bounciness used by the collider.
boundsThe world space bounding area of the collider.
compositeGet the CompositeCollider2D that is available to be attached to the collider.
densityThe density of the collider used to calculate its mass (when auto mass is enabled).
errorStateThe error state that indicates the state of the physics shapes the 2D Collider tried to create. (Read Only)
frictionGet the friction used by the collider.
isTriggerIs this collider configured as a trigger?
offsetThe local offset of the collider geometry.
shapeCountThe number of active PhysicsShape2D the Collider2D is currently using.
sharedMaterialThe PhysicsMaterial2D that is applied to this collider.
usedByCompositeSets whether the Collider will be used or not used by a CompositeCollider2D.
usedByEffectorWhether the collider is used by an attached effector or not.

Public 함수

CastCasts the Collider shape into the Scene starting at the Collider position ignoring the Collider itself.
ClosestPointReturns a point on the perimeter of this Collider that is closest to the specified position.
CreateMeshCreates a planar Mesh that is identical to the area defined by the Collider2D geometry.
DistanceCalculates the minimum separation of this collider against another collider.
GetContactsRetrieves all contact points for this Collider.
GetShapeHashGenerates a simple hash value based upon the geometry of the Collider2D.
GetShapesGets all the PhysicsShape2D used by the Collider2D.
IsTouchingCheck whether this collider is touching the collider or not.
IsTouchingLayersChecks whether this collider is touching any colliders on the specified layerMask or not.
OverlapColliderGet a list of all colliders that overlap this collider.
OverlapPointCheck if a collider overlaps a point in space.
RaycastCasts a ray into the Scene that starts at the Collider position and ignores the Collider itself.

메시지

OnCollisionEnter2DSent when an incoming collider makes contact with this object's collider (2D physics only).
OnCollisionExit2DSent when a collider on another object stops touching this object's collider (2D physics only).
OnCollisionStay2DSent each frame where a collider on another object is touching this object's collider (2D physics only).
OnTriggerEnter2DSent when another object enters a trigger collider attached to this object (2D physics only).
OnTriggerExit2DSent when another object leaves a trigger collider attached to this object (2D physics only).
OnTriggerStay2DSent each frame where another object is within a trigger collider attached to this object (2D physics only).
