public static method CapsuleCast(point1: Vector3, point2: Vector3, radius: float, direction: Vector3, maxDistance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): bool;
public static bool CapsuleCast(Vector3 point1, Vector3 point2, float radius, Vector3 direction, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters

point1 The center of the sphere at the start of the capsule.
point2 The center of the sphere at the end of the capsule.
radius The radius of the capsule.
direction The direction into which to sweep the capsule.
maxDistance The max length of the sweep.
layerMask A Layer mask that is used to selectively ignore colliders when casting a capsule.
queryTriggerInteraction Specifies whether this query should hit Triggers.

Returns

bool True when the capsule sweep intersects any collider, otherwise false.

Description

Casts a capsule against all colliders in the scene and returns detailed information on what was hit.

The capsule is defined by the two spheres with radius around point1 and point2, which form the two ends of the capsule. Hits are returned for the first collider which would collide against this capsule if the capsule was moved along direction. This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size, such as a character, will be able to move somewhere without colliding with anything on the way.

Notes: CapsuleCast will not detect colliders for which the capsule overlaps the collider. Passing a zero radius results in undefined output and doesn't always behave the same as Physics.Raycast.

public static method CapsuleCast(point1: Vector3, point2: Vector3, radius: float, direction: Vector3, out hitInfo: RaycastHit, maxDistance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): bool;
public static bool CapsuleCast(Vector3 point1, Vector3 point2, float radius, Vector3 direction, out RaycastHit hitInfo, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters

point1 The center of the sphere at the start of the capsule.
point2 The center of the sphere at the end of the capsule.
radius The radius of the capsule.
direction The direction into which to sweep the capsule.
maxDistance The max length of the sweep.
hitInfo If true is returned, hitInfo will contain more information about where the collider was hit. (See Also: RaycastHit).
layerMask A Layer mask that is used to selectively ignore colliders when casting a capsule.
queryTriggerInteraction Specifies whether this query should hit Triggers.
