Declaration

public static RaycastHit2D CapsuleCast(Vector2 origin, Vector2 size, CapsuleDirection2D capsuleDirection, float angle, Vector2 direction, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, float minDepth = -Mathf.Infinity, float maxDepth = Mathf.Infinity);

Parameters

origin The point in 2D space where the capsule originates.
size The size of the capsule.
capsuleDirection The direction of the capsule.
angle The angle of the capsule (in degrees).
direction Vector representing the direction to cast the capsule.
distance The maximum distance over which to cast the capsule.
layerMask Filter to detect Colliders only on certain layers.
minDepth Only include objects with a Z coordinate (depth) greater than this value.
maxDepth Only include objects with a Z coordinate (depth) less than this value.

Returns

RaycastHit2D The cast results returned.

Description

Casts a capsule against Colliders in the Scene, returning the first Collider to contact with it.

A CapsuleCast is conceptually like dragging a capsule through the Scene in a particular direction. Any object making contact with the capsule can be detected and reported.

This function returns a RaycastHit2D object with a reference to the Collider that is hit by the capsule (the Collider property of the result will be NULL if nothing was hit). The layerMask can be used to detect objects selectively only on certain layers (this allows you to apply the detection only to enemy characters, for example).

The returned RaycastHit2D returns both the point and normal of the contact where the capsule would touch the Collider. It also returns the centroid where the capsule would be positioned for it to contact at that point.

Declaration

public static int CapsuleCast(Vector2 origin, Vector2 size, CapsuleDirection2D capsuleDirection, float angle, Vector2 direction, ContactFilter2D contactFilter, RaycastHit2D[] results, float distance = Mathf.Infinity);

Parameters

origin The point in 2D space where the capsule originates.
size The size of the capsule.
capsuleDirection The direction of the capsule.
angle The angle of the capsule (in degrees).
direction Vector representing the direction to cast the capsule.
contactFilter The contact filter used to filter the results differently, such as by layer mask, Z depth, or normal angle.
results The array to receive results. The size of the array determines the maximum number of results that can be returned.
distance The maximum distance over which to cast the capsule.

Returns

int Returns the number of results placed in the results array.

Description

Casts a capsule against the Colliders in the Scene and returns all Colliders that are in contact with it.

A CapsuleCast is conceptually like dragging a capsule through the Scene in a particular direction. Any object making contact with the capsule can be detected and reported.

This function returns the number of contacts found and places those contacts in the results array. The results can also be filtered by the contactFilter.

Declaration

public static int CapsuleCast(Vector2 origin, Vector2 size, CapsuleDirection2D capsuleDirection, float angle, Vector2 direction, ContactFilter2D contactFilter, List<RaycastHit2D> results, float distance = Mathf.Infinity);

Parameters

origin The point in 2D space where the capsule originates.
size The size of the capsule.
capsuleDirection The direction of the capsule.
angle The angle of the capsule (in degrees).
direction A vector representing the direction to cast the capsule.
contactFilter The contact filter used to filter the results differently, such as by layer mask, Z depth, or normal angle.
results The list to receive results.
distance The maximum distance over which to cast the capsule.

Returns

int Returns the number of results placed in the results list.

Description

Casts a capsule against the Colliders in the Scene and returns all Colliders that are in contact with it.

A CapsuleCast is conceptually like dragging a capsule through the Scene in a particular direction. Any Collider making contact with the capsule can be detected and reported.

The integer return value is the number of results written into the results list. The results list will be resized if it doesn't contain enough elements to report all the results. This prevents memory from being allocated for results when the results list does not need to be resized, and improves garbage collection performance when the query is performed frequently.

The results can also be filtered by the contactFilter.
