Syntax

public struct CollisionFilter : IEquatable<CollisionFilter>

Fields

BelongsTo

A bit mask describing which layers this object belongs to.

Declaration

public uint BelongsTo

Field Value

Type	Description
uint

CollidesWith

A bit mask describing which layers this object can collide with.

Declaration

public uint CollidesWith

Field Value

Type	Description
uint

Default

(Immutable) A collision filter which wants to collide with everything.

Declaration

public static readonly CollisionFilter Default

Field Value

Type	Description
CollisionFilter

GroupIndex

An optional override for the bit mask checks. If the value in both objects is equal and positive, the objects always collide. If the value in both objects is equal and negative, the objects never collide.

Declaration

public int GroupIndex

Field Value

Type	Description
int

Zero

(Immutable) A collision filter which never collides with against anything (including Default).

Declaration

public static readonly CollisionFilter Zero

Field Value

Type	Description
CollisionFilter

Properties

IsEmpty

Returns true if the filter cannot collide with anything, which likely means it was default constructed but not initialized.

Declaration

public bool IsEmpty { get; }

Property Value

Type	Description
bool	True if this object is empty, false if not.

Methods

CreateUnion(CollisionFilter, CollisionFilter)

Return a union of two filters.

Declaration

public static CollisionFilter CreateUnion(CollisionFilter filterA, CollisionFilter filterB)

Parameters

Type	Name	Description
CollisionFilter	filterA	The filter a.
CollisionFilter	filterB	The filter b.

Returns

Type	Description
CollisionFilter	The new union.

Equals(CollisionFilter)

Tests if this CollisionFilter is considered equal to another.

Declaration

public bool Equals(CollisionFilter other)

Parameters

Type	Name	Description
CollisionFilter	other	The collision filter to compare to this object.

Returns

Type	Description
bool	True if the objects are considered equal, false if they are not.

GetHashCode()

Calculates a hash code for this object.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	A hash code for this object.

Overrides

ValueType.GetHashCode()

IsCollisionEnabled(CollisionFilter, CollisionFilter)

Return true if the given pair of filters want to collide with each other.

Declaration

public static bool IsCollisionEnabled(CollisionFilter filterA, CollisionFilter filterB)

Parameters

Type	Name	Description
CollisionFilter	filterA	The filter a.
CollisionFilter	filterB	The filter b.

Returns

Type	Description
bool	True if the collision is enabled, false if not.
