    Syntax
    public struct ColliderKey : IEquatable<ColliderKey>, IComparable<ColliderKey>

    Constructors

    ColliderKey(UInt32, UInt32)

    Constructor.

    Declaration
    public ColliderKey(uint numSubKeyBits, uint subKey)
    Parameters
    Type Name Description
    UInt32 numSubKeyBits

    Number of sub key bits.

    UInt32 subKey

    The sub key.

    Fields

    Empty

    Empty collider key.

    Declaration
    public static readonly ColliderKey Empty
    Field Value
    Type Description
    ColliderKey

    Properties

    Value

    Gets or sets the value.

    Declaration
    public uint Value { get; }
    Property Value
    Type Description
    UInt32

    The value.

    Methods

    CompareTo(ColliderKey)

    Compares this ColliderKey object to another to determine their relative ordering.

    Declaration
    public int CompareTo(ColliderKey other)
    Parameters
    Type Name Description
    ColliderKey other

    Another instance to compare.

    Returns
    Type Description
    Int32

    Negative if this object is less than the other, 0 if they are equal, or positive if this is greater.

    Implements
    IComparable<T>.CompareTo(T)

    Equals(ColliderKey)

    Tests if this ColliderKey is considered equal to another.

    Declaration
    public bool Equals(ColliderKey other)
    Parameters
    Type Name Description
    ColliderKey other

    The collider key to compare to this object.

    Returns
    Type Description
    Boolean

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

    Implements
    IEquatable<T>.Equals(T)

    PopSubKey(UInt32, out UInt32)

    Extract a sub key from the front of the path. "numSubKeyBits" is the maximum number of bits required to store any value for this sub key. Returns false if the key is empty.

    Declaration
    public bool PopSubKey(uint numSubKeyBits, out uint subKey)
    Parameters
    Type Name Description
    UInt32 numSubKeyBits

    Number of sub key bits.

    UInt32 subKey

    [out] The sub key.

    Returns
    Type Description
    Boolean

    False if the key is empty, true otherwise.

    PushSubKey(UInt32, UInt32)

    Append a sub key to the front of the path "numSubKeyBits" is the maximum number of bits required to store any value for this sub key.

    Declaration
    public void PushSubKey(uint numSubKeyBits, uint subKey)
    Parameters
    Type Name Description
    UInt32 numSubKeyBits

    Number of sub key bits.

    UInt32 subKey

    The sub key.

    ToString()

    Convert this object into a string representation.

    Declaration
    public override string ToString()
    Returns
    Type Description
    String

    A string that represents this object.

    Overrides
    ValueType.ToString()

    Operators

    Implicit(UInt32 to ColliderKey)

    Implicit cast that converts the given uint to a ColliderKey.

    Declaration
    public static implicit operator ColliderKey(uint key)
    Parameters
    Type Name Description
    UInt32 key

    The key.

    Returns
    Type Description
    ColliderKey

    The result of the operation.

    Implicit(ColliderKey to UInt32)

    Implicit cast that converts the given ColliderKey to an uint.

    Declaration
    public static implicit operator uint (ColliderKey key)
    Parameters
    Type Name Description
    ColliderKey key

    The key.

    Returns
    Type Description
    UInt32

    The result of the operation.
