Namespace: GUPS.AntiCheat.Protected

Assembly: cs.temp.dll.dll

Syntax

public struct ProtectedDouble

Constructors

ProtectedDouble(Double)

Initializes a new protected double with the specified value.

Declaration

public ProtectedDouble(double value = 0)

Parameters

Type	Name	Description
System.Double	value	Initial value.

Properties

HasIntegrity

Gets a value indicating whether the protected value still has integrity (i.e. the honeypot has not been tampered with).

Declaration

public bool HasIntegrity { get; }

Property Value

Type	Description
System.Boolean

Value

Gets or sets the unobfuscated value.

Declaration

public double Value { get; set; }

Property Value

Type	Description
System.Double

Remarks

Reading the value runs an integrity check; if the honeypot has been tampered with, the is notified.

Methods

CheckIntegrity()

Returns true when the honeypot still matches the obfuscated value.

Declaration

public bool CheckIntegrity()

Returns

Type	Description
System.Boolean	true if the value is intact; otherwise false.

Dispose()

Clears the obfuscated value, scratch union and secret.

Declaration

public void Dispose()

Equals(Object)

Returns true when this protected value equals the given object.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
System.Object	obj	Object to compare with.

Returns

Type	Description
System.Boolean	true if equal; otherwise false.

Overrides

System.ValueType.Equals(System.Object)

GetHashCode()

Returns the hash code of the obfuscated bit pattern.

Declaration

public override int GetHashCode()

Returns

Type	Description
System.Int32	Hash code based on the stored obfuscated bits (does not unobfuscate).

Overrides

System.ValueType.GetHashCode()

Obfuscate()

Rerolls the secret and re-obfuscates the current value.

Declaration

public void Obfuscate()

OnAfterDeserialize()

Unity deserialization hook; rebuilds the obfuscation state from the deserialized honeypot value.

Declaration

public void OnAfterDeserialize()

OnBeforeSerialize()

Unity serialization hook; writes the true value into the honeypot field.

Declaration

public void OnBeforeSerialize()

ToString()

Returns the string representation of the unobfuscated value.

Declaration

public override string ToString()

Returns

Type	Description
System.String	The string representation of the unobfuscated value.

Overrides

System.ValueType.ToString()

Operators
