+	\subsection{Delegates}
+	Delegates allow to call variable functions via a type-safe way.
+	There are 3 big types of delegates:
+	\begin{itemize}
+		\item Single-cast Delegates, which can have a single function target, declared with \verb|DECLARE_DELEGATE_|
+		\item Multi-cast Delegates, which can have multiple function targets, declared with \verb|DECLARE_MULTICAST_DELEGATE_|
+		\item Dynamic Multicasts, which can be serialized, and functions can be found by name, declared with \verb|DECLARE_DYNAMIC_DELEGATE_| or \verb|DECLARE_DYNAMIC_MULTICAST_DELEGATE_|
+	\end{itemize}
+	All Delegate macros have the syntax: \linebreak \verb|_DELEGATE_<Num>Params(Name,Param1Type,Param2Type,...)|
+	or for functions with return value: \linebreak
+	\verb|DECLARE_DELEGATE_RetVal(RetValType, Name)|
+	
+	Code example:
+	
+	\begin{verbatim}
+	DECLARE_MULTICAST_DELEGATE(VoidDelegate)
+	DECLARE_DELEGATE_OneParam(IntParamDelegate, int32)
+	DECLARE_DELEGATE_TwoParams(MyDelegate, int32, AActor*)
+	DECLARE_DELEGATE_RetVal_OneParam(int, Delegate2, uint8)
+	void MyFunc;
+	void MyFunc2(int32);
+	VoidDelegate Del1;
+	//Somewhere in func body
+	Del1.Add(this, FName("MyFunc")); //Add MyFunc
+	Del1.Broadcast(); //Call all bound functions
+	IntParamDelegate Del2;
+	Del2.Add(this, FName("MyFunc2)); //Bind MyFunc2
+	Del2.ExecuteIfBound(10); //Call MyFunc2
