UE4_動態代理FScriptDelegate 執行ProcessDelegate 函數崩潰

原因：

void ADecActor::RunUFunOne()
{
	FScriptDelegate FunDelOne;
	FunDelOne.BindUFunction(SrcObj, FName("UFunOne"));
	if (FunDelOne.IsBound())
	{
		FunDelOne.ProcessDelegate<UObject>(SrcObj);
	}


}

乍看這段代碼是沒有問題的，可是IsBound() 函數返回的是false，意思就是沒有通過安全認證。可以手動查看源碼，截碼如下：

        // Object was pending kill, so we cannot execute the delegate.  Note that it's important to assert
		// here and not simply continue execution, as memory may be left uninitialized if the delegate is
		// not able to execute, resulting in much harder-to-detect code errors.  Users should always make
		// sure IsBound() returns true before calling ProcessDelegate()
		UObjectTemplate* ObjectPtr = static_cast< UObjectTemplate* >( Object.Get() );	// Down-cast
		checkSlow( !ObjectPtr->IsPendingKill() );

		// Object *must* implement the specified function
		UFunction* Function = ObjectPtr->FindFunctionChecked( FunctionName );

		// Execute the delegate!
		ObjectPtr->ProcessEvent(Function, Parameters);

解決辦法如下：
在需要綁定到代理上的函數加上***UFUNCTION()*** 這個宏就可以了。
