Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 123]

DiaQ
DiaQEngine	DiaQ runtime provide the interface with the graph manager
DiaQuest	A DiaQ Quest
DiaQuestCondition	A DiaQ Quest Condition to complete. You should use the functions in DiaQuest and not interact with the condition directly, except when you want to interact with the metaData. If you change value here directly the quest might not pick up on the state change of the condition and not be able to update whether the quest is completed
DiaQuestManager	Provide access to Quest Data
DiaQuestReward	A DiaQ Quest Reward for quest completion. You should use the functions in DiaQuest and not interact with the reward directly, except when you want to interact with the metaData.
DiaQNode_Dlg	A dialogue/ conversation node. Shows text and wait for an option to be chosen. Use plyGraphManager.SendDataToNode(a_number_strating_at_0) to send a response to this node when it is waiting. So, the first response is (0), the seconds response is (1), the 3rd (2), etc.
DiaQNode_QAccept	Accept a quest
DiaQNode_QReward	Give quest rewards by running the reward givers. Not of use when reward keyStrings are used.

Int_Value	A block that creates and can return an Integer value.
plyBlox_Value	A block that creates and can return a reference to a plyBlox object.
plyValue_Block	This is the base class for Value or Variable type blocks.
plyVar_Value	A block that creates and can return a plyVar value. Reference to a plyBlox Variable.
Rect_Value	A block that creates and can return a Rect value.
SpaceEnum_Value	A block that creates and can return a UnityEngine.Space value.

UnityObject_Value	A block that creates and can return a UnityEngine.Object value.
Vector2_Value	A block that creates and can return a Vector2 value.
Vector3_Value	A block that creates and can return a Vector3 value.
plyEventTrigger	This class carry info on an Event that can be triggered and the possible params to send.
plyBlock	A plyBlock is the most basic of blocks and base class of other block types. A Block is something that is inserted into an Event and is what is executed when the Event is triggered. Have a look at plyBlockAttribute to learn more about the attribute (def.meta data) you need to include for any Block being defined. Also see plyBlockFieldAttribute for Block fields (public variables) that you define.
plyBlox	A plyBlox object is the main worker in the plyBlox Visual Scripting kit. It contains all the States, Events and Blocks that gives behaviour to an object.
plyBloxGlobal	THe plyBlox System's Global object, containing Global Variables and Blox system settings.
plyEvent	Base class for all Event definitions. An Event is part of A plyBlox' State and execute blocks when triggered. How the Event is triggered depends on what kind of Event it is. Have a look at plyEventAttribute to learn more about the Attribute (def.meta data) you need to include for any Event you define.
plyEventHandler	Base class for all Event handlers. When defining new Events you also need to define a handler, or handlers, for those events. The Event.HandlerType override is used to specify that this Handler can handle that specific Event. Handlers can obviously handle more than one Event type and is recommended where possible. Since a handler is simply a MonoBehaviour, or Component, it will be added to the GameObject that has an Event, in its plyBlox, that needs to be handled. So you can assume that anything that works in a Behavior will work in the Event Handler, like Update, OnTriggerEnter, etc.
plyState	plyBlox can be in one of several states. The designer will use the plyBlox Editor to add States to a blox object. Each state can have several Events that can be triggered. Events execute Blocks when triggered. You should to normally have to deal with this class directly.
plyVar	A plyBlox variable. plyBlox has 3 types of variables. Global, which is accessible from anywhere via plyBloxGlobal and belongs to the game project. Local, which belongs to a Blox object. Temporary, which is only valid within an Event and that Event only
plyBloxKitEditor
plyBlockFieldHandler	A field handler is needed when you created custom types to use as fields in blocks. The handler will know how to make a copy of the field type and how to render it in the editor.

plyDataObject	Retrieve and present values at run-time. Has own fields that user uses to specify where data comes from. Can also be used as a way to specify callback.
plyDataProviderInterface	Those classes able to provide plyDataObject with data must implement this interface It can also be used where a general callback is needed and the data set/ get might be ignored by a system
plyInlineValue	A value that can be inserted into text at run-time. For example "Hello {Name}" would be used to insert the value from an inline value called "name" into the string via the ProcessText() function.

IntScale	Simple int based width and height.
plyCondition	A class that can compare values/ variables
plyCurve	A curve or 2D graph represented by an array of values. The array index represents the horizontal (X) and the value of each represents the vertical (Y) of the graph.
plyExtensions	Various extensions.
plyMetaData	A class that can hold a value from a variety of types
plyMetaDataInterface	Classes that makes use of metaData can implement this interface to make it easier for other systems to gain access to the metaData entries.
