A conversation is the UI that allows the player to initiate up to four different talk points with an NPC, as well as present any items in the inventory to them to start a conversation. The player opens up a conversation by walking up to an NPC and pressing the spacebar key.

Presenting an item or clicking on a talk point will start a dialogue with the NPC. When that dialogue is complete, the player will be returned to the conversation UI.

The player can exit the conversation UI by hitting the backspace key.

A dialogue is the UI that shows a talking to the player. This will have the name and image of the person talking, as well as their current sentence displayed. Once the sentence has finised rendering, the player can hit the continue button to get the next sentence. Once all the sentences are displayed, the dialogue will disappear from view.

The conversation manager is responsible for displaying the correct conversation on the screen.

The dialogue manager is responsible for displaying the current dialogue on the screen.

The conversation initializer is responsible for initializing the list of conversations in the ConversationList class. It also contains a function called TriggerConversation(ActorList actor) which will go through the list of Actors to see which one triggered the function, and will pass the conversation for that actor to the ConversationManager class.

The dialogue initializer is responsible for initializing the list of dialogues in the DialogueList class. It also contains a function called TriggerDialogue(string key, bool returnToConversation) which will go through the list of Dialogues to see which one triggered the function, and will pass the conversation for that dialogue to the DialogueManager class. The returnToConversation variable dictates whether or not the converation UI will reopen upon ending the conversation.

The ConversationTrigger class sits on a game object in the player game object. It has a trigger collider on it, facing forward from the player. If it triggers with an NPC, it will store that NPC's info. If the player presses the space bar while still colliding, the conversation UI will appear. When the player trigger no longer collides with the NPC, the stored information will be erased (to prevent starting a conversation when you are not near the NPC).

For the ConversationTrigger to work correctly, it looks for a class called ActorSelector on the NPC object it collided with. The ActorSelector holds a single variable of the ActorList enum. This needs to be set in the inspector to the correct character to enable to dialogue to trigger correctly.

ActorList is an enum of defined NPCS. This list is used by the ActorSelector class to enable the gameObjects in the scene to be ID'd as the correct NPCs.

ConversationList is a static class of Conversations that can be called upon by the ConversationInitializer class. The ConversationInitializer class will look at which NPC conversation needs to be shown by comparing the NPC's ActorSelector ActorList variable, and then showing the appropriate Conversation from the ConversationList.

DialogueList is a static class of Dialogues that can be called upon by the DialogueInitializer class. The DialogueInitializer class will look at which dialogue needs to be shown by comparing the string key it was passed, and then showing the dialogue array stored as it's value pair.

The DialogueKey class is a static class of keys. These are defined for use in the DialogueList and ConversationList classes, to ensure the values are always equal. The Conversation object's array of TextBoxes has it's text value equal to a dialogue key. This is so it can be displayed to the user, and if clicked on, that key can be used to show the correct dialogue.

The inventory is a class that holds the player's current items. These can be presented to NPCs to trigger events and dialogue.

The Item Database is a static class that contains a list of all items that can be placed in the inventory.

Areas Of Interest are objects within the scene the player can interact with. They contain an item the player can pick up, and mandatory dialogue that can play. The AOI can also be destroyed after interaction.

The AreaOfInterestTrigger triggers the player's response when interacting with an area of interest. Area's of Interest need to be tagged as AreasOfInterest for the collider to detect them.
