Dialogue Bubble

This component is similar to Dialogue, an interactive dialogue system, but instead uses speech bubbles within world space to display conversations between the player and NPC.

To set up the system, a minimum of two components are required: DialogueBubble, which stores the dialogue between the characters, and Bubble, which manages the UI elements that will display the dialogue. The DialogueBubble component can be placed on a relevant or empty game object, while each player and NPC should have an individual Bubble game object set as a child. These game objects should be deactivated; the system will be in charge of activating them.

Property
Exit Button	If this button exists, the user will be able to escape any dialogue.
Skip Button	If this button exists, the user will be able to skip to the next message in the conversation at any time.
Block Inventories	If enabled, any inventory trying to open will be blocked from opening.
Block Player Input	If enabled, when dialogue is started, the player input will be automatically blocked.
Fade In, Fade Out Times	This will dictate how fast the speech bubbles appear and disappear when they are active.
Events	The Unity Events invoked when the player begins and exits a conversation.

Method
BeginConversation()	Call this method to begin the conversation. This will also set this gameObject active true.
EndConversation()	Call this method to end the conversation.

Create any messenger that is relevant to the dialogue.

Property
Messenger Bar	Choose the messenger’s sprite icon and display name. From here, delete this messenger if necessary, and toggle the box open for more fields.
Bubble	Set the Bubble reference that belongs to this messenger.
Choice	If this messenger needs to pick between multiple choices, set the reference for each Bubble that will act as a choice bubble.

A dialogue is a series of conversations. Add as many as required. Each conversation will have a series of messages. Each message can either be of type Message or Choice. If Choice type is enabled, it should be the last message in the conversation because the player will be asked to make a choice, and each option in the choice will branch into another conversation. The dialogue will end once the current conversation reaches the final message that is of type Message.

Property
Conversation Bar	This displays the name of the conversation. From here, delete the conversation if necessary, add a new message, or open the box for more fields.
Message Bar	This displays the messenger’s icon. Choose which messenger is talking and the type of message.
Message To	If the speech bubbles are directional, specify who the message is being delivered to so the system can know how to flip the speech bubble.
On Message Complete	The Unity Event invoked after the message is finished loading.
Message Type	If enabled, a standard message will be displayed. Type the desired message in the text box.
Choice Type	If enabled, press the add button to create a series of options for the player to choose from. Each option will have a white button on the left; toggle this button for extra settings and to choose which conversation to branch to.

Note

When dialogue is started, the first conversation in the list will be the entry point.

Bubble

The Bubble component displays the text and changes the size of the UI image, typically the speech bubble, to fit around the text. Thus this component should exist on a Canvas gameObject that is a child of the messenger (player or NPC). If a TextMeshProEffects component exists, it will use the typewriting effect to type the text on the screen.

If the player has to make choices, then a separate speech bubble should be created for each choice required. These speech bubbles should then be referenced in the DialogueBubble component.

Place the speech bubble exactly where you want it to appear in the y direction. The system will override the x position. Please refer to the tidbit scene for an example of speech bubbles.

References
Text Mesh	The reference to the textMeshPro used for displaying text.
Image	The reference to the speech bubble image.
Is Directional	If enabled, the speech bubble will be flipped to face the other messenger.
Size	Set the minimum and maximum size the speech bubble can ever be changed to.
Padding	The space between the text and the border of the speech bubble.
Text Offset Y	The displacement of the text in the y direction.
Bubble Offset X	The displacement between the messenger and the speech bubble in the x direction.
Events	The Unity Events invoked when the speech bubble transitions in and transitions out into the scene, and when it loads its text.
