Dialogues

The Crafty component that adds an entity a ability to carry conversation. As data source it uses JSON file. For building data source structure you can use prepared Dialogues builder tool.

###Type of dialogues:

• Linear
• Linear interrupted
• Linear dialogue with questions
• Branched dialogue with different results
• Fake branched dialogue with the same end
• Procedural dialogue
• Combined dialogue

###Advantage:

• no depending on the third party library
• documented code
• tested code

###Usage: Set source data to entity.

Crafty.e("2D, DOM, Dialogues").setDialogues( DIALOGUES_DATA_SOURCE );   

Make sure that there is a container for dialogs. Default container for views is #chat, but you can change it.

<div id="chat"></div>

Show dialogue

Crafty.e("2D, DOM, Dialogues").showDialogue();   

At the end of conversation you can catch a ConversationIsOver event.

Crafty.e("2D, DOM, Dialogues")
.bind("ConversationIsOver", function(){          	        	
	this.endOfConversation();
}); 

Helper method

Close the conversation

Crafty.e("2D, DOM, Dialogues").endOfConversation();   

Clear chat container

Crafty.e("2D, DOM, Dialogues").emptyChatContainer();   

Get actual dialogue

Crafty.e("2D, DOM, Dialogues").getDialogue();   

Find dialogue by id

Crafty.e("2D, DOM, Dialogues").findDialogueById(id);   

Root of dialogues

Crafty.e("2D, DOM, Dialogues").getRoot();   

Get actor

Crafty.e("2D, DOM, Dialogues").getActor( id );

"codeAfter": "this.getDialogue().passThrough=true",

Evaluate the condition on the current dialogue

"conditionsString": "this.getDialogue().passThrough==true",

Execute code on "this" scope of the entity with Dialogues component

"codeBefore": "this.experience = 1000",

Execute code on an remote entity

"codeBefore": "Crafty("RemoteEntityName").isReady = true",
