JSON Branch Dialogue Example

Preview:

Dialog File

using Array editor / Excel to prepare dialogue data.

The same ID will be considered the continuous conversation.

ID Name Text
Screen1_Intro Alice Hi, Bob! How are you today?
Screen1_Intro Bob I'm ok, tdank you, Alice. How about you?
Screen1_Intro Alice Perfect!

If the dialog has options, use Choice1-Text and Choice1-Next to mark them.

ID Name Text Choice1-Text Choice2-Text Choice1-Next Choice2-Next
Screen1_Fruit Alice I was just wondering, do you like apples or oranges better? Apples Oranges Screen1_Apples Screen1_Oranges
Screen1_Apples Bob I love apples! Tdey're my favorite fruit.
Screen1_Oranges Bob Oranges are great too, especially for a refreshing snack.

Dialog Parse

Next, the Array File will be processed into a JSON format.The same ID will merged into an array.

  • JSON
    	[
    		   {
    		       "ID": "Screen1_Intro",
    		       "Name": "Alice",
    		       "Text": "Hi, Bob! How are you today?"
    		   },
    		   {
    		       "ID": "Screen1_Intro",
    		       "Name": "Bob",
    		       "Text": "I'm ok, thank you, Alice. How about you?"
    		   },
    		   {
    		       "ID": "Screen1_Intro",
    		       "Name": "Alice",
    		       "Text": "Perfect!"
    		   }
    	]
    	
  • Array.json file

    Do you know? In fact, the C3 Array file has such a data structure inside it, so we can convert it.

    		{
    		  "c2array": true,
    		  "size": [7, 9, 1],
    		  "data": [
    		    [["ID"], ["Screen1_Intro"], ["Screen1_Intro"], ["Screen1_Intro"], ["Screen1_Fruit"], ["Screen1_Apples"], ["Screen1_Oranges"], [""], [""]],
    		    [["Name"], ["Alice"], ["Bob"], ["Alice"], ["Alice"], ["Bob"], ["Bob"], [""], [""]],
    		    [["Text"], ["Hi, Bob! How are you today?"], ["I'm ok, thank you, Alice. How about you?"],["Perfect!"], ["I was just wondering,  do you like apples or oranges better?"], ["I love apples! They're my favorite fruit."], ["Oranges are great too,  especially for a refreshing snack."],[""],[""]],
    		    [["Choice1-Text"], [""], [""], [""], ["Apples"], [""], [""], [""], [""]],
    		    [["Choice2-Text"], [""], [""], [""], ["Oranges"], [""], [""], [""], [""]],
    		    [["Choice1-Next"], [""], [""], [""], ["Screen1_Apples"], [""], [""], [""], [""]],
    		    [["Choice2-Next"], [""], [""], [""], ["Screen1_Oranges"], [""], [""], [""], [""]]
    		  ]
    		}
    		
  • Javascript Code
    		const c3ArrayFile = JSON.parse(localVars.source);
    		let result = {};
    		
    		for (let i = 1; i < c3ArrayFile.data[0].length; i++) {
    				  let id = c3ArrayFile.data[0][i][0];
    				  if (id && !result[id]) {
    				      result[id] = [];
    				  }
    		
    				  let obj = {};
    				  for (let j = 0; j < c3ArrayFile.data.length; j++) {
    				      let key = c3ArrayFile.data[j][0][0];
    				      let value = c3ArrayFile.data[j][i][0];
    				      if (value !== "") {
    				          obj[key] = value;
    				      }
    				  }
    		
    				  if (id && Object.keys(obj).length > 0) {
    				      result[id].push(obj);
    				  }
    		}
    		
    		runtime.setReturnValue(JSON.stringify(result));
