Hello! I’m trying to make Dialogue boxes with both Button and Keyboard inputs. The keyboard inputs work but I’m having trouble integrating both Button and Keyboard inputs together. The little light green character is the placeholder for my “Next Button”. There are also red and blue versions of this character representing “Yes” and “No” buttons respectively.
Although I understand the meaning of the error, I don’t understand what’s causing it. I made sure that the entities were initialized in the script and dragged in the respective entities into the scripts in the editor (parse), but I’m sure I’m missing something. Any help would be appreciated!:
Here is my code, apologies for the messiness!:
/*jshint esversion: 6 */
var Dialogue = pc.createScript('dialogue');
Dialogue.attributes.add('text', { type: 'entity' });
Dialogue.attributes.add('textcontent', { type: 'entity' });
Dialogue.attributes.add('answerYes', { type: 'entity' });
Dialogue.attributes.add('answerNo', { type: 'entity' });
Dialogue.attributes.add('yesButton', {type: 'entity'});
Dialogue.attributes.add('noButton', {type: 'entity'});
Dialogue.attributes.add('nextButton', {type: 'entity'});
// define story content
var story = [
{ m: "Welcome to Manis Town!" },
{ m: "The land is sweet and the people are friendly." },
{ question: "Ready to explore? ", answers: [
{ m: "yes", next: "take_yes" },
{ m: "no", next: "take_no" },
] },
{ label: "take_yes", m: "Good to hear! Now go look around, explorer!", next: "take_end" },
{ label: "take_no", m: "That's unfortunate. You're kinda stuck here though, so go look around!", next: "take_end" },
{ label: "take_end", m: "See ya!" }
];
