Introduction

This tutorial looks at a JSON based system for handling and displaying dialogue. The whole example file is controlled by touch (just tap or click to advance the dialogue) and includes ways of showing character names and images. It also includes a function to allow you to apply certain formatting aspects to the displayed text.

  • My god. I've been sitting with this the whole day, not understanding what I'm doing wrong. Looks like I forgot an "s" at the end of 1 word. Never give up people...

    Thank you so much, amazing guide!

  • This is really tough for a beginner. I got stuck at the final return value 'on function format' I could not figure out how to implement the replace() expressions. Even looking at the final .json i could not work out how to enter the 'System ▶︎ Set Line to replace(String,"(b)","[ b]")' or other 3 lines???

  • Sorta newb in Construct, trying to follow this tutorial and am stuck- I added a local variable1, but cannot add another just like it without it having a different name. Will that matter? How did you add an identical local variable when the program doesn't allow it?

    Thank you!

    • I doesn't matter. It's because if you select the function and press V, you create a local variable outside of the function. That's why it doesn't let you name it Variable1 again. I found 2 solutions to the problem.

      1. Just create the Variable2, them move it in to the function and rename it to Variable1 once inside.

      2. Select a condition inside the function and press V(shortcut for creating local variable). That way you can just name it Variable1 right away, since it's inside.

      You probably solved it by now but I thought this might help someone.

  • Thanks so much for your tutorial. I am new to Construct 3. I can't figure out how you added a local variable. I'm on page 3 of your tutorial and I'm stuck. I got as far as LOCAL NUMBER, VARIABLE1 this. How do I add a local variable? And furthermore, how do I add it to the event page? Thanks.

  • still a tiny error on the initial actions, the json command is not load is parse, it was good that the last comment has it right, or I would have never find how to use this.
