Story's decisions generic tree graph

Getting Started
1

Hello!
I’m not sure if this is the forum I should be asking, but it feels like a quite basic question.
I need to develop a generic tree graphic of the decisions made by the player through the story.
By generic I mean that every node can have n childs, and nodes should be connected by a dotted line.
Nodes are also shown with a small screen capture.
I need some orientation to face this problem as I am not sure how to do it.
Thanks in advance!

Hmm, tricky.

Well, for drawing the lines and boxes on screen, @Senshi 's Primitive UI might be just the ticket. It’s not exactly easy to use, if you’re a complete beginner. But it certainly works.

If you mean to create a document of your graph, then you should look instead at writing out a DOT file. These are easy to create and there are a variety of apps that can read them. I’m not sure about including images on each node, though.

As for actually creating the images, Application.CaptureScreenshot is probably what you need.

HTH,

Thanks a lot for the orientation. I have chosen to create my own tree structure.

My main problem right now is loading the screenshots. I’m not sure of the best way to do it. I’m using:
Application.CaptureScreenshot (Application.persistentDataPath + “/” + name + “.jpg”);
to create the screenshot.

How should I load it the fastest possible way? I’ve seen some codes using System.IO.File, but I doubt Unity hasn’t got an improved way to do it.

No, that’s it. System.IO.File to read the bytes, then pass them to Texture2D.LoadImage.
