Getting text from .txt File

Not sure whether to put this in Scripting or here, but is it possible to get text from a text file and place it in a UI Text component?
This is for a book system and I don't think I would be able to do this any other way.

 

You can use Resources.Load to load TextAssets from within your project. They need to be .txt files in a Resources folder of your project.
Another option is to use the C# way of reading files, there are a few ways to do that.
As far as the Text component though, there is a hard limit on how many characters you can load into a canvas. I only mention because if you are not careful loading a books worth of text into Text.text you'll probably get an error.

 

As above. In my project I use a mix of Unity's TextAsset which is easily read by one line of a code- this for the type of text files that will be bundled with the game and so not edited by the end user. For other files that the end user will edit, i.e. located outside the project, I use the C# StreamReader. It's also really easy to use, just a few lines to read a external file.

As for the text limit, I'm not sure what it is. But I would probably create a empty Text UI GO with a Layout Element component and make it a prefab. Read your text, split it up into smaller chunks then just instantiate prefabs in a loop, filling it with chunks as it goes. Then slap a Layout component onto it's containing panel to keep things looking good.

 

This all worked, after reading a bit on TextAssets, this worked very well, thanks.
