Execute external script

I have a simple script that has "Hello World" displaying using OnGUI. I have uploaded this script to a site, and what I would like to do is have my project access the file, save it to my device, and then execute the saved file.

I have been successful in accessing the file online, and writing it to my device (as a text file), but I cannot figure out how to execute the saved file. I have done many searches online, and I know I could just load the "Hello World" string as a variable, but I'm working on this being the method of updating my project, so I'm looking to be able to execute everything in the saved file. Right now it just says "Hello World" but tomorrow it may have an integer that counts down, or display 2 messages on GUI instead of 1, or any number of other things happening.

Any help will be GREATLY appreciated.

 

I am not sure i completely understand but you might want to look into streamingAssets.
https://docs.unity3d.com/Manual/StreamingAssets.html

This will allow you to add a text file and read it I think. I know of its existence, but have not tried to use it.

Edit: On topic of different parameters, you will have to convert most of the data manually and maybe do a TryParse for an integer.

 

Thank you, I will look into that.

 

You can also use something like MoonSharp LUA to deliver LUA scripts to run in your game after it is compiled.

Otherwise, generally all code has to be in at the moment the executable (or bundle in the case of asset stores like iOS and Android) is created. Code is not truly downloaded in an AssetBundle but rather there are links to use code already in your project at the time it was built.
