Godot – files in C# in Godot game engine.

Today I tested a new source code with the Godot game engine. The source code recognizes the drag and drop operation for text and image files.

Google Apps Script – reading and store feeds from feedly website – part 055.

You need to have an account with feeds on feedly.com and create a on this website. Open your google drive , create a new spreadsheet and open the Google Apps Script editor. This will allow to use this source code and the result of the running will be add into your spreadsheet:

C – Testing ncurses on linux – 007.

Today I will show a simple source code with two functions. This source code will try to read from a file named level.txt a string like this: 101010100000011111101110101010101 and show empty spaces and square ASCII based on this string. You can compile this source code from a file named screen.c like this:
