Import 2D tiles into Unity

Development of 2D games is one of the first things people attempt when they launch Unity. However, it is not enough to properly import 2D tiles into Unity. We also need to perform a specific set of actions to configure the image. By default Unity does not know how to treat the imported file. You can download the following asset pack.

It is customary to build tileable sprites that may be reused multiple...

Making my first game – Part 1: Conceptualizing

After a year of diligent self-learning I felt more confident around Unity and became relaxed when writing my own code. I always tried to perform coding challenges in tutorials. Very often I managed to write working code which matched the specifications set by the tutors. At the same time the code was quite different from what the tutors wrote themselves. Not to say it was better, but it was fun to compare my solutions to those of more experienced coders. Conceptualizing my game I have just finished a tutorial for a simple 2D tower defense game (parts of which I have...
