The goal of this project is learning about game programming using Godot by following the Godot Game Development Tutorial (Tetron) created by GDScript Dude.
I modified stuff here and there while going through the tutorial and continued adding some extra features. Some of these changes/features are:
- Code style. I wrote some parts of the code differently either for learning or just because I used different conventions.
- Landscape layout.
- Game stops while clearing complete rows. In Tetron there is a pause using yield that doesn't prevent the new shape of start falling down while there completed rows are still being cleared. In addition, using yield returns to the caller so it continues its execution even when the called function is still executing. I added specific checks for completion of the called functions in order to control the execution flow.
- Fixed a bug that caused the straight shape (I) not to move to the rightmost column when it is rotated 270º.
- Added some extra time to allow to move and rotate the shape before locking it to the grid.
I won't keep this list updated with new features or differences with the original code explained in the tutorial. In case you are here trying to find a direct correspondence with the tutorial, please visit Tetron repository. I'll try to document the game mechanics and options I implement, and let you dive into the differences if you want to :-).
