A very simple and robust implementation of Tetris with C++ and SFML
Left and Right arrows move pieces left or right respectively. Pressing
Down arrow increases the speed of falling 3x times. When released speed
returns to normal. Up arrow rotates a piece.
Game board is represented as a two-dimensional array of size 14x10. The dimensions
of each cell are 50x50 pixels. Each cell is represented with a number ranging from
0 to 6, where 0 means empty cell, and 1-6 means an element. There are corresponding
images to each of these numbers in the img folder.
Element class represents the currently falling element. It is not used to represent
the already fallen elements. When element falls - all coordinates from element are
copied to the board array, and cells are rendered by finding a corresponding color
image. This helps to save memory, as texture data from Element is not stored after
element was placed.
