Tetris game written in Pascal

The software itself was written for a school project.

It was written sometime around mid 2017.

The software is not translated into English, it is only available in Serbian.

The software is built with Lazarus IDE, hence the Lazarus project files.

• Pause menu
• Colourful board
• Instant piece dropping
• Faster piece dropping
• Text rendering from an image
• Tetromino "sack"

The text rendering subroutine TTauGameMain.Ren_Text is located in tau_game_main.pas.

The procedure for drawing text is simple:

1. if the read character is '$', draw the special character according to the next character in the given string.
2. else draw the read character.

The font image is stored in data/tex/char/0.png and it contains not only characters but also small images.

To mitigate the randomness of Tetris, we introduce tetromino sacks. A sack guarantees that the player will get all 7 different tetrominoes during 7 turns. This way the player will not feel cheated, since the player knows the I, straight tetromino, shape will come to him soon enough.

After all tetrominoes from sack are used, new tetrominoes are put into the sack.
