After cloning or downloading this repo, build the program with make and then run it with ./tetris.
The game will start automatically.
Press left_arrow and right_arrow to move the falling tetronimo left and right.
Press up_arrow and down_arrow to rotate tetronimo clockwise and counter clockwise.
Press space to perform soft drop (drop tetronimo faster).
Press escape at any time to quit the game.
The game ends when a tetronimo stops at the top of the screen.
Your score will be printed out to the console.
Press space to play again.
The game mostly uses the classic tetris rules for rotations. This means there are no wall kicks or anything like that.
The randomization uses the modern tetris rules. This means a 'bag' of the 7 unique tetronimos is created, and a random tetronimo is selected from the 'bag' until it is empty. Then the process repeats.
The gamespeed remains constant for the whole game. See Configuration for how to change it.
Scoring:
20 points for placing a tetronimo without clearing a line
100 points for clearing 1 line
250 points for clearing 2 lines
500 points for clearing 3 lines
900 points for clearing 4 lines
The value tile_len at the top of the .data section in tetris.asm stores the length of each tile in pixels.
The sizes of everything in the game including the window size are based on this value.
If you want to resize the game window to better fit your screen resolution, you should change this value.
The value interval near the top of the .data section in tetris.asm stores the number of milliseconds between gamestate updates.
If the value of interval is 500, then the game will drop the falling tetronimo by one tile every 0.5 seconds.
If you want to change the speed of the game you should change this value.
To change the scoring values, modify the values of, block_placed, lineclear1, lineclear2, lineclear3 and/or lineclear4
in the .data section in tetris.asm
