termbox-tetris's Issues

[Core Feature] - Display Next Piece

Core Feature

Like most Tetris games, the piece that's next up should be displayed somewhere (most likely in a box next to the board).

Visual Artifacting / Corruption

Describe the bug
The screen gets filled with a small or large amount of garbled text, which doesn't go away until something (e.g. a game piece) moves overtop it.

To Reproduce
Reproducing is inconsistent, and I'm not yet sure what causes this to happen; however, I most often see it when clearing a line (i.e. when a line/row fills up and is cleared out).

Expected behavior
Obviously, this garbled text shouldn't show up. In fact, every call to render() performs a tb_clear() first, so I'm not sure how the junk persists on the screen even after that.

Screenshots

Environment:

• OS: Ubuntu 20.04.1 LTS running on top of WSL 2, in Windows Terminal
• Compile flags/command: gcc -Wall -Wextra -pedantic ./tetris.c -lm -lpthread

More Robust Handling of Window Resize Events

We are currently checking the size of the window/terminal on launch to make sure there's enough space; however, we should re-check every time the window is resized as well. Resize events are captured by termbox, so this should be simple.

If the user resizes the terminal to be too small, it would likely be best to pause the game and display a message asking them to resize.

Implement Terminal-Size-Aware Scaling

Is your feature request related to a problem? Please describe.
With current configuration, the game can be small, only occupying roughly 20x20 characters in the terminal.

Describe the solution you'd like
A scale factor should be added to the game that controls how large the rendered squares are from draw_block(...). The game could also intelligently choose the largest possible scale factor (constrained by terminal character width/height) on startup and after any window resize events.

Describe alternatives you've considered
Most terminals worth their salt let you resize text anyway, but having this native would be cool.

Add Support for Extended Colors

Is your feature request related to a problem? Please describe.
The game currently runs termbox2 in its default output mode, which only offers 6 colors other than black and white. Unfortunately, there are 7 tetrominoes, meaning that either 2 pieces have to share a color (undesirable), or one of the pieces needs to be white.

Describe the solution you'd like
Adding support for additional colors, for example via termbox's 256-color mode would alleviate this problem. Not all terminals support this mode, so it may be wise to include a compile/run flag that defaults the game to its regular 6-color mode.

Add Compile Instructions

I discovered this nice little Tetris game to evaluate termbox2. Please add some compile instructions to the README.

I got it to work with this:

gcc -lm tetris.c -o tetris

Nice work!

[Core Feature] - Scoring and Levels

Core Feature

Players should accumulate a score by clearing lines, etc., and certain score thresholds should increase the "level."

Successive levels will be more difficult, with pieces dropping quicker.
