## Snake in rust using [ncurses](https://docs.rs/ncurses) crate
|
|
|
|
The game is playable
|
|
|
|
run with
|
|
|
|
```bash
|
|
cargo run
|
|
```
|
|
|
|
#### Keybinds
|
|
|
|
hjkl or arrow keys for movement
|
|
|
|
esc or p to pause
|
|
|
|

|
#### Need unicode support in terminal to print the snake
|
|
|
|
The unicode characters used are:
|
|
|
|
- 0x0298 ʘ
|
|
- 0x2550 ═
|
|
- 0x2551 ║
|
|
- 0x2554 ╔
|
|
- 0x2557 ╗
|
|
- 0x255a ╚
|
|
- 0x255d ╝
|
|
|
|
#### Todo :construction:
|
|
|
|
- [ ] Add a way to change the snake speed
|
|
- [ ] Make a ui to switch the snake speed
|
|
- [x] Interal implementation of the snake speed
|
|
- [ ] Implement Highscore System
|
|
- [ ] Make the ui
|
|
- [ ] Internal Implementation
|
|
- [x] Use unicode charachters to draw the snake
|
|
|
|
#### Bugs :bug:
|
|
|
|
- ~~Snake going through the walls~~
|
|
- ~~Food spawning in the walls~~
|
|
- ~~Boxdraw characters not rendering properly~~
|
|
- Remove all the logging in the ui
|
|
- Pausing delayed if esc is pressed but not if p is pressed.
|
|
- The game flickers a lot after sometime (probably due to the constant redrawing of the whole board every tick)
|
|
|
|
#### Maybe in the future
|
|
|
|
- [ ] Autoplay the game using a simple pathfinding algorithm (to show on [r/unixporn](https://reddit.com/r/unixporn) of course :clown_face:)

#### Notes

|
A few notes about the game and how I should improve the game

<summary>A few notes about time complexity and redrawing with ncurses</summary>
|
|
|
|
> The complexity of the program is O(n) every tick (time which changes relative to the speed)
|
|
|
|
> However the place, I can improve is the redrawing of the game
|
|

> At the time of writing the in commit

|
|
> the game still redraws the total board and the total snake every tick.
|
|
|
|
> I think this can be improved by only drawing the parts of the snake and the board when needed

> [char](https://doc.rust-lang.org/stable/std/primitive.char.html) and [std::char](https://doc.rust-lang.org/stable/std/char/index.html) are not the same.
|
|
> [char](https://doc.rust-lang.org/stable/std/primitive.char.html) is the primitive type [std::char](https://doc.rust-lang.org/stable/std/char/index.html) is the char module.
|
|
|
|
> As of Sat, 23 Jan 2021 21:49:13 +0000 the char::from_u32 (used in this program) is not valid in primitive [char](https://doc.rust-lang.org/stable/std/primitive.char.html) but is valid in [std::char](https://doc.rust-lang.org/stable/std/char/index.html)
|
|
|
|
> [ncursesw](httsp://docs.rs/ncursesw) is not needed to print unicode characters. I have no clue where I got that idea from.
