テトリス風落ち物パズルを作る part04 ミノの設置とライン消去

Last updated at Posted at 2024-06-14

前回はキー入力と落下処理を行った
今回はミノの設置とライン消去を行う

ミノの設置

落下処理が失敗した→地面に着いたなので
地面についた状態から少し動かす余裕を持たせるために
カウントダウンしていく

# 床に着地しているかのチェック
is_floor_landed = not self.can_mino_move(self.mino, Pos(0, 1), 0)
if is_floor_landed:
    self.wait_count -= 1

移動処理のタイミングでカウントが基準値を下回ったら設置する。

def move_and_rotate_mino(self):
    if self.wait_count <= WAIT // 2:
        self.wait()
        return
def wait(self) -> None:
    if self.wait_count == 0:
        self.mino_setup()
    else:
        self.wait_count -=1
    if self.wait_count == WAIT // 2  - 1:
        # print(self.mino.p)
        self.put_mino()
        self.line_check()
    if self.wait_count == 1:
        self.clear_line()
def put_mino(self):
    self.is_draw_mino = False
    m = self.mino
    for p in m.get_shape():
        self.matrix[p.y][p.x] = m.m.tile

マップの編集

ライン消去用に消えるラインを別の色のブロックにしたいが
どうやらpytmxはマップ上にタイルを設置しないと表示できないみたいなので
mino_data.tmxを編集する。マップの幅を1増やして一番右下に灰色のブロックを追加した。

追加したタイルを使えるようにmino.pyにクラスを追加する

class OtherTiles(Enum):
    Vanish = "Vanish", -1, Pos(28,15)
    def __init__(self, name, value, p):
        self._name = name
        self._value_ = value
        self.tile = tmx_data.get_tile_gid(p.x,p.y,0)

    @classmethod
    def values(cls):
        return list(cls.__members__.values())

ライン消去

ライン消去の処理を追加する

def line_check(self):
    for y in range(19, -2, -1):
        n = 0
        for x in range(10):
            if self.matrix[y][x]!=0:
                n += 1
        if n != 10:
            continue
        else:

                self.matrix[y][x] = OtherTiles.Vanish.tile

動作確認

実行して操作した様子の録画。

1ライン消し、複数ライン消しともに実行できているのが確認できる。

まとめ

ミノ設置とライン消去を実装した

これで最低限遊べる状態になったけど遊びづらいので改良していく
