Arduboyで狙い撃つぜ！（atan2テーブルの作り方） その７

レーダー法のテーブル作成プログラムを修正した。

atan2関数で各マス目への方向を求めるようにしたので、
角度の分割数や画面サイズの変更にも容易に対応できる。

import math

for y in range(23):
    for x in range(31):
        # 中心へずらす
        cx = x - 15
        cy = y - 11
        # ラジアンから度へ変換する
        angle = math.atan2(cy, cx) * 180 / math.pi
        # 角度を32分割したときにどの値になるか求める
        idx = round(angle / (360 / 32))
        # 今回は全てプラスの値にする
        if idx < 0:
            idx += 32

        print(format(idx, '#2') + ',', end='')

    print('')

前回と結果が異なるが、より自然な方向テーブルが作成できたのではないだろうか。
