將幾個立方體放入 pygame
[英]drop several cubes in pygame
問題描述
我上周開始了 Python 並且我正在嘗試創建一個游戲來學習。 屏幕中有 4 個移動圓圈，從屏幕中間移動到 4 個邊緣。 我想得到這部分。
現在我正在嘗試將立方體從 4 個邊緣放到中間。 目標是通過按鍵盤箭頭阻止這些立方體到達屏幕中間。 如果一個立方體到達中心，則游戲結束。
我設法同時將 4 個立方體丟到中間，但我的想法是隨機丟幾個立方體。
知道我應該如何繼續創建這個嗎？ 或者我應該學什么才能做到這一點？
到目前為止，這是我的工作：

我認為這里的答案是修改你的Enemies object 以便它作為更通用的 object 更好地工作。
為此，我修改了 class 以使“立方體”從側面的隨機 position 開始，並且始終進入中間（我不確定這是否正是您的計划，但這是我對您的游戲的解釋描述）。
這是通過計算方向矢量（因為它現在可能是對角線），然后將此量（乘以速度）添加到每個“滴答”的位置來實現的。 這造成的一個問題是，如果方向的分量非常小——比如 0.1 像素/刻度，那么這個量的相加總是四舍五入為零。 因此 class 將該位置保留為浮點數，並且僅在更新 Rect 時轉換回 integer 。
代碼現在保留了Enemies對象的列表。 這使得遍歷這個列表、更新、繪制和檢查位置變得容易。 要添加更多敵人，只需在此列表中添加額外內容 - 也許隨着級別變得越來越難。
如果提供的坐標為 (0,0)，則下一個更改是讓敵人從隨機 position 開始。 這允許代碼將舊敵人重新設置為新的隨機起始 position，或添加新敵人。
