如何使用我的玩家的坐标和数组中任何块的坐标来检测碰撞？

Question

我有列表数组：

blocks0 = [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 ,1 ,1 ,1 ,1]
blocks1 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks2 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks3 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks4 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]                   
blocks5 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks6 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks7 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks8 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks9 = [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks10= [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ,0 ,0 ,0 ,1]
blocks11= [1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 1, 1 ,1 ,1 ,1 ,1]

blockList = [blocks0, blocks1, blocks2, blocks3, blocks4, blocks5, blocks6, blocks7, blocks8, blocks9, blocks10, blocks11]

1 表示一个块。 0 表示开放空间。 每个数字是一个 50x50 像素块/空间。 使用 blockList[y][x] 我可以分别找到每个数字。

y 表示列表组中的哪个列表。 x 表示列表 y 中的哪个数字。

但是我没有在我的代码中使用 x 和 y。

如果我使用箭头键，我有一个 50x50 像素的角色，每个循环移动 10 个像素。

如何检测我的播放器与数字 1 之间的碰撞？

我试过了：

lefX = x
rigX = x + player_width
topY = y
botY = y + player_height

lefX -= int(lefX % 50)
rigX -= int(rigX % 50)
topY -= int(topY % 50)
botY -= int(botY % 50)

lefX = int(lefX/50)
rigX = int(rigX/50)
topY = int(topY/50)
botY = int(botY/50)

if blockList[topY][lefX] == 1:     ##This is just for going left.
    if not((blockList[topY][lefX]*50)+50 >= x):
        x += x_changeLeft
else:
    x += x_changeLeft

我确实尝试了一些其他方法，但是当它们不起作用时我就摆脱了它们。

感谢任何帮助。 任何问题都会尽快得到解答。

谢谢

（我已将块大小更改为 20，但您可以轻松调整回来。）使用 z/x/p/l 移动播放器。
