如何使用我的播放器的座標和陣列中任意塊的座標來檢測碰撞？

Question

我有解釋的數組：

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] 

A 1表示的塊。 A 0表示開放空間。 每個數字是一個50x50像素塊/空間。 使用blockList [y] [x]我可以單獨找到每個數字。

y表示列表組中的哪個列表。 x表示列表y中的哪個數字。

但是我沒有在我的代碼中使用x和y。

我有一個角色是50x50像素，如果我使用箭頭鍵，每個循環移動10個像素。

如何檢測我的播放器和數字1之間的碰撞？

我曾嘗試：

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 

我曾嘗試一些其他的方式，但我擺脫他們的時候，他們沒有工作。

任何幫助表示讚賞。 任何問題都將盡快回復。

感謝

（我已經改變了塊大小爲20，但你可以輕鬆地調整回來。）使用Z/X/P/L到移動播放器。
