pygame 与元组冲突
pygame collision with tuples
所以我正在创建一个贪吃蛇游戏，但我无法检测到它的自我碰撞，我需要了解的是：
我的蛇是一个元组
snake = [(s_pos, s_pos),(s_pos + size, s_pos),(s_pos + size * 2, s_pos)]
就像这样，当它长大时，它会在列表中创建另一个东西，就像上面的代码一直到 snake[3]，我知道如何检测与蛇的前 3 个部分的碰撞，但是当它上升它说索引超出范围，这是碰撞代码
def collision (c1,c2):
return (c1[0] == c2[0]) and (c1[1] == c2[1])
if collision(snake[0], snake[1]):
print("self collision")
有没有办法像
if collision(snake[0], snake[>1]):
print("self collision")
没有索引超出范围？
当蛇长大时它会创建蛇[4]，我不知道如何创建一个代码来检测碰撞，对不起，如果我不清楚，让蛇长大的代码：snake.append((0,0))

检查列表中是否多次存在任何元组的可能解决方案：
def selfColliding(snake: list):
for i in snake:
if snake.count(i) > 1:
return True
return False
或者如@Rabbid76 所指出的，如果您只想检查头部是否发生碰撞：
def selfColliding(snake: list):
return True if snake.count(snake[0]) > 1 else False
如果要测试列表中的第一个元素是否与列表中的任何其他元素相同，可以执行以下操作：
if snake[0] in snake[1:]:
print("self collision")
print(snake[0], "is in", snake[1:])
第一个元素似乎在您的列表中出现了两次。请参阅 并将解决方案应用于您的代码：
direction = 'RIGHT'
direction2 = 'RIGHT'

我发现了（实际上我并没有发现，我只是使用了@rabbid76 的代码，我尝试了一些修改并且它成功了！）怎么做：

我使用@Rabbid76 代码稍作改动，它可以工作！
