[英]cannot create surface even though it seems correct
self.image = pygame.Surface(
int(math.sqrt((end_pos[1] - start_pos[1])**2 +(end_pos[0] - start_pos[0])**2)), width)
returns the error:返回错误:
ValueError: size needs to be (int width, int height)
The argument to the constructor of pygame.Surface
is a tuple with the size of the Surface ( pygame.Surface((with, height))
): pygame.Surface
的构造函数的参数是一个具有Surface大小的元组( pygame.Surface((with, height))
):
self.image = pygame.Surface(int(math.sqrt((end_pos[1] - start_pos[1])**2 +(end_pos[0] - start_pos[0])**2)), width)
self.image = pygame.Surface(
(int(math.sqrt((end_pos[1] - start_pos[1])**2 +(end_pos[0] - start_pos[0])**2)), width))
respectively分别
value = int(math.sqrt((end_pos[1] - start_pos[1])**2 +(end_pos[0] - start_pos[0])**2))
self.image = pygame.Surface((value, width))
