我有一个类，球弹，当它击中屏幕的限制pygame的椭圆变色碰撞
我当与极限碰撞，但这不变色，保持尝试编程ballchange我的颜色与color_default值并没有改变，我失踪了？
下面是代码：
from pygame.sprite import Sprite
from pygame import Surface, draw, mouse
from GeneralInformation import R, G, B
class Ball(Sprite):
def __init__(self, display)#sorry for bad indent in this example
super(Ball, self).__init__()
self.elasticity = .8
self.radius = 30
self.friction = 1
self.image = Surface([self.radius*2, self.radius*2])
self.rect = self.image.get_rect()
self.rect.x = 100
self.rect.y = 100
self.dx = 0
self.dy = 0
self.color_default = (R+130, G-40, B-60)
self.color_change1 = (R-20, G+20, B+50)
self.color_change2 = (R-40, G+70, B+100)
self.display = display
self.delta_time = 0
self.pos_x_aux = 0
self.pos_y_aux = 0
self.controlled = False
def calculate_gravity(self):
"""Function for calcule the gravity"""
self.dy += .20
def impulse(self, dx, dy):
self.dx = dx
self.dy = dy
def update(self, dt):
self.calculate_gravity()
self.rect.x = self.rect.x + self.dx
self.rect.y = self.rect.y + self.dy
self.delta_time = self.delta_time + dt
if self.controlled:
self.rect.x = mouse.get_pos()[0] - self.radius
self.rect.y = mouse.get_pos()[1] - self.radius
if self.delta_time > 50:
self.pos_x_aux = mouse.get_pos()[0]
self.pos_y_aux = mouse.get_pos()[1]
self.delta_time = 0
if not self.controlled and self.pos_x_aux != 0 and self.pos_y_aux != 0:
self.dx = mouse.get_pos()[0] - self.pos_x_aux
self.dy = mouse.get_pos()[1] - self.pos_y_aux
self.pos_y_aux = 0
self.pos_x_aux = 0
self.check_collisions()
self.draw()
def check_collisions(self):
if self.rect.y + self.radius*2 > self.display.get_size()[1]:
self.rect.y = self.display.get_size()[1]-self.radius*2
self.impulse(self.dx, -self.dy*self.elasticity)
if self.rect.x + self.radius * 2 > self.display.get_size()[0]:
self.rect.x = self.display.get_size()[0] - self.radius * 2
self.impulse(-self.dx*self.elasticity, self.dy)
if self.rect.x < 0:
self.rect.x = 0
self.impulse(-self.dx*self.elasticity, self.dy)
if self.rect.y < 0:
self.rect.y = 0
self.impulse(-self.dy*self.elasticity, self.dx)
def draw(self):
draw.ellipse(self.display, self.color_default, self.rect)
if self.rect.y + self.radius * 2 > self.display.get_size()[1]:
draw.ellipse(self.display, self.color_change1, self.rect)
if self.rect.x + self.radius * 2 > self.display.get_size()[0]:
draw.ellipse(self.display, self.color_change2, self.rect)
if self.rect.x < 0:
draw.ellipse(self.display, self.color_change1, self.rect)
if self.rect.y < 0:
draw.ellipse(self.display, self.color_change2, self.rect)
有了这个代码，我试图按照给我的建议给了我类型错误： draw.ellipse（self.display，self.current_color，self.rect） 类型错误：颜色无效参数

有一个缩进问题 - 请参阅编辑。当你调用draw.eclipse并且所有的类方法都被正确缩进时，它是否仍然会产生问题？ – dmitryro
在我的PyCharm中，所有的缩进都很好，但是我遇到了Stackoverflow中的缩进问题，程序运行了，但是当对象发生碰撞时不会改变颜色，显示Main.py的代码会是一个好主意吗？ –
给予类定义4中更多缩进。问题在于你最初是以元组的形式创建你的颜色，并且元组在python中是不可变的，所以使用不同的数据结构来设置颜色。 – dmitryro
