pygame中发生碰撞后如何删除图片?
作者:互联网
我正在制作一个使用python进行通电的游戏.有一个随机产生的机会,它会在屏幕上变白其图像.一旦玩家的身体(在这种情况下为队长)与之碰撞,它就会从列表中随机选择一次加电.我正在检查图像位置(相同大小)处的矩形的碰撞,并尝试删除该矩形,并在发生碰撞时删除该图像.我怎样才能做到这一点?到目前为止,这是我的尝试,但是,我仍然收到错误:“列表分配索引超出范围”,并突出显示以下行:del PowerYList [Spot].有人可以告诉我我在做什么错吗?
if random.randint(1,2500) == 2500:
PowerY = random.randint(125,585)
PowerRect = Rect(930, PowerY, 50,50)
PowerYList.append(PowerY)
PowerRects.append(PowerRect)
for X in PowerYList:
Screen.blit(PowerUp, (930, X))
Radius = 0
for X in PowerRects:
if X.colliderect(Rect(942, CaptainY, 15, 30)) == True:
Power = random.choice(PowerUps)
Power = "Nuke"
Spot = PowerRects.index(X)
del X
del PowerYList[Spot]
if Power == "Health":
if Health <= 85:
Health += 15
else:
Health += 100-Health
elif Power == "Nuke":
Radius = 0
for Y in range(1,50):
draw.circle(Screen, ORANGE, (500, 350), Radius+50)
draw.circle(Screen, RED, (500,350), Radius)
Radius += 5
Gigabits = []
Gigabits_Heads = []
Gigabit_Health = []
S_Gigabits = []
S_Gigabits_Heads = []
S_Gigabit_Health = []
