我试图制作一条在曲线上移动的船，但我只是设法让它从一个点移动到另一个点（直线）。我想让它像一条船在一个国家周围移动一样弯曲，因为它不能越过陆地。
class virus(object):
moveRight = [image.load("res/virusMove/right1.png"),
image.load("res/virusMove/right2.png"),
image.load("res/virusMove/right3.png"),
image.load("res/virusMove/right4.png"),
image.load("res/virusMove/right5.png"),
image.load("res/virusMove/right6.png"),
image.load("res/virusMove/right7.png"),
image.load("res/virusMove/right8.png"),
image.load("res/virusMove/right5.png"),]
moveLeft = [image.load("res/virusMove/left1.png"),
image.load("res/virusMove/left2.png"),
image.load("res/virusMove/left3.png"),
image.load("res/virusMove/left4.png"),
image.load("res/virusMove/left5.png"),
image.load("res/virusMove/left6.png"),
image.load("res/virusMove/left7.png"),
image.load("res/virusMove/left8.png"),
image.load("res/virusMove/left5.png")]
def __init__(self, x, y, width, height, end):
self.x = x
self.y = y
self.width = width
self.height = height
self.path = [x, end]
self.moveUnits = 0
self.vel = 5
def draw(self, screen):
self.move()
if self.moveUnits +1 >= 24:
self.moveUnits = 0
if self.vel > 0:
screen.blit (self.moveRight[self.moveUnits//3], (self.x, self.y))
self.moveUnits += 1
else:
screen.blit (self.moveLeft[self.moveUnits//3], (self.x, self.y))
self.moveUnits += 1
def move(self):
if self.vel > 0:
if self.x < self.vel + self.path[1]:
self.x += self.vel
else:
self.vel = self.vel * -1
self.x += self.vel
self.moveUnits = 0
else:
if self.x > self.path[0] - self.vel:
self.x += self.vel
else:
self.vel = self.vel * -1
self.x += self.vel
self.moveUnits = 0
然后我做了类似
的事情def drawScreen():
virus.draw(screen)
virus = virus(100, 640, 64, 64, 750)
然后我把drawScreen放在我的运行循环中
