我有一个x和y位置的数组。我想显示这些点连续为每个点连接一条线，然后创建一个动画。它就像路径跟踪，其路径就是线路。我正在使用python-kivy尝试显示它。
我在google上找不到任何帮助。
有一个触发此动画的按钮。

x_moves = [250, 250.4305, 249.8804, 246.0923, 239.7496, 233.8188, 225.7797, 215.8385, 205.8413, 196.6497, 189.7026, 181.2445, 174.9816, 171.9882, 166.1171, 161.6505, 159.9929, 161.1338, 164.853, 168.2874, 170.768, 178.6918, 184.5233, 190.0262, 195.607, 202.0255, 210.5954, 216.1031, 219.6285, 224.9134, 230.2314, 237.7017, 243.7408, 250.5839, 256.2949]

class my_App(App):
def build(self):
self.widget = Widget()
self.widget.on_touch_down = self.touch
with self.widget.canvas:
Color(0, 1, 0, 1) #just initial config
Line(points = [0,0,500,0,500,500,0,500], close = True) #just initial config
return self.widget
def touch(self, touch): #executes the animation
pts = []
for i in range(len(x_moves)):
pts.append(x_moves[i])
pts.append(y_moves[i])
self.widget.canvas.add(Line(points = pts))
sleep(0.1)
if __name__ == '__main__':
obj = my_App()
obj.run()
这是我的代码不起作用。但这就是想法。
