我在我的Kivy應用程序中製作動畫,但是所有可用的類都是動畫,只有分散才能正確動畫。問題是,當我觸摸散點圖時,我的on_touch_move()事件根本不起作用。我想做出無法選擇的分散結果Python Kivy使scatter無法選擇
self.do_rotation = False
self.do_scale = False
self.do_translation = False
但這似乎不起作用。如預期的那樣,分散沒有移動,但仍然可以選擇。或者,也許有一個課程適合動畫?我試過了Image,AsyncImage,Widget和Layouts。有任何想法嗎?
@EDIT:這裏是什麼我談論的最簡單的例子:
from kivy.app import App
from kivy.core.window import Window
from kivy.uix.widget import Widget
from kivy.uix.scatter import Scatter
from kivy.animation import Animation
from kivy.graphics import Color, Rectangle
class ExampleWidget(Widget):
def __init__(self, **kwargs):
super(ExampleWidget, self).__init__(**kwargs)
self.size = (100,100)
self.pos = (100,100)
with self.canvas:
Color(1,0,0)
self.texture = Rectangle(size=self.size, pos=self.pos)
def on_pos(self, obj, value):
try: self.texture.pos = value
except: pass
class ExampleScatterTexture(Widget):
def __init__(self, **kwargs):
super(ExampleScatterTexture, self).__init__(**kwargs)
with self.canvas:
Color(0,1,0)
texture = Rectangle(size=self.size, pos=self.pos)
class ExampleScatter(Scatter):
def __init__(self, **kwargs):
super(ExampleScatter, self).__init__(**kwargs)
self.do_rotation = False
self.do_scale = False
self.do_translation = False
self.size = (100,100)
self.pos = (100,300)
texture = ExampleScatterTexture(size=self.size)
self.add_widget(texture)
class ExampleScreen(Widget):
def __init__(self, **kwargs):
super(ExampleScreen, self).__init__(**kwargs)
self.size = Window.size
example_widget = ExampleWidget()
self.add_widget(example_widget)
example_scatter = ExampleScatter()
self.add_widget(example_scatter)
#SCATTER IS GREEN, WIDGET IS RED
example_widget_animation = Animation(pos=(300,100), duration=2., t='in_bounce') + Animation(pos=(100,100), duration=2., t='in_bounce')
example_scatter_animation = Animation(pos=(300,300), duration=2., t='in_bounce') + Animation(pos=(100,300), duration=2., t='in_bounce')
example_widget_animation.repeat = True
example_scatter_animation.repeat = True
example_widget_animation.start(example_widget)
example_scatter_animation.start(example_scatter)
class BadAnimationExample(App):
def build(self):
root = ExampleScreen()
return root
if __name__ == "__main__":
BadAnimationExample().run()
如果您正在爲該窗口小部件上的某個屬性設置動畫,則每個窗口小部件都會正常動畫。 – 2015-02-06 19:13:06
我正在做什麼與小部件是我添加一個圖像,並調用on_pos()函數來更改圖像的位置,每次部件的位置正在像這樣改變:self.image.pos = self.pos。我究竟做錯了什麼? – Nhor 2015-02-06 19:18:45
發佈一些演示該問題的示例代碼。我的第一個猜測是小部件pos永遠不會改變,也許是因爲它的佈局是你沒有考慮到的,但是沒有一個完整的例子就不可能知道。 – inclement 2015-02-06 23:20:41
