animation

问题 I was trying to create these shapes moving, the shape is made up of a semicircle and a symmetric upper arc & lower arc. They should be just the shape in front but now there are line like a tail dragging behind when they move. The output shape with unknown tail It seems like these lines are from the moveTo part of upper and lower arcs, but I can't figure out how to solve it. Where should I change to get rid of it? function Fish(x, y, dx, dy, radius){ this.x = x; this.y = y; this.dx = dx; this

问题 I'm working on a WPF grid listing some Objects. In case the data of the object changes I want to start an animation. Below an excerpt of the XAML code is listed <ListView Name="ListViewEmployeeDetails" Grid.Row="1" Margin="4,109,12,23" ItemsSource="{Binding Products}" > <ListView.View> <GridView x:Name="grdTest"> <GridViewColumn Header="ID" Width="100"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock x:Name="idField" Text="{Binding ID}" TextDecorations="Underline" Foreground="Blue"/>

问题 This question already has answers here : How do I rotate an image around its center using Pygame? (6 answers) Closed 4 months ago . I'm trying to animate a ball getting thrown, and I want it to rotate an follow a smooth, parabolic path at the same time. However, I just can't seem to get pygame.transform.rotate() to cooperate. Here's what I've tried so far: import pygame screen = pygame.display.set_mode((500, 500)) timer = pygame.time.Clock() ball = pygame.sprite.Sprite() ball.image = pygame

问题 I have a situation where I am animating part of my XAML application, and I need to wait for the animation AND rendering to complete before I can move on in my code. So far the tail end of my function looks like: ProcExpandCollapse.Begin(); while (ProcExpandCollapse.GetCurrentState() != ClockState.Stopped) { } } Which, in theory, will wait until the animation is finished. But it will not wait until the rendering is finished - the thread drawing the application might still not have re-drawn the

问题 I can't find the answer to this anywhere, hopefully one of you can help me out. I have a MainView with some content. And with the press of a button I want to open a DetailView. I am using a ZStack to layer the DetailView on the top, filling the screen. But with the following code I can't get it to work. The DetailView does not have a transition when it inserts and it stops at removal. I have tried with and without setting the zIndex manually, and a custom assymetricalTransition. Couldn't get

问题 Suppose I have a Numpy array myAnimation of datatype np.uint8 representing an animation (multiple frames of still 8-bit RGBA images) of shape (y,x,4,k) where y is the height, x is the width, 4 is the number of channels (red, green, blue, alpha), and the k is the number of frames in the animation. Suppose I would like to play back the frames of this NumPy array in PyGame at a specified frame rate (say, 15 frames per second) and have the animation loop. Is this possible to do with Pygame? If so
