I tried to implement next progress bar in my react app.

For now, I am using next code

I have a ToggleButton and an ItemsControl. The ItemsControl's items have a DataTemplate. How can I animate each of ItemsControl's items, when ToggleButton's check state is changed?

In the following code, you can see when the user clicks on the ToggleButton, the chevron rotates. I want the items in the ItemsControl to animate as well. I added a Storyboard with the key "ItemAnimation". I think somehow it should be triggered when the user clicks on the button.

I'm trying to make a platformer with a parallax background. I managed the code and also made sure to add .convert. It is running pretty well for the most part, but every now and then there are periodic lag spikes.

So I have been trying to fade an image in and out. I found this tutorial and I copied the code exactly and changed the images to my images, but it comes up with errors;

I use MPChart to plot rapidly updating data live. It is crucial that the user can freely scroll along the Y-Axis as the graph gets updated. After every update, I use myChart.moveViewToX() to automatically scroll along the x-axis. However, moveViewToX() also moves the view to 0 along the Y-axis.

Since moveViewToXdoes not feature a parameter like "ignoreY" or "keepY", I would like to use mChart.moveViewTo(centerX, centerY, YAxis.AxisDependency.LEFT);, where centerY is the Y-Position that the user has scrolled to.

So far, I have not found any way to access this value in the MPChart documentation.

The json document is like this. I want to define a class for it in qml, just like the interface keyword in typescript does.

My idea was to safe the rectangles in world[] to then move them every game tick to the left by using: velocity_map. The class World is only for creating the pattern of rectangles, that are supposed to move. I want this pattern of rectangles to move to the left, but instead of moving them, a lot of new ones, will be created wihle moving to the left, but the old ones are not beeing removed by the pygame.display.update() function. How do I move the them correctly?

So I've been working on an ant simlulation like project and I've encountered this issue and replicated it here. In essence what I did is draw a circle every surface update at the location of the cursor using pygame.mouse.get_pos().

But somehow I'm getting this issue where the location of the circle is way off the cursur by growing intervals when you move the cursor away from the top-left side of the window. There's also this graphical glitch where it seems that the cursor brings along a fixed surface of the window itself that contains the surface update of the objects behind the circle and the circle itself moving inside it. It also blocks the object's actual surface behind this window as you can see from the link below.

I've looked around online and so far I'm not even close to solving this issue. I'm not sure if it's a surface layering problem, a problem with my logic or if it's a glitch inside pygame. In any case here's the code below to replicate the problem.

I am creating a simple 2D platformer in Pygame. In this project I have been trying to use classes much more for good practice. My current problem is that I am trying to make the screen center on the player, however I cannot find a way to do this with the way my code is currently set up.

In addition, I plan to later add a way to make the screen follow the player with a small amount of lag, following faster as it gets further away. However, making the camera center on the player is my main concern.

When the player is moving right, I have all the "PlatformRects" move left at the same speed. I have tried different speeds, setting the player to zero speed and just moving the "PlatformRects" almost works (related comment in code in the "update" func of the "Player" class). I had also tried making the "PlatformRects" movement depend on the position of the player, but I couldn't get this to work either.

I would appreciate any help. Here's my code (I trimmed out a lot of irrelevant code, like animating and such):
