I have a game, where on click on one button i load one CCColorLayer. Once i load it, it has some background image. I want the main screen where i clicked the button should also be there when the new layer is opening.
So say new layer's name is image2.png and i already have image1.png. Then image2 is getting loaded on image1. image2 size is less than image1. So whatever parts are visible of image1 i should be able to see meaning by image2 should be transparent. And all these images are in CCLayer background.
Any helps is really appreciated.
Thank you,
Anks.
Sounds like you need to set the size of the layer to be smaller than the first layer, or set the CCLayerColor to be transparent and load the second image as a sprite within that layer.
I just created different scene on same layer as transparent layer is not possible.

I am using Lazarus.
I have put 2 images on a form and synchronized their positions and sizes.
I can textout to both images, and after I made the ontop image transparent I can see the combined content of both images.
I can add further text to the bottom image and see it, but I can't see text I try to add to the transparent image.
I used the following code to make the top image transparent
image2.picture.Bitmap.TransparentColor:=clWhite;
image2.transparent:=true;
I guess I need to play with the image bitmap, but I can't find a solution that is not using other software.
Can someone help me with this please?
I have a window displaying a video stream with a twitter feed as an overlay.
When a new tweet is displayed, the current tweet animates out using a rotate animation and the next tweet is rotated into view. The animations are performed using a RotateTransition.
The app also switches between different cameras to display different streams. To give an indication of when the app switches to the next camera, I have a progressbar that fills using a Timeline object.
This works well, until I resize the window. The rotate animations start to flicker, along with the progressbars as they gradually fill.
As a test, I disabled the video stream, to see what's happening. The 'artifact' doesn't occur then and I can resize as much as I want. If I play the stream and don't resize, everything works well.
The video player is based on VLCJ, but the actual pixels are drawn on a WritableImage in an Imageview.
See the following images that illustrate the problem.
At the bottom right you can see 2 different progress bars (a ProgresBar and a ProgressIndicator).
A part of the flickering result is still visible below the second image. It somehow stays visible, probably because the area doesn't get redrawn.
Any idea what makes the flickering happen? Is there anything I can do to fix or avoid this?
I tried some VM options in IntelliJ: -Dsun.java2d.d3d=true -Dprism.forceGPU=true to somehow enable hardware acceleration, but that doesn't seem to help.
Disabling the progressbar fill animation doesn't help either.
I had a similar problem with some arcs and shapes that would flicker when its attributes / sizes were changed.
The solution to my problem was to make sure that the methods used to change the shapes were called from inside the JavaFX thread.
Platform.runLater(() -> {
arc.setStartAngle(30);
arc.setLength(45);
}
I am trying to use the new 4.6 Unity GUI system to create a bit of UI. I want to make this UI at a resolution of 400x300, then render to a texture which will then be drawn to the screen at a resolution of 800x600 (so double resolution). The problem is this: It doesn't work. The rendering is okay and I can correctly upscale the render texture and have it drawn to the screen, but the UI events aren't received in the correct position, and I can find no way to get around this.
So:
Player resolution is 800x600 Render texture resolution is 400x300
Main camera, called "UI Camera" renders to this texture (at 400x300)
Canvas set to "Screen Space - Camera" pointing at "UI Camera". Under this is a button which is set to stretch to all sides (so fullscreen, 400x300)
A second camera, called "Upscaling Camera".
Another canvas set to "Screen Space - Camera" pointing at "Upscaling Camera".
This canvas has it's GraphicRaycaster component removed. Under this is a RawImage displaying the render texture.
When I play, the UI is correctly rendered to the rendertexture, and then displayed on screen at 2x resolution, filling the screen. What is not working is the events - the button can only be interacted with when the mouse is in the lower-left quarter of the screen.
Conceptually, this makes sense. The button is occupying a space from (0, 0) to (400, 300) (starting at the bottom left of the screen), and now my player's resolution is 800x600, this rectangle only covers the bottom left corner. I get that.
So, with all that said, what can I do to fix this? I can't set the EventCamera on the GraphicRaycaster, so that's out. My next thought was to be somehow fudging the mouse positions. But honestly, I have no clue where to go.
(And in case somebody has a better way of doing this - I'm looking at a game working in 400x300 resolution which needs to be pixel-perfect. If I were to resize all my UI externally, that would mean that in-engine, they are essentially running on a half-pixel grid. Same goes for using the CanvasScaler component.)
Cheers for any help.
there is a task to spread some raster cubes (PNG, with transparent background) along
the canvas based on Paper.JS platform.
I did it, however, there is a bug – canvas is bigger than browser window and when you are scrolling it to the right, animated cubes go glitchy, see attached screenshot. It seems that
the renderer doesn't clear previous frames. The same bug occurs in all browsers.
Is anyone knows how to overcome it? When I am trying to resize window and call onResize, everything becomes good unless I am not trying to scroll it again.

Try using symbols instead of recreating the same rasters over and over:
In you 'building cubes' setup:
sprites[s] = new Symbol(new Raster(urls[s]));
and in hive():
var tmpRaster = sprites[selector].place();
Also, I believe paper.js tries to not animate off-screen elements to save on processing time. Instead of having the canvas be larger than the viewport, you may be better off using view.scrollBy(point)
I'd like to take an image and use it as a mask for a view on which I add numerous image views. I know of the quartz CGContextClipToMask() call but what would be the best way to approach this? Can I override the drawRect method of a container view, call CGContextClipToMask() within it, and then expect its subviews to adhere to that clipping region? It doesn't seem to work.
Do I need to instead add some blocking mask image over top?
Instead of subclassing or overriding drawing functions, I chose to overlay the images with an image that had transparency in the viewable portion. i.e., if my 'surface' was an image of a parchment, and I aimed to draw a bunch of images on it. I would have the parchment image, then a container UIView for any images to be put on that parchment, then a masking image over top of that which was the original parchment image but with the parchment itself converted instead to full transparency, while the surrounding area is left exactly as the background the parchment is on (then all other UI widgets over top of that).
This seems a viable solution in all cases except if one were to need some image to visually animate around and behind the parchment (not my case).
