Making jssor carousel real responsive - jssor

Well, I am not expecting anyone else but jssor himself again to help me out with the best image slider plugin he made(jssor helped me earlier on stackoverflow). I wanted to make the jssor carousel responsive in terms of reducing the number of images shown inside the slide. As of now, the size of the images inside the carousel gets reduced as we move on to smaller resolution devices. However, at some point, this images look real tiny and are not desirable. This issue can be fixed, if we reduce the number of images shown inside the carousel for smaller screens. Like if we are showing 5 images on a larger screen, how do we show only 2 for considerable lower screens?
Waiting on you jssor!!! Keep on the good work you've done!

You know all elements in the slider will scale while window resizing.
As you set small size of your slider, and it scales to bigger size, the arrows looks bigger then.
2 ways to prevent it from scaling bigger.
first, Make the original size of slider bigger, it will prevent the slider from displaying with large scale ratio.
second, Suppress the arrows from scaling explicitly with data-noscale="1".
<span data-u="arrowleft" class="jssora13l" style="top:0px;left:30px;width:40px;height:50px;" data-noscale="1"></span>
<span data-u="arrowright" class="jssora13r" style="top:0px;right:30px;width:40px;height:50px;" data-noscale="1"></span>
Example: suppress arrows from scaling - jssor slider

How to keep the same resolution of canvas on different screen resolution?

First of all, sry for my English mistakes, I'm not a native English speaker.
I'm trying to make an UI which is composed of a canvas within different gameObject, and I would like that my canvas scales to the dimension of the screen but keeps its original resolution (16x9 portrait). If it is displayed on a tablet resolution (4x3) then an image is displayed in the space that is not covered by the canvas.
But actually all I've got is a canvas which scales to every resolution, and it changes the aspect of its child (for example a square becomes a rectangle).
Thank you for showing interest in my query!
UI's are heavy beasts. Canvas in Unity have a component attached to themm called Canvas Scaler which is set by default on Constant Pixel Size. You may try to set this property on Scale With Screen Size and then specify the base resolution you want to work with (usually 1920x1080 is a console standart). This is your first step
Then, to avoid strange Image scaling, you may check the property Preserve Aspect, this way the ration of the Sprite into your Image will remain the same indepently of the ratio of the Image
Last, you may play a bit with anchors but this is another story, you should let those at plain center at the beginning and come back to it when you will feel ready
Hope that helped ;)
Your canvas should have a component called Canvas Scaler. Here it should say Constant Pixel Size, change this to Scale With Screen Size and it should lock the Canvas to be the same width / height as the screen. If you want to lock an image to a specific width/height ratio, go to the Image component on the image and check the Preserve Aspect checkbox. This way if you have a 100x100 image, the images width will always be the same as the height. If you have a 200x100 image, the images width will always be twice the height, etc etc etc.

How do I make my 2D game responsive to different resolutions?

I making a 2D game in unity. And I want to make my game responsive to different resolutions, and when I use Canvas Scaler all my UI objects become very bigger.
if you can help please response.
thank you!
Designing UI for Multiple Resolutions
1. Using anchors to adapt to different aspect ratios
One way to keep buttons inside the screen is to anchor them to their respective corners,
One way to keep the buttons inside the screen is to change the layout such that the locations of the buttons are tied to their respective corners of the screen.
Once the buttons have been anchored to their respective corners, they stick to them when changing the resolution to a different aspect ratio.
When the screen size is changed to a larger or smaller resolution, the buttons will also remain anchored to their respective corners. However, since they keep their original size as specified in pixels, they may take up a larger or smaller proportion of the screen.
2. Scaling with Screen Size
In the Canvas Scaler component, you can set its UI Scale Mode to Scale With Screen Size. With this scale mode you can specify a resolution to use as reference. If the current screen resolution is smaller or larger than this reference resolution, the scale factor of the Canvas is set accordingly, so all the UI elements are scaled up or down together with the screen resolution.
The layouts will appear the same in different resolutions, only with a lower pixel density depending on if you scale up or down.
One thing to be aware of: It can be possible that some element are larger in landscape aspect ratio. This can be fixed if you change the Match property to 0.5 instead, it will compare both the current width to the reference width and the current height to the reference height now.

How to make responsible camera for multiplie resolutions?

I m working and some 2d game for mobile phones relate to chess, and I have a trouble with show board for different resolutions of mobile screens.
Here u can see how it must be on 9:16 resolution:

And how it looks on smaller screen:

How can I protect my chess board from cropping?
Answer: it depends on how you want it to look.
If you just want it to fit perfectly horizontally, you need to perform 3 steps:
Evaluate the width of the Sprite (with Sprite.bounds)
Evaluate the width of the current screen (with Screen.width and using the main Camera)
Scale the Sprite to fit the screen
If you are using UI elements, you can do the same thing but you won't need to use Camera, just scaling according to the Screen width (look for RectTransform.deltaSize to give you the size of a UI element).
If you are using UI, also consider using layout groups, they help you with fitting the content to screen size.
Anyway, in a device with small width, maybe the table will get too small and you might have to think about better options to display the board instead of just scaling with screen width.

Image in a fixed size box?

I'm trying to display images in a fixed size box (the grey area in the image here). When the submit button is pressed new images will be fetched from the internet. But the images will be different sizes.
So to prevent the "submit" button moving up and down due to different size images (and potentially having it off the screen) I'd like the images to fit inside the box. (I suppose there are a few options there, for example having the image resize to fit in the box or having the image be clipped and still fitting in the box.) I've been messing with containers and columns etc for ages but nothing seems to work.
what is the best way to fit images of different sizes into a fixed size box ?
The Image widget can have a height be specified. You can read more about that here

Webdesign: PNG-Image width limitations

I want to make a kind of slideshow based on scrolling the webpage.
My problem is that I have an image width of 78720x1015px in png-format.
The width of the image is determined by one single image of 1920px which is 41 times arranged next to each other. - It should be like a cartoon where an image moves by 100% (margin: -100%) and generates a feeling of a movie.
However, this results in an image width of 1920px x 41pics = 78720px.
This is of an enormous width, but what I am wondering about is that the filesize is only 975kB which is in my opinion not that big!? - However, somehow it takes a very long time to load the picture in the Webbrowser and the image is not of such quality as in my ImageViewer on Desktop.
Question 1: What do I have to consider when dealing with such a big image-width? What are the limits?
Question 2: Is there a better way make such kind of a slideshow? - Consider that the sliding itself shouldn't be visible. It should be like a movie based on about 40 pictures.
Thanks in advance!
PNG compresses very well, especially if it's a cartoon like you say that may use only a limited number of colours.
However, when loaded into memory, the device must load all that pixel data into RAM to display it. That's almost 80 million pixels in your case, which would be around 320Mb of uncompressed data. This is probably why the browser is struggling, and especially so if you're using margin to move it around as that requires a full re-draw of the image.
You may have better results with transform, as this should use hardware acceleration and also avoids the reflow part of a redraw since transforms don't affect page layout.
But the better solution would be to break it down into individual images. Have your code load in the next image, scroll it across, then load the next while scrolling and unload the one that's now off-screen to provide a relatively seamless view.
