I want to create a slider without an outline.
Like this one:
Note rounded edges.
I assume I need to create a sprite for that. Unfortunately, I can't find any good tutorials on sprites for sliders. I think the easiest way would be to edit the built-in one but I don't know how to get it for editing.
This is how the original slider from my Unity looks like:
Note the outline.
So, surprising solution that should be available to all of us.
Put the default slider in and go to the Source Image for both the Background and Handle. Instead of using what is there, change it to another Unity Standard sprite called TouchpadSprite. This should do the trick. Not sure if the fact that this is called 'touchpad'sprite will cause a problem when make a PC game, but I doubt it. FYI the TouchpadSprite is from the "Standard Assets (for Unity 2017.3)" that is available for free in the Unity Asset Store. Feel free to only import the sprite itself. The Asset Pack itself is pretty large, but there is a lot of good/useful stuff in there.
Also, you will have to increase the Pixels Per Unit Multiplier value. My picture shows what I had to increase it to. This will allow you to choose the rounding of your edges as well. Play with it and let me know if it works.
Hope this helps!

I'm new to Unity so Hopefully this is an easy fix.
So everything looks super low res for me. I wish my images looked high res.
Even SVG looks low res even though they're vector nodes, I don't get that at all but I assume Unity doesn't play with svg yet? the black outline graphic is SVG, the rest are PNG with alpha.
Take a peek at my three different windows. Let me know your suggestions (remember I don't know anything so the easiest thing can been overlooked)
There is a "Scale" slider on top of the game view. Right now it is set to 2.8x. When you do that Unity just zooms in but it doesn't set the the resolution or actually change anything at all. It's like moving the screen really close to your face :D Nothing else besides that particulat window is affected by this setting. So my advice would be to always keep it at 1. Unless you want to see something specific at the screen of course
I am using the camera for reading some text and currently, my images look quite blurry
Is it possible to change the focus of the camera?
I am using
https://www.raspberrypi.org/products/camera-module-v2/
Yes, it's definitely possible, I did it many times. Sometimes in the camera box there is even a specific tool to rotate the lens included (check if you have it, I experienced that it's not always present). If you don't have a tool take thin pliers and rotate the lens, you can look here.
I have the, in my opinion, simple problem of disabling image detection with the AR Camera. I have the problem, that my app detects an image from the image library and spawns an object etc. everything according to plan.
But the problem is that if move the camera over another detectable image, it recognizes it. This is bad not because it spawns something additionaly but because you can "collect" the images in my app, so it unlocked the other detected one even though it shouldn´t.
So how can I disable image detection without turning off the AR-Camera?
I so far tried to simply disable the "ARManager" and the "ARTrackedImageManager" script (.enabled=false), but it didn´t solve my problem, because the app still detects other images.
Hope I could explain what my question and problem is properly. Any help is appreciated!
It really depends on what library you're using to detect the image. Generally, most marker tracking libraries will create a marker object in your Unity scene. You can disable these marker objects after you find one, and only leave the marker you're interested in. Make sure you also set the number of tracked images to 1 so you won't accidentally find two markers in one frame.
I am creating an application in Swift, and I would like to make an introduction screen that shows off my logo. I want the logo to slam down on the screen, which will then cause a crack, and then that crack slowly grows. I think I can figure out slamming the logo down (by shrinking a UIView of my logo to a certain point), but I am having trouble deciding how to create the crack that will form from slapping down. Do I use views? I am lost.
This is the closest thing that I found to what I would like to do. Sadly, I do not have this software.

I have created a similar effect before. And to achieve the crack a created multiple images of a growing crack and created an array of images for that screen crack. All you have to do then is animate the images if the imageView.
The other way you can Handel this is to actually draw the crack your self by code which is not difficult really, because in reality it’s just lines and then animate them. But in my experience just using the first method gives a much nicer effect because the images you use can have tons of effects using PS or equivalent.
I would suggest to go with third party like lottie. In lottie files there some animation you except there, you can also message the designer to help out animation. Its very simple to use in swift.

Lottie animation are done in aftereffects using bodymoving extension and exported as json file to use in xcode.
I'd like to allow a user to add a shape (which would just be a UIImage) onto some sort of canvas, then move and resize it on the screen but I'm not sure how to go about this. Ideally I'd like the basics of a drawing app which can use images from a user's device. Each shape would have an associated position, size and z-index.
The only thing I'm unsure of is how I'd create a bounding box (the one with four blue dots to allow resizing/moving). I have experience with UIKit, and would prefer to keep the majority of the app in this for the time being, but I get the feeling this type of thing might be better suited to Cocos2D or a similar framework.
If anyone has any pointers/open source code I can dig through it would be hugely appreciated.
I think you should look into CALayer, or even CAShapeLayer. I'm just starting to play with them, but I'm pretty sure you can easily get the functionality you want with either. Draw the border in the layer's drawLayer:inContext:. Check out the Quartz2d Guide path drawing section for the functions you need.
