How to create editable 3d animations for IOS - ios

Can someone advise what tools should be used to implement such a task ?
We have a virtual avatar in our application, whose settings allow us to change its equipment / inventory. When you change the equipment in the settings, the new avatar skin is displayed in the application on different screens already with new items (it can be weapons, clothes, shoes and other things). At the moment we use Lottie animations for this, in which we edit json nodes from swift code, but this is too heavy from performance and smoothness point of view
Is there any way to do a similar 3d character editor without using tools like Unity ? I'd like to avoid a long transition between the ios app and the Unity scene load
I know of several apps that, for example, let you edit the colors of objects (like seven, in which you can change the color of the character and his clothes) or their configuration. Is it possible to implement this with SceneKit ?

Manage different classes MonoGame XNA,

I'm making a game in MonoGame with several states. It is very complicated to manage all this in the same class. Is there a way to divide these states with different objects and properties between different classes?
I want to manage the same modules: Draw, Update, load content but focused on other states of the game.
If by different states you mean something like different game screens (menus, main game screens, maps) you can create a game screen class which then contains the functionality required for the current state and overrides Draw, Update etc methods. You can create a different game screen for every map or just one map screen which then loads the map externally etc.
Then create a class to manage current game screens which has methods for changing active game screen (creating new instances by activator and setting it as current screen object) and calling the current screens update & draw methods via override. The main game loop will then call the screen manager without having to worry about knowing the current state.
I found this particular tutorial series to be really helpful since it explains on how to create game screens, screen managers etc: https://www.youtube.com/watch?v=agt9-J9RPZ0 (C# Monogame RPG Made Easy Tutorial by CodingMadeEasy).

Selection of Canvas or Panel or Scene for UI in Unity

I am making an iOS application using unity.
We have 3 options for UI elements such as button, user's text key in and image, logo display etc.
I have about 8 pages in my iOS app. The first page is user login, second page is selection buttons for different game levels, third page is display of previous results, etc.
I am making UI pages and I am wondering which option to choose in terms of game's response. As this is my first app using Unity, I like to have opinions from expertises.
Which options would be best for game response and unity design among the followings.
(1)All pages are designed on different scenes and I will have 8 scenes. Each scene has its own UI elements.
(2)One scene, but different canvases for different pages. So each canvas has its own UI elements for different pages.
(3)One scene, one canvas, but different panels for different pages. So each panel has its own UI elements for different pages.
What could be the best option for my app?
If somebody discuss advantages and disadvantages for different options, it would be great.
I mostly use combination of 1 and 3 or only 3.
Passing data between different scenes is more difficult than passing data between gameobjects within the same scene (i.e. requires static members/persistent data/gameobjects that won't be destroyed when the scene is being unloaded).
In single scene options, handling the game state becomes more complex (i.e. which gameobjects are active and visible in different phases of game flow).
It's easier to make transition effects with single scene option especially if two views are visible at the same time.
I'd go with number 2 because you can just deactivate irrelevant canvases and draw only those currently active. This will be more performant than option 3 and afford smoother transitions than option 1. If you're running out of memory then split the scene in half, etc. With only 8 pages your state machine doesn't sound like it would be too difficult to manage.

How many uGUI elements is too many on iOS?

According to this page, https://docs.unity3d.com/Manual/iphone-basic.html, too many UnityGUI elements is considered bad, but what is too many if my game runs entirely on the canvas? At the moment, my UI will contain about 100 objects, most are buttons and 80 of the objects, use full or portions of 3 textures to display the objects.
Does this mean that uGUI cannot or should not be used for iOS games?
That post is talking about something totally different and you are confusing yourself with uGUI and UnityGUI/IMGUI.
UnityGUI/IMGUI is an old UI System. That's what the article is talking about. Don't use it. I've been warning new users about that too due and they use it due to old tutorials they are following.
The only time you should use this is when you are writing an Editor script to test your game in the Editor but this should never be deployed to your mobile device or used as a standalone build.
How to know when you are using UnityGUI/IMGUI or which tutorials to avoid? When you see OnGUI() anywhere in the code, then stop.
The latest UI System in Unity is simply called uGUI. I don't know if the name has changed but this was the original name when it came out. It is only available from Unity 4.6 and above. You can find this from the UnityEngine.UI; namespace.
This is the link you should be reading for the new UI and here for UI tutorials.
Does this mean that uGUI cannot or should not be used for iOS games?
uGUI should be used for all your UI work.Again, I am not talking about the UI from the article. I am talking about the UI from the UnityEngine.UI; namespace.
my UI will contain about 100 objects, most are buttons and 80 of the
objects
uGUI uses Canvas to drive the UI and they are parent GameObject of UI components.. You may want to separate them into different Canvas. For example, MainMenu Canvas, PauseMenu Canvas, GamePlay Canvas.... Under each Canvas, you can then have your components such as Buttons and Texts.
When you are on the main menu, you enable the MainMenu Canvas and disable the rest. You can do this for your other Canvas in your scene depending on the mode of your game. I can't think of any scenario where you need 80 UI components at the-same time, on the scene. You must separate them.

How to make a simple 3d object viewer component for already build native iOS app?

Several years ago I was curious about creating some objects (spoon, ball, tv, ...) in 3d modeling program, export the textures, and then have a screen in iOS app, that can open one object at a time with a possibility to rotate and zoom it. This seemed quite basic and most used case but I didn't find any simple and ready to use solutions/libraries/plugins, just raw OpenGL ES (GlKit), so I refused to use it, as it would require too much knowledge and time as I haven't done any 3d stuff before and my primary work is not related with 3d.
There are also Unity and Cocos3d engines, and it looks like they allow to extend the code by using iOS plugins (xibs/storyboards, navigation with view controllers and etc), but this means you have to make your app project as Unity/Cocos3d first, and only then add your usual UIKit stuff as a plugin. Now that is not acceptable because the project should be written using UIKit first, and I expect to add 3d viewing stuff as a separate component that encapsulates all the necessary stuff inside it as a black box, because I don't want to mess my project up, as this 3d stuff is an optional feature.
Now, after several years I'v searched for the thing again looking for simple 3d viewing plugins/solutions for UIKit, but the situation is pretty much the same imho. I saw iOS8 there will add Scene Kit, but I'm not sure will it be something close to what I expect. So, still I'm not sure is there any solution that would require minimum time efforts, or is OpenGL ES the best solution for this need.
Check out the CC3DemoMultiScene demo app in the latest version of Cocos3D. It demonstrates how to include a Cocos3D scene in a standard UIKit storyboard, and to have the GL view only a component of a larger UIView.

Steps for redesigning an iPad app for Mac OS X?

What commonly expected user-visible design idioms need to change from an iPad app to a Mac app for an app, that is to provide basically identical functionality, to seem at least reasonably Mac OS X native?
Some of these changes, commonly expected by users, might include:
Move the Settings button and Info button to Menu selections for Preferences... and About...
Move the Settings view and Info view or popover to their own independent Preferences and About windows instead of being views in the main window.
Add some menu items and menu keys for commonly used buttons (like the forward and back buttons in a browser).
Support arrow keys for scrolling any custom view items.
Support mouse-over for help popups or dynamic menus.
If the app supports "documents", allow more than one document to be open at a time, each in their own windows.
What else? What's the minimum change required for a simple generic 2D game?
Added clarifications:
Note that I do not consider re-coding similar UI classes to NS classes (for instance UIButtons to NSButtons), with similar look, positions and behaviors, to be a significant change. Those changes are pretty much invisible to the user.
The goal is to change as little as possible so that a user who purchased app X to do Y on an iPad might purchase app X to do Y on their Mac, as a Mac application, but with as close to zero learning curve as possible. But it seems that some changes need to be made, or the app would not seem to be a Mac app (for instance, a missing About... menu item would seem a bit strange.)

You've gone off the rails right there. Consider adding this to your list:
Forget everything you know about how your iPad app works. Step back and consider that a user's interaction with and expectation of a desktop application are very different from those of a tablet. Re-think what you're able to do and what the user will want to do with a faster processor, more power, significantly more available storage, less mobility, much faster text entry, and a different user interface model.
We are in the same boat and faced the same question.
Our conclusion is to start with a "fresh" real application for Mac and make it look similar, i.e. using the same or similar UI components and graphics. The app should be otherwise developed as if there was no iPad version.
First, there will be many users that don't have the iPad version. Those users expect a full-blown Mac application and it doesn't make sense to make it feel iPad in any way.
Second, users coming from the iPad version will feel ripped of if the Mac app is just a pure clone of the iPad version with no added value. Think of the first transitions from iPhone to iPad - paying again for nothing but pure upscales is frustrating and might harm your business in the long run.
Starting out designing a fresh streamlined UI and then think of what you can reuse and make similar. Functionality may differ in one direction or the other. Your model code should work in all places anyway.
Not exactly an answer to your question, but take a look at Chameleon. It's essentially a port of UIKit to the Mac. It was created by The Icon Factory to make it easy for developers to port their iOS apps to the Mac. IIRC Twitterific was ported to the Mac using Chameleon.
So here's what I did to create a Mac app from an iPad app, and have it accepted into the Mac App store.
Ignored the suggestions to completely redesign the app (users reasonably liked the iPad design).
Create a Mac app project and include a branch of all the iOS source code.
Manually recode all the UI elements with their corresponding NS elements. Resize them to Mac UI guideline sizes. Check that they all show up in some reasonable place when the main window is resized. Deleted iPad only delegates, such as rotation handlers, etc. This resulted in completely new view controller code, but almost all the code was just a parallel translation of the other paradigm.
Set the view coordinates to flipped so the Y coordinates won't have to be recalculated for any Core Graphics drawing routines. (The Model and CG drawing code pretty much ported straight over without change, except for scale factors for window size, and such.)
Remove settings and help views from the main window view controller(s). Implement a Preferences window xib and a Help window xib, and put all the settings and pref views and controls there. Add one more top level controller to show/hide the 3 windows.
Add some menu selections with hotkeys for equivalent UIButton actions that a user might want to hit without reaching for the mouse/trackpad.
Add a credits.html file.
Add an outline shape and transparency masks to the icon design, and stuff into an .icns file.
Pad the one window screen shot out to the much larger required size.
