  • Android Swipe In Unity 3D World with AR

    - by Christian
    I am working on an AR application using Unity3D and the Vuforia SDK for Android. The way the application works is a when the designated image(a frame marker in our case) is recognized by the camera, a 3D island is rendered at that spot. Currently I am able to detect when/which objects are touched on the model by raycasting. I also am able to successfully detect a swipe using this code: if (Input.touchCount > 0) { Touch touch = Input.touches[0]; switch (touch.phase) { case TouchPhase.Began: couldBeSwipe = true; startPos = touch.position; startTime = Time.time; break; case TouchPhase.Moved: if (Mathf.Abs(touch.position.y - startPos.y) > comfortZoneY) { couldBeSwipe = false; } //track points here for raycast if it is swipe break; case TouchPhase.Stationary: couldBeSwipe = false; break; case TouchPhase.Ended: float swipeTime = Time.time - startTime; float swipeDist = (touch.position - startPos).magnitude; if (couldBeSwipe && (swipeTime < maxSwipeTime) && (swipeDist > minSwipeDist)) { // It's a swiiiiiiiiiiiipe! float swipeDirection = Mathf.Sign(touch.position.y - startPos.y); // Do something here in reaction to the swipe. swipeCounter.IncrementCounter(); } break; } touchInfo.SetTouchInfo (Time.time-startTime,(touch.position-startPos).magnitude,Mathf.Abs (touch.position.y-startPos.y)); } Thanks to andeeeee for the logic. But I want to have some interaction in the 3D world based on the swipe on the screen. I.E. If the user swipes over unoccluded enemies, they die. My first thought was to track all the points in the moved TouchPhase, and then if it is a swipe raycast into all those points and kill any enemy that is hit. Is there a better way to do this? What is the best approach? Thanks for the help!

  • Good mobile oriented GWT widget library alternatives

    - by Michael Donohue
    I've been developing a travel planning site - tripgrep.com - which is built on appengine, GWT and smartgwt, among other technologies. It is still early days, and the site is now working well on my development environment, which is either a windows or mac computer. However, I am frequently talking up the website to my friends when we are at a bar or other venue, so I am standing there while they try to access the site via an iPhone, Android or Blackberry - I've witnessed all three. It has been painfully obvious that the browser based frontend takes a long time to download on a mobile device. I am pretty sure this is because of the javascript download for SmartGWT. So, I would like to look at alternatives to SmartGWT. What I like about SmartGWT is that it has a reasonable look and feel out of the box - I don't need to learn any design or css and it has an office application look. This is considerably better than the GWT built-in widgets, which just get a blue border. The better look-and-feel is why I went with SmartGWT early on. However, the slow load times are killing me on these mobile demos. So now I want a fast loading widget alternative that has good look-and-feel out of the box. The features I care about are: tabs, good form layout, Google maps API integration, grid data viewing. If those are all available in a library that loads quickly on a mobile device, then that's the library I want.

  • Multi-Resolution Mobile Development

    - by user2186302
    I'm about to start development on my first game for mobile phone (I already have a flash prototype completed so it's jsut a matter of "porting" it to mobile and fixing up the code) and plan on hopefully being able to get the game working on iphones and most android devices. I am using Haxe along with OpenFL and HaxeFlixel for development. My question is: What resolution should I design the game in initially and/or what is the best way to develop a game for multiple resolutions. I have found multiple different methods, the best, in my opinion, being strategy 3 on this page: http://wiki.starling-framework.org/manual/multi-resolution_development. However I have some questions about this. First, what would the best base resolution to use be, the guide suggests 240*320 which seems alright to me, although if I chose to use pixel graphics as I most probably will given I'm using HaxeFlixel, I'm not sure if they'll look too blocky on larger screens which I'm not even sure is a problem as it might still look alright. (Honestly, not sure about that and if anyone has any examples of games that use this method and look nice). Finally, please feel free to share whatever methods you use and think is best. For example, HaxeFlixel has a scaling feature that scales the game to fit the exact screen size, but I'm afraid that would lead to blurry and improperly scaled graphics since it would scale by non-integers. But, I'm not sure how noticeable a problem that may or may not be. Although from experience I'm pretty sure it won't look nice and currently I do not think I'm going to go for this option. So, I would really appreciate any help on this subject. Thank you in advance.

  • Is it wrong to tell mobile users to view a site on their computer?

    - by betamax
    I am creating a web application that doesn't work correctly on mobile. I don't want to make it work on mobile because I would rather mobile users have a fully integrated experience and not have to use the web version. This mobile version will be released at a later date based on reaction to the initial web-based version. So, my question is: Is it wrong to not allow mobile users to use the site and instead show them some sort of splash screen telling them to come back to the site on a computer?

  • Need new method for linking to native mapping from mobile web app

    - by Carter
    My mobile web apps use a map button which automatically starts the mapping features of Android and iPhone by simply linking to http://maps.google.com/maps?q=New+York. iOs 6 comes out, the links stop working, because Apple wants us to use "maps.APPLE.com". Turns out ANYTHING you send to "maps.apple.com" gets forwarded to "maps.google.com". So now I have to specially detect iOs 6 and swap out links just so Apple can forward everything back to Google anyway. Is there a clean way to open the device/native mapping app from a mobile web app that works on Android, iOs 6, and iOs pre-6, since iOs 6 nerfed it? Recently updated documentation on Apple dev site... http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html#//apple_ref/doc/uid/TP40007894-SW1 Both these links go to the same place http://maps.google.com/maps?q=New+York http://maps.apple.com/maps?q=New+York

  • A Visual Studio tool eliminating the need to rewrite for web and mobile

    - by Visual WebGui
    We have already covered the BYOD requirements that an application developer is faced with, in an earlier blog entry ( How to Bring Your Own Device (BYOD) to a .NET application ). In that entry we emphasized the fact that application developers will need to prepare their applications for serving multiple types of devices on multiple platforms, ranging from the smallest mobile devices up to and beyond the largest desktop devices. The experts prediction is that in the near future we will see that the...(read more)

  • Extremely large spike in traffic on the 1st - 4th of every month from mobile browsers

    - by wsanville
    I've noticed that on the 1st - 4th of the recent months (since January), several sites I maintain are getting thousands of requests from mobile browsers, whereas throughout the rest of the month, the numbers are in the single or double digits. Has anybody else noticed this sort of behavior? I don't have the exact user agents logged, but my analysis software (WebTrends) reports the traffic as mostly iPhone/iPad/iPod, Android, and Blackberry.

  • Disable mobile page redirection for SharePoint 2013

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information SharePoint 2013 (foundation too), detects requests from mobile devices and automatically changes the uRL of the requested non mobile page to its mobile substitute. This logic is now built into SPRequestModule. The mobile view is pretty damned amazing. Even though the set of pages for mobile access is completely different, SharePoint has an entirely separate set of controls for the mobile pages. These are in the Microsoft.SharePoint.MobileControls namespace which inherit from Microsoft ASP.NET controls in the System.Web.UI.MobileControls namespace. These Mobile pages can even use mobile Web Part adapters to mimic the behavior of webparts on mobile webpart pages. Read full article ....

  • Is my project a web site or a mobile app?

    - by Evik James
    I am a web developer. I have been developing web sites professionally for 15+ years using ColdFusion, SQL Server, and jQuery. I am doing a project for a client that uses the above technologies. The site has a mobile facet too. For that, I am using jQuery Mobile. The site enables retail store personnel to gather a store customer's preferences using any smart phone or tablet. The store personnel just needs to access a special link via a QR code and a login. Anyone can easily access the site from a PC's browser, too. Some sources suggest that mobile apps must be downloaded and installed using a third party, such as from Google, Amazon, or Apple. Others sources suggest that any information designed for use on mobile device is a mobile app. Regarding the site that is specifically designed for use by mobile devices that extensively uses jQuery Mobile, is this a "web site" or a "mobile app"? What is the "proper" description for this type of site? My customer insists that it is one and not the other. I insist that it is the other and not the one. Can you help me clarify this?

    I'd like to market my existing and/or upcoming mobile games. Specifically I want to have a "revenue sharing" agreement w/ the "marketing company"... i.e. I don't want to pay anything up front... and I'm will to give the marketing company a sizable chunk of the revenue (say up to 50%). Is a publisher the only entity that does this? Or do marketing companies exist that would be interested in this type of arrangement?

  • How to make a battle system in a mobile indie game more fun and engaging

    - by Matt Beckman
    I'm developing an indie game for mobile platforms, and part of the game involves a PvP battle system (where the target player is passive). My vision is simple: the active player can select a weapon/item, then attack/use, and display the calculated outcome. I have a concept for battle modifiers that affect stats to make it more interesting, but I'm not convinced the vision is complete. I've received some inspiration from the game engine that powers Modern War/Kingdom Age/Crime City, but I want more control to make it more fun. In those games, you don't have the option to select weapons or use items, and the "battling" screen is simply 3D eye candy. Since this will be an indie game, I won't be spending $$$ on a team of professional 3D artists/animators, so my edge needs to be different. How would you make a battle system like this more fun and engaging?

  • Development platform for 2D web and mobile games

    - by Robert Vella
    Is there a game development platform -- similar to Torque, or Unity -- which can be used to deploy 2D games on the following platforms: Web iOs Android Xbox Live Arcade (Preferred but not required) And which has an integrated or mature physics engine? Perhaps, even a built in editor? I've looked at the following possibilities but I've found something missing in each one. Of course in each case I may be guilty of misconception. Corona SDK (No web deployment, no windows support) Torque 2D (No web deployment) Flash + Flash Punk or Flixel (No native android deployment, and I'm not sure if it is stable on mobile platforms) Unity + SpriteManager2 (Not really optimised for 2D games, and I haven't seen enough advanced 2D examples -- like say platformers -- to really have any confidence in using it for something like this) Has anyone had any luck with this?

  • Typical text encoding+BOM, and EOL behavior on mobile devices

    - by Dan W
    Typical things to worry about when dealing with text are the BOM/signature, encoding, and the end of line (EOL) char/chars. I know that Windows often favours \r\n (CR+LF) and Mac/Linux favours \n (LF), but how about mobile devices such as the iPhone and Android? Do typical apps on those platforms favour one or the other? Also, which text encodings are mobiles most likely to use - UTF-8, iso-8859-1, or even Windows 1252 (or other default codepage) or maybe even UTF-16? And if they use UTF-8/16, are they likely to need (or require not having) a BOM/signature? What is the typical behavior here?

  • Cross platform mobile development VS Native Mobile Development: Present And Future.

    - by MobileDev123
    I just completed one year in Smart phone development, working on BlackBerry and Android and also developed one application exclusively targeted to nokia feature phones. And just a month ago I come to know about Titanium Appcelerator tool that enables cross platform development, but there are some developers who complain about it's sub-par functionalities. Even a little bit experience of mine says that developing in native environment rather than these cross platform tools will give you more advantages by giving a developer a chance to add more features with better performance. Do you have same experience? Or you find such cross development tools really useful regarding to advance functionality and performance? As porting (or co developing) same application to different mobile platform is common thing nowadays, what do you think will these cross platform tools evolve and force developers to get a hands on approach on them or majority will stick to the native development environment?
