Android SDK Tools Installation for unity3d Simple Guide. When you are building an Android app in Unity, make sure you arranged the Android Software Development Kit (SDK) just before you build and play any code on your Android device. Install JDK Before SDK In case you don’t have a Java Developer Kit (JDK) it is important to download one from here before you can set up the Android SDK. Install Android SDK To develop an Android app you'll want to set up the Android SDK, and this can be downloaded from here . I installed the SDK to c:\android-sdk Enabling USB Debugging Image source kingroot It is important to enable USB debugging with the device.

Unity upgrades come with more features and ease where it also bring problem for some indie as well as pro developer, Like this "profiler" error.

The error is: SUCCEEDED ( hr ) rc . right == m_GfxWindow -> GetWidth () && rc . bottom == m_GfxWindow -> GetHeight ()   it works in most cases, but not all time. Solutions From different users: I found that closing and re-opening unity fixed the error (or at least stopped it from showing up in the footer). I re-started Unity and the message is gone. I tried run unity as admin and the problem is solved  I had the same problem. I was using two screen and it was solved when I turned off one of them.  see also: NullReferenceException: Object reference not set to an instance of an object Unity’s latest Facebook build target finally available as a Developer Beta Mode

NullReferenceException: Object reference not set to an instance of an object This Exception occurs in Unity whenever you try to access a variable that is not initialized or does not refer to any object. For example when you create a GameObject variable in a script, by default it does not refer to anything. To assign a value to that GameObject variable you have to make it equal to some value before using it. Example: <?phpPublic GameObject myObject; void Awake(){ myObject = someObject; } You can either set myObject in code as shownin example above, or through inspector as it is a public object (refer to image below). This exception can also occur while trying to instantiate and object for same reason. For Example: Instantiate(myObject,new Vector3.zero,Quaternion.Identity); This might give NullReferenceException if myObject variable refers to nothing. This Exception will also occur if you are trying to access a member function of uninitialized object. For Example...

We know that developing android apps and working with AdColony SDK to show video ads gives you problem. The problem we found usually it keeps downloading video ads and save them on the device. I found the comment from the person from Adcolony, He says AdColony does cache our assets to the device - both for quality (instant loading advertisements) as well as reusability. Many assets are shared across multiple campaigns and in the case that a duplicate advertisement is served it saves you from re-downloading the same assets. Each device has a specific memory class (or app specific memory limit) that we will not exceed, and we also purge old and unused assets occasionally to keep the size down. While it is possible to programmatically clear your app's data cache, we do not recommend this as it may lead to redundant downloads and unnecessary data usage. Please feel free to contact us further at support@adcolony.com. Solution: Your video is stored in the application dat...

Now a days word reskin is everywhere in game developers field, you can hear this word mostly on freelancers sites like odesk, freelancer, elance etc. Reskinning is a great and ideal way for startup guys and also for me :) This is like altering the appearance of the video game (graphics, menu’s, in-game characters, background scenes, and so on) and also the sounds and tunes hanging around while maintaining the definite gameplay almost the same. Images, sounds and audio are together termed as game or app resources, Reskinning is actually a procedure where app developers don't need to develop a game from the beginning. You get a premade source-code of an app/ game and alter its layout entirely, so it can have an exciting new look. There are lots of benefits of reskinning premade codes like, cutting developing time, growing income, reducing issues and many others. Today I am going to show the simple way I used to earn $300 in 4 days with odesk and reskinning. ...

Sometimes it happens that you try to open unity editor but it goes bug report screen or crash. By default, Unity always loads up the last project that you edited. 1. You can skip this bug screen by holding down "Alt" immediately after unity starts, and you'll get an option to select a different project or start a new project. 2. If this doesn't solve the error you should check you drivers this happens with lots of users reported. Start > Run > "DXDIAG" and hit enter Uninstalling the HID drivers helped many users. 3. Renaming the project which is crashing also solve, but start project as a blank. 4. Uninstall any third party application you installed for unity. If the problem still continue please contact Unity Support: support@unity3d.com or report a bug. Am I missing something? Suggest me in comments!

The way to remove game object you want is simple easy what you need to add is the piece of function and your object. The public static function Destroy() is a key its Removes a gameobject, component or asset.  reference Examples: // Kills the game object Destroy (gameObject); // Removes this script instance from the game object Destroy (this); // Removes the rigidbody from the game object Destroy (rigidbody); // Kills the game object in 5 seconds after loading the object Destroy (gameObject, 5); // When the user presses Ctrl, it will remove the script // named FooScript from the game object function Update () { if ( Input.GetButton ("Fire1") && GetComponent (FooScript)) Destroy (GetComponent (FooScript)); }

Have a look at the complete guide and source of slender  by  alucardj . This what he said in unity forum. +unity3DIY Finally, I have given up and am now making my scripts available for download. If you need to know how these scripts work, watch all my videos. If you want to just get the game running, follow the videos starting at 79 _ Slender the Examination 6 months after I started using Unity 3D I wrote a little 'guide' on Unity answers to a question about Slender. That turned out to be crazy, I never expected the amount of traffic and questions that was to come after that. Now ignorance is no excuse but i was naive, I didn't even know what a Slender was! The first time I answered a question for how to pick up papers, I thought it was for a RPG quest or a school project. When the how can the player detect when the enemy is visible questions came up, I was thinking about Doctor Who (if you know what I mean, you'll know. I want to do that one myself!). In...

Testability is a crucial element of every software product – game development is not an exclusion. To allow testability, all of the components must be independent and testable in separation. Once we wish to test something in isolation this means that we wish to decouple it. Reduce coupling is everything we want. It's so simple to implant hidden dependencies to your game and it's really so difficult to break them. This article can help you realize loose coupling and dependency injection within project in Unity, using the example project on github . you should join us on  +unity3DIY

Avoiding your objects from passing with each other is really tricky especially for fast moving objects like bullets and Prevent colliders. Today we made tutorial and script for you to show how to prevent colliders  from passing through each other. The best way to make sure that you detect all collision is to use Raycasting instead of depending on the physics simulation. This is helpful for bullets or small objects, but will likely not provide great results for large objects.  Below answer is from stackoverflow Collision with fast-moving objects is always a problem. A good way to ensure that you detect all collision is to use Raycasting instead of relying on the physics simulation. This works well for bullets or small objects, but will not produce good results for large objects. http://unity3d.com/support/documentation/ScriptReference/Physics.Raycast.html Pseudo-codeish (I don't have code-completion here and a poor memory): void FixedUpdate() { Ve...
