And thank you for taking the time to help us improve the quality of Unity Documentation. If an asset can be found at pathit is returned with type Totherwise returns null. If the file at path is of a type that cannot be converted to Talso returns null. The path is relative to any folder named Resources inside the Assets folder of your project. More than one Resources folder can be used.
The path does not need to include Assets and Resources in the string, for example loading a GameObject at Assets path Shotgun.
If you have multiple Resources folders you cannot duplicate the use of an asset name. Note: Extensions must be omitted. Note: All asset names and paths in Unity use forward slashes, paths using backslashes will not work. Returns the asset at path if it can be found, otherwise returns null. If the type parameter is specified, only objects of this type are returned. The path is relative to any Resources folder inside the Assets folder of your project, extensions must be omitted.

Publication Date: Path to the target resource to load.In some situations, it is useful to make an asset available to a project without loading it in as part of a scene A Scene contains the environments and menus of your game.
Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info See in Glossary. Furthermore, you may even want to load assets from a separate file or URL to reduce initial download time or allow for interchangeable game content. Unity supports Resource Folders in the project to allow content to be supplied in the main game file yet not be loaded until requested. You can also create Asset Bundles.
These are files completely separate from the main game file which contain assets to be accessed by the game on demand from a file or URL.Naruto neglected by family fanfiction emperor
An Asset Bundle is an external collection of assets. You can have many Asset Bundles and therefore many different external collections of assets. These files exist outside of the built Unity player, usually sitting on a web server for end-users to access dynamically.Controlling single cluster dynamics at the nanoscale
To build an Asset Bundle, you call BuildPipeline. BuildAssetBundles from inside an Editor script. In the arguments, you specify an array of Objects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more.
More info See in Glossary to be included in the built file, along with some other options. This will build a file that you can later load dynamically in the runtime by using AssetBundle. Resource Folders are collections of assets that are included in the built Unity player, but are not necessarily linked to any GameObject in the Inspector A Unity window that displays information about the currently selected GameObject, asset or project settings, alowing you to inspect and edit the values.
You can have multiple Resource Folders organized differently in your Project. Whenever you want to load an asset from one of these folders, you call Resources.
Loading Resources at Runtime
All assets found in the Resources folders and their dependencies See in Glossary are stored in a file called resources. If an asset is already used by another level it is stored in the.
Only assets that are in the Resources folder can be accessed through Resources. For example a Material in the Resources folder might reference a Texture outside of the Resources folder.
You can unload resources of an AssetBundle by calling AssetBundle. If you pass true for the unloadAllLoadedObjects parameter, both the objects held internally by the AssetBundle and the ones loaded from the AssetBundle using AssetBundle.
LoadAsset will be destroyed and memory used by the bundle will be released.In this article, I will explain how to load image at runtime in unity scene. I will cover following ways by which you can add image at runtime in unity.
I have added RawImage game object in the scene. Use Resources. Load method to load image from resources folder. First, copy your image in the Resources folder. You can find the image used in this article over here. First convert the image into sprite in unity editor, then you can load that at runtime just like textures.
Use WWW class for loading image from any local directory. Make sure the file path is correct. Image can also be loaded from asset bundles.
Please refer my article Load Asset Bundle in Unity for details. Hope you enjoyed reading this article. Please post your comments for queries and feedback.Unity 3D - Load audio from a file!

Let me explain the problem in details: I want to import an image at runtime to be a texture. And the image is from other location on the disk not in Unity project folder.
I am using the EditorUtility. OpenFilePanel to get the path right now. But I do not know which function can be used to load the image via the path. Could anybody please tell me how to do this? Thanks a lot! Joined: Mar 28, Posts: 2, If you are also looking for a document browser to let the user select a file, I believe there is one somewhere on the wiki.

Furthermore, an image target can be created from a locally stored image file and added to an empty dataset to generate a trackable for your AR content, all during the application runtime.
To access and modify your targets at runtime, your AR application should access target attributes programmatically using the Trackable class of the Vuforia API. This function is called when the SDK is finished with a camera frame and it is safe to do a reconfiguration.
Applications can use multiple Device Databases at the same time. Targets in databases that are loaded but not activated are not counted as active targets. If you use Object Targets with other target types, you can use a maximum of 20 Object Targets and 80 of the other target types. Databases can be created using the Vuforia Target Manager or by loading image files directly. The following example allows you to retrieve an image file from a local storage and attach it to a RuntimeImageSource.
Hereafter, the runtime image can be loaded into an empty dataset. In the example, the application creates and loads two target databases, and then activates one of the databases. The following section provides instructions and code samples showing how to load a Device Database in an Android project. NOTE: You must do a clean build after the assets have been modified in the directory. Otherwise, the packager does not include the new assets in your app installer APK package. Image targets that are detected and tracked in the current frame can be accessed through a list of TrackableResult objects.
In the following example, the code does the following:. This section provides sample code showing how to access, create and destroy Virtual Buttons programmatically at runtime.
You can request the virtual button state from active targets in the scene by iterating through the button child objects. The following code snipped provides an example of this action.
To create or destroy Virtual uttons dynamically, you should make these changes after the tracker updates the state. After the tracker delivers a valid state, the Vuforia SDK calls this registered callback on each frame, as illustrated in the following code snippet:.
The following function executes the actual toggle of the button. This function is called for each button in the list that is created in the previous code fragment. The following code fragment shows how to create a new button and how an existing button can be accessed or destroyed.By this point you should understand the concept of Prefabs at a fundamental level. Prefabs come in very handy when you want to instantiate complicated GameObjects at runtime.
The alternative to instantiating Prefabs is to create GameObjects from scratch using code. Instantiating Prefabs has many advantages over the alternative approach:.
If you execute that code, you will see an entire brick wall is created when you enter Play mode. There are two lines relevant to the functionality of each individual brick: the CreatePrimitive line, and the AddComponent line.
Not so bad right now, but each of our bricks is un-textured. Every additional action to want to perform on the brick, like changing the texture, the friction, or the Rigidbody massis an extra line. If you create a Prefab and perform all your setup before-hand, you use one line of code to perform the creation and setup of each brick. This relieves you from maintaining and changing a lot of code when you decide you want to make changes.
With a Prefab, you just make your changes and Play. No code alterations required. This is not only very clean but also very reusable. There is nothing saying we are instantiating a cube or that it must contain a rigidbody. All of this is defined in the Prefab and can be quickly created in the Editor. When you select the empty GameObject that contains the script, the Brick variable will be visible in the inspector. This is a workflow pattern that can be used over and over again in Unity.
In the beginning you might wonder why this is so much better, because the script creating the cube from code is only 2 lines longer. But because you are using a Prefab now, you can adjust the Prefab in seconds. Want to change the mass of all those instances? Adjust the Rigidbody in the Prefab only once. Want to use a different Material for all the instances?
Drag the Material onto the Prefab only once. Want to change friction? Want to add a Particle System to all those boxes? Add a child to the Prefab only once. While it would be possible to build a rocket GameObject completely from code, adding Components manually and setting properties, it is far easier to instantiate a Prefab. After instantiating the Prefab you can also modify any properties of the instantiated object e.
Aside from being easier to use, you can update the prefab later on. You can do that later. As soon as you add the trail as a child GameObject to the Prefab, all your instantiated rockets will have particle trails. And lastly, you can quickly tweak the properties of the rocket Prefab in the Inspector, making it far easier to fine-tune your game.
