Class for handling 2D texture arrays.
Modern graphics APIs (e.g. D3D10 and later, OpenGL ES 3.0 and later, Metal etc.) support "texture arrays", which is an array of same size & format textures.
From the shader side, they are treated as a single resource, and sampling them needs an extra coordinate that indicates which array element to sample from.
Typically texture arrays are useful as an alternative for texture atlases, or in other cases where objects use a set of same-sized textures (e.g. terrains).
Currently in Unity texture arrays do not have an import pipeline for them, and must be created from code, either at runtime or in editor scripts.
Using Graphics.CopyTexture is useful for fast copying of pixel data from regular 2D textures into elements of a texture array. From editor scripts,
a common way of creating serialized texture array is to create it, fill with data (either via Graphics.CopyTexture from regular 2D textures, or via SetPixels or
SetPixels32) and save it as an asset via AssetDatabase.CreateAsset.
Note that not all platforms and GPUs support texture arrays; for example Direct3D9 and OpenGL ES 2.0 do not. Use SystemInfo.supports2DArrayTextures to check. Also, this class does not support Texture2DArray creation with a Crunch compression TextureFormat.
| allSlices | Read Only. This property is used as a parameter in some overloads of the CommandBuffer.Blit, Graphics.Blit, CommandBuffer.SetRenderTarget, and Graphics.SetRenderTarget methods to indicate that all texture array slices are bound. The value of this property is -1. |
| depth | Number of elements in a texture array (Read Only). |
| format | Texture format (Read Only). |
| isReadable | Returns true if this texture array is Read/Write Enabled; otherwise returns false. For dynamic textures created from script, always returns true. |
| Texture2DArray | Create a new texture array. |
| Apply | Actually apply all previous SetPixels changes. |
| GetPixelData | Gets raw data from a Texture for reading or writing. |
| GetPixels | Retrieves a copy of the pixel color data for a given mip level of a given slice. The colors are represented by Color structs. |
| GetPixels32 | Retrieves a copy of the pixel color data for a given slice, at a given mip level. The colors are represented by lower-precision Color32 structs. |
| SetPixelData | Set pixel values from raw preformatted data. |
| SetPixels | Set pixel colors for the whole mip level. |
| SetPixels32 | Set pixel colors for the whole mip level. |
| allowThreadedTextureCreation | Allow Unity internals to perform Texture creation on any thread (rather than the dedicated render thread). |
| currentTextureMemory | The amount of memory that all Textures in the scene use. |
| desiredTextureMemory | The total size of the Textures, in bytes, that Unity loads if there were no other constraints. Before Unity loads any Textures, it applies the memory budget which reduces the loaded Texture resolution if the Texture sizes exceed its value. The `desiredTextureMemory` value takes into account the mipmap levels that Unity has requested or that you have set manually.For example, if Unity does not load a Texture at full resolution because it is far away or its requested mipmap level is greater than 0, Unity reduces the `desiredTextureMemory` value to match the total memory needed.The `desiredTextureMemory` value can be greater than the `targetTextureMemory` value. |
| GenerateAllMips | Can be used with Texture constructors that take a mip count to indicate that all mips should be generated. The value of this field is -1. |
| nonStreamingTextureCount | The number of non-streaming Textures in the scene. This includes instances of Texture2D and CubeMap Textures. This does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| nonStreamingTextureMemory | The amount of memory Unity allocates for non-streaming Textures in the scene. This only includes instances of Texture2D and CubeMap Textures. This does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| streamingMipmapUploadCount | How many times has a Texture been uploaded due to Texture mipmap streaming. |
| streamingRendererCount | Number of renderers registered with the Texture streaming system. |
| streamingTextureCount | Number of streaming Textures. |
| streamingTextureDiscardUnusedMips | This property forces the streaming Texture system to discard all unused mipmaps instead of caching them until the Texture memory budget is exceeded. This is useful when you profile or write tests to keep a predictable set of Textures in memory. |
| streamingTextureForceLoadAll | Force streaming Textures to load all mipmap levels. |
| streamingTextureLoadingCount | Number of streaming Textures with mipmaps currently loading. |
| streamingTexturePendingLoadCount | Number of streaming Textures with outstanding mipmaps to be loaded. |
| targetTextureMemory | The total amount of Texture memory that Unity allocates to the Textures in the scene after it applies the memory budget and finishes loading Textures. `targetTextureMemory`also takes mipmap streaming settings into account. This value only includes instances of Texture2D and CubeMap Textures. It does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| totalTextureMemory | The total amount of Texture memory that Unity would use if it loads all Textures at mipmap level 0.This is a theoretical value that does not take into account any input from the streaming system or any other input, for example when you set the`Texture2D.requestedMipmapLevel` manually.To see a Texture memory value that takes inputs into account, use `desiredTextureMemory`.`totalTextureMemory` only includes instances of Texture2D and CubeMap Textures. It does not include any other Texture types, or 2D and CubeMap Textures that Unity creates internally. |
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
| name | The name of the object. |
| anisoLevel | Defines the anisotropic filtering level of the Texture. |
| dimension | Dimensionality (type) of the Texture (Read Only). |
| filterMode | Filtering mode of the Texture. |
| graphicsFormat | Returns the GraphicsFormat format or color format of a Texture object. |
| height | Height of the Texture in pixels. (Read Only) |
| imageContentsHash | The hash value of the Texture. |
| isReadable | Returns true if the Read/Write Enabled checkbox was checked when the Texture was imported; otherwise returns false. For a dynamic Texture created from script, always returns true. For additional information, see TextureImporter.isReadable. |
| mipMapBias | The mipmap bias of the Texture. |
| mipmapCount | How many mipmap levels are in this Texture (Read Only). |
| updateCount | This counter is incremented when the Texture is updated. |
| width | Width of the Texture in pixels. (Read Only) |
| wrapMode | Texture coordinate wrapping mode. |
| wrapModeU | Texture U coordinate wrapping mode. |
| wrapModeV | Texture V coordinate wrapping mode. |
| wrapModeW | Texture W coordinate wrapping mode for Texture3D. |
| GetInstanceID | Gets the instance ID of the object. |
| ToString | Returns the name of the object. |
| GetNativeTexturePtr | Retrieve a native (underlying graphics API) pointer to the Texture resource. |
| IncrementUpdateCount | Increment the update counter. |
| Destroy | Removes a GameObject, component or asset. |
| DestroyImmediate | Destroys the object obj immediately. You are strongly recommended to use Destroy instead. |
| DontDestroyOnLoad | Do not destroy the target Object when loading a new Scene. |
| FindObjectOfType | Returns the first active loaded object of Type type. |
| FindObjectsOfType | Gets a list of all loaded objects of Type type. |
| Instantiate | Clones the object original and returns the clone. |
| SetGlobalAnisotropicFilteringLimits | Sets Anisotropic limits. |
| SetStreamingTextureMaterialDebugProperties | This function sets mipmap streaming debug properties on any materials that use this Texture through the mipmap streaming system. |
| bool | Does the object exist? |
| operator != | Compares if two objects refer to a different object. |
| operator == | Compares two object references to see if they refer to the same object. |
