Description

Abstract base class for custom Asset importers.

Scripted importers are scripts that are associated with specific file extensions. They are invoked by Unity's Asset pipeline to convert the contents of associated files into Assets.

Use the ScriptedImporterAttribute class to register custom importers with the Asset pipeline.

#pragma strict
@ScriptedImporter(1, "cube")
public class CubeImporter extends ScriptedImporter {
	public var m_Scale: float = 1;
	public override function OnImportAsset(ctx: AssetImportContext) {
		var cube: var = GameObject.CreatePrimitive(PrimitiveType.Cube);
		var position: var = JsonUtility.FromJson.<Vector3>(File.ReadAllText(ctx.assetPath));
		cube.transform.position = position;
		cube.transform.localScale = new Vector3(m_Scale, m_Scale, m_Scale);
		// (Only the 'Main Asset' is elligible to become a Prefab.)
		ctx.AddObjectToAsset("main obj", cube);
		ctx.SetMainObject(cube);
		var material: var = new Material(Shader.Find("Standard"));
		material.color = Color.red;
		// Assets must be assigned a unique identifier string consistent across imports
		ctx.AddObjectToAsset("my Material", material);
		// Assets that are not passed into the context as import outputs must be destroyed
		var tempMesh: var = new Mesh();
		DestroyImmediate(tempMesh);

cube.transform.position = position; cube.transform.localScale = new Vector3(m_Scale, m_Scale, m_Scale);

// 'cube' is a a GameObject and will be automatically converted into a prefab // (Only the 'Main Asset' is elligible to become a Prefab.) ctx.AddObjectToAsset("main obj", cube); ctx.SetMainObject(cube);

Public Methods

OnImportAssetThis method must by overriden by the derived class and is called by the Asset pipeline to import files.

Inherited Members

Properties

assetBundleNameGet or set the AssetBundle name.
assetBundleVariantGet or set the AssetBundle variant.
assetPathThe path name of the asset for this importer. (Read Only)
importSettingsMissingThe value is true when no meta file is provided with the imported asset.
userDataGet or set any user data.
hideFlagsShould the object be hidden, saved with the scene or modifiable by the user?
nameThe name of the object.

Public Methods

AddRemapMap a sub-asset from an imported asset (such as an FBX file) to an external Asset of the same type.
GetExternalObjectMapGets a copy of the external object map used by the AssetImporter.
RemoveRemapRemoves an item from the map of external objects.
SaveAndReimportSave asset importer settings if asset importer is dirty.
SetAssetBundleNameAndVariantSet the AssetBundle name and variant.
GetInstanceIDReturns the instance id of the object.
ToStringReturns the name of the GameObject.

Static Methods

GetAtPathRetrieves the asset importer for the asset at path.
DestroyRemoves a gameobject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadMakes the object target not be destroyed automatically when loading a new scene.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsOfTypeReturns a list of all active loaded objects of Type type.
InstantiateClones the object original and returns the clone.

Operators

boolDoes 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.
