InstantAssetEditorUtility.BuildAssetPacker

Parameters

Returns

bool Return true if asset packing is successful, return false if it fails.

Description

Pakcing assets from the specified folders to some bundles, and generate an InstantAssetTable to record asset information.

InstantAssetTable is saved in a single file with a name based on the folder path(e.g., InstantAssetTable_Assets_Test for assets in Assets/Test).

using UnityEngine;

public class BasicBuildExample
{
    [MenuItem("Tools/Build Instant Assets/Basic Directory Build")]
    public static void BuildAssetsFromDirectories()
    {
        string outputPath = "Assets/Output/InstantAssets";
        string[] directories = { 
            "Assets/Resources/UI", 
            "Assets/Resources/Models" 
        };
        int maxBundleSize = 1024 * 1024; // 1MB per bundle
        
        bool success = InstantAssetEditorUtility.BuildAssetPacker(
            outputPath,
            directories,
            maxBundleSize,
            BuildTarget.StandaloneWindows64);

        if (success)
        {
            Debug.Log("Instant Asset packages built successfully!");
        }
        else
        {
            Debug.LogError("Failed to build Instant Asset packages.");
        }
    }
}

Parameters

Returns

bool Return true if asset packing is successful, return false if it fails.

Description

Provides fine-grained control over the asset packing process, allowing custom alias table names, specific asset lists, and build options including compression settings.
