Prefab Loader

This class provides functionality to instantiate prefabs, keep track of multiple instances, and destroy them either immediately or after a delay. It also includes event-driven notifications for when instances are destroyed.

Works with normal and addressable prefabs.

To use custom types as a key, you'll need to create a new class that implements one of these abstract classes.

A version that uses string as a key is already implemented.

Why bother writing custom editor?

So you don't have to manually attach everytime you make a change. You can do it all with one click.

Addressable Auto Find

Normal Prefabs

Search in folder. Base class name: PrefabLoaderClassic

Addressable prefabs

Search assets with label. Base class name: PrefabLoaderAddressable

Public Methods

Instantiate

String Key Implementation

You can copy these steps if you want to create other custom types.

PrefabLoaderClassicString and PrefabLoaderAddressableString

Step 1: Create Your Class

// Normal Prefabs
public abstract class PrefabLoaderClassicString : PrefabLoaderClassic<string>
{
}
// Addressable Prefabs
public abstract class PrefabLoaderAddressableString : PrefabLoaderAddressable<string>
{

}

Step 2: Create Editor scripts

// Normal Prefabs
[CustomEditor(typeof(PrefabLoaderClassicString), true)]
public class PrefabLoaderClassicStringEditor : PrefabLoaderClassicEditor<string, GameObject>
{
    public override string GetKeyFromFileName(string name)
    {
        return name;
    }
}
// Addressable Prefabs
[CustomEditor(typeof(PrefabLoaderAddressableString), true)]
public class PrefabLoaderAddressableStringEditor : PrefabLoaderAddressableEditor<string, AssetReference>
{
    public override string GetKeyFromFileName(string name)
    {
        return name;
    }
}
