UnityAsyncPrefabLoading

A complete one-file async prefab loading and caching solution for Unity

What does it do?

• Load any amount of Prefabs at a time from Resources in a non blocking call
• Optional resource caching that avoids double resource loading
• Simple callbacks for individual prefabs loaded and for groups of prefab loaded
• Optional and automatic async GO instantition
• Calculates simple progress and a timer for all prefab loading operations

Why?

• Avoid Prefab loading lag by having both loading and instantiation in an asyncronous call
• Execute code when groups of prefabs have finished asyncronously with optional C# actions
• Cache prefabs by keeping inactive parent objects in the scene and by avoiding Resources.Load

Usage

• Load prefabs asyncronously with a single callback that is invoked when all the prefabs are loaded.

// strings in the first parameter must match files in 'Resources'
GroupLoader.Instance.LoadResources(new List<string>{"prefab1", "level/prefab", "prefab2"}, 
  () => {
    Debug.Log("All prefabs loaded!");
  });

• Load prefabs asyncronously with a callback for each prefab and a single callback that is invoked when all the prefabs are loaded.

// strings in the first parameter must match files in 'Resources'
GroupLoader.Instance.LoadResources(new List<Resource>{
  new Resource{
    Name = "level/prefab",
    FinishCallback = () => {
      Debug.Log("Resource loaded: " + this.Name);
    }
  },
  new Resource{
    Name = "prefab1",
    FinishCallback = () => {
      Debug.Log("Resource loaded: " + this.Name);
    }
  }
}, 
  () => {
    Debug.Log("All prefabs loaded!");
  });

• Load prefabs asyncronously, caching some prefabs, with a callback for each prefab and a single callback that is invoked when all the prefabs are loaded.

// strings in the first parameter must match files in 'Resources'
GroupLoader.Instance.LoadResources(new List<Resource>{
  new Resource{
    Name = "level/prefab",
    CacheResult = true,
    FinishCallback = () => {
      Debug.Log("Resource loaded: " + this.Name);
    }
  },
  new Resource{
    Name = "prefab1",
    FinishCallback = () => {
      Debug.Log("Resource loaded: " + this.Name);
    }
  }
}, 
  () => {
    Debug.Log("All prefabs loaded!");
  });
