What is the correct Resource.Load path?

Question

I'm trying to load a Texture2D (.png) resource using Resource.Load. I've tried following path patterns:

Assets/CaseSensitivePath/TextureName
CaseSensitivePath/TextureName
Assets/CaseSensitivePath/TextureName.png
CaseSensitivePath/TextureName.png

Every time, Resource.Load(path, typeof(Texture2D)) returns null. This is my code and error handling:

public class LazyResource<T> where T : UnityEngine.Object
{

    //Path is read-only
    public string path { get { return _path; } }
    private string _path = "";
    //Whether NOT FOUND warning was thrown
    //in that case, further load attemts are ommited and the resource returns always null...
    public bool failed = false;
    //Constructor uses the path as first parameter
    public LazyResource(string path) {
        _path = path;
    }
    //Cached resource
    private T cache = null;

    public T res
    {
        get
        {
            //Does not re-try if it failed before
            if (cache == null && !failed)
            {
                //Load the proper type of resource
                cache = (T)Resources.Load(_path, typeof(T));
                //Throw warning (once)
                if (cache == null)
                {
                    Debug.LogWarning("Icon not found at '" + _path + "'!");
                    failed = true;
                }
            }
            //Can return null
            return cache;
        }
    }
}

Error:

Icon not found at 'Textures/GUI/Build/egg'!

What is the correct path to load a texture in the Unity3D project?

Answer 1

You don't necessarily need a path. You can simply type

Resources.Load<Texture2D>("MyTexture");

If TextureName is in a folder then you type:

Resources.Load<Texture2D>("MyFolder/MyTexture");

If you want to use Resources.Load then you need to put the resource in the Resource folder. This is how it looks in the Editor.
