Support for AudioClips that can be played when double-clicking on an asset

[fydar]

When a ScriptableObject asset that has either:

• An [AssetIcon] attribute is on a member that returns an AudioClip.
• An [AssetIcon] attribute is on a method that accepts an IAssetPreview as a parameter.

And when:

• The user double-clicks the ScriptableObject asset.
• The user right-clicks the ScriptableObject asset and selects 'Open'.
• The user selects the ScriptableObject asset and presses return.

The action associated with the ScriptableObject is invoked.

Playing an AudioClip should also be configurable. Every play of the AudioClip should allow the user to vary the following:

• The volume of the AudioClip.
• The pitch of the AudioClip.
• How long the AudioClip should be played.

Examples

An AudioClip should be quickly and easily associated with the ScriptableObject.

using AssetIcons;
using UnityEngine;

[CreateAssetMenu]
public class ItemInformation : ScriptableObject
{
    [AssetIcon]
    public AudioClip PickupSound;
}

An IAssetPreview should be used to allow the user to have more control over how the ScriptableObject icon is previewed.

using AssetIcons;
using UnityEngine;

[CreateAssetMenu]
public class ItemInformation : ScriptableObject
{
    public AudioClip PickupSound;

    [AssetIcon]
    public void OnPreviewAsset(IAssetPreview assetPreview)
    {
        assetPreview.PlaySound(PickupSound, 0.5f, 0.95f);
    }
}
