• Property attributes for Unity fields
• Unity minimum version: 2020.3
• Current version: 3.0.0
• Licence: MIT

Just use one of the following attributes:

• AssetsOnly: only select assets references.
• Required: use it on strings, exposed and object reference types. If the value is null or empty, an error message will be displayed on Inspector bellow the given attribute.
• Tag: use it only with string fields. It'll replace the string field by a tag popup.
• DisableInPlayMode: use this to prevent users from editing a property when in play mode.

using UnityEngine;
using ActionCode.Attributes;

public sealed class TestBehaviour : MonoBehaviour
{
    [AssetsOnly(typeof(GameObject))] public GameObject player;
    [Required] public string playerId;
    [Tag] public string playerTag = "Player";
}

• ShowIf: use it to show properties based on the current state of the object.

using ActionCode.Attributes;

public sealed class TestBehaviour : MonoBehaviour
{
    [Range(0, 20)] public int powerLevel;
    [ShowIf("powerLevel", LogicalOperatorType.GreaterOrEqual, 10)]
    public string powerLevelName = "Super Power";
}

• ReadonlyIf: use it to disallow changes in properties based on the current state of the object.

using ActionCode.Attributes;

public sealed class TestBehaviour : MonoBehaviour
{
    public RigidbodyConstraints2D constraint;
    [ReadonlyIf("constraint", RigidbodyConstraints2D.FreezePositionX)]
    public float forceX = 10F;
}

• CreateButton: use it to add a Create Button next to a ScriptableObject field if no reference is set.

using ActionCode.Attributes;

public sealed class TestBehaviour : MonoBehaviour
{
    [CreateButton(typeof(SceneTransition))]
    public SceneTransition defaultTransition;
}
