How to Install

Library distributed as git package (How to install package from git URL)
Git URL: https://github.com/codewriter-packages/Tri-Inspector.git

Localization package dependency
Tri Inspector automatically installs Localization package as dependency.
If you are not using localization package and do not want to install it, you can install a stub package instead.
Git URL: https://github.com/codewriter-packages/Unity-Localization-Stub-for-Tri-Inspector.git

Roadmap

Each star ★ on the project page brings new features closer. You can suggest new features in the Discussions.

Samples

TriInspector has built-in samples at Tools/Tri Inspector/Samples menu.

Attributes

Misc

ShowInInspector

Shows non-serialized property in the inspector.

private float _field;

[ShowInInspector]
private bool _myToggle;

[ShowInInspector]
public float ReadOnlyProperty => _field;

[ShowInInspector]
public float EditableProperty
{
    get => _field;
    set => _field = value;
}

HideReferencePicker

Tri Inspector by default shows a polymorphic type picker for [SerializeReference] and [ShowInInspector]. It can be hidden with a [HideReferencePicker] attribute.

[SerializeReference]
public MyReferenceClass clazz1 = new MyReferenceClass();

[SerializeReference, HideReferencePicker]
public MyReferenceClass clazz2 = new MyReferenceClass();

[ShowInInspector, HideReferencePicker]
public MyReferenceClass Clazz3 { get; set; } = new MyReferenceClass();

[Serializable]
public class MyReferenceClass
{
    public int inner;
}

PropertyOrder

Changes property order in the inspector.

public float first;

[PropertyOrder(0)]
public float second;

ReadOnly

Makes property non-editable in the inspector.

[ReadOnly]
public Vector3 vec;

OnValueChanged

Invokes callback on property modification.

[OnValueChanged(nameof(OnMaterialChanged))]
public Material mat; 

private void OnMaterialChanged()
{
    Debug.Log("Material changed!");
}

HideMonoScript

Hides the default Script property in the inspector.

[HideMonoScript]
public class NewBehaviour : MonoBehaviour
{
}

Validation

Tri Inspector has some builtin validators such as missing reference and type mismatch error. Additionally you can mark out your code with validation attributes or even write own validators.

[ValidateInput(nameof(ValidateTexture))]
public Texture tex;

    return TriValidationResult.Valid;
}

Groups

Properties can be grouped in the inspector using the Group attribute.

[Group("one")] public float a;
[Group("one")] public float b;

[Group("two")] public float c;
[Group("two")] public float d;

public float e;

If you have a lot of properties and group attributes take up too much space, then you can combine multiple properties at once using the GroupNext attribute.

[GroupNext("one")]
public float a;
public float b;

[GroupNext("two")]
public float c;
public float d;

[UnGroupNext]
public float e;

Box Group

[DeclareBoxGroup("box", Title = "My Box")]
public class BoxGroupSample : ScriptableObject
{
    [Group("box")] public int a;
    [Group("box")] public bool b;
}

Foldout Group

[DeclareFoldoutGroup("foldout", Title = "$" + nameof(DynamicTitle))]
public class FoldoutGroupSample : ScriptableObject
{
    [Group("foldout")] public int a;
    [Group("foldout")] public bool b;
    
    public string DynamicTitle => "My Foldout";
}

Toggle Group

[DeclareToggleGroup("toggle", Title = "$" + nameof(DynamicTitle))]
public class ToggleGroupSample : ScriptableObject
{
    [Group("toggle")] public bool enabled;
    [Group("toggle")] public int a;
    [Group("toggle")] public bool b;
    
    public string DynamicTitle => "My Toggle";
}

    [Group("tabs"), Tab("Two")] public float b;
    [Group("tabs"), Tab("Three")] public bool c;
}

Horizontal Group

[DeclareHorizontalGroup("vars")]

    [Group("vars")] public int b;
    [Group("vars")] public int c;
}

Vertical Group

    [Group("horizontal/vars")] public float b;

    [Button, Group("horizontal/buttons")]
    public void ButtonA() { }

    [Button, Group("horizontal/buttons")]
    public void ButtonB() { }
}

Integrations

Odin Inspector

Tri Inspector is able to work in compatibility mode with Odin Inspector. In this mode, the primary interface will be drawn by the Odin Inspector. However, parts of the interface can be rendered by the Tri Inspector.

In order for the interface to be rendered by Tri instead of Odin, it is necessary to mark classes with [DrawWithTriInspector] attribute.

Alternatively, you can mark the entire assembly with an attribute [assembly:DrawWithTriInspector] to draw all types in the assembly using the Tri Inspector.

Odin Validator

Tri Inspector is integrated with the Odin Validator so all validation results from Tri attributes will be shown in the Odin Validator window.
