Git URL: https://github.com/codewriter-packages/Tri-Inspector.git

After package installation run the Installer by double clicking on it.

Roadmap

Each star ★ on the project page brings new features closer. See roadmap and more info here.

Attributes

Misc

ShowInInspector

Shows non-serialized property in the inspector.

private float _field;

[ShowInInspector]
public float ReadOnlyProperty => _field;

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

Customization

Custom Drawers

Custom Value Drawer

using TriInspector;
using UnityEditor;
using UnityEngine;

[assembly: RegisterTriValueDrawer(typeof(BoolDrawer), TriDrawerOrder.Fallback)]

public class BoolDrawer : TriValueDrawer<bool>
{
    public override float GetHeight(float width, TriValue<bool> propertyValue, TriElement next)
    {
        return EditorGUIUtility.singleLineHeight;
    }

    public override void OnGUI(Rect position, TriValue<bool> propertyValue, TriElement next)
    {
        var value = propertyValue.Value;

        EditorGUI.BeginChangeCheck();

        value = EditorGUI.Toggle(position, propertyValue.Property.DisplayNameContent, value);

        if (EditorGUI.EndChangeCheck())
        {
            propertyValue.Value = value;
        }
    }
}

Custom Attribute Drawer

using TriInspector;
using UnityEditor;
using UnityEngine;

[assembly: RegisterTriAttributeDrawer(typeof(LabelWidthDrawer), TriDrawerOrder.Decorator)]

public class LabelWidthDrawer : TriAttributeDrawer<LabelWidthAttribute>
{
    public override void OnGUI(Rect position, TriProperty property, TriElement next)
    {
        var oldLabelWidth = EditorGUIUtility.labelWidth;

        EditorGUIUtility.labelWidth = Attribute.Width;
        next.OnGUI(position);
        EditorGUIUtility.labelWidth = oldLabelWidth;
    }
}

Custom Group Drawer

using TriInspector;
using TriInspector.Elements;

[assembly: RegisterTriGroupDrawer(typeof(TriBoxGroupDrawer))]

public class TriBoxGroupDrawer : TriGroupDrawer<DeclareBoxGroupAttribute>
{
    public override TriPropertyCollectionBaseElement CreateElement(DeclareBoxGroupAttribute attribute)
    {
        // ...
    }
}

Validators

Custom Value Validator

using TriInspector;

[assembly: RegisterTriValueValidator(typeof(MissingReferenceValidator<>))]

public class MissingReferenceValidator<T> : TriValueValidator<T>
    where T : UnityEngine.Object
{
    public override TriValidationResult Validate(TriValue<T> propertyValue)
    {
        // ...
    }
}

Custom Attribute Validators

using TriInspector;

[assembly: RegisterTriAttributeValidator(typeof(RequiredValidator), ApplyOnArrayElement = true)]

public class RequiredValidator : TriAttributeValidator<RequiredAttribute>
{
    public override TriValidationResult Validate(TriProperty property)
    {
        // ...
    }
}

Property Processors

Custom Property Hide Processor

using TriInspector;
using UnityEngine;

[assembly: RegisterTriPropertyHideProcessor(typeof(HideInPlayModeProcessor))]

public class HideInPlayModeProcessor : TriPropertyHideProcessor<HideInPlayModeAttribute>
{
    public override bool IsHidden(TriProperty property)
    {
        return Application.isPlaying;
    }
}

Custom Property Disable Processor

using TriInspector;
using UnityEngine;

[assembly: RegisterTriPropertyDisableProcessor(typeof(DisableInPlayModeProcessor))]

public class DisableInPlayModeProcessor : TriPropertyDisableProcessor<DisableInPlayModeAttribute>
{
    public override bool IsDisabled(TriProperty property)
    {
        return Application.isPlaying;
    }
}

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.
