## Roadmap ![GitHub Repo stars](https://img.shields.io/github/stars/codewriter-packages/Tri-Inspector?style=social)
Each star ★ on the project page brings new features closer. See roadmap and more info [here](https://github.com/codewriter-packages/Tri-Inspector/issues/9).

## Samples

TriInspector has built-in samples at `Tools/Tri Inspector/Samples` menu.
![Samples](https://user-images.githubusercontent.com/26966368/177045336-a3fcf438-3e70-45d0-b753-299e577b2010.png)

## Attributes

### Misc

#### ShowInInspector

Shows non-serialized property in the inspector.

![ShowInInspector](https://user-images.githubusercontent.com/26966368/168230693-a1a389a6-1a3b-4b94-b4b5-0764e88591f4.png)

```csharp
private float _field;

[ShowInInspector]
public float ReadOnlyProperty => _field;

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

#### PropertyOrder

Changes property order in the inspector.

![PropertyOrder](https://user-images.githubusercontent.com/26966368/168231223-c6628a8d-0d0a-47c1-8850-dc4e789fa14f.png)

```csharp
public float first;

[PropertyOrder(0)]
public float second;
```

#### ReadOnly

Makes property non-editable in the inspector.

![ReadOnly](https://user-images.githubusercontent.com/26966368/168231817-948ef153-eb98-42fb-88ad-3e8d17925b43.png)

```csharp

public Vector3 vec;
```

#### OnValueChanged

Invokes callback on property modification.

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

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

### 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.

## 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.

![Odin-Validator-Integration](https://user-images.githubusercontent.com/26966368/169645537-d8f0b50f-46af-4804-95e8-337ff3b5ae83.png)
