## How to Install
Library distributed as git package ([How to install package from git URL](https://docs.unity3d.com/Manual/upm-ui-giturl.html))
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](https://github.com/codewriter-packages/Tri-Inspector/issues/9).
## Attributes
### Misc
#### ShowInInspector
Shows non-serialized property in the inspector.
```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.
```csharp
public float first;
[PropertyOrder(0)]
public float second;
```
#### ReadOnly
Makes property non-editable in the inspector.
```csharp
[ReadOnly]
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.
#### Required
```csharp
[Required]
public Material mat;
```
#### ValidateInput
```csharp
[ValidateInput(nameof(ValidateTexture))]
public Texture tex;
private TriValidationResult ValidateTexture()
{
if (tex == null) return TriValidationResult.Error("Tex is null");
if (!tex.isReadable) return TriValidationResult.Warning("Tex must be readable");
return TriValidationResult.Valid;
}
```

```csharp
[Title("InfoBox Message Types")]

public class BoolDrawer : TriValueDrawer
{
public override float GetHeight(float width, TriValue propertyValue, TriElement next)
{
return EditorGUIUtility.singleLineHeight;
}
public override void OnGUI(Rect position, TriValue propertyValue, TriElement next)
{
var value = propertyValue.Value;
EditorGUI.BeginChangeCheck();
value = EditorGUI.Toggle(position, propertyValue.Property.DisplayNameContent, value);

{
propertyValue.Value = value;
}
}
}
```

public class TriBoxGroupDrawer : TriGroupDrawer
{
public override TriPropertyCollectionBaseElement CreateElement(DeclareBoxGroupAttribute attribute)
{
// ...
}
}
```
#### Validators
Custom Value Validator
```csharp
using TriInspector;
[assembly: RegisterTriValueValidator(typeof(MissingReferenceValidator<>))]
public class MissingReferenceValidator : TriValueValidator
where T : UnityEngine.Object
{
public override TriValidationResult Validate(TriValue propertyValue)
{
// ...

{
public override TriValidationResult Validate(TriProperty property)
{
// ...
}
}
```
#### Property Processors
Custom Property Hide Processor
```csharp
using TriInspector;
using UnityEngine;
[assembly: RegisterTriPropertyHideProcessor(typeof(HideInPlayModeProcessor))]
public class HideInPlayModeProcessor : TriPropertyHideProcessor
{
public override bool IsHidden(TriProperty property)
{
return Application.isPlaying;
}
}
```
Custom Property Disable Processor
```csharp
using TriInspector;
using UnityEngine;
[assembly: RegisterTriPropertyDisableProcessor(typeof(DisableInPlayModeProcessor))]
public class DisableInPlayModeProcessor : TriPropertyDisableProcessor
{
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.
