# Reference
### EditorActionButtonAttribute
an attribute class that is used for defining custom editor action buttons on static methods to draw them in component or object headers.
| type | parameter | description |
| ------ | ---------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| string | id | unique per type. There can be multiple id with same value on different targetTypes |
| Type | targetType | Show buttons on the target type and its derived types. If a type that derives from the target type is added separately with the same ID, the button will not be shown on that type and its derived types. |
| string | iconPath | path to an texture under the Assets/Editor Default Resources folder
e.g. "Assets/Editor Default Resource/SubFolder/example.png" only the bold part should be used.
|
| string | tooltip | small message to show on hover |
| int | priority | button placement order |
**Use Case:**
```csharp
//Method can have both single parameter or array parameter.
//Array sends all selected contexts and single sends only the first from selected.
[EditorActionButton("print", typeof(Transform), "SubFolder/example.png",
"Print transform position", 0)]
private static void PrintTransform(Object context)
{
Debug.Log(((Transform)context).position);
}
//---------------or---------------
[EditorActionButton("print", typeof(Transform), "SubFolder/example.png",
"Print transform position", 0)]
private static void PrintTransform(Object[] contexts)
{
foreach(var context in contexts)
{
Debug.Log(((Transform)context).position);
}
}
```
### EditorActionButtonValidateAttribute
Helper attribute for show/hide/disable condition management of the button
| type | parameter | description |
| ------ | ---------- | ------------------------------------------------------------- |
| Type | targetType | Determines which type's buttons should be under validation |
| string | id | used to find editor action button with this id for validation |
| return type | description |
| ----------- | ------------------------------------------------- |
| ButtonState | tells what to do with the button after validation |
**Use Case:**
```csharp
//Method can have both single parameter or array parameter.
//Array sends all selected contexts and single sends only the first from selected
[EditorActionButtonValidate(typeof(Transform),"print")]
private static ButtonState PrintTransform(Object context)
{
//Will hide button on rect transforms
return (context is RectTransform) ?
ButtonState.Hidden : ButtonState.Active;
}
//---------------or---------------
[EditorActionButtonValidate(typeof(Transform),"print")]
private static ButtonState PrintTransform(Object[] contexts)
{
//Will hide button on rect transforms
return (contexts.Any(ctx => ctx is RectTransform)) ?
ButtonState.Hidden : ButtonState.Active;
}
```
### GameObjectActionButtonAttribute
an attribute class that is used for defining custom editor action buttons on static methods to draw them in inspector header or hierarchy item
| type | parameter | description |
| --------------- | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| string | id | unique per placementType. There can be multiple id with same value on different placementType |
| GOPlacementType | placementType | Determines which area the buttons should draw on |
| string | iconPath | path to an texture under the Assets/Editor Default Resources folder
e.g. "Assets/Editor Default Resource/SubFolder/example.png" only the bold part should be used.
|
| string | tooltip | small message to show on hover |
| int | priority | button placement order |
**Use Case:**
```csharp
//Method can have both single parameter or array parameter.
//Array sends all selected contexts and single sends only the first from selected
[EditorActionButton("print", GOPlacementType.Header, "SubFolder/example.png",
"Print transform position", 0)]
private static void PrintComponentCount(GameObject context)
{
var components = context.GetComponent();
Debug.Log(components.Length);
}
//---------------or---------------
[EditorActionButton("print", GOPlacementType.Hierarchy, "SubFolder/example.png",
"Print transform position", 0)]
private static void PrintComponentCount(GameObject[] contexts)
{
foreach(GameObject context in contexts)
{
var components = context.GetComponent();
Debug.Log(components.Length);
}
}
```
### GameObjectActionButtonValidateAttribute
Helper attribute for show/hide/disable condition management of the button
| type | parameter | description |
| --------------- | ------------- | ------------------------------------------------------------------ |
| string | id | used to find game object action button with this id for validation |
| GOPlacementType | placementType | Determines which area the buttons should be validated on |
**Use Case:**
```csharp
//Method can have both single parameter or array parameter.
//Array sends all selected contexts and single sends only the first from selected
[GameObjectActionValidate("print", GOPlacementType.Header)]
private static ButtonState PrintComponentCount(GameObject context)
{
//Disable if target go is not a file asset
return EditorUtility.IsPersistent(context) ?
ButtonState.Disabled : ButtonState.Active;
}
//---------------or---------------
[GameObjectActionValidate("print", GOPlacementType.Header)]
private static void PrintComponentCount(GameObject[] contexts)
{
//Disable if target go is not a file asset
return context.All(ctx => EditorUtility.IsPersistent(ctx)) ?
ButtonState.Disabled : ButtonState.Active;
}
```
