Buttons are used on functions, and allows for clickable buttons in the inspector.

Inheritance
Example

The following example shows a component that has an initialize method, that can be called from the inspector.

public class MyComponent : MonoBehaviour
{
	[Button]
	private void Init()
	{
		// ...
	}
}
Example

The following example show how a Button could be used to test a function.

public class MyBot : MonoBehaviour
{
	[Button]
	private void Jump()
	{
		// ...
	}
}
Example

The following example show how a Button can named differently than the function it's been attached to.

public class MyComponent : MonoBehaviour
{
	[Button("Function")]
	private void MyFunction()
	{
		// ...
	}
}

Fields

DirtyOnClick
Whether the containing object or scene (if there is one) should be marked dirty when the button is clicked. True by default. Note that if this is false, undo for any changes caused by the button click is also disabled, as registering undo events also causes dirtying. 
public bool DirtyOnClick
DisplayParameters

Whether to display the button method's parameters (if any) as values in the inspector. True by default.

If this is set to false, the button method will instead be invoked through an ActionResolver or ValueResolver (based on whether it returns a value), giving access to contextual named parameter values like "InspectorProperty property" that can be passed to the button method.

public bool DisplayParameters
Expanded
If the button contains parameters, you can disable the foldout it creates by setting this to true. 
public bool Expanded
Icon
The icon to be displayed inside the button. 
public SdfIconType Icon
Name
Use this to override the label on the button. 
public string Name
Style
The style in which to draw the button. 
public ButtonStyle Style

Gets the height of the button. If it's zero or below then use default.
