Use this class to implement specialized versions of the built-in transform tools. Built-in transform tools include Move, Rotate, Scale, Rect, and Transform.

GetAdditionalToolTypes | Get an additional collection of tools to display in the same category as the built-in transform tools. |
OnActivated | Invoked after this EditorToolContext becomes the active tool context. |
OnToolGUI | Implements any common functionality for the set of manipulation tools available for this context. |
OnWillBeDeactivated | Invoked before this EditorToolContext stops being the active tool context. |
PopulateMenu | Adds menu items to the Scene view context menu. |
ResolveTool | Returns the matching EditorTool type for the specified Tool given the context. |
GetEditorToolType | Defines the EditorTool type for a given Tool. |
hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
name | The name of the object. |
GetInstanceID | Gets the instance ID of the object. |
ToString | Returns the name of the object. |
Destroy | Removes a GameObject, component or asset. |
DestroyImmediate | Destroys the object obj immediately. You are strongly recommended to use Destroy instead. |
DontDestroyOnLoad | Do not destroy the target Object when loading a new Scene. |
FindAnyObjectByType | Retrieves any active loaded object of Type type. |
FindFirstObjectByType | Retrieves the first active loaded object of Type type. |
FindObjectsByType | Retrieves a list of all loaded objects of Type type. |
Instantiate | Clones the object original and returns the clone. |
CreateInstance | Creates an instance of a scriptable object. |
bool | Does the object exist? |
operator != | Compares if two objects refer to a different object. |
operator == | Compares two object references to see if they refer to the same object. |
Awake | This function is called when the ScriptableObject script is started. |
OnDestroy | This function is called when the scriptable object will be destroyed. |
OnDisable | This function is called when the scriptable object goes out of scope. |
OnEnable | This function is called when the object is loaded. |
OnValidate | Editor-only function that Unity calls when the script is loaded or a value changes in the Inspector. |
Reset | Reset to default values. |
