* The function ::IsHitByClick() determines what is clickable by this Tool. The default is
|
|
* to return true, which means the click will activate anywhere (the Tool itself has no
|
|
* notion of Actors, Components, etc). You can override this function to, for example,
|
|
* filter out clicks that don't hit a target object, etc.
|
|
*
|
|
* The function ::OnClicked() implements the action that will occur when a click happens.
|
|
* You must override this to implement any kind of useful behavior.
