NGUI: Events(Event Functions)

NGUI의 이벤트 함수를 SendMessage로 호출하려고 함수 원형을 찾아보고 올려놓음.

UICamera sends out the following events to colliders:

• OnHover (isOver) is sent when the mouse hovers over a collider or moves away.
• OnPress (isDown) is sent when a mouse button gets pressed on the collider.
• OnSelect (selected) is sent when a mouse button is first pressed on a game object. Repeated presses on the same object won't result in a new OnSelect.
• OnClick () is sent with the same conditions as OnSelect, with the added check to see if the mouse has not moved much. UICamera.currentTouchID tells you which button was clicked.
• OnDoubleClick () is sent when the click happens twice within a fourth of a second. UICamera.currentTouchID tells you which button was clicked.
• OnDragStart () is sent to a game object under the touch just before the OnDrag() notifications begin.
• OnDrag (delta) is sent to an object that's being dragged.
• OnDragOver (draggedObject) is sent to a game object when another object is dragged over its area.
• OnDragOut (draggedObject) is sent to a game object when another object is dragged out of its area.
• OnDragEnd () is sent to a dragged object when the drag event finishes.
• OnInput (text) is sent when typing (after selecting a collider by clicking on it).
• OnTooltip (show) is sent when the mouse hovers over a collider for some time without moving.
• OnScroll (float delta) is sent out when the mouse scroll wheel is moved.
• OnKey (KeyCode key) is sent when keyboard or controller input is used.

To tap into them in your own custom scripts, simply create a script with the appropriate function, such as:

1. void OnPress (bool isPressed)
2. {
3.     if (isPressed) Debug.Log("I was pressed on!");
4.     else Debug.Log("I was unpressed");
5. }

Pro-Tip #2

You can subscribe to events from any script using delegates: UICamera.onClick, UICamera.onHover, etc. These delegates will be called just before the actual notification gets sent to the proper object. You can use this functionality to listen in for events on a script regardless of whether they would be going to that script's game object or not.
