自定义事件（MonoBehaviour），让它处理更多的事件

void OnHover (bool isOver) ? Sent out when the mouse hovers over the collider or moves away from it.Not sent on touch-based devices.
void OnPress (bool isDown) ? Sent when a mouse button (or touch event) gets pressed over the collider (with ‘true’) and when it gets released (with ‘false’, sent to the same collider even if it’s released elsewhere).
void OnClick() ? Sent to a mouse button or touch event gets released on the same collider as OnPress.UICamera.currentTouchID tells you which button was clicked.
void OnDoubleClick () ? Sent when the click happens twice within a fourth of a second.UICamera.currentTouchID tells you which button was clicked.
void OnSelect (bool selected) ? Same as OnClick, but once a collider is selected it will not receive any further OnSelect events until you select some other collider.
void OnDrag (Vector2 delta) ? Sent when the mouse or touch is moving in between of OnPress(true) and OnPress(false).
void OnDrop (GameObject drag) ? Sent out to the collider under the mouse or touch when OnPress(false) is called over a different collider than triggered the OnPress(true) event. The passed parameter is the game object of the collider that received the OnPress(true)
event.
void OnInput (string text) ? Sent to the same collider that received OnSelect(true) message after typing something. You likely won’t need this, but it’s used by UIInput
void OnTooltip (bool show) ? Sent after the mouse hovers over a collider without moving for longer thantooltipDelay, and when the tooltip should be hidden. Not sent on touch-based devices.
void OnScroll (float delta) is sent out when the mouse scroll wheel is moved.
void OnKey (KeyCode key) is sent when keyboard or controller input is used.详细目录
