880 Chapter 14: Properties

Description

Mouse property; indicates the vertical position of the mouse cursor, in pixels, from the top of the

Stage. Read-only.

The value of this property increases as the cursor moves down and decreases as the cursor

moves up.

The

mouseV property is useful for moving sprites to the vertical position of the mouse cursor and

checking whether the cursor is within a region of the Stage. Using the

mouseH and mouseV

properties together, you can identify the cursor’s exact location.

Example

This handler moves sprite 1 to the mouse pointer location and updates the Stage when the user

clicks the mouse button:

-- Lingo syntax

on mouseDown

sprite(1).locH = _mouse.mouseH

sprite(1).locV = _mouse.mouseV

end

// JavaScript syntax

function mouseDown() {

sprite(1).locH = _mouse.mouseH;

sprite(1).locV = _mouse.mouseV;

}

This statement tests whether the pointer is more than 10 pixels above or below a starting point

and, if it is, sets the variable

vFar to TRUE:

-- Lingo syntax

startV = 7

if (abs(_mouse.mouseV - startV) > 10) then

vFar = TRUE

end if

// JavaScript syntax

var startV = 7

if (Math.abs(_mouse.mouseV - startV) > 10) {

var vFar = true;

}
