point()

Usage

-- Lingo syntax
point(intH, intV)

// JavaScript syntax
point(intH, intV);

Description

Top level function and data type. Returns a point that has specified horizontal and vertical coordinates.

A point has both a locH and a locV property.

Point coordinates can be changed by arithmetic operations using Lingo only. For example, the following two points can be added together using Lingo, but NaN is returned using JavaScript syntax:

-- Lingo
pointA = point(10,10)
pointB = point(5,5)
put(pointA + pointB)
-- point(15,15)

// JavaScript syntax
var pointA = point(10,10);
var pointB = point(5,5);
trace(pointA + pointB);
// NaN

To see an example of point() used in a completed movie, see the Imaging and Vector Shapes movies in the Learning/Lingo folder inside the Director application folder.

Parameters

intH Required. An integer that specifies the horizontal coordinate of the point.

intV Required. An integer that specifies the vertical coordinate of the point.

Example

This statement sets the variable lastLocation to the point (250, 400):

-- Lingo syntax
lastLocation = point(250, 400)

// JavaScript syntax
var lastLocation = point(250, 400);

This statement adds 5 pixels to the horizontal coordinate of the point assigned to the variable myPoint:

-- Lingo syntax
myPoint.locH = myPoint.locH + 5

// JavaScript syntax
myPoint.locH = myPoint.locH + 5;

In Lingo only, the following statements set a sprite's Stage coordinates to mouseH and mouseV plus 10 pixels. The two statements are equivalent.

-- Lingo syntax
sprite(_mouse.clickOn).loc = point(_mouse.mouseH, _mouse.mouseV) \
+ point(10, 10)
sprite(_mouse.clickOn).loc = _mouse.mouseLoc + 10
