Parameters
Required. An integer that specifies the sprite whose horizontal coordinates are
intSpriteNum
evaluated against
Required. An integer to be evaluated against by the horizontal coordinates of the left and
intPosn
right sides of the sprite identified by
Example
These statements check the
coordinates of 40 and 60:
-- Lingo syntax
put(constrainH(1, 20)) -- 40
put(constrainH(1, 55)) -- 55
put(constrainH(1, 100)) -- 60
// JavaScript syntax
put(constrainH(1, 20)); // 40
put(constrainH(1, 55)); // 55
put(constrainH(1, 100)); // 60
This statement constrains a moveable slider (sprite 1) to the edges of a gauge (sprite 2) when the
mouse pointer goes past the edge of the gauge:
-- Lingo syntax
sprite(1).locH = _movie.constrainH(2, _mouse.mouseH)
// JavaScript syntax
sprite(1).locH = _movie.constrainH(2, _mouse.mouseH);

Usage
-- Lingo syntax
_movie.constrainV(intSpriteNum, intPosn)
// JavaScript syntax
_movie.constrainV(intSpriteNum, intPosn);
Description
Movie method; returns an integer whose value depends on the vertical coordinates of the top and
bottom sides of a sprite.
The returned integer can be one of three possible values.
•
If the
intPosn
returned integer equals
•
If the
intPosn
integer changes to the value of the sprite's top coordinate.
•
If the
intPosn
returned integer changes to the value of the sprite's bottom coordinate.
This method does not change the sprite's properties.
