perpendicularTo
Usage
vector1.perpendicularTo(vector2)
Description
3D vector command; returns a vector perpendicular to both the original vector and a second
vector. This command is equivalent to the vector
crossProduct command.
Parameters
vector2
Required. Specifies the second vector.
Example
In this example, pos1 is a vector on the x axis and pos2 is a vector on the y axis. The value
returned by
pos1.perpendicularTo(pos2) is vector( 0.0000, 0.0000, 1.00000e4 ). The
last two lines of the example show the vector which is perpendicular to both pos1 and pos2.
pos1 = vector(100, 0, 0)
pos2 = vector(0, 100, 0)
put pos1.perpendicularTo(pos2)
-- vector( 0.0000, 0.0000, 1.00000e4 )

pictureP()
Usage
-- Lingo syntax
pictureP(pictureValue)
// JavaScript syntax
pictureP(pictureValue);
Description
Function; reports whether the state of the picture member property for the specified cast
member is
TRUE (1) or FALSE (0).
Because
pictureP doesn’t directly check whether a picture is associated with a cast member, you
must test for a picture by checking the cast member’s
picture member property.
Parameters
pictureValue Required. Specifies a reference to the picture of a cast member.
