registerScript
(
eventName
,
handlerName
,
scriptInstance
)
Registers a handler named
handlerName
that is called in the
instance
scriptInstance
when the event
eventName
occurs.
If
scriptInstance
is 0, a movie script handler called
eventName
is called.
The user defines what
eventName
is.
TRUE (1)
or
FALSE (0)
,
with
TRUE (1)
indicating that the
event happened
and
FALSE (0)
that it did not
translate
(
xIncrement
,
yIncrement
,
zIncrement
,
relativeTo
)
Moves the light forward by
xIncrement
along the x-axis,
yIncrement
along the y-axis, and
zIncrement
along the z-axis.
The
relativeTo
parameter is optional. It determines how
arguments are interpreted. The possible values are as follows:
#self
: the default. Increments are applied relative to the light’s local
coordinate system.
#parent
: increments are relative to the light’s parent’s coordinate
system.
#world
: increments are relative to the world’s coordinate system.
Equivalent to
#parent
if the parent is the world.
node
(model, light, camera, or group): increments are relative to the
argument’s coordinate system.
Nothing
translate
(
direction
Vector
,
relativeTo
)
Moves the light
directionVector.length()
in the direction
of the vector
directionVector
. The
relativeTo
argument is
optional and defaults to
#self
.
Nothing
translate(x,y,z,
relativeTo)
Moves the light distance
x
along the x-axis, distance
y
along the y-
axis, and distance
z
along the z-axis. The
relativeTo
argument is
optional and defaults to
#self
.
This command can also be written as
translate
(vector(
x
,
y
,
z
)
relativeTo
)
Nothing
rotate(x,y,z,
relativeTo)
Rotates the light by
x
degrees around the x-axis, y degrees around
the y-axis, and z degrees around the z-axis.
The
relativeTo
argument is optional and defaults to
#self
. If
included, it defines the coordinate space of the axes.
This command can also be written as
rotate
(vector(
x
,
y
,
z
)
relativeTo
)
Nothing
rotate (position,
axis, angle,
relativeTo)
Rotates the light around the axis vector in the specified position the
specified number of degrees. The
relativeTo
argument is
optional and defaults to
#self
.
Nothing
pointAt(world
Position,
worldUp)
Rotates the light until it points at the world-relative position
worldPosition
. The optional
worldUp
argument indicates the
position of the light’s Up axis.
Both the object-relative axes are defined by the
pointAtOrientation
property. Default values are an object-
relative forward direction of vector
(0,0,-1)
and an object-
relative up direction of vector
(0,1,0)
.
Nothing
getWorld
Transform()
Calculates and returns a transform that converts object-relative
positions for this light into world-relative positions.
