distribution
Syntax
member(whichCastmember).modelResource(whichModelResource).\
emitter.distribution
Description
3D emitter property; indicates how the particles of a particle system are distributed across the
emitter’s region at their creation. The possible values of this property are #gaussian or #linear.
The default value is
#linear.
Example
In this example, ThermoSystem is a model resource whose type is #particle. This statement sets
the
distribution property of ThermoSystem’s emitter to #linear, which causes the particles of
ThermoSystem to be evenly distributed across their origin region at their birth.
member("Fires").modelResource("ThermoSystem").emitter.\
distribution = #linear

dither
Syntax
member(whichMember).dither
the dither of member whichMember
Description
Bitmap cast member property; dithers the cast member when it is displayed at a color depth of 8
bits or less (256 colors) if the display must show a color gradation not in the cast member (TRUE),
or tells Director to choose the nearest color out of those available in the current palette (
FALSE).
For both performance and quality reasons, you should set dither to TRUE only when higher
display quality is necessary. Dithering is slower than remapping, and artifacts may be more
apparent when animating over a dithered image.
If the color depth is greater than 8 bits, this property has no effect.

do
Syntax
do stringExpression
Description
Command; evaluates stringExpression and executes the result as a Lingo statement. This
command is useful for evaluating expressions that the user has typed and for executing commands
stored in string variables, fields, arrays, and files.
Using uninitialized local variables within a
do command creates a compile error. Initialize any
local variables in advance.
Note: This command does not allow global variables to be declared; these variables must be declared in advance.
