floatPrecision
Usage
the floatPrecision
Description
Movie property; rounds off the display of floating-point numbers to the number of decimal places
specified. The value of
floatPrecision must be an integer. The maximum value is 15
significant digits; the default value is 4.
The
floatPrecision property determines only the number of digits used to display
floating-point numbers; it does not change the number of digits used to perform calculations.
• If floatPrecision is a number from 1 to 15, floating-point numbers display that number of
digits after the decimal point. Trailing zeros remain.
• If floatPrecision is zero, floating-point numbers are rounded to the nearest integer. No
decimal points appear.
• If floatPrecision is a negative number, floating-point numbers are rounded to the absolute
value for the number of decimal places. Trailing zeros are dropped.
This property can be tested and set.
Example
This statement rounds off the square root of 3.0 to three decimal places:
the floatPrecision = 3
x = sqrt(3.0)
put x
-- 1.732
This statement rounds off the square root of 3.0 to eight decimal places:
the floatPrecision = 8
put x
-- 1.73205081

Usage
member(whichCastmember).camera(whichCamera).fog.color
sprite(whichSprite).camera{(index)}.fog.color
member(whichCastmember).camera(whichCamera).fog.decayMode
sprite(whichSprite).camera{(index)}.fog.decayMode
member(whichCastmember).camera(whichCamera).fog.enabled
sprite(whichSprite).camera{(index)}.fog.enabled
member(whichCastmember).camera(whichCamera).fog.far
sprite(whichSprite).camera{(index)}.fog.far
member(whichCastmember).camera(whichCamera).fog.near
sprite(whichSprite).camera{(index)}.fog.near
Description
3D camera property; fog introduces a coloring and blurring of models that increases with distance
from the camera. The effect is similar to real fog, except that it can be any color.
