Corrected the LScript software to detect ScreamerNet and behave properly
therein.
|
|
|
The LWIO Object Agent, provided to load() and save() UDFs, was missing a
writeVector() method for working with binary files. This has been
corrected.
|
|
|
A new surface command has been added to LScript for Modeler.
Copysurface() behaves like createsurface() in that it will create a new
surface designator, but copysurface() takes an additional (required)
parameter that is the name of an existing surface from whom settings will
be taken.
copysurface("ExistingSurface","NewSurface");

|
The conversion functions integer(), number() and vector() have been
altered so that they will scan a provided character string until they
find the first numeric occurrence (a number or a period [.] followed by a
number) before they attempt to convert.
x = integer("My number: 55"); // returns 55
x = number("fskd#jdl.532(iew"); // returns .532

The LWObject Object Agent has had additional functions added. Whereas
you can acquire attribute information using the param() method with a
specifier (POSITION, ROTATION, etc.), you can now use individual methods
to acquire the same information.
getPosition(<time_index>)
getRight(<time_index>)
getUp(<time_index>)
getForward(<time_index>)
getRotation(<time_index>)
getScaling(<time_index>)
getPivot(<time_index>)
getWorldPosition(<time_index>)
getWorldRight(<time_index>)
getWorldUp(<time_index>)
getWorldForward(<time_index>)

|
|
The return value of the LWObject Object Agent method param() (as well as
the individual methods discussed previously) has been altered from three
individual numeric values to a single vector value. This was done to
simplify operations such as comparisons and to reduce memory and
processing overhead by the implicit creation of arrays.
newtime: id, frame, time
{
pivot = id.param(PIVOT,time); // 'pivot' is now a vector
// instead of 'pivot[3]'
...
newtime: id, frame, time
{
pivot = id.getPivot(time); // ditto
...

|
The file() function call has been renamed to File() in order to adhere to
Object Agent creation protocol. The original function name will persist
through this release to allow for time to update existing scripts. The
file() function will no longer exist in the next release of the LScript
engine.
|
|
|
A new layer-management function has been added to LScript for Modeler.
getfull() is the inverse of getempty(), and will return an array of
layers that contain mesh data.
|
|
|
Replacement layer management functions have been added to LScript for
Modeler. Although no new layer functionality is added, these new names
are more standardized in their construction. The existing layer
management functions (getempty(), fglayers(), etc.) will be retired in
the next release of LScript for Modeler, so please update scripts
appropriately.
New Name Obsolete Name
lyrfg() fglayers()
lyrbg() bglayers()
lyrdata() getfull()
lyrempty() getempty()
lyremptyfg() getemptyfg()
lyremptybg() getemptybg()
lyrswap() swaplayers()
lyrsetfg() setlayer()
lyrsetbg() setblayer()

|
The NONPLANAR option to selpolygon() was not correctly allowing its
numeric argument to be optional. This has been corrected.
|
|
|
The requester control mechanism has undergone an overhaul. New functions
have been added that replace the existing creation functions and bring
new functionality to the scripting interface. The existing control
creation functions addcontrol(), addtext() and all Layout-extended
functions (addrgb(), addcheckbox(), etc.) are now obsolete and will be
removed in the next release of LScript.
Function Argument Application
ctlstring() <title>,<string> Modeler/Layout
ctlinteger() <title>,<integer> Modeler/Layout
ctlnumber() <title>,<number> Modeler/Layout

|
Random number generation in LScript has been altered to create a wider
dispersal of numbers for random() calls that happen very close to each
other.
|
|
|
The random() function has been enhanced to accept and return negative
integer values as well as positive.
|
|
|
The save() and load() UDFs were not functioning properly when called for
binary files (as is the case with LScript Procedural Texture). This has
been corrected.
|
|
|
The LScript Image Filter architecture now has two new functions
available, for use during image caching (see cache()). getpixel() and
putpixel() allow direct column and row access to pixel data. These
functions only operate if image caching is enabled.
Function Argument Return
getpixel() <col>,<row> red,grn,blu,alpha
putpixel() <col>,<row>,<red>[,<grn>[,<blu>[,<alpha>]]] none
|
|
|
The round() function has been corrected/enhanced to accept a second, non-
optional integer parameter to indicate the number of decimals of
precision to be retained. A value of '0' indicates that the provided
number is to be rounded up to the nearest whole number.
i = round(45.3465,2) // returns '45.35'
|
|
|
A new function called angle() has been added to LScript. This function
will return the angle, in degrees, between two points on a specified
plane (XZ, YZ, or XY). It accepts two vectors representing the two
points, and a third parameter that specifies the axis perpendicular to
the plane in which the angle should be calculated.
...
editbegin();
pnt1 = pointinfo(points[1]);
pnt2 = pointinfo(points[2]);
editend();
info(angle(pnt1,pnt2,X), // return angle in the YZ plane
" degrees");
...
|
|
|
The selpoint() and selpolygon() functions have been enhanced to accept
arrays or initialization blocks of index or identifier values when the
POINTID, POINTNDX, POLYID, or POLYNDX selection tags are used.
...
selmode(USER);
count = editbegin();
a[1] = points[1];
a[2] = points[count];
editend();
selpoint(SET,POINTID,a); // select first and last points
...
...
selmode(USER);
selpolygon(SET,POLYNDX,@1,3,5@); // select polygons 1,3 and 5
...
|
|
|
Corrected the engine to allow point and polygon ids to be used in
initialization blocks.
|
|
|
Corrected target-name construction for the LSC-LW compiler on the Mac
and Sun platforms.
|
|
|
Corrected memory release problems with the LSC-LW and LSC-MD compilers.
