LDFastArray
This object provides another faster way of storing values in an Array.
It can handle 1, 2, 3 and higher dimensional arrays and has methods to read and write arrays to files, including in CSV format.
It is also possible for different rows in an array to have different dimensions or numbers of elements (jagged array), just like Small Basic arrays.
Internally it uses lists that allow the sizes to grow so that the array dimension or size doesn't need to be set at the start.
The indexing is by integer starting from 1.
For 1D arrays it is recommended to use LDList since it has additional sort methods.
Elements in arrays with dimension greater than 3 are indexed by a comma separated list of indices or index variable names.

LDFastShapes
Shape methods which are faster than standard Small Basic Shape operations.
This is primarily for shape movement when there are a large number of shapes updated in a game loop.
Only the main Shapes commands are supported since these are the ones that are commonly repeated many times.
The shape must first be created, then registered (ShapeIndex) and the returned integer index used with the other methods.
The visual update of the changes made does not happen until (Update) is called when all changes are processed together.
Performance improvements come from both integer indexing and batch update.

Reposition(scaleX,scaleY,panX,panY,angle)
Scale and move all Shapes and Controls within the GraphicsWindow.
This method resizes and moves the view rather than the shapes, so their positions and other properties remain unchanged but appear scaled within the repositioned region.
For example Shapes.GetLeft remains unchanged although the view has been repositioned and GraphicsWindow.MouseX reports the coordinates relative to the repositioned view.
Imagine the entire view is repositioned as if it were a shape inside the GrapicsWindow.
The transformation between view coordinates (vX,vY) and GraphicsWindow coordinates (gwX,gwY) is:
gwX = (vX+panX)*scaleX + gw*(1-scaleX)/2
gwY = (vY+panY)*scaleY + gh*(1-scaleY)/2
All drawing remains within the original GraphicsWindow.

LDInline
Include C#, VB or JScript code to use at runtime.
If multiple namespaces or classes are used, then all method, property or event names should be unique.
Alternatively a fully qualified namespace.type.name may be used.
Can be used to compile extensions.
May also be used with other .Net dlls compiled externally.
Method, property, event, class and used references can be obtained (public static only).
The current application assemblies are auto referenced.
Depending on .Net methods used additional assemblies may be required.
Additional assemblies are referenced by full dll path.
Assembly dlls are often found in the following or similar locations:
C:\Windows\Microsoft.NET\Framework\v2.0.50727
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.0
The TextWindow should be visible prior to using these methods if later use of the TextWindow is required.

Help()
This function is just to display this help.
The extension uses Box2D (http://box2d.org) as an engine and provides an interface between it and the graphics capabilities of SmallBasic.
Only shapes that are connected to the physics engine take part in the motion physics, for example you may add normal shapes (e.g. a gun and not connect it to the physics engine). Once a shape is connected to the engine, it is best to only interact with it through the methods provided by the extension. All positions are in the SmallBasic GraphicsWindow pixels and refer to shape centres.
Image and text shapes are treated as rectangles, and ellipses as circles; there is also triangle and convex polygon support, but not lines. Images may be treated as circles by setting the property LoadImagesAsCircles to "True".
One issue that Box2D has difficulty with is small fast moving objects that can 'tunnel' through other shapes without being deflected (see the SetBullet option).
Another problem is shapes of very different size and hence mass, especially large shapes when they are connected together. It may be necessary to modify the density for these (the Anchor options are an attempt to automate this a bit), otherwise the default density of 1 is good. Resist the temptation to connect too many shapes together.
It may be possible to improve the stability of some 'difficult' models using the TimestepControl settings, but the defaults look good for most cases.
Do not call the physics methods inside SmallBasic event subroutines directly, rather set flags that can be processed in a main game loop.
There are sample SmallBasic programs and a Getting Started Guide that comes with the extension dll - this is the best place to start.
Report bugs and problems to the SmallBasic forum (http://social.msdn.microsoft.com/Forums/en-US/smallbasic/threads), but first simplify your SmallBasic code to isolate the issue before providing a short 'runnable' code sample.

LDUnits
A general editable unit conversion system.
All units and dimensions are case sensitive.
A base unit consists of a single dimension and name, and are all independent.
A derived unit consists of a description, name and units definition consisting of base or other derived units, and optional additive term, usually 0.
A unit is parsed by separting . / + - and *, then recursively resolving derived unit conversions, bracketed () terms first.
Values (especially those with a decimal point '.' or minus '-') should be contained in ().
A unit may be prefixed by a prefix or number value (e.g. m is mili 0.001, K is kilo 1000 etc).
Any unit may be postfixed by a power.
A typical unit may be "mile/hr", "m/s2" or "MJ/day" etc and can be any combination of base and derived units.
Any pair of unis that are dimensionally the same can be converted.
An additive value is only used for non-compound unit conversions (e.g. C to F).
To avoid obscure prefix unit conflicts use a full prefix name (e.g. min could be 60 seconds or 0.001 inches, the latter should be milliin).
Currency conversions are updated daily.
