- Introduction
- -----------------------------------------------------------------
-
- Dust operates on different kinds of structures:
- objects, particle-objects, windows, textures and brushes.
-
- Every structure can be reached specifiing its identifier, there
- are the following identifiers:
- objectID, particleID, windowID, textureID and brushID.
-
- Dust is a kind of a programming language so it interpretes
- commands, knows mathematical expressions, global variables
- and can perform loops.
-
- All commands have an unique structure:
- identifier([<argument1>[,<argument2>[,...]]]).
- Identifiers are lower case, arguments enclosed in "[" and "]" are
- optional.
-
- All numeric arguments can be omitted as mathematical expressions
- containing global variables, rounding is done automatically, e.g.
- "load(4/3,obj)" is identical to "load(1,obj)".
-
- You can define global variables using the CALC-command or the
- online-calculator-mode, e.g.:
- "calc("a=3*sin(46")".
-
- Strings, e.g. filenames can contain special format-characters.
- If a Dust-command recognises such a format-character it inserts the
- recent value of the loop-counter. The loop-counter is equal to the
- loop-variable of the innerst FOR-loop or the value ACTVAL outside of
- loops.
- Example:
- "load(1,obj.%)" will load "obj.0034" if the loop-counter is 34.
-
-
- If you want to lineracombine some F/X you will need loops and the
- FRAME-commands.
- Example:
- The command
- "XYZ(<objectID>,<n>,<filename>)"
- performs such an effect creating n objects. In case of a linear-
- combination it's not necessary to save all object to disk.
- Usually there is a complementary command of the structure
- "XYZFRAME(<objectID>,<n>,<i>,<dest>)" which only creates the
- i-th object of the sequence and stores it to buffer dest.
- For more explanation the example-script "interfere.bat".
