Summary |
A keyword used with function variables: ^[funcname parameter(s)]. This syntax can be used anywhere that a regular 3B2 variable can be used: in show strings, in scripts, in expressions, etc. Function variables are a V8 feature that uniforms variable use and functions into a readable syntax. The 'measure' function converts the given measure into 3B2's own internal unit of measure 'deci microns', generaly used to subsequently perform some other action on the value. |
