Abstract
A method and apparatus for constructing subroutines to define the behavior of simulation objects is provided. The apparatus includes a display, a processor, and an input device. The processor generates on the display a GRR set region associated with a simulation object. A user operates the input device to place visual representations of rules and/or subroutines within the GRR set region. When a visual representation of a rule or subroutine is placed within a GRR set, computer step sequences that implement the behavior specified for the rule or subroutine are generated for the simulation object. A user may operate the input device to activate a control on a visual subroutine indicator to cause a subroutine region to appear. When a visual representation of a rule or subroutine is placed within a subroutine region, the behavior specified for the rule or subroutine is incorporated into the subroutine associated with the subroutine region. Different types of subroutines are provided, where the type of a subroutine determines how the rules within the subroutine are processed during a simulation. Pretests may be specified for subroutines so that the behavior represented by the rules withi…
