Designer Component Guide

This guide documents the Component set distributed with Numerus Designer. Numerus Designer models are constructed out of Components, which are visual tokens that are placed on the Design Canvas.

To place a component on the model canvas:

• Press the left mouse button on the desired Component in the Component Palette.
• Drag the component from the component menu onto the Design Canvas.
• A default name will be provided; Alt-click on the name to change it (or change it in the Property Pane).
• The new component must be programmed; this may require the programming of squibs. See Programming References for a discussion of squib programming.

Basic Components

Command

A command contains code that is executed once per timestep. Commands do not return values; rather they operate by altering simulation state, often through the execution of some primitive operator. One common use for a Command is during program development, where the Console.log primop is used to print useful values to the console. Another important role is in the agent life cycle, where Commands may contain code used to create or terminate agents, or move them in their environment.
