Sierpinski’s fractals demo

This demo is about Sierpinski’s fractals. Those are 3 triangles inside a triangle.

Launching the demonstration

• From SARL ID:
  1. Create a launch configuration of type “SARL Application”
  2. As the main class, select io.sarl.demos.sierpinskiFractals.SierpinskiFractals
• From command-line interface:
  1. Launch the application as a standard Java program.

Description of the software

In the Sierpinski’s fractals, there are 3 triangles inside a triangle.

To create this demo, only one agent was required. The idea is to create a main agent and then create 3 other agents in the inner context of the main agent. Then the main agent becomes an event broadcaster and so on and so forth for each fractals newly created.

agent Fractal {
	...

	on Initialize {
		if (occurrence.parameters.size >= 2){
			// If initialized with arguments

			screenSurface = occurrence.parameters.get(0) as Square
			positions = occurrence.parameters.get(1) as Positions

			if (occurrence.parameters.size.equals(3)){
				// If initialized by the GUI
				var ctrl = occurrence.parameters.get(2) as FXMLViewerController
				guiSpace =  defaultContext.createSpace(
					OpenEventSpaceSpecification, UUID.randomUUID)
				ctrl.setGUISpace(guiSpace)
				guiSpace.register(asEventListener)
			}
		} else {
			// If initialized without argument
			screenSurface = new Square
			positions = new Positions
		}
		screenWidth = screenSurface.width
		this.generatePoints
	}

	...

}

MVC pattern

This application follows a MVC (Model-View-Controller) pattern for the GUI communication.
