type Artist 

type Artist interface {
	Draw(scr *MultiAgentMonitor, agents []*node)
}

Artist represents somethat that can draw agents into the scene.

type BeamAnimation 

type BeamAnimation struct {
	// contains filtered or unexported fields
}

BeamAnimation represents the source and destination vectors of a beam for node and data visualization in the map view.

type BusArranger 

type BusArranger struct {
	// contains filtered or unexported fields
}

BusArranger defines the width and padding of a visualization bus. A bus allows users to visualize data flow in the core system.

func NewBusArranger 

func NewBusArranger() *BusArranger

NewBusArranger creates a default BusArranger.

func (*BusArranger) Arrange 

func (b *BusArranger) Arrange(nodes []*node, screen_w, screen_h int)

Arrange organizes and arranges nodes (representing agents) on the screen in a multiagent monitor.

type BusArtist 

type BusArtist struct{}

BusArtist generates the graphics representing agent nodes on the bus.

func (*BusArtist) Draw 

func (b *BusArtist) Draw(scr *MultiAgentMonitor, nodes []*node)

Draw generates the graphics representing agent nodes on the bus. This breaks any convenient reuse of the draw interface

type Drawable 

type Drawable interface {
	Draw(tcell.Screen)
}

Drawable represents something that can draw itself into a scene.

type MultiAgentMonitor 

type MultiAgentMonitor struct {
	tcell.Screen

	Windows   []*Window
	Active    int // Current agent being controlled
	ScreenIdx int // Currently shown screen
	// contains filtered or unexported fields
}

MultiAgentMonitor is the primary on-screen visualization structure for core.

func NewMultiAgentMonitor 

func NewMultiAgentMonitor() *MultiAgentMonitor

NewMultiAgentMonitor creates a new MultiAgentMonitor for the current core run.

func (*MultiAgentMonitor) AddWindow 

func (s *MultiAgentMonitor) AddWindow(name string, stdin io.Reader) *Window

AddWindow adds a window to the MultiAgentMonitor.

func (*MultiAgentMonitor) Draw 

func (s *MultiAgentMonitor) Draw(elapsed float64)

Draw is a convenience function that calls on different draw functions based on the screen index (i.e. currently shown screen).

func (s *MultiAgentMonitor) InitializeMapView(names []string)

InitializeMapView creates an initialized map view from a slice of node names.

Map views perform actions:

  1. arrange agents (sets state of graph)
  2. connect agents (draw any background dependent on agent position)
  3. draw "sends" (illustrate or update any "pew pew" information)
