Class VelocityRenderer

java.lang.Object
  net.nexttext.renderer.TextPageRenderer
      net.nexttext.renderer.VelocityRenderer

public class VelocityRenderer
extends TextPageRenderer

Traverses the TextObject hierarchy and draws every object's velocity as a line starting from the object's position. This callback is useful to debug behaviours that make use of the Velocity property.

Constructor Summary

VelocityRenderer(processing.core.PApplet p, int color, int scale)
Builds a VelocityRenderer.

VelocityRenderer(processing.core.PApplet p, int r, int g, int b, int scale)
Builds a VelocityRenderer.

Method Summary

void	renderPage(TextPage textPage) Traverses the TextObject hierarchy and renders a velocity vector for any TextObject having a Velocity property.

Constructor Detail

VelocityRenderer

public VelocityRenderer(processing.core.PApplet p,
                        int color,
                        int scale)

Builds a VelocityRenderer.

Parameters:

p - the parent PApplet

color - the color that will be used to render the vector

scale - a scalar that will be used to make the vector proportionally larger. This is useful since (x,y) values for velocity are often in the range 0~5.

VelocityRenderer

public VelocityRenderer(processing.core.PApplet p,
                        int r,
                        int g,
                        int b,
                        int scale)

Builds a VelocityRenderer.

Parameters:

p - the parent PApplet

r - the red value of the color that will be used to render the vector

g - the green value of the color that will be used to render the vector

b - the blue value of the color that will be used to render the vector

scale - a scalar that will be used to make the vector proportionally larger. This is useful since (x,y) values for velocity are often in the range 0~5.
