Method Detail

isAnimation

protected boolean isAnimation()

Description copied from class: PActivity

Return true if this activity is performing an animation. This is used by the PCanvas to determine if it should set the render quality to PCanvas.animatingRenderQuality or not for each frame it renders.

Overrides:

getPositions

public java.awt.geom.Point2D[] getPositions()

getPosition

public java.awt.geom.Point2D getPosition(int index)

setPositions

public void setPositions(java.awt.geom.Point2D[] positions)

setPosition

public void setPosition(int index,
                        java.awt.geom.Point2D position)

setPositions

public void setPositions(java.awt.geom.GeneralPath path)

setRelativeTargetValue

public void setRelativeTargetValue(float zeroToOne,
                                   int startKnot,
                                   int endKnot)
