#always_redraw? ⇒ Boolean Also known as: always_redraw

For performance, fixed Particles and SpringConstraints don’t have their paint() method called in order to avoid unnecessary redrawing. A SpringConstraint is considered fixed if its two connecting Particles are fixed. Setting this property to true forces paint() to be called if this Particle or SpringConstraint fixed property is true. If you are rotating a fixed Particle or SpringConstraint then you would set it’s repaintFixed property to true. This property has no effect if a Particle or SpringConstraint is not fixed.

Returns:

  • (Boolean)
