RedPendulum an object that oscillates

superclass: RedObject

note that size is used as radius for this object. works only in 1-2D for now.

see also [RedObject]

instance methods:

addForceAngular2D(force)

push the pendulum with a scalar force.

pendulumOffset2D

return the current location (RedVector2D) of the pendulum relative to the whole object.

pendulumLoc2D

return the actual location (RedVector2D) of the pendulum.

addForceAngular1D(force)

pendulumOffset1D

pendulumLoc1D
