Parabola Object

The Parabola Object will slide the layer along a parabolic path.

Initialization:

objectName.parabola = new Parabola("objectName","parabola")

Example:

mylayer = new DynLayer("mylayerDiv")
mylayer.parabola = new Parabola("mylayer","parabola")

The play() Method:

The play() method begins the parabola:

objectName.parabola.play(type,distx,disty,xinc,speed,fn)

Where:
• type - 1 is a dropping parabola, 2 is an arcing parabola
• distx - horizontal distance
• disty - vertical distance
• xinc - the number of pixels to move horizontally each repetition
• speed - speed of repetition
• fn - (optional) function or statement to execute when complete

Examples:

mylayer.parabola.play(1,200,200,5,20)

The stop() Methods:

Work the same as in the circle() method. I didn't bother with a pause method cause I can't see it being useful.

objectName.sinewave.stop()
