Display:waveScale{}

Type      [gd]	method of Display class
Overview	wave scale sinusoidally
Return value	self (display object itself)
See also    [bl	Display, display:waveScaleX(), display.waveScaleY()

Syntax

display_obj:waveScale {     peakScale=n1, -- peak scale (default: 1.2)     period=ms, -- period of the sin function (default :1000)     loops = n2, -- number of repeatition (default: INF)     onEnd = function, -- function when called all the iterations are ended }

    All the elements have default values, this method can be called without

any argument.

Note that

    dobj:waveScaleX()

    dobj:waveScaleY()

methods are also defined and use the same parameter table of waveScale() method while

waveScaleX() method changes the x-axis scale only, and

waveScaleY() varies the y-axis scale only.

Examples

local sun = Image('sun.png') sun:waveScale()

local sun = Image('sun.png') sun:waveScale{peakScale=1.1, period=2000}

local sun = Image('sun.png') sun:waveScaleX{loops=3, onEnd=function() print('ended') end}
