Hi guys, I've been looking into a similar problem.... I have a mc that I need to smoohtly zoom in and out of and after days (kid you not, I spent like 2 weeks on this now) of searching I came across tweenmax.... even so I couldn't for the life of me figure it out, but the latest code posted by greensock cleared some stuff up. I tweaked it to make it work for my purposes, it's in AS2 + my coding skills aren't great so I expect it contains some duplicate and redundant statements, but it works! this is an extract from my original project, just has the zoom in/out functionality. you will need a mc and 2 buttons on stage. main code: import com.greensock.TweenMax; import com.greensock.easing.*; FastEase.activate([Linear, Quad, Strong]); //not sure if this helps with the default tween? //any comments on fastEase would be appreciated:) _global.base=this; var isMouseDown:Boolean = false; var speed:Number = 1.1; var maxScale:Number = 100; //maximum scaleX allowed var minScale:Number = 25; //minimum scaleX allowed // this is because I'm inserting a bitmap that starts off displayed at 25% mc._xscale=mc._yscale=25; var duration:Number = 0; var CurrentScale:Number = mc._xscale; var newScale:Number=0; this.onMouseDown = function() { isMouseDown = true; } this.onMouseUp = function() { isMouseDown = false; } //////////////////////////////////////////////////////////////////////////// //TWEENS tweenzoomin=function(){ TweenMax.to(mc, duration, {_xscale:maxScale, _yscale:maxScale, useFrames:true}); } //no easing defined - found that default works best.. tweenzoomout=function(){ TweenMax.to(mc, duration, {_xscale:minScale, _yscale:minScale, useFrames:true}); }//no easing defined - found that default works best.. zoomease=function(){ TweenMax.to(mc, duration, {_xscale:newScale, _yscale:newScale, ease:Quad.easeOut, useFrames:true}); } //////////////////////////////////////////////////////////////////////////// killall = function(){//found it necessary to kill all tweens in the project file, though this might work without it TweenMax.killAll(false, true, true); } //////////////////////////////////////////////////////////////////////////// Zoomin button on(press){ this.onEnterFrame = function() { if(isMouseDown){ currentScale = mc._xscale; if(currentScale<(maxScale-15)){//easeing kicks in at 85% of scale duration = Math.abs( (maxScale - currentScale)/ speed ); tweenzoomin(); } else { killall(); newScale = maxScale duration = 8; //8fps zoomease(); } } } } on(release, releaseOutside){ delete onEnterFrame; killall(); currentScale = mc._xscale; if (mc._xscale < maxScale) { newScale = Math.min( maxScale, currentScale + 3); duration = 12 //12fps zoomease(); } } zoomout button on(press){ this.onEnterFrame = function() { if(isMouseDown){ currentScale = mc._xscale; if(currentScale > (minScale+15)){//easeing kicks in below 40% of scale(40 to 25) duration = Math.abs( (currentScale-minScale)/ speed ); tweenzoomout(); } else { killall(); newScale = minScale duration = 8 //8fps zoomease(); } } } } on(release, releaseOutside){ delete onEnterFrame; killall(); currentScale = mc._xscale; if (mc._xscale > minScale) { newScale = Math.max( minScale, currentScale - 3); duration = 12 //12fps zoomease(); } }
