hello…
I have problem about combobox.
I have one combobox and in labels “Underdamped,Overdamped,Undamped,Crittally damped”
I want then select “Crittally damped” in combobox .It plot graph red line and then I select “Underdamped” it show plot graph blue line and red line dont lost.
first then select “Crittally damped”
two then select “Underdamped”
this is code
this.createEmptyMovieClip(“graph_mc”,this.getNextHighestDepth());
this.createEmptyMovieClip(“graph1_mc”,this.getNextHighestDepth());
this.createEmptyMovieClip(“graph2_mc”,this.getNextHighestDepth());
this.createEmptyMovieClip(“graph3_mc”,this.getNextHighestDepth());
LO = new Object();
LO.change = function(EO)
{
c1Value= c1.getSelectedItem().label;
checkValue();
};
graph_mc.moveTo(100,300);
graph1_mc.moveTo(100,300);
graph2_mc.moveTo(100,300);
graph3_mc.moveTo(100,300);
graph_mc.lineStyle(2,0xff0000);
graph1_mc.lineStyle(2,0xFFFFFF);
graph2_mc.lineStyle(2,0xCCCCCC);
graph3_mc.lineStyle(2,0x0000FF);
var t:Number = 0;
var i:Number =-98;
this.onEnterFrame=function()
{
if(i<148&&c1Value==“Critically damped”)
{
Go=(3Math.exp(-3t)+Math.exp(-3t))/5;
graph_mc.lineTo(201+i,140-260Go/150*i);
t+=1/12;
i=i+3;
}
if(i<139&&c1Value==“Undamped”)
{
G1=(1+Math.sin(3t-19.4));
graph1_mc.lineTo(209+i,300-80G1);
t+=1/20;
i=i+3;
}
if(i<148&&c1Value==“Underdamped”)
{
Go=1.5*(1.06*Math.exp(-t)Math.cos(Math.sqrt(8)t-19.47));
graph2_mc.lineTo(198+i,140-190Go/150i);
t+=1/7;
i=i+3;
}
if(i<148&&c1Value==“Overdamped”)
{
Go=(0.171Math.exp(-7.854t)+1.171Math.exp(-1.146t))/1.8;
graph3_mc.lineTo(202.5+i,140-260Go/150i);
t+=1/12;
i=i+3;
}
}
_root.c1.addEventListener(“change”, LO);
can you help me?
thanks you for help me.
