[font=Times New Roman]As a simple exercise I wanted to create a movie in which the contents of an input text field in frame 1 would be displayed as part of the vapour trail of a jet – So when a user entered their name in the text field & pressed a button we would go to frame 2 where a “Welcome Message” would spell out the visitors name, which would slowly disappear as per a real vapour trail.[/font]
[font=Times New Roman]Although I have had no problems creating & placing the text I have had a lot of grief in getting the trail to dissipate. Knowing that one has to use the “embedFonts” option & have a instance of the selected font somewhere in the movie to get the _alpha property to work I have tried to cover all bases with the following code & placing a “static field” in frame 2 off stage. To keep things simple while sorting out the _alpha problem I have just used code to set it once to 10 rather than the “fading” effect.[/font]
function go(){this._x+=10;
}
plane_mc.onEnterFrame=go;
my_fmt=new TextFormat();
my_fmt.size=50;
my_fmt.color="0x6638D1"
my_fmt.font="Kristen ITC";
count=0;
stop=setInterval(place,1000);
function place(){
nowx=plane_mc._x;
nowy=plane_mc._y;
var thisOne="f_"+count;
thisOne.embedFonts=true;
_root.createTextField(thisOne,count,nowx,nowy,80,80);
thisOne=_root[thisOne]
thisOne.text=input.charAt(count);
thisOne.setTextFormat(my_fmt);
thisOne._alpha=10;//Simplified to just setting _alpha for testing.
count++;
if(count>=input.length){
clearInterval(stop);
}
}
