flash.filters.GlowFilter

[zee644]

hey,

I made this simple glow effect on a mc called glow_mc.
this is the action script:

import flash.filters.GlowFilter;
var gf:GlowFilter = new GlowFilter(0xfffff1, 100, 1, 3, 5, 3, false, false);
glow_mc.filters = [gf];
glow_mc.onEnterFrame = function() {
this.onEnterFrame = function() {
if (gf.blurX <20) {
gf.blurX++;
gf.blurY++;
} else {
delete this.onEnterFrame;
}
glow_mc.filters = [gf];
};
};



my question is, how can i make the glow fade (reduce blur) after it reaches the full blur (20)

a stobing effect is what I am going for...does anyone follow here? help!

[GenCode]

how about a Boolean? that sets to 1 when gf.blur reaches 20.

if(boolean == false){
if (gf.blurX <20) {
gf.blurX++;
gf.blurY++;
} else {
boolean = true;
}else if (boolean == true){
if (gf.blurX >15) {
gf.blurX--;
gf.blurY--;
}else{
delete this.onEnterFrame;
}

well, i couldnt get what you suggested to work exactly, probably just because I couldnt adapt it quite right..anyways here's where I have taken it, i think I am getting closer to the right idea but still not quite there...help?

import flash.filters.GlowFilter;
var zee

var gf:GlowFilter = new GlowFilter(0xfffff1, 100, 1, 3, 5, 3, false, false);
glow_mc.filters = [gf];
glow_mc.onEnterFrame = function() {
if(gf.blurX==1) {
zee = false;
}
if(zee == false){
if (gf.blurX <20) {trace(zee);
gf.blurX++;
gf.blurY++;
}else {
delete this.onEnterFrame;
}
}
if(gf.blurX==20) {
zee = true;
}
if (zee == true){trace(zee);
if (gf.blurX >1) {
gf.blurX--;
gf.blurY--;
}else {
delete this.onEnterFrame;
}
}
}


I actually dont really get why this doesnt work..when i do the trace it says
true
true
true
false
false
false etc...so its switching back and forth, its just not doing what its supposed to when zee= true or false

[zee644]

ok i kinda got it, it works but it doesnt look quite as smooth as it should...any further suggestions?

import flash.filters.GlowFilter;
var zee

var gf:GlowFilter = new GlowFilter(0xfffff1, 50, 1, 3, 5, 3, false, false);
glow_mc.filters = [gf];
glow_mc.onEnterFrame = function() {


if(gf.blurX==1) {
zee = false;
}

if(zee == false && gf.blurX <50) {
gf.blurX++;
gf.blurY++;
trace(gf.blurX)
}

glow_mc.filters = [gf];

if(gf.blurX==50) {
zee = true;

}

if (zee == true && gf.blurX >1) {
gf.blurX--;
gf.blurY--;
trace(gf.blurX)

}
glow_mc.filters = [gf];
}

Use the tween class with filters, much easier to do, and you can achieve more effects:

import flash.filters.GlowFilter;
import mx.transitions.Tween;
import mx.transitions.easing.Regular;
glow_mc.glow = 0;
var tween_glow:Tween = new Tween(glow_mc, "glow", Regular.easeOut, 0, 20, 1, true);
tween_glow.onMotionChanged = function()
{
    var gf:GlowFilter = new GlowFilter(0xFFFFF1, 100, this.obj.glow, this.obj.glow, 5, 3, false, false);
    var filter:Array = new Array(gf);
    this.obj.filters = filter;
};
tween_glow.onMotionFinished = function()
{
    this.yoyo();
};

try to use the filter managing prototypes (FMP) www.flash-fmp.de additionally!
it really simplifies tweening issues with filters a lot, since it converts all filterproperties
to "native" movieclip properties ( similar to e.g. _x, _y or _alpha )

import flash.filters.GlowFilter;
import mx.transitions.Tween;
import mx.transitions.easing.Regular;
glow_mc.glow = 0;
var tween_glow:Tween = new Tween(glow_mc, "glow", Regular.easeOut, 0, 20, 1, true);
tween_glow.onMotionChanged = function()
{
    var gf:GlowFilter = new GlowFilter(0xFFFFF1, 100, this.obj.glow, this.obj.glow, 5, 3, false, false);
    var filter:Array = new Array(gf);
    this.obj.filters = filter;
};
tween_glow.onMotionFinished = function()
{
    this.yoyo();
};

This works great, but how do you stop this function ?
