[SOLVED]fade In, fade out possessed by demon !

I made this nice code for fade in fade out objects.
To be more exact, you click on an object, text object fades in says something like "You can not go there" and then fades out. It works ok unless you are an impatient person like myself who likes clicking all the time on the same object, and when you start doing it, fade in and fade out start to interfere with each other.
And start blinking since my functions are using getBlendAlpha and setBlendAlpha.
Here is the code

Here is the code
// Here we do fade in text object "You can not go there" and after 2200 ms we schedule fade out
function DoorBlock01 :: onMouseDown (%this, %modifier, %worldPosition, %clicks)
{ // I tried to turn the mouse events off and setMouseEvents back to true in function fadeOutObject1, didnt work
//%this.DoorBlock01.setUseMouseEvents(false);
schedule(200, 0, "fadeInObject1", Dialog01Pt02);
schedule(200, 0, "fadeInObject1", Dialog02Pt02);
schedule(2200, 0, "fadeOutObject1", Dialog01Pt02);
schedule(2200, 0, "fadeOutObject1", Dialog02Pt02);
}
function DoorBlock01 :: onMouseLeave (%this, %modifier, %worldPosition, %clicks)
{
//fadeOutObject1(Dialog01Pt02);
//fadeOutObject1(Dialog02Pt02);
}
function fadeInObject1(%this)
{
//Get the current alpha level of the object and add 0.1 to it.
%alphaLevel = %this.getBlendAlpha() + 0.1;
//Check the alpha level of the object.
if(%this.getBlendAlpha() != 1)
{
//If it isn't 1 then set the object's alpha level to the new alpha level defined before.
%this.setBlendAlpha(%alphaLevel);
//And call a schedule function to re do this function.
schedule(50, 0, "fadeInObject1", %this);
}
}
function fadeOutObject1(%this)
{
//Get the current alpha level of the object and remove 0.1 from it.
%alphaLevel = %this.getBlendAlpha() - 0.1;
//Check the alpha level of the object.
if(%this.getBlendAlpha() != 0)
{
//If it isn't 0 then set the object's alpha level to the new alpha level defined before.
%this.setBlendAlpha(%alphaLevel);
//And call a schedule function to re do this function.
schedule(80, 0, "fadeOutObject1", %this);
}
// I tried adding this
//if(%this.getBlendAlpha() == 0)
//{
// %this.DoorBlock01.setUseMouseEvents(true);
//}
} How to get rid off this nasty bug?

I'm trying your method without succes. Nothing happens and no errors.
It doesn't start fading in.
After that, and I'm not 100% sure, but I think you made few typos with Dialog01Pt02 and Dialog01Pt2.
I correted it all and made a slight change and still nothing happens
Here is my current code:

Here is my current code:
function DoorBlock01 :: onMouseDown (%this, %modifier, %worldPosition, %clicks)
{
// If not fading, begin fading, else stop all fading then begin fading again
if(!isEventPending(Dialog01Pt02.fadingEvent) && !isEventPending(Dialog02Pt02.fadingEvent))
{
Dialog01Pt02.fadingEvent = schedule(200, "fadeInAndOutDialog", Dialog01Pt02, "in");
Dialog02Pt02.fadingEvent = schedule(200, "fadeInAndOutDialog", Dialog02Pt02, "in");
} else
{
cancel(Dialog01Pt02.fadingEvent);
cancel(Dialog02Pt02.fadingEvent);
Dialog01Pt02.fadingEvent = schedule(200, "fadeInAndOutDialog", Dialog01Pt02, "out");
Dialog02Pt02.fadingEvent = schedule(200, "fadeInAndOutDialog", Dialog02Pt02, "out");
}
}
function fadeInAndOutDialog(%this, %direction)
{
// Get variables
%alphaLevel = %this.getBlendAlpha();
// Fade "in" or fade "out"
if( %direction $= "in" )
{
// If not fully opaque, continue fading in, else begin fading out
%alphaLevel = %this.getBlendAlpha() + 0.1;
//Check the alpha level of the object.
if(%this.getBlendAlpha() != 1)
{
//%this.setBlendAlpha( %alphaLevel + 0.1 );
%this.fadingEvent = schedule(50, "fadeInAndOutDialog", %this, "in");
} else {
%this.setBlendAlpha(1); // Make sure it's fully opaque (and not 0.95 or such)
%this.fadingEvent = schedule(2000, "fadeInAndOutDialog", %this, "out");
}
} else if ( %direction $= "out" )
{
// If not fully transparent, continue fading out
if( %alphaLevel - 0.1 >= 0 ) {
%this.setBlendAlpha( %alphaLevel - 0.1 );
%this.fadingEvent = schedule(50, "fadeInAndOutDialog", %this, "out");
} else %this.setBlendAlpha(0); // Make sure it's fully transparent
} else error("Invalid %direction! Object: " @ %this);
}It looks like it even doesn't want to start fading in.

Edit: Surprisingly hard to check code in a forum post.
Then open your console after giving it a shot. It should be working, the only thing I can think of is that it isn't performing this on the right object or is somehow getting into a loop.

Hmm let's see. I did write that code off the cuff, so I may have overlooked something, however it should still work. Let's throw in some echo statements and see what the console says, and we should change "%this" to something else since it isn't a method, try this code:function fadeInAndOutDialog(%object, %direction)
{
echo("Entering fade function, parameters: " @ %object @ ", " @ %direction);
// Get variables
%alphaLevel = %object.getBlendAlpha();
echo("Current alpha: " @ %alphaLevel);
// Fade "in" or fade "out"
if( %direction $= "in" ) {
echo("Fade in: " @ %alphaLevel + 0.1);
// If not fully opaque, continue fading in, else begin fading out
if( %alphaLevel + 0.1 <= 1 ) {
%object.setBlendAlpha( %alphaLevel + 0.1 );
%object.fadingEvent = schedule(50, "fadeInAndOutDialog", %object, "in");
} else {
echo("Faded in");
%object.setBlendAlpha(1); // Make sure it's fully opaque (and not 0.95 or such)
%object.fadingEvent = schedule(2000, "fadeInAndOutDialog", %object, "out");
}
} else if ( %direction $= "out" ) {
echo("Fade out: " @ %alphaLevel - 0.1);
// If not fully transparent, continue fading out
if( %alphaLevel - 0.1 >= 0 ) {
%object.setBlendAlpha( %alphaLevel - 0.1 );
%object.fadingEvent = schedule(50, "fadeInAndOutDialog", %object, "out");
} else {
echo("Faded out");
%object.setBlendAlpha(0); // Make sure it's fully transparent
}
} else error("Invalid %direction! Object: " @ %object);
echo("");

When using schedule globally, I forgot that you need to include a reference object before the function name. I see in your original code you had "0", which works. By putting an object in there, if it were to be deleted, the events would automatically be cancelled, which is nice.
So, this code works (I verified it on my console):

I wouldn't have thought of including fade in and fade out in one function.

Justin! thanks, now it works with no bugs or errors.I wouldn't have thought of including fade in and fade out in one function.
