Stopping a loop

[Wookie]

I have a fade effect, ie an image fades into view and then out of view using this code in the "on Timer"

if Opacity<=10 then
step=2;
elseif Opacity >=250 then
step=-2;

end

Opacity=Opacity+step;
long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL);

The trouble is I want it to fade into view and then out of view once only, and then to fade into my main application...how do I stop this looping I am getting and then launch my main application?

TIA

Anyone?

I have spent all day going through the scripting guide to find something that will solve my problem above. I cannot see anything there, can someone please offer some help or advice?

Hey, try using the 'break' control word which is in the scripting guide.

pretty sure it's used for exactly that... breaking out of loops etc.

thats my 2 cents..hope gets you somewhere

Yeah I have tried that in various forms, but then the build fails as it says there is no loop to break...

But thanks for trying, I appreciate that!

Very busy weekend. Try something like this.

[On Show]
direction = up
Opacity = 0
Page.StartTimer(50);

[On Timer]

if direction == up then
  if (Opacity < 255) then 
    Opacity = Opacity + 2
    long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL); 
  elseif Opacity >=255 then
    direction = down
  end
elseif direction == down then
  if (Opacity > 0) then 
    Opacity = Opacity + 2
    long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL); 
  elseif (Opacity <= 0) then 
    Page.StopTimer()
  end
end

Hey wow, neat code pasting thingy.

Thanks TJ..I have tried that one now and I'm afraid it does not work.

I get half of what I want ie, the image will fade from nothing to full view, then it just dissapears completely.

Thanks once again TJ...I appreciate the time and effort you spent trying this one out for me.

change + to - in second part of the code

elseif direction == down then
if (Opacity > 0) then
--Change
Opacity = Opacity + 2 -> Opacity = Opacity - 2
---------
long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL);
elseif (Opacity <= 0) then
Page.StopTimer()
end
end

Thanks Stefan...I have already tried that one....and I get the same result as above...in other words just half of the effect that I want.

I'll have to try again later, I'm off to bed now...

Thanks ALL of you who have tried this out for me...the saga continues!

Try to enclose the direction parameters in ""

[On Show]
direction = "up"
Opacity = 0
Page.StartTimer(50);

[On Timer]
Code:
if direction == "up" then
if (Opacity < 255) then
Opacity = Opacity + 2
long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL);
elseif Opacity >=255 then
direction = "down"
end
elseif direction == "down" then
if (Opacity > 0) then
Opacity = Opacity + 2
long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL);
elseif (Opacity <= 0) then
Page.StopTimer()
end
end

Nice one Stefan, its now mostly working.

My image fades from nothing to full opacity, then dissapears for a second then reappears at full opacity and fades away to nothing. I'm not sure why it dissapears...any ideas?

Thanks again Stefan!

copy paste error
change + to - at second part of code
change elseif to else

[On Timer]
Code:
if direction == "up" then
if (Opacity < 255) then
Opacity = Opacity + 2
long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL);
elseif Opacity >=255 then
direction = "down"
end
elseif direction == "down" then
if (Opacity > 0) then
Opacity = Opacity - 2
long = DLL.CallFunction("AutoPlay\\Docs\\wTrans.dll", "SetWindowTransparency", handle..","..Opacity, DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL);
else
Page.StopTimer()
end
end

I had already changed the + to a -, and making the elseif to else change did not change the way the app worked.

How do I save or publish this little app so I can attach it here for you all to view and tinker with?

Here is a copy of the logo...Please bear in mind that I plan to make a better looking logo later on...

Hope this helps you to help me..
