My 'For' loop doesn't work
« on: May 24, 2008, 05:28:48 PM »

Hi

I have a 'For' loop in a Window to fade music out:

for(a=100; a<1; a=a-1)
  {
  Game.Msg("MusicFade"+a);
  Game.SetMusicChannelVolume(3, a);
  Sleep(100);
  }
Game.StopMusicChannel(3);

I've made it extreme - a ten second fade - just to check it. It jumps straight to the 'Stop' - I get nothing from the Game.Msg so it's not going through the loop at all.

I guess I must have made some stupid syntactical error. I hope someone can spot it because it will probably also explain why my Static fades don't work either;

TextAlone = this.GetControl("TextAlone");
TextAlone.Visible = true;
TextAlone.AlphaColor = MakeRGBA(255,255,255,1);
// Fade up
for(a=1; a<256; a=a+1)
  {
  WMLogo.AlphaColor = MakeRGBA(255,255,255,a);
  TextAlone.AlphaColor = MakeRGBA(255,255,255,a);
  Sleep(5);
  }
  Sleep(1000);
//  Fade down
for(a=255; a<1; a=a-1)
  {
  WMLogo.AlphaColor = MakeRGBA(255,255,255,a);
  TextAlone.AlphaColor = MakeRGBA(255,255,255,a);
  Sleep(5);
  }
TextAlone.Visible = false;

Cheers

It should be:

for(a=100; a>1; a=a-1)

It says:

1) set the a variable to 100
2) as long as a is bigger than 1...
3) decrease a by one

Ah, I think I get it - I was looking at the middle parameter as though it were a boundary and I need to think of it as being more like a 'while' condition.

That's a conceptual hangover from my 'BASIC' days, I suspect - 'for x=1 to 10... next x'

Thanks again

You were right, that sorted out the Music fade.

What can't understand is why the Static fades don't work. I've checked the code with fades I have in scenes where I'm fading a node in and out and it seems the same. It just doesn't seem to work in the Window. What have I missed?

Forgot to add the code

var GameLogo = this.GetControl("GameLogo");
GameLogo.Visible = true;
GameLogo.AlphaColor = MakeRGBA(255,255,255,1);
for(a=1; a<256; a=a+1)
  {
  GameLogo.AlphaColor = MakeRGBA(255,255,255,a);
  Sleep(5);
  }
  Sleep(1000);
for(a=255; a>1; a=a-1)
  {
  GameLogo.AlphaColor = MakeRGBA(255,255,255,a);
  Sleep(5);
  }
GameLogo.Visible = false;

The static appears and disappears, but does't fade. It works fine in Scenes.

That's because controls don't support AlphaColor changing. Only entire windows can be tinted or made semi-transparent.

Ah - the AlphaColor attribute is listed in the documentation as being used with Static controls. Sorry if I've misunderstood that entry.

Can I put that capability on the wish list please?
