Hello,

I need your help. I'm not good at programming and I have this little problem:
I'm wondering if it's possible to change the opacity of an entire layer.

Per example, when the player opens a close-up layer, it smoothly becomes visible.
When the player closes it, it smoothly becomes invisible.

I've made a test with the  AlphaColor command :

Code: WME Script

1. on "LeftClick"
2. {
3.   var layer = Scene.GetLayer("closeup_winch");
4.   layer.Active = true;
5.   layer.AlphaColor = MakeRGBA(255, 255, 255, 50);
6.   Sleep (100);
7.   layer.AlphaColor = MakeRGBA(255, 255, 255, 100);
8.   Sleep (100);
9.   layer.AlphaColor = MakeRGBA(255, 255, 255, 150);
10.   Sleep (100);
11.   layer.AlphaColor = MakeRGBA(255, 255, 255, 200);
12.   Sleep (100);
13.   layer.AlphaColor = MakeRGBA(255, 255, 255, 255);
14. }

And the FadeIn command:

Code: WME Script

1. on "LeftClick"
2. {
3.   var layer = Scene.GetLayer("closeup_winch");
4.   layer.Active = true;
5.   layer.FadeIn(500, 255, 255, 255, 0);
6. }

Both didn't work.
Is there anything else I can try?

Or maybe it's just not possible?

Thank you for your help!

Thank you for your answer!

I've spent some time today, studying the flashlight script, but I couldn't find a way to solve my problem.
I'll continue to think about it.
Maybe I'll find the answer later!

Layer has no AlphaColor property as well as has no FadeIn() method.
Try to use such code:

Code: WME Script

1. function SetAlpha(_object, _alpha)
2. {
3.   _object.AlphaColor = MakeRGBA(255, 255, 255, _alpha);
4. }
5.  
6. on "LeftClick"
7. {
8.   var layer = Scene.GetLayer("closeup_winch");
9.   var i;
10.  
11.   for (i=0; i<layer.NumNodes; i=i+1)
12.     SetAlpha(layer.GetNode(i), 0);
13.  
14.   layer.Active = true;
15.  
16.   for (var a=5; a<=255; a=a+50)
17.   {
18.     for (i=0; i<layer.NumNodes; i=i+1)
19.       SetAlpha(layer.GetNode(i), a);
20.     Sleep(30);
21.   }
22. }

Thank you 2.0!

I've tested the code in my game: the result is perfect!
Exactly what I was looking for.
I can't wait to implement it to every close-up layer in the game.
I will also take time to study it so I'll become better in scripting!

Many many thanks for your help!

After more tests, I must admit that, even if the script works perfectly, the result doesn't look good.
The reason is very simple:
On a close-up layer there are a background and several nodes above.
When, per example, the background opacity is set on 100, the nodes are set on 100 + 100 (=the background below) : the opacity level of the nodes is added to the opacity level of the background.

So when the script is executed, the opacity changes like this:
background : 5 / Nodes : 5 + 5=10
background : 55 / Nodes : 55 + 55 = 110
background : 105 / Nodes : 105 + 105= 210
...

The nodes appear 2x faster than the close-up background.
The only way I see to get rid of that problem would be to cut holes in the close-up background and put the nodes exactly above those holes.
But is sounds too complicated.
So I'll just forget about having the close-up fade-in / fade-out.


I have another question about opacity.
Is there a way to change opacity for a subframe?
My heroine is a Japanese girl. So everytime she enters a house, she is supposed to take off her shoes.
My idea was to add her shoes as subframe and put the AlphaChannel to 0 everytime she's inside a house.
So there would be no need to load a new actor.

I've tried to do it this way:

1. I've added a Custom Property to the floor named "xShoes" which values are "shoes" when the character is outside and "feet" when she is inside.

2. On the frames of the actor's animation, I add a subframe of the naked feet and a subframe of the shoes.
Then I add a event called "EventShoes" and I attach this script to the sprites:

Code: WME Script

1. #include "scripts\base.inc"
2.  
3.  
4. ////////////////////////////////////////////////////////////////////////////////
5. //on "event"
6. //{
7. //  ...
8. //}
9.  on "EventShoes"
10. {
11. // get a region the actor is standing in
12. var RegShoes = Scene.GetRegionAt(this.X, this.Y);
13.  
14. var frame = this.CurrentFrame;
15. var subframe01 = frame.GetSubframe (0);
16. var subframe02 = frame.GetSubframe (1);
17.  
18. if (RegShoes!=null)
19.   {
20.    switch(RegShoes.xShoes)
21.    {
22.      case "shoes":
23.          subframe01.AlphaColor = MakeRGBA(255, 255, 255, 0);
24.          subframe02.AlphaColor = MakeRGBA(255, 255, 255, 255);
25.      break;
26.  
27.  
28.      case "feet":
29.          subframe01.AlphaColor = MakeRGBA(255, 255, 255, 255);
30.          subframe02.AlphaColor = MakeRGBA(255, 255, 255, 0);
31.      break;
32.    }
33.    }
34. }

As you can see, I used the script for implementing footsteps sounds.
But I don't really understand how to call SubFrames.

And... nothing happens when I play the game.
My script is obviously all wrong.

Is there a way to fix it?
Or maybe it's just impossible to change the opacity of a subframe?

Thank you!
