Hello!

Sometimes I have a strange trouble with alpha.

Code: Text

1. w=Game.LoadWindow("scenes\test\w4.window");
2. w.FadeTo(0,1,0,0,0);
3. //e=w.GetControl("1");e=e.GetEntity();e.Rotatable=TRUE;e.Rotate=10;
4. w.Visible=TRUE;
5. w.FadeTo(1000,255,255,255,255);
6. Sleep(10000);
7. w.FadeTo(1000,1,0,0,0);
8. w.Visible=FALSE;
9. Game.UnloadObject(w);

.FadeTo() method is based on window's .AlphaColor property. So it works fine! But when I enable marked line (especially, e.Rotatable=TRUE; operator), the entity always becomes visible, and the changing of .AlphaColor doesn't take effect. If I write e.Rotatable=FALSE; operator, it works fine again. I'm embarassed What the matter? Is trouble in the entity container or something else?

Although, .Rotatable is worked. And .AlphaColor not

Here is the piece of advanced script, attached to window

Code: Text

1. #include "scripts\base.inc"
2.  
3. var a0=255;
4. var r0=255;
5. var g0=255;
6. var b0=255;
7.  
8. method FadeTo(duration,a,r,g,b){
9.   if(a==NULL)a=0;
10.   if(r==NULL)r=0;
11.   if(g==NULL)g=0;
12.   if(b==NULL)b=0;
13.   var tmp=Scene.GetNode("temp_entity");
14.   var t0=Game.CurrentTime;
15.   tmp.AlphaColor=this.AlphaColor;
16.   if(tmp.AlphaColor==NULL||tmp.AlphaColor==0){
17.     a0=255;
18.     r0=255;
19.     g0=255;
20.     b0=255;
21.   }
22.   //Game.LOG("=WINDOW "+this.Name+" FADES=");
23.   //Game.LOG("FROM: "+a0+" "+r0+" "+g0+" "+b0);
24.   //Game.LOG("  TO: "+a+" "+r+" "+g+" "+b);
25.   while(TRUE){
26.     var dt;
27.     if(duration>0)dt=(Game.CurrentTime-t0)/duration;else dt=1;
28.     if(dt<0)dt=0;
29.     if(dt>1)dt=1;
30.     tmp.AlphaColor=0;
31.     tmp.AlphaColor=tmp.AlphaColor*256+a0+(a-a0)*dt;
32.     tmp.AlphaColor=tmp.AlphaColor*256+r0+(r-r0)*dt;
33.     tmp.AlphaColor=tmp.AlphaColor*256+g0+(g-g0)*dt;
34.     tmp.AlphaColor=tmp.AlphaColor*256+b0+(b-b0)*dt;
35.     this.AlphaColor=tmp.AlphaColor;
36.     if(dt==1){
37.       if(a==255&&r==255&&g==255&&b==255)this.AlphaColor=NULL;
38.       a0=a;
39.       r0=r;
40.       g0=g;
41.       b0=b;
42.       break;
43.     }
44.     Sleep(50);
45.   }
46. }

this is some heavy coding. Any reason why you don't use MakeRGBA? Are you sure your alpha color is set properly?

I think alpha works well even for rotated sprites.

I tried rotating an entity and setting its AlphaColor - works ok. I tried the same with an entity embedded into an entity container - also works. If you can make some minimal example exhibiting your problem, I'll look into it.

Thanks for help!

Gya-a! Now I use MakeRGBA()!

Are you sure your alpha color is set properly?

Yes, I'm sure. It's worked fine, when .Rotatable property is FALSE

I tried the same with an entity embedded into an entity container - also works

It's strange. I have bad feelings Maybe, I misunderstand something. Anyway...

Code: Text

1. //e=w.GetControl("1");e=e.GetEntity();e.Rotatable=TRUE;e.Rotate=350;

If I erased "//", the entity turned to angle, but .FadeTo() method broke suddenly. (So "1"'s entity didn't appear slowly)

Code: Text

1. c=w.GetControl("1");
2. e=c.GetEntity();
3. e.FadeTo(0,0,0,0,1);
4. c.Visible=TRUE;
5. e.FadeTo(TIME,255,255,255,255);

Entity .FadeTo() method didn't work at all, when the entity was in the entity container. (.AlphaColor property didn't have any effect)

Links.

The example (temporary file erased)

That was a well disguised bug, thanks for your help. Fixed in the latest build.

[mRax]

Thanks you too

Code: Text

1. e=w.GetControl("1");e=e.GetEntity();e.Rotatable=TRUE;e.Rotate=350;

Now it worked properly.

And what about this?

Code: Text

1. c=w.GetControl("1");
2. e=c.GetEntity();
3. e.FadeTo(0,0,0,0,1);    // entity must be transparent, but it isn't
4. c.Visible=TRUE; // entity container appears "suddenly" (because of the entity is not transparent)
5. e.FadeTo(TIME,255,255,255,255); // entity must fade in from transparent state, but there isn't any action

Did I make a mistake somewhere?

It won't work, because for entity containers their alpha color is overridden by their parent window's alpha color.

[DocBass]

It won't work, because for entity containers their alpha color is overridden by their parent window's alpha color.

Is this still true? I have one window set up like this that I am easily controlling the alphas of entities within entity containers, and another window that is nearly identical that wont allow me to touch the alphas of entities within entity containers. Trying to figure out why is driving me mad. 

[Mnemonic]

Yes, I believe this is still true.
