Topic: Pixel based transparency effect

[newwaveburritos]

My game is not a true 8 bit game but I do use the sixteen color palette exclusively as as an aesthetic decision.  Thus, using character fade outs and ins kind of feels like cheating to me.  When I import a sprite it has a transparency mask already so I'm wondering if there's a way to randomly replace pixels in the sprite with this transparency mask one by one until the whole sprite is then transparent.  This would look a lot better to my eye than having a character fadeout like from the manual:

Code: [Select]

int trans = cEgo.Transparency;
while (trans < 100) {
  trans++;
  cEgo.Transparency = trans;
  Wait(1);
}

Thanks, everybody!

I was interested with your idea so I thought i'd try it.I didn't get it to work the way I was doing it but if you would like to try to get what I have to work here it is.

Code: Adventure Game Studio

1. int pixwide;
2. int pixheight;
3. int coverpixelplaced;
4. function room_AfterFadeIn()
5. {  
6.        
7. }
8.  
9. function room_RepExec()
10. {
11.         player.Baseline=-2000;
12.         pixwide = Random(Game.SpriteWidth[2000]);
13.         pixheight=Random(Game.SpriteHeight[2000]);
14.         DynamicSprite* draw;
15.         if(coverpixelplaced==Game.SpriteWidth[2000]||Game.SpriteHeight[2000])
16.         {
17.                 //draw.Delete();
18.                 //way to make character invisible;
19.         }      
20.         else
21.         {
22.                 draw=DynamicSprite.CreateFromBackground(0,player.x+pixwide, player.y+pixheight, 1,1 );
23.                 coverpixelplaced+=1;
24.         }
25. }
26.

I made a module:
https://drive.google.com/file/d/1AMUHSUMq_xoszQBP6WUbxCZNVvQb4_7Y/view?usp=sharing

void Character.PixelFade(FadeType fadeType, int width, int speed)

FadeType is eFadeOut or eFadeIn.
width is the width of a single strip of pixels that grows transparent; try a value like 10
speed is the number of frames in between single pixels, use a low number like 3 (smaller number -> faster fading)

Oh wow!  This is amazing and exactly what I meant.  So, I guess that no there is not really an easy way to do it but there is certainly a way.  Thanks so much for putting that together.
