fade out screen, sprites, models, .lmps

[behind_you]

ive been wondering about this for a while now. how can this be done?

[ceriux]

a sprite you would just need multiple frames, one that started solid, then as time goes it changes frames of it fading, till there's nothing visible then remove the sprite .

[Mexicouger]

Or implement Scale, alpha, and glow for models in a tutorial, and just make the entity think about fading itself out of the game(eventually removeing itself)

i tried your idea ceriux, but when the sprite fades out, the pink transparent color mixes in the background mixes with the image color. the engine no longer recognises the color as pink and it doesn't look transparent anymore.

can you explain a little more mexicouger.


thanks to everyone!

[ceriux]

if your's is a sprite, it's because the pink you're using is off, or the palette your using is one of the two.

[behind_you]

um nooooo. when my sprite is not fading, the pink shows as transparent. when it fades, the pink behind the picture of the fading model (i use photoshop) isn't recognised as pink and it appears.

[ceriux]

i used the same method, seemed to work fine for me.

1. What engine are you using?
2. Are you saving alpha channel properly?

The best solution by the way isn't to create new sprite frames, it's to use the .alpha QuakeC field, which works on both sprites and models, but doesn't exist in the vanilla Quake engines, only in modified engines like DarkPlaces.

can u give me an example or alpha being used?

first you need to write in defs.qc
.float alpha;

and for example yo can put the value in

void() BecomeExplosion =
{
self.movetype = MOVETYPE_NONE;
self.velocity = '0 0 0';
self.touch = SUB_Null;
setmodel (self, "progs/s_explod.spr");
self.solid = SOLID_NOT;
self.alpha = 0.4;// 0 is invisible, 1 is totally visible
s_explode1 ();
};

wow, nd that's all? Thanks!

Does that fade out in timing or make it transparent only?

alpha channel !!!!!!!!!!!!
hahahahahaha
sorry
I don´t read anything,
You can use the gimp 2 for that, and use external textures for the sprite.
Gimp 2 is the best program you just have to remove the layer and then it gives you the transparency.
transparency can put on your sprite.


Then you must rename the image. (I use tga)
For example I use the bubble.
the original name s_bubble.spr
so that's Darkplaces'll recognize the name
s_bubble.spr_0.tga
Where 0 is the frame number.
let the new image where is the original sprite (in this case the folder progs)
and we have so

sorry
i didn´t understand the question, my english is very very bad
I need learn.

[behind_you]

ok nahuel. I mean making a model start not faded and then it slowly fades out until it becomes invisible. How can i do that?

oh very well, I made something similar but with a sprite
let's suppose that you want to do that, (for example)the demon whenever it jumps becomes more and more transparent.

void() demon1_jump1 =[ $leap1, demon1_jump2 ] {ai_face();
self.alpha = 1;
};
void() demon1_jump2 =[ $leap2, demon1_jump3 ] {ai_face();
self.alpha = 0.95;

};
void() demon1_jump3 =[ $leap3, demon1_jump4 ] {ai_face();
self.alpha = 0.9;

};
void() demon1_jump4 =[ $leap4, demon1_jump5 ]
{
ai_face();

self.touch = Demon_JumpTouch;
makevectors (self.angles);
self.origin_z = self.origin_z + 1;
self.velocity = v_forward * 600 + '0 0 250';
if (self.flags & FL_ONGROUND)
self.flags = self.flags - FL_ONGROUND;
self.alpha = 0.8;

};
void() demon1_jump5 =[ $leap5, demon1_jump6 ] {
self.alpha = 0.7;

};
void() demon1_jump6 =[ $leap6, demon1_jump7 ] {
self.alpha = 0.6;

};
void() demon1_jump7 =[ $leap7, demon1_jump8 ] {
self.alpha = 0.5;

};
void() demon1_jump8 =[ $leap8, demon1_jump9 ] {
self.alpha = 0.4;

};
void() demon1_jump9 =[ $leap9, demon1_jump10 ] {
self.alpha = 0.3;

};
void() demon1_jump10 =[ $leap10, demon1_jump1 ] {
self.nextthink = time + 3;
// if three seconds pass, assume demon is stuck and jump again
self.alpha = 0.2;

};

void() demon1_jump11 =[ $leap11, demon1_jump12 ] {
self.alpha = 0.1;

};
void() demon1_jump12 =[ $leap12, demon1_run1 ] {
self.alpha = 0.05;

};


if you specified already alpha in the defs.qc you can do that one.
Notice that in every frame alpha approaches more 0.
But remember to put alpha =1 in every others of the actions because the demon goes away to do transparently in every action that it comes after the jump.
