I need a cross fade script:(

I have been searching for a Cross Fade script. One that fades one texture to another. I need full permissions. If anyone knows of where I can get one I would love you to pieces! TY

It's not really possible to fade a surface from one texture to another, I'm afraid, because SL doesn't let you do multi-texturing (i.e. displaying more than one texture at the same time on the same face).

The best you could do is fake it by having the first texture on a surface slightly in front of the other. You can then simulate the cross-fade by steadily reducing the first surface's alpha (opaqueness) to 0.

I have seen prims with cross fade scripts in them. Im not sure I understand the one texture slightly in front of the other?

It would have to be two seperate prims, the bottom/back one always being opaque the front one cycling alpha value. Pretty much like this:

Prim 1: 100% Picture 1
Prim 2: 100% Picture 2
Prim 1: Fades out (on a timer?) till 0%
Prim 2: 100% (never changes)
Prim 1: Reset to 100%, has Picture 2 applied to it.
Prim 2: Has picture 3 applied to it.

With the fade and handoff always repeating.

it is possible with one prim, darkening the prim and when it goes fully dark the next textureloads and it lightens back again. not really cross fading, but only one prim.

ok Got ya What script would I use to make prim one fade out? Sorry if Im a pest I so appreciate the help.

And TY Renee Im working with what you gave me trying to figure it out

Join Script Academy group, ask the owner Ilse for a crossfade script. She wrote one. Or check group notices.

If you use the 2-prim method, you will probably want to put a frame around them, because as alphas fade and cross over, you will be able to see parts of surrounding scenery flickering between the two prims.
.

Aha, that's a good solution. Now why didn't I think of that?

In 1 prim? How about using the inside and outside of a hollow box? Just put at least 2 images and this script in a prim. The script makes it a hollow box and sets the texture params correct.

integer Loop = 2;
integer side;
integer Textures;
float Time = 15.00;
string tex1;
string tex2;
float x;
 
default
{
	state_entry()
	{
		llSetPrimitiveParams([PRIM_TYPE, PRIM_TYPE_BOX, 0, <0.0, 1.0, 0.0>, 95.0, <0.0, 0.0, 0.0>, <1.0, 1.0, 0.0>, <0.0, 0.0, 0.0>] );
		llSetPrimitiveParams([PRIM_TEXGEN, ALL_SIDES, PRIM_TEXGEN_PLANAR]);
		llScaleTexture(0.1,0.1,ALL_SIDES);
		llSetPrimitiveParams([PRIM_SIZE, <0.01, 6, 4>]);					 
		llSetTimerEvent(Time);
		Textures = llGetInventoryNumber(INVENTORY_TEXTURE);
		tex1=llGetInventoryName(INVENTORY_TEXTURE, 0);
		tex2=llGetInventoryName(INVENTORY_TEXTURE, 1);
		llSetAlpha(1,4);
		llSetTexture(tex1, 4);
		llSetTexture(tex2,5); 
	}
 
	timer()
	{
		for (x=1;x>-0.001;x=x-0.001) llSetAlpha(x,4);
		tex1=tex2;
		tex2=llGetInventoryName(INVENTORY_TEXTURE, Loop);
		llSetTexture(tex1,4);
		llSleep(2);
		llSetAlpha(1,4);
		llSetTexture(tex2,5);
		++Loop;
		if (Loop == Textures) Loop = 0;
	}
 
	changed(integer change) { // something changed
		if (change & CHANGED_INVENTORY) { // and it was a link change
				 Textures = llGetInventoryNumber(INVENTORY_TEXTURE);
		tex1=llGetInventoryName(INVENTORY_TEXTURE, 0);
		tex2=llGetInventoryName(INVENTORY_TEXTURE, 1);
		llSetAlpha(1,4);
		llSetTexture(tex1, 4);
		llSetTexture(tex2,5);
		Loop=2;
		}
	}
}

I tried the 1 prim with the script but I get a script error making it. I dont know enough about scripting to see the problem. (

is it syntax errors? where is it telling you the problem is?

I checked and this is what is happening:

1. Load 2 pictures and the script into an object
2. Object transforms properly
3. First image displays fine
4. Timer begins
5. Second image displays fine
6. Timer begins
7. Error Message: Object: Could not find texture ''.

Then the loop stops.

If I change the loop to 1 instead of 2, it works fine:

integer Loop = 1;
CODE


I think since the first texture is texture 0 and the second is texture 1, when it tried to grab texture 2, it could not find it because technically, texture 2 is really texture 1. Works fine now.
