How to do Hover-Text with Multiple Coloured Rainbow Effects

[Eisaki]

Does anyone know how to do the Multi-colour Changing Rainbow Effects on a Hover-text Script? Where is animated like and changes into different colours automatically? Would like to also know if I could change it to any of the colours I wish to use and they automatically change example it animates or flashes on it's own to blue to red to yellow to pink then start over the colour pattern again and so on. I want it to be a Hover text so I can change up the words at anytime.

It sounds as if you want to cycle through a list of colours.    If that's the case, try something like this, to run through the colours you've chosen and then start over.   You'll probably want to change the colours using a timer rather than a touch event.

integer iMax;
integer iCounter;
integer n;
list lColours =[
<1.0,0.0,0.0>,
<0.0,1.0,0.0>,
<0.0,0.0,1.0>
];

string strText ="Hello, Avatar!";
default
{
	state_entry()
	{
		iMax = llGetListLength(lColours);
		n = iCounter%iMax;//the "remainder" when you divide iCounter by iMax
		llSetText(strText,llList2Vector(lColours,n),1.0);
	}
	touch_start(integer total_number){			
		++iCounter;//advance the value of iCounter
		n = iCounter%iMax;
		llSetText(strText,llList2Vector(lColours,n),1.0);
	}
}

Adding to Innula's post, the entire string of a single prim's hovertext can only be one color at a time. So if you want to have the effect of multiple words or letters having different colors, they are actually separate prims each with their own hovertext.

And adding on to that, since the hovertext font is not monospace (Every letter has a slightly different width), the ability to have per-letter rainbow colors and the ability to change the text arbitrarily are (more or less) mutually exclusive, not to mention the letters won't fit together horizontally nicely unless it's a HUD or you're looking at it straight on.

Just some irrelevant style notes, but

1. n should probably be a local variable in this case, not a global one.
2. I'd do away with n altogether and just apply the modulus to the counter:

   iCounter = (1+iCounter)%iMax;

You can actually achieve consistent letter alignment regardless of view angle:

This has the six prims postioned at exactly the same spot with whitespaces used to position each letter. It's not something I would recommend but it is possible.

Silly me imagined using the position of the prims as the spacer rather than whitespace characters, dope. figuring out the correct spacing for each letter seems error prone and tedious. Good job!

Thank you but as I said, it's not something I would recommend. It's probably more of a curiosity than a useful trick. You can't get precise kerning this way and for some reason the letters aren't correctly aligned vertically. I don't know why but it seems that darker text is positioned slightly higher than lighter.

It's mostly an optical illusion: (Though it looks like specifically black text loses the "drop shadow" other characters have.)
