llSetText

Summary

Function: llSetText( string text, vector <span title="color in RGB, <0.0, 0.0, 0.0> = black, <1.0, 1.0, 1.0> = white." style="border-bottom:1px dotted; cursor:help;">color, float alpha );

0.0	Forced Delay
10.0	Energy

This function is used to set text to display over an object in SL.

• string	text	–	text to display between the quotes
• vector	color	–	color in RGB, <0.0, 0.0, 0.0> = black, <1.0, 1.0, 1.0> = white.
• float	alpha	–	visibility, 0.0 is fully transparent and 1.0 is fully visible.

Specification

Displays text placed over object -- programmer specifies text, color and visibility/transparency.

Caveats

The floating text is a property of the prim and not the script, thus the text will remain if the script is deactivated or removed. To remove floating text, one must assign an empty string with llSetText("", <1.0, 1.0, 1.0>, 1.0);

Examples

Example colors:

vector white = <1.0, 1.0, 1.0>;
vector red = <1.0, 0.0, 0.0>;
vector green = <0.0, 1.0, 0.0>;
vector blue = <0.0, 0.0, 1.0>;
vector grey = <0.5, 0.5, 0.5>;
vector black = <0.0, 0.0, 0.0>;

llSetText("I am on", <1.0, 1.0, 1.0>, 1.0);

<1.0, 1.0, 1.0> represents the values for red, green, and blue. <1.0, 1.0, 1.0>, means "white" and <0.0, 0.0, 0.0> means "black".

llSetText("I am off", <0.0, 0.0, 0.0>, 1.0);

The 1.0 is the alpha setting. 1.0 means fully opaque, and 0.0 would be completely transparent (invisible).

Example of how llSetText could be included in default code:

default
{
    state_entry()
    {
         llSay(0, "Hello, Avatar!");
         llSetText("Prize Box", <0.0, 1.0, 0.0>, 1.0);
    }

    touch_start(integer total_number)
    {
         llSay(0, "Touched.");
    }

}

Notes

Most commonly, this is included in the default code for an object (see example above).
