llSetText

Summary

Function: llSetText( string text, vector color, float alpha );

0.0	Forced Delay
10.0	Energy

Displays text over a prim with specific color and transparency (specified with alpha).

• string	text	–	text to display between the quotes
• vector	color
• float	alpha

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);
• Vertical whitespace is removed from the end of the text string, so if you want vertical whitespace put any character (like a space) on the last line.
  • Bad: llSetText("Monkeys\n\n\n\n\n", <1.0, 1.0, 1.0>, 1.0);
  • Good: llSetText("Monkeys\n\n\n\n\n ", <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.");
    }
}

By default the floating text will appear on a single line. However, the floating text can be spread over multiple lines by using a line break "\n".

     llSetText("I am \n on two lines!", <0.0, 1.0, 0.0>, 1.0);
