Text Scroller

Text Scroller ( V1 )

Updated: 24 April 2010 by The Creator Fred Gandt

All these scripts should be compiled as MONO

A simple text display object that scrolls text (applied as a texture) from right to left (like those LED signs) in a continuous loop.

• Touch start/stop.

The Charsheet Texture

• I am a scriptor, not a texturizerer. I created a very simple Charsheet (Character Sheet) to get you going but, it isn't very good *grins*. You will probably want to replace it.

• The texture MUST be 10 characters by 10 characters (you may have empty spaces so, 56 chars is fine so long as the grid is the full 100 spaces).
• Unlike the texture I have supplied...ALL the chars should be perfectly evenly spaced and not spreading into the neighboring spaces.
• This is the texture supplied. You don't need to copy this. The script already has the UUID in it.

• The display scripts contain a string that is in the exact same order the chars are read from top left to bottom right (row by row, not column by column).
• HAVING THE SAME ORDER OF CHARS IN THE TEXTURE AND STRING IS VITAL.
• The order you choose is entirely up to you as long as the strings in ALL the display scripts match the order of chars in the texture.
• Don't forget to include a blank grid space on your 10 x 10 texture for a space "character". There also needs to be an empty space (in the correct place) in the scripts.
• In the display script strings there are two characters that must be treated unusually. The \ and the " must have a \ placed before them.
  • Example "ABCabc123.,:\"\\/| " Note the included space and the way the \ and " have a \ before them.

Functions Used

1. llSetPrimitiveParams - Set shapes, colors, textures and other parameters of the prim the script is in.
2. llRemoveInventory - Remove the named inventory from the prim contents.
3. llGetScriptName - Returns the name of the script that calls the function.
4. llSubStringIndex - Searches a string for a test and returns the index (or -1 if not found)
5. llRound - Returns a classically rounded (up or down; whichever is closest) float as an integer.
6. llGetLinkNumber - Establish the link number of the prim the script is in.
7. llGetSubString - Returns the part of the source string specified.
8. llSetLinkPrimitiveParamsFast - Set parameters in any prim in a link-set without enforced delay.
9. llGetInventoryName - Returns the name of the specified inventory type at index.
10. llStringLength - Establish how many characters make up the source string.
11. llGetNotecardLine - Requests the string data on line of named notecard and (if successful) dataserver returns the result.
12. llMessageLinked - Send a message to defined links (or self) which are picked up by link_message
13. llSetTimerEvent - Establish a repeating time frame that on each pass will trigger timer
14. llResetScript - Wipe the memory and start from the word "default".

Events Used

1. state_entry - Triggered when entering the state this event is in.
2. link_message - Triggered if llMessageLinked sends a message to the link containing this event.
3. dataserver - Triggered with responses to requests for data made by various functions.
4. timer - Triggered if a set time has elapsed then again after that time elapses again ad infinitum until the set time is zero.
5. touch_end - Triggered by an agent left clicking the object containing the script.
6. changed - Triggered by various changes that the script can sense.
