This noticeboard is the first of a new generation of mesh based, low prim, low lag, re-sizable & configurable boards. Typically the number of prims appearing on land costs depends on the number of characters displayed. Each mesh prim can display 16 characters at a land cost of 0.5 prim. So here's the formula:
land cost = 2 + (no. of lines x characters per line) / 32
Examples:
A 5 line by 48 character display = 2 + (5 x 48) / 32 = 9.5 prims (i.e. 10 prims)
Setting up
------------
You need to do this once per different noticeboard you want:
1. Rez the Mars NoticeBoard object (don't acknowledge the "Link and delink" request just yet, also don't rotate or resize it yet)
2. Edit the board & look at the Description in the General tab
3. Adjust the description text to suit your requirements: linesxchars,channel
Where: lines = number of lines in the display (1 - 100)
chars = number of characters per line (1 - 1600) in multiples of 16 (otherwise it will be rounded)
channel = private channel number (not zero) to receive commands
eg: our 5 line by 48 character display using channel /1 would be:
5x48,1
4. (optional) you may drag a texture to be the background into the Content tab. Add a texture into the noticeboard contents if you want a background on the board
5. OK the "link and delink" request to rez the mesh character displays
Note: If you accidentally cancel the "link and delink" request just reset all scripts (edit the board, & click Reset Scripts in the Content tab)
6. Once rezzed you may move, resize, rotate, edit linked prims etc as you wish.
Note: using the RESET PRIMS option will re-rez the mesh character blocks based upon the General/description field. Also it reverts to default orientation & size.
Operation
------------
Once set up the board will be listening on the channel provided and response to touches by the owner. Options available by menu are similar to those typed on the private channel:
Menu when clicking the board :-
CLEAR - clears display (if a title is set then the title appears on the first line)
ENTER TEXT - displays textbox to enter text into the "next" line on the display
TITLE - Clear display and set a title. If blank the title is switched off
COLOUR - Change colour (note UK spelling) of all characters (see channel command for individual lines)
NEWS/NEWS OFF - switch news option on/off. This displays whatever is in the notecards in the board - changes to next notecard every 5 minutes
NEXT NEWS - displays the next news notecard (same action when non-authorized personnel touch the display)
SCROLL/NO SCROLL - switches scrolling on or off
GROUP/OWNER ACCESS - toggles between group or owner only access to the board
TEST DISPLAY - display filled with test text
RESET PRIMS - deletes text prims & re-rezzes them according to the General/description field
CENTERED/LEFT - centres or left justifies future text. Note title is not centred.
Channel commands as with the menu with following differences:
COLOUR line,<red,green,blue> - to change a specific line's character colours (numbered from zero)
To enter text just say on the channel (no prefix necessary)
eg: from our above example on channel 1
/1TITLE Welcome to Mars Productions
/1COLOUR 0,<1.0,1.0,0.0> - yellow title
/1SCROLL - text will scroll below title
/1This is line one
/1This is line two
/1This is line three
/1This is line four
/1This is line five - would cause our 5 line display to scroll
Group access:
When this mode is switched on by the owner then those with the same group activated as the display will be able to add text, clear the screen & switch on/off news. They will not be able to change colours, titles or re-rez the characters
- Low land cost (32 chars per prim + 2)
