Discussion: Free Photo Viewer Script

Okay, a friend of mine had a broken picture viewer, so I made my own "HiroTV".

Below is the notecard instructions and then followed by the source code. This is freeware, not supported, please have fun with it! =)

1. SETUP

Step 1: Drop the HiroTV script into any prim you'd like to display pictures on.
Step 2: Add pictures.
Step 3: say, "HiroTV:reset"

-------------------------

2. COMMANDS

NOTE: All commands are case sensitive

HiroTVetname
--------
Changes the name your HiroTV responds to. This is useful if you have more than one up in a room.
For example -
HiroTVetname:MyTV
changes the name to "MyTV". All commands now will begin with "MyTV" instead of "HiroTV".

GetHiroTVName
--------
If you've forgotten the name of your HiroTV, you can use this command and any HiroTV in range that you
own will tell you its name.

HiroTVetcolor
--------
Changes the color of the floating text, using 0-255 values for Red, Green, and Blue.
Example -
HiroTVetcolor:255,255,255
changes the floating text to white.
HiroTVetcolor:255,0,255
changes the floating text to magenta
HiroTVetcolor:-1
turns off the floating text. You can turn it on again by simply doing the setcolor command with what color you want.

HiroTVettimer
--------
Changes how many seconds between change of picture
Example -
HiroTVettimer:10
changes the time between display to 10 seconds

Is this the same thing thats in those avalon phones?

Sorta kinda. But:
(a) You can use it in any prim, not just a tiny screen.
(b) It's freeware. Have fun.

I loved this device and it worked fine after I fixed what seemed to be "syntax errors" -- the separation of the word 'selected' in one place and removal of the line at the end. If you follow the directions precisely it should work and it's a great thing for events because it makes a slideshow that you can leave running with 2 or 10 or more seconds between shots.

Does this random pick or take pics next in line?

didnt work fo rme and did excatly what the directions where

yay thanks Hiro - it worked perfectly

How would one add buttons to this?

So as to cycle through the images I mean : )

I don't understand scripting, but I really like this. Can anyone tell me if there is a way to stop the floating text, and not bust the script?

Thank you bunches
(hugs)

You can use the command HiroTVetcolor:-1
or you can change the script.

The floating text is control by the updatetxt function. You can just set it to display blank text by adding r= -1 at the beginning of the function.

updatetext()
{
    r = -1;    //always display blank text comment or delete this line to return to normal function
    if(r==-1)
        llSetText("",<0,0,0>,100); 
    else
    llSetText(llGetInventoryName(INVENTORY_TEXTURE,( selected - 1))+
            "\nPicture "+(string)selected+" of "+(string)numberitems, <r,g,b>, 1.5);
            
    llSetTexture(llGetInventoryName(INVENTORY_TEXTURE,  (selected - 1)),ALL_SIDES);
}

Listening on channel 0 incase the owner wants to reset the script seems a bit of a waste. Wouldn't it be better to reset on inventory change or touch by the owner (unless flicking through pics is needed, but then they change on their own anyway).

Here's some much smaller code that does the same thing without the hover text or the listener. If you want hovertext, it's a one line addition.

integer numberitems = 0;
integer selected = 0;
integer switchtime = 5;

switchpic(){
    selected++;
    if(selected>=numberitems)
        selected=0;
    llSetTexture( llGetInventoryName( INVENTORY_TEXTURE, selected), ALL_SIDES);
}

default{
    on_rez(integer rez){
        llResetScript();
    }

    changed(integer change){
        if(change & CHANGED_INVENTORY)
            numberitems=llGetInventoryNumber( INVENTORY_TEXTURE );
    }

    state_entry(){
        numberitems=llGetInventoryNumber( INVENTORY_TEXTURE );
        llSetTimerEvent(switchtime);
    }

    touch(integer touches){
        switchpic();
    }

    timer(){
        switchpic();
    }
}

Thank you ver much Destiny I will try that.

edit: Thank you it worked. I'm sorry for asking a dumb question. I looked closer at the instructions and found the command listed there as well.

Awesome thanks for the script...had it up and running in my house in 5 minutes

hey what about if i only want to the pictures display in the front of the object and don't in the sides and back and keeps the last textures right?

Change the llSetTexture line to use the side number you want rather than ALL_SIDES

Worked like a charm! Switched the ALLSIDES to 2, to show only on the side facing me, painted the rest of the prim black, and put it behind a picture frame prim I designed.
