changing textures but owner only permissions

I used the simple script in the solvo library to swap textures, problem is anyone can. I want it to be set to just me to touch to swap. Any ideas?

Add this test to the touch_start event like this:

    touch_start (integer total_number)
    {
        if (llDetectedKey (0) == llGetOwner ())
        {
            //Texture changing code goes here
        }
    }        

touch_start (integer num)
{
     if(llDetectedKey(0) == llGetOwner())
     {
          // Do whatever it takes to change the texture
     }
     else
     { 
           llInstantMessage(llDetectedKey(0), "Sorry, only the owner can change textures on this object.");
     }
}

Or words to that effect.........

ETA: HAH! Pete got there first.

this is what i made but it wont run , gives me error.

touch_start (integer total_number)
{
if (llDetectedKey (0) == llGetOwner ())
{
//Add script and up to 100 textures to object///

integer number;
string name;
integer choice = 0;

default
{
    state_entry()
    {
        number = llGetInventoryNumber(INVENTORY_TEXTURE);
        number -= 1;
        name = llGetInventoryName(INVENTORY_TEXTURE, choice);
        if (name != "")
        {
            llSetTexture(name, ALL_SIDES);
            choice = choice + 1;
        }
    }

    touch_start(integer total_number)
    {
        if (choice < number)
        {
            name = llGetInventoryName(INVENTORY_TEXTURE, choice);
            if (name != "")
            {
                llSetTexture(name, ALL_SIDES);
                choice = choice + 1;
            }
        }
        else
        {
            name = llGetInventoryName(INVENTORY_TEXTURE, choice);
            if (name != "")
            {
                llSetTexture(name, ALL_SIDES);
                choice = 0;
            }
        }
    }
    
    changed(integer change)
    {
        if (change & CHANGED_INVENTORY) 
        {
            llResetScript();
        }
    }
}
}
} 

That's because you didn't incorporate the code that Pete and I gave you. You stuck it outside the script. Do it like this ....

integer number;
string name;
integer choice = 0;

default
{
    state_entry()
    {
        number = llGetInventoryNumber(INVENTORY_TEXTURE);
        number -= 1;
        name = llGetInventoryName(INVENTORY_TEXTURE, choice);
        if (name != "")
        {
            llSetTexture(name, ALL_SIDES);
            choice = choice + 1;
        }
    }

    touch_start(integer total_number)
    {
        if (llDetectedKey (0) == llGetOwner ())
        {
             if (choice < number)
            {
                 name = llGetInventoryName(INVENTORY_TEXTURE, choice);
                 if (name != ""
                 {
                     llSetTexture(name, ALL_SIDES);
                     choice = choice + 1;
                 }
            }
            else
            {
                 name = llGetInventoryName(INVENTORY_TEXTURE, choice);
                 if (name != ""
                {
                     llSetTexture(name, ALL_SIDES);
                     choice = 0;
                }
            }
         }
         else
         {
              llInstantMessage(llDetectedKey(0), "Sorry, you are not allowed to change textures on this object.";
         }
    }
    
    changed(integer change)
    {
        if (change & CHANGED_INVENTORY) 
        {
            llResetScript();
        }
    }
}

thank you all the ones inworld who helped me too. I admit I know nothing of this other than cut pates and hope. It works now very well. Now if I could just get a linked 2 prim object to spin like a propeller on a airplane, not a helicopter (up down plane not horizontal)

I have been able to get a prim to rotate the right way by itself but when linked to say a center hub only the hub spins and not the propeller. Does that make sense at all?
