Non-Portable Script

Here is a generic little function that can prevent people from ripping your scripts from the items you make and stuffing them into Objects that you did not create.
Change Variables and Funcionality as needed.

//  This little function is based on something I use to prevent
//  some of my scripts from being ripped out of my creations
//  and re-used in something I did not make.
//  This particular function is not 100% foolproof, but generally gets the job done.
//  Feel free to mod this to make it 100% foolproof for your usage.

CheckSum()
{
    key ObjectCreator = llGetCreator(); // The UUID of the Creator this script is in (might not be you!)
    key Scripter = "YOUR UUID HERE";    // Hard-code YOUR UUID here
    key ObjectOwner = llGetOwner();     // The Owner of the Object this script is in
    
    if(ObjectCreator != Scripter)       // The Creator of the Object this script is in does not match the Script Creator (you)
    {
        // UNCOMMENT ANY OPTIONS BELOW TO TAKE THE APPROPRIATE ACTION (OR MAKE YOUR OWN)
        
        llSay(0, "You have violated the rights to use this script."); // Say a Message to the Owner of this violation
        //llInstantMessage(Scripter, llKey2Name(ObjectOwner) + " has violated your script usage terms."); // Send yourself a message about the violation
        //llRemoveInventory("THIS SCRIPT NAME"); // Delete this script from the Object's Inventory
        // llDie(); // Delete the Entire Object
        
    }
