Algodoo

Ok, I have been able to confirm it works, but still feel free to tell me if it works on your end!

2 downloads? my scene "Welcome scene from phun v4.21" have more downloads.

If you employ this in any or all of your published scenes, then NO ONE will be able to play them because the objects with that special code will delete as soon as Algodoo is RUN! Not only will no one be able to copy the scene, but they also won't be able to play it! So, what's the point?

Here is a scene that I posted back in 2014: COPY PROTECT YOUR SCENE! . It shows a couple of ways to protect your scene, and some users also provided some ideas in the comments section. Take a look, it might be helpful.

Xray - This was only a silly experiment as the title suggests, it's my first bit of coding that works outside of where I can see! I will probably not use it due to how wide open the script is, but I may use anti-copy stuff, maybe a hidden object in the scene defines a variable as true, and if a wide open object reads that variable and confirms it's true, the stuff will run as normal, but if it's false or undefined, some text box will inform that the content was stolen. I've had at least one confirmed thievery, and one uncertain one.

MyNameIsThis - this scene was posted just an hour or so ago. Not many people have been on Algodoo long enough to stumble upon it. Some of my scenes have thousands of downloads! …If I recall correctly.

UDG04 -- Okay, no problem. I was just trying to understand how your idea for copy-protection works. As you can see from my old scene, there are a lot of different ways to do it. Some better than others.

I usually don't worry much about anyone stealing my scenes because most of them operate mostly on scripting which most of the kids don't use. So, if my scene or parts of a scene get used and posted, I will know it immediately. Once you start to use scripting, I think you will also realize that it becomes much more difficult for people to steal them.

It deletes itself even on this scene
