Electricity Update

Dec 8, 2025

Now you can add electric components to your Simulo simulator! You can also use explosives now, giving temperature a utility within the sandbox

You may experience some bugs with the undo, try not to spam it for now. We are currently working on improving this, so stay tuned.

Next up this week is electrocution, which will allow electricity to interact with ragdolls, shocking them and damaging them!

However, this very compacting is what caused the problem! So, we are no longer using that compacting, and the code is now distributed as-is.

I've tried updating my drivers, deleting and reins...
