Hi everyone! While I was working on my Lost Industry 2 project I made this small little perfab. It
also have a feature, if you put down multiple plug perfabs, every part is named differently, so you don't have to worry
about that. It's easy to install, just take that .vmf and put it into the folder called "Perfabs" (\Steam\steamapps\common\Half-Life 2\bin\Prefabs). How to use it? It's fairly simple. Let's say you wanna activate something, you want an explosion to happen when you plug it in.
Put down an env_explosion and name it for example: "exp".
Put down my perfab, and find a trigger called: plug_trigger_(number)
Go to the "Outputs" tab and click "Add"
On-StartTouch | exp | Explode
I hope I made your life easier, you can mess around with it however you want. You are free to use it, you don't need my permission. Have a great day!
