SDK3 World Trigger trouble

Hi there. I’m currently working on a world of my own and could never understand how to use the trigger function in the sdk3. I could get it to work on the sdk2 but don’t want to start over again. I just want to be able to turn the mirror on/off and be able to teleport players from one location to another. Can anyone help me with this?

Hello,
I think this tutorial is what you need to turn on/off mirror using Udon : (NEW VERSION IN DESCRIPTION) VRChat Udon Tutorial | Basic Buttons - YouTube
