Splitscreen. How do you select all player indexes? 4.16

Hello.
Here is my problem. I would like to be able to have any player step into a Box Collision and something happen. (In this case it’s a Launch Pad from this [tutorial][1])
I tried thinking up an array to get it to work but alas it was a failure. The Get still had a int value that got called over the Array.
If there is something else that I could plug into the Player Index to make it select all players that would be great. Thanks.

Did you ever end up finding a solution to this? I have the same type of issue xD
