- What do you want to achieve? Like the title said, how? Like for example, player is in mobile, he tapped like 2 different buttons at the same time, how do you detect that?
afaik you cannot detect two separate buttons touched at once (in mobile atleast)
Then how are Battleground games able to do that, sometimes you get kicked when you do it.
Are these build-in buttons or developer created buttons?
I would recommend adding (if the UI is made by you) a local script inside the code, and whenever the button gets pressed it fires a remote event and sends it to the server.
If you need more understanding I recommend doing a os.time() feature so upon you clicking, it will register into the server. (You Can Edit that as you please)
Feel free to use my script if you need.
Set up
Local Script - TextButton
Server Script
Conclusion
Feel free to message me back if you need any help.
Edit
For different buttons to be hit just do the same thing as the Local script! 
If you want to do something else you can change where it kicks them and change it to whatever you want.
