How to disable splitscreen?

[Thirsty]

The game only lets me use my controller if I am "player 2" or something, it forces player 1 to use keyboard and mouse, when I am player 1, so I can't do comps on my own!

Two possible solutions:

1.
Plug in all gamepads you have used on this PC
uninstall each one from device manager. unplug the controller after you uninstall it.
Uninstall the controller you want to use last and unplug it.
reboot.
plug in the controller you want to use (let windows install it or install driver if applicable)
in control panel, go to the "Set up USB game controllers" section
click "Advanced" select your controller, then "OK"
reboot. (for good measure)
Try RL again! hopefully it works now.
In the future any time you plug in another gamepad, make sure your original player 1 pad is plugged in and on.

2.
First install x360ce 32 bit you can easily find it using google or any search platform. after installing extract it to C:\Program Files (x86)\Steam\steamapps\common\rocketleague\Binaries\Win32. Open the program and press your controller's keys and check that everything is working, make sure your controller is on Controller 1 top left!. Below the "Controller 1" tab there are sub tabs go to " Controller (Controller name)" and you will see on your right a "Map To" tab switch that to 1. Make sure to save and enjoy! P.S you can add another controller and map it to 2 the exact same way and have a splitscreen sesh

Hope either of these work!
