Tutorial: Robocraft borderless mode // ROBOCRAFT


Borderless Mode

Sometimes it’s desirable to run Robocraft in a borderless mode, also known as a borderless window or fullscreen windowed mode. This allows you to easily switch to other apps and reduces the chance of Robocraft freaking out. I like to have a web browser open on my second monitor and watch people play Robocraft on Twitch. Is that weird?

It should be noted that if you don’t want to go through all this trouble you can launch the game directly from Steam and it will ask you if you want borderless mode. I’ve never seen a game do this before, but whatever. OMG it’s alpha! Right?

Using the method described below lets you to launch Robocraft in borderless mode from outside of Steam. For example, you can pin Steam to the Start Menu and then launch Robocraft from the recent games list. I’m told this is how MLG Robocraft players do it.

Robocraft Borderless Mode Instructions

Step 1

It’s assumed that you can find Robocraft in the Steam game library. We need to make some changes to it. Open Steam, right-click Robocraft, and then open the Properties.

Step 2


Open Launch Options.

We need to add some launch options to to Robocraft, so click Launch Options.

Step 3

launch options

Add -popupwindow to Launch Options.

Enter -popupwindow into Launch Options and click OK. This tells the game to start in borderless mode.

Step 4

Amazingly, we’re only half way done. We still need to configure Robocraft. Launch Robocraft and open Settings.

Step 5

Uncheck Full-Screen mode in Robocraft settings.

Uncheck Full-Screen mode in Robocraft settings.

We don’t want to run in fullscreen mode, so uncheck Fullscreen. Also set the resolution you want to use. If you select a resolution smaller than the max resolution then the Robocraft will only take up part of the screen.

Step 6

Now we’re done. Close Robocraft and start it again. The game should now be in a borderless mode. I hope Freejam makes this easier!

BTW, you can add -popupwindow to your Windows shortcut if you have the old launcher.

    Thanks, use this method with bilagaana’s comment. (You might wanna download notepad++ or some program like that, so you can open the Settings.json file)

    Still works, just have to modify the Settings.json file in ..\Robocraft\EasyAntiCheat\Launcher\Resource. Change “parameters” : “” to “parameters” : “-popupwindow”.

    This doesn’t seem to work, it doesn’t change anything with the startup parameter it isn’t borderless. Also any borderless program i use doesn’t really work, everytime i click on my other monitor it still minimises Robocraft.
