so check the steam controls by pressing the bottom left … button. Examine the controls for Factorio, are the steam deck controls mapped to mouse and keyboard or is Factorio receiving the actual gamepad inputs without them being translated?

From there you can just figure out which binding is for fire with the keyboard and map that to a steam deck button that makes sense for you, or you can look up the gamepad bindings in factorio and figure it out that way.

According to the controller settings it’s R1 on my steam. Go look in options and controller for some other nice things you can do. I have nearly all experience on keyboard though as Factorio with controller configuration is really just. It made well Imo

You need to hold R1 and tap R2.

The default gamepad controls are kinda ass.

Is this like the “noob bridge” from metroid? 😀
