I really want to get Prison Architect, but after watching Yogscast Sjin play it I've noticed that he says the scroll wheel and middle mouse button are prominent buttons. I have a trackball that has neither a scroll wheel nor middle mouse button. I don't want to buy a game I won't be able to play.

Is there a way to change the control scheme in the game to avoid the use of these particular controls?

  • The game is still alpha phase; beta phase you will probably have better luck with key mappings. You could buy a decent mouse for $20 and never have the issue again, but if you don't want to support the game in its current state there's nothing wrong with waiting until it suits your gaming setup.

  • Experimented a bit and discovered some unlabeled bindings. Edited my answer to reflect.

You can use WASD to scroll the map, Q and E to zoom, and R to rotate items. No middle mouse button or scroll wheel needed.


You can also use 1, 2 and 3 to change the game speed.

As @harbichidian points out in the comments, use Space to pause/unpause.

  • Toggling pause via the keyboard would be great. If anyone knows a key binding for that, please post it. Sep 18, 2014 at 22:23
  • Spacebar toggles between pause and your current speed.
