changeset 25:aa3d837024a3
Scrolling by keyboard is now possible.
* Patch by DomtronVox.
* Added scrolling with the arrow keys.
* Added a slider bar in the settings menu to allow players to set the scrolling speed.
* Fixed an error that occurred when the ok button in settings was pressed.
* There is some kind of focus issue where opening the settings menu in-game causes scrolling to be disabled. Workaround is to change the scroll speed setting whenever you open the settings menu.
