[Feature] Use screen scrolling

[Spikeone]

Ich spiele auf einem Macbook, das hat nur eine Maustaste am Touchpad. Daher ist bewegen auf der Karte nur mit den Pfeiltasten möglich.

Wäre es möglich auch die Scrollevents (Oben, Unten, Links, Rechts) zum bewegen der Karte zu verwenden? Das würde insbesondere auf Notebooks die Zwei-Finger-Scrollen unterstützen das spielen erheblich verbessern.

Vielleicht schaue ich mir den Code mal an und gucke ob diese Erweiterung meine erste Siedler2.5 Contribution wird ;) Die Komplexität dürfte wohl überschaubar sein.

This is currently not possible. There is only SDL 1.2.15 and SDL 2.0. 1.2 does not have horizontal scrolling and 2.0 requires many changes in the code. -> Postboned

Note: scrolling means usually zoom. So I think that would be bad too use them for moving So I'm against this change

[Spikeone]

I don't think he means zoom but map view scrolling. As he has no right click, he can not move the map view. Like in a lot of other games he could move the cursor to the one screen border to scroll that direction. I'd not use it but for mac it seems quite reasonable.

[Flamefire]

Understood that. But he wanted to use scrolling for moving which is counterintuitive. The screen border movement sounds like a good idea. Maybe optional? I'd say not but it is a change from the original

[Spikeone]

Ah, now I get it, sorry, agreed thats not intuitive. But screen border movement (which shouldd be an option, so anyone can turn it on and off, should be on by default on mac then?) still sounds good for me, also if not really needed, is it (only good for touchpads, isn't it?).

[Flamefire]

Alright, then border scrolling it is.

Please add this only as an option one can enable / disable :)
