[Freeciv-Dev] Re: [PATCH] bugfix for wrapping problem

["Ross W. Wetmore" <rwetmore@xxxxxxxxxxxx>]

We should be careful to distinguish the critical objection in this
thread.

Wrapping is *good* when the coordinate is continuous in that direction.
Having tiles move off one side and onto another allows one to center a
field-of-view for improved local interpretation.

Drawing multiple images of wrapped tiles is *bad*, inconceivably moreso
when you aren't even bothering to simultaneously update all versions.

It might be noted that many fantasy games have a wizard spell to create
multiple images of a defender with the purpose of overloading and 
confusing an attacker and by so doing divert attacks from the true player. 
I really don't think you want to make Freeciv throw such spells at the 
poor user as a matter of course.

I might add, that if the coordinate doesn't wrap, then the map should
not as well. This is currently not the behaviour for a Donut-World or 
MAP_WRAP_Y.

Cheers,
RossW
