Map Generator- Please Critique!

Ok, so World Wrap is basically implemented using the 3 map solution. There is a barely perceivable flicker as I teleport back to the middle map which is more obvious when zoomed out and you can see a whole map width. Given that the map is the smallest size with no bells and whistles, this solution may not work out in the end, but it works as a proof of concept and testing ground until I figure something better out. Could use a variation of zeOrb’s idea if I can be confident that all the math and array updating won’t bog things down(or melt my brain).

Sometime soon, hopefully tomorrow, I will create a new Map Generator post with an updated look at my current generation process and what I will work on next. I will leave the OP of this post untouched so people can look at it for reference.
