Could be useful but need to be much more advanced. Like saving the original terrain type and the lastly changed and the current type. And like regionally change terrain with specific iteration delay: within rect, circle, etc. And doing nothing in the constructor method seems weird. I don't recommend the use of struct in this case, hashtable would be better. You also can utilize TileDefinition by IcemanBo for better accuracy, it's not approved yet alright but I guarantee it's ready to go resource.

I want to make something like this as well actually, but seems like somebody else has managed to submit one :(

- In the script description i put: // Change the terrain texture without lost the original set. ^^

- Ok i'll see how func this.

- :( xd
 
DimensionalArray isn't approved so why not use Table instead and then use TableArray or HashTable to have a chance of getting approved?

could have been much better if it uses TileDefinition, because of this:
JASS:
            local integer tile
            if(xy<0)then
                set tile=R2I(mincord)
                loop
                    exitwhen(tile>=0 or tile>=xy-64)
                    set tile=tile+128
                endloop
            else
                set tile=R2I(maxcord)
                loop
                    exitwhen(tile<=0 or tile<=xy+64)
                    set tile=tile-128
                endloop
            endif
            return tile
TileDefinition's GetTileId does it much better

*I should start writing the TileMap now :V
 
It should use TileDefinition and Table.

TileDefinition to get the index of a tile, and then only a single array is needed, so no multidemensional array. But as default array size is limited one single Table can be used to solve this.

I believe it would be handy if user could set an option to auto detect all default terrain tiles onInit.
Or maybe at a given rect which is given as parameter. It would be quite a bit effort for the user to write an algortihm to get default terrain first of all terrain tiles he needs, because eventualy even one needs to care of OP limit. So automated function would help.

Getting the origin terrain type is probably handy sometimes. Though it is also pretty specific in terms of usage -- the elemental thought is to cache an integer (terrain type) based on keys x/y (coordinates) and to call it later with respective keys.

The changes we talked about above would bring some more comfort, and would be definitly still good to see, but honestly I don't see it as useful enough for JASS submissions.
Though it still might have some use in case or someone might be interested in concept... I would move this to The Lab.
