# Copying Arrays

Get help using Construct 2

### » Wed Feb 06, 2013 9:26 pm

I have two arrays BigArray is 100x100, and SmallArray is 10x10

Can anyone suggest the best method to copy a 10x10 portion of BigArray into SmallArray.

I have tried ForEach, For, loopindex.... and cant get anything to work.

Suggestions would really be appreciated before i pull all my hair out

offsetx = X Location to Start Copy to in the BigArrray
offsety = Y Location to Start Copy to in the BigArrray

For "x" 0 to 9:
For "y" 0 to 9:
BigArray((offsetx + x), (offsety + y)) = SmallArray(x,y)

This is one way to do it where COL and ROW is the top left position to copy from.

local number COL=5
local number ROW=10

SmallArray: For each XY element
--- SmallArray: Set value at (SmallArray.CurX, SmallArray.CurY) to BigArray.At(COL+SmallArray.CurX, ROW+SmallArray.CurY)

RangerJim Thanks, would the following (copying portion of big into small)

For "x" 0 to 9:
For "y" 0 to 9:
SmallArray(x,y) = BigArray((offsetx + x), (offsety + y))

would this equate to this:

Where the Array within the For loops is smallArray

I think I have problems with the syntax relating to arrays

Rojohound... that works. Although the above For loop did not for the alternative For each loop does. Must be my interpretation of a For loop that's in error. Thanks.
