Here's how it works...
You'll have to make an image that has a center piece that is tilable (or stretchable) and set the margins of the edge (top, bottom, left and right).
Something like this: dropbox.com/s/ebnmh526kjren ... .capx?dl=0
Hope this helps. Cheers!
Works perfectly exactly what i wanted! Thank you.
I have one issue though with replacing the blocks. Is there a quick way to replace everything in the events sheet with something else. I tried right clicking and replace object but that only shows the tiled background.. Probably me being new to it and i am missing something. Also tried replacing everything in the events sheet individually with"Ground" for this case. As i want to just replace "Block" with "Ground" everywhere.
