How to offset using marquee

[yitzil37711700]

I am trying to create a seamless tileset for a videogame, and I don't want to have to make a new file for every tile.

Is there a way to use "offset-Wrap around," but only wrap around inside the marqueed area? If I have to code, I'm ok with that.

OK, I just learned something. I always assumed offset was document only. It is selection based as shown below.

Just make sure your selection is a square by holding the shift key as you drag.

Thanks, but I only want it to wrap around INSIDE of the selected area.

From what I can tell, you're wrapping the entire canvas.

No, I create a new document, filled it with a gradient, then dragged out a selection in the middle and applied the offset to the selection. As you can see the canvas did not offset.

The resulting selection can then be copied or moved to a new layer. That new layer can then be exported.

I assume what you are trying to do is create a storyboard or sprite sheet. If so, contact sheet II can help combine the resulting images into a strip.

I am not sure that I am understanding what you want to get as an end result exactly, and Select > Modify > Contract seems too obvious to be the answer.  Can you elaborate on where you are trying to get to — what your end result needs to be?  Are you trying to make a gap between the tiles for a grout effect, for instance?

[BTW]  I like Silkrooster's post, and agree that is worth having a closer look at.

I want to achieve this efect:

But within a larger canvas (only having selected area do the "pacman" effect).
