Invisible picture

[evildogbot100]

How do I make invisible rail? I tried changing a lot of filename into "__core__/graphics/empty.png" but I got this error. The given sprite position (left_top = 1x0) is completely outside the actual sprite image (size 1x1).

I think you need to change the image size to 1,1 too, not just change the file.

I did, also tweaking with shift amount but nothing happen, the error message still happen.

Some entities has hardcoded picture dimension. Use 100% alpha for invisible entities.
